New Audi A3/S3 Facelift In Depth
Press Release


Fresh dynamics for even greater driving pleasure

The Audi A3 is a successful model – and has been for over a decade. The first generation made its debut in 1996; it immediately opened up its own market segment, that of premium, compact vehicles for individual, demanding customers. In 2003, Audi launched the second generation of the three-door A3; one year later, this was followed by the five-door Sportback. Over the years, the model series has enjoyed outstanding success – 230,849 vehicles were manufactured in 2007 alone, the fourth record year in a row. At the end of 2008, the one millionth second-generation A3 came off the assembly line. Audi is now continuing to extend its position.

The A3 and A3 Sportback bodies clearly reveal the many details of the streamlined, sporty profile. The engine hood and the fenders are more expressive, whilst the bumpers and the single-frame radiator grille have been finely upgraded. An elegant trim – the "wing" – underlines the high technical perfection of the new headlamps. Daytime running lights are standard; if optional bi-xenon headlamps are fitted, this is implemented by means of seven LEDs. On the flanks, exterior mirrors with integrated turn signal lamps, modified door handles and powerful wheels emphasize the main features. The wheels fitted in the sporty Ambition equipment line have a diameter of 17 inches and are manufactured from cast aluminum.

Modifications to the bumper and the lamps lend the rear end an even more striking look. In the A3 Sportback, innovative light guide rods form a flat corona, which generates an unusual optical effect in the dark. In the three-door A3, the trunk lid has been provided with a new light edge. The design modifications have extended the A3 by 25 millimeters (0.98 inches) to a length of 4.24 meters (13.91 feet), whilst the A3 Sportback (4.29 meters (14.07 feet)) has grown by six millimeters (0.24 inches) – its sporty proportions therefore remain virtually unchanged. Four new colors supplement the color charts.

The interior welcomes passengers with an atmosphere of sporty elegance and top quality. The air vents, the light switch and the center console have been refined with discreet chrome strips; the switches and controls beneath the audio system have been redesigned. The instruments display black dial faces and red pointers. A gear change display in the driver information system helps to achieve an efficient driving style. A driver information display with high-resolution, white lettering is fitted in the Ambiente and Ambition equipment lines. The spectrum of seat coverings rages up to Fine Nappa leather for the sports seats. New, standard trim variants in pearlescent, micrometallic and Vavona wood are available, whilst Aluminum Medial and burr walnut inlays are available as options.

With a volume of 350 to 1080 liters (12.36 to 38.14 cubic feet), the Audi A3 offers the largest luggage compartment in its class, with the Audi A3 Sportback offering 370 to 1100 liters (13.07 to 38.85 cubic feet). These values are a few liters lower in the models with quattro drive due to the special rear axle. A particularly practical feature is available in the front-wheel-drive versions – a reversible load floor, which can be used as a drip tray for damp objects. Roof railings and a panoramic sliding roof are also available for the versatile A3 Sportback.

Eight powerful and efficient engines

As before, Audi will be equipping the A3 and the A3 Sportback with eight engines. Six of these are four-cylinder direct injection engines with turbocharging. Their abbreviations, TFSI and TDI, symbolize the combined strengths of Audi engine technology – they stand for performance and tractive power, for dynamics, smooth running characteristics and efficiency.

The range of gasoline engines is broad-based. The 1.6 has an output of 75 kW (102 hp), the 1.4 TFSI 92 kW (125 hp), the 1.8 TFSI 118 kW (160 hp), and the 2.0 TFSI 147 kW (200 hp), whilst the 3.2 generates an output of 184 kW (250 hp) from its six cylinders. The three diesel engines are also high-powered.

The 1.9 TDI has an output of 77 kW (105 hp), with the 2.0 TDI offering 103 kW (140 hp) or 125 kW (170 hp) depending on specifications. In the two reengineered two-liter TDI engines, a new common rail injection system ensures highly-cultivated operation.

All engines combine a powerful character with high efficiency. The 77 kW (105 hp) diesel engine is also used to power the Audi A3 1.9 TDI e, which consumes just 4.5 liters of diesel per 100 kilometers (52.27 mpg) thanks to its special fine-tuning. The 1.8 TFSI and 2.0 TFSI engines have been optimized in terms of friction. The majority of the engines' fuel consumption values have been reduced significantly, by up to 15 percent.

High-tech from Audi: The new power transmissions

The range of power transmissions has been recently extended. Five of the eight engines are coupled to six-speed manual transmissions as standard; the 1.6 and the 1.9 TDI engines are fitted with a five-speed transmission, whilst the 3.2 is equipped as standard with the S tronic dual-clutch transmission, which is now available as an option for all engines. This high-tech assembly shifts the gears extremely quickly and comfortably – in fully automatic or manual mode, controlled by shift paddles on the steering wheel (standard as of 103 kW/ 140 hp), according to the driver's wishes.

In the six-cylinder version, the 2.0 TFSI and the diesel engines, the S tronic system is equipped with six gears, as before. The 1.6, the 1.4 TFSI and the 1.8 TFSI engines operate with a newly developed seven-speed S tronic transmission. Their two clutches have no separate oil supply – another innovative solution which increases the already high efficiency still further. Six of the seven gears are short and sporty, whereas the seventh reduces the engine's speed and consumption thanks to its long gear ratio.

Audi has also extended the quattro range – a unique feature in the premium compact class. The four-wheel-drive system is now available for five engines – the 1.8 TFSI, the 2.0 TFSI, the 3.2 (standard) and the two 2.0 TDI engines. The central, hydraulic multi-plate clutch had been intensively further developed – it now responds even faster when the engine's power has to be redistributed between the axles. This high level of effort results in a further increase in stability, traction and driving enjoyment.

Precision and harmony: The dynamic chassis

The standard dynamic chassis also blends safety, sportiness and comfort, imparting direct precision and a harmonious character. The four-link rear suspension and the extremely efficient electromechanical power steering are complex technologies. Optional sports suspension (standard in Ambition) lowers the body by 15 millimeters (0.59 inches). The optional windshield with acoustic glazing (standard in Ambiente) additionally ensures greater comfort and better acoustics.

On winding roads, the Audi A3 and the Audi A3 Sportback are able to outpace their rivals with an optional high-tech feature – the adaptive shock absorber control system, Audi magnetic ride. The driver can switch between "Normal" and "Sport" programs. A magneto-rheological fluid, which circulates in the shock absorbers, changes its flow characteristics within milliseconds when a voltage is applied; the damping system's characteristics switch – from comfortable to sporty. The electronic control system is available from Audi for the gasoline engines as of 118 kW (160 hp) and both of the two-liter TDI engines.

A question of character: The equipment lines

The Audi A3 and the A3 Sportback have also been significantly upgraded in equipment terms. Three lines are available. Attraction – with the "chorus" radio system, including four speakers – is a variant which is full of character. The dynamic Ambition line is fitted with features such as sports seats, sports suspension and 17-inch wheels, whilst the luxurious Ambiente is equipped with a light and rain sensor, a cruise control system, an interior light package and a new windshield with acoustic glazing as standard, besides other features.

The S line, which contains an exterior package and a sports package, the luxurious Audi exclusive line and the refined options from the Audi exclusive range are optionally available for pronounced individualists.

In the infotainment sector, customers can choose between cutting-edge solutions, from two navigation systems to the Bose sound system and the iPod connection (from quattro GmbH's Audi exclusive range). Many extras document the high technological standard of the A3 model series, including the two-zone deluxe automatic air conditioning system and adaptive light, the dynamic cornering light system.

The Park Assist system is a brand-new high-tech system. At low vehicle speeds (up to 30 km/h (18.64 mph)), its ultrasonic sensors measure longitudinal parking spaces at the side of the road. If one of these is sufficiently large to reverse the vehicle in, the driver is provided with an indication in the driver information system. If he now engages reverse gear and accelerates, the system takes over the electromechanical steering and automatically steers the car into the parking space. The driver only has to operate the accelerator, the clutch and the brake.

Pure power: The new S3 Sportback

New features are also available at the dynamic pinnacle of the model line: The three-door Audi S3 has been joined by the Audi S3 Sportback. It is fitted with the same engine, a 2.0 TFSI with an output of 195 kW (265 hp) and 350 Nm (258.15 lb-ft) of torque, which is available from 2500 to 5000 rpm. The direct injection two-liter turbo engine accelerates the five-door vehicle to 100 km/h (62.14 mph) in 5.8 seconds, up to its governed top speed of 250 km/h (155.34 mph). The engine consumes an average of just 8.5 liters of fuel per 100 km (27.67 mpg) – further proof of Audi's successful efficiency strategy. A six-speed manual transmission transmits the power to a quattro powertrain as standard.

The sports suspension integrates a range of lightweight aluminum components, and lowers the body by 25 millimeters (0.98 inches). Black brake calipers grip impressive 17-inch disk brakes. The S3 Sportback and the S3 respond to all requirements with the lightning-fast reflexes of a trained athlete.

It reacts spontaneously to steering movements and remains stable, precise and almost entirely neutral at the handling limits. On exiting curves, its four driven 18-inch wheels regain traction very quickly – ensuring that vital advantage.

Like the A3, the S3 has also been optically modified. It is distinguished from its mass-produced brothers by a range of sharp lines – on the single-frame grille, the skirts and the roof spoiler, for example. In the interior, sports seats with fabric and leather seat covers provide the driver and passenger with firm hold. The Audi exclusive range offers bucket seats (folding for the three-door S3). Inlays in piano finish black, a black or silver roof lining and aluminum pedals accentuate the fine sports ambience. Automatic air conditioning, an anti-theft alarm system and xenon plus headlamps with LED daytime running lights round off the standard equipment.

Sales of the new-look Audi A3, A3 Sportback and the two S3 variants will be getting off to a start in the next few days, with delivery scheduled to commence in the summer. With only marginally adjusted prices, this means a much improved A3 at an attractive starting price of €20,350.

Exterior design

An expressive exterior design and lines which surge forwards – the athletic exterior of the Audi A3 and the A3 Sportback has been further streamlined. The new features at the front end are the most eye-catching. The single-frame radiator grille has been fitted with a new trim grille and a redeveloped chrome frame, further emphasizing its striking character. The bumper and the air inlets – with integrated fog lamps in the sporty Ambition equipment line – have also been redesigned. Modifications to the engine hood and the fenders cause the front end to appear more clearly defined and wider.

With their confident look, the headlamps express the entire philosophy with which Audi develops its models – they are small, technical works of art of the very highest precision. The integrated, vapor-deposited chrome trim, the "wing", has already advanced to become a typical feature of the brand, as has the innovative safety system of the daytime running lights. Depending on the design of the headlamps, both components reveal slight differences.

In the high-powered H7 halogen headlamps, long-life bulbs are employed in the lower area for the daytime running lights. Each of the optional xenon plus headlamps, which can be further refined with adaptive light, the dynamic cornering light system, are fitted with seven light-emitting diodes located at the upper edge of the headlamps.

Further new details accentuate the coupe-like side view of the A3 and the A3 Sportback. The exterior mirrors are equipped with integrated turn signal indicators and the door handles have been redesigned. Powerful 16-inch wheels fill out the wheel housings; the wheels fitted in the Ambition line have a diameter of 17 inches and are manufactured from cast aluminum. The Audi exclusive range available from quattro GmbH also offers extremely sporty 18-inch wheels in four different designs.

The rear view of both models has now also become more expressive. The wide lamps, which are drawn into the trunk lid from the side panels, emphasize the horizontals. Plastic rods, which are supplied by LEDs, form flat light coronas in the A3 Sportback during the hours of darkness; these light guide rods additionally generate a particularly homogeneous and precise light profile. In the three-door A3, the trunk lid has been provided with a new light edge. Modifications to the bumper further enhance the end of the vehicle. Engines as of an output of 77 kW (105 hp) are equipped with an exhaust system with twin tailpipes.

Moderate: Increase in length

Due to the design changes, the length of both A3 variants has increased. The length of the three-door version has increased by 25 millimeters (0.98 inches) to 4.24 meters (13.91 feet), with six millimeters (0.24 inches) being added to the five-door Sportback (4.29 meters (14.07 feet)). The vehicle's sporty proportions therefore remain virtually unchanged. The width of 1.77 meters (5.81 feet) and the height (1.42 meters (4.66 feet)) remain unchanged; the drag coefficient is 0.33. Four new colors make the color charts even more attractive – Aruba Blue, pearl effect; Glass Blue, pearl effect; Condor Gray, metallic; Meteor Gray, pearl effect. A total of 14 (3-door A3) or 15 (A3 Sportback) paint finishes are available.

Customers who value an even sportier look can order the S line exterior package, which offers identical components for the A3 and the A3 Sportback. At the front, the package provides specially designed grille inserts, bars, fog lamp surrounds in chrome-look and the bumper. A roof spoiler and tailpipe trims for the four-cylinder vehicles catch the eye at the rear, with door sill strips and lettering at the sides.

Interior

The interior of the A3 model series treats occupants with its generous amount of space throughout. On the rear bench seat, the Sportback actually offers a full 903 millimeters (35.55 inches) of leg room, therefore setting standards in the premium compact class. Like the three-door A3, it has a long wheelbase of 2.58 meters (8.46 feet).

The fascinating atmosphere of sporty elegance is also typical of Audi. The basic characteristics of the exterior design are reflected in the interior – clear lines encompass generous surfaces, all elements are harmoniously coordinated. These high esthetic qualities are combined with ergonomically perfect styling. Fine materials and an uncompromisingly high-quality finish create an intensive experience of precision and quality.

The cockpit: With the look of a sports car

The high, wide center console dominates the cockpit; as in a sports car, it is joined to the transmission tunnel via two struts. A sporty dome arches over the instrument cluster. The four round air vents – refined with discreet chrome inserts, as is the light switch – call the TT Roadster to mind. The switches and the air conditioning controls on the center console are presented in a new, elegantly rounded design. An optional light package lends the interior further splendor.

The topic of ergonomics is always one of the primary concerns in Audi's specifications catalog; it has been implemented to perfection in the A3 and A3 Sportback. Numerous storage compartments are available; a special package includes nets on the front seat backrests and on the tunnel, a stowage compartment beneath the driver's seat and a net beneath the rear shelf. This package is fitted as standard in the Ambiente line, and is available as an option in the other equipment lines.

In the instrument cluster, red pointers move over redesigned, sporty, black dial faces. Located between the speedometer and the tachometer, two smaller gauges indicate the coolant temperature and the fuel tank capacity. The Ambition and Ambiente lines are equipped with the driver information system as standard. Its display provides important information in brilliant white lettering. Within this, the gear change display indicates the ideal gear as a recommendation for efficient driving. The logic implemented in the optional navigation system and the navigation system plus, which includes a DVD drive and a 6.5-inch color display, follows the intuitive operating logic of the MMI concept fitted in the large Audi model lines.

The steering wheel in the Audi A3 and A3 Sportback can be adjusted axially and vertically; the Ambition line is equipped with a three-spoke leather-covered sports steering wheel with discreet aluminum trim strips. Multifunction buttons are also available for the audio and navigation systems; when the S tronic transmission is fitted, these are joined by shift paddles (standard as of 140 hp). Audi also offers various three-spoke steering wheels for the Ambition line; as in a racing car, the rims of these are flattened at the bottom.

Precisely as desired: Seats

A wide range of options is also available for the seats. In the Attraction line, the driver's seat can be adjusted vertically; this is joined by the passenger seat in the other two lines. In the Ambition, both front seats offer sporty styling, whilst a center armrest provides additional comfort in the Ambiente. An electric four-way lumbar support, heating for the front seats or also for the two outer rear seats plus electric seat adjustment (option for A3 Sportback) are available for particularly demanding customers.

The standard seats are covered with cloth. Depending on the line, these are available in different designs and colors, and are named Frequency, Dynamic and Meridian. Vienna leather is also available as an alternative. Audi offers a wide range of leather grades for the sports seats – Vienna leather, Fine Nappa leather and a combination of Alcantara and leather. The leather range encompasses a total of six colors, including the two new colors mineral gray and mustang brown.

Audi's interior designers have perfectly coordinated the seat designs to the colors of the cockpit and the shades of the carpets and door linings. Depending on equipment line, new standard inlay variants named pearlescent, micrometallic and vavona wood are available. Aluminium Medial finish silver or Walnut brown inlays are also available as options.

The S line sports package lends the interior a particularly cool touch. The interior is designed in black, whilst the seams of the seat upholstery, the floor mats and the steering wheel are either silver or black. The covers are available in three versions – cloth/leather, Alcantara/leather or Vienna leather. The sports steering wheel, the door sill strips and the trim inserts – in aluminum or piano finish black – are specifically differentiated.

The products available from quattro GmbH's Audi exclusive range – whose highlights include bicolor-look seat upholstery in three colors – offer even greater individuality. The optional extras available from Audi exclusive also include highlights such as optional paint finishes or a style package in black.

Practical quality: Large luggage compartment volume

With a load-through width of one meter (3.28 feet) and a volume of 350 to 1,080 liters (12.36 to 38.14 cubic feet), the Audi A3 offers the largest luggage compartment in its class, with the A3 Sportback topping this at 370 to 1,100 liters (13.07 to 38.85 cubic feet). These values are a few liters lower in the variants with quattro drive due to the special rear axle.

A load-through aperture – with an armrest and cup holders or also with a ski bag – is optionally available. The rear seat backrests in all models can be split 1/3:2/3 as standard; they can be released and folded down effortlessly. The extended luggage compartment in the three-door version has a length of 1.52 meters (4.99 feet), that of the Sportback 1.54 meters (5.05 feet). Bag hooks and lashing points are fitted as standard; instead of the tire repair set, Audi supplies a compact spare tire free of charge if desired.

A luggage compartment package, which includes a versatile safety net and a 12 V socket, is optionally available for all versions of the A3 and the A3 Sportback; Audi also offers a reversible mat. A particularly clever feature is optionally available for the front-wheel drive versions – a reversible load floor. Depending on its position, it can be used either as a level floor or as a drip tray for damp objects; when removed from the luggage compartment, it can also be used as a tray. Roof rails and a panoramic sunroof are also available for the Audi A3 Sportback leisure vehicle.

Powertrain

The Audi A3 and the A3 Sportback will be launched with eight powerful and efficient engines, six of which are state-of-the-art four-cylinder direct injection engines with turbocharging. Their abbreviations, TFSI and TDI, stand for the strengths of Audi engine technology – for performance and tractive power, for dynamics, smooth running characteristics and efficiency.

The range of power transmissions has been further expanded and is therefore even more attractive: Five of the eight engines leave the assembly line with standard six-speed transmissions. The high-tech S tronic transmission is available for all variants, in a new seven-speed version for certain variants. The quattro four-wheel drive system is available – in a further improved evolutionary stage – for five engines.

The five gasoline engines cover a wide range in terms of output. The entry-level assembly is the tried-and-tested 1.6-liter engine with aluminum crankcase and variable intake manifold. It has an output of 75 kW (102 hp) and offers 148 Nm (109.16 lb-ft) of torque at 3,800 rpm. This refined short-stroke engine actuates its valves with low friction via roller rocker fingers; a range of other components have been frictionally optimized to achieve low fuel consumption.

Agile performance: Result of lightweight design

In combination with the new seven-speed S tronic transmission, the three-door A3 sprints to 100 km/h (62.14 mph) in 11.7 seconds, continuing up to its top speed of 185 km/h (114.95 mph). This agile performance is also thanks to its low weight of just 1220 kg (2689.64 lb) – consistent lightweight design is one of the major strengths of the entire model range. The A3 1.6 consumes an average of 6.7 liters of fuel per 100 km (35.11 mpg). It is fitted with a five-speed manual transmission as standard, and is driven via the front wheels.

At the other end of the gasoline engine range is the V6 with a displacement of 3189 cm3. It offers maximum torque of 320 Nm (236.02 lb-ft), which is available between 2,500 and 3,000 rpm, and output of 184 kW (250 hp). The particular characteristic of this long-stroke engine is its extremely low cylinder angle of just 15 degrees – enabling it to be fitted with two camshafts. Both can be continuously adjusted, by 52 degrees on the intake side and 42 degrees on the exhaust side.

The 3.2-liter V6 is a high-torque, sonorous and free-revving engine. It accelerates the A3 from 0 to 100 km/h (62.14 mph) in 6.1 seconds. Its top speed is 250 km/h (155.34 mph) (governed), with average consumption of 9.4 liters per 100 km (25.02 mpg). The V6 is always coupled to the six-speed S tronic and quattro four-wheel drive.

TFSI: Superior engine technology

The three medium-sized gasoline engines in the A3 and in the A3 Sportback are four-cylinder TFSI engines – with which Audi is again demonstrating its leading position in engine construction. They ideally combine the superior technology of FSI gasoline direct injection with charging via a turbocharger.

In direct injection, the fuel is injected directly into the combustion chambers at high pressure; valves in the intake tract specifically cause it to swirl together with the air blown in by the turbocharger. Fuel evaporation lowers the temperatures, solving the old, basic problem of all turbocharged engines – high heat development and the tendency to knock. Despite charging, the engineers have succeeded in providing these engines with high compression, making a vital contribution towards highly efficient combustion.

The smallest TFSI engine is a perfect example of another of Audi's successful efficiency strategies – downsizing, which replaces displacement via charging. This short-stroke engine has a displacement of just 1,390 cm3, but offers an impressive torque of 200 Nm (147.51 lb-ft), which is additionally available over a wide engine speed range from 1,500 to 4,000 rpm. 80 percent of this torque are practically available as of idle speed, at 1,250 rpm – a top value in this class. The 1.4 TFSI also sets standards with its smooth running and pleasant sound profile.

The small four-cylinder engine, which always drives the front wheels, offers impressively agile performance, particularly when the vehicle is fitted with the seven-speed S tronic instead of the six-speed manual transmission. With this, the three-door Audi A3 1.4 TFSI sprints from 0 to 100 km/h (62.14 mph) in just 9.3 seconds, continuing up to 203 km/h (126.14 mph). However, its average consumption is a mere 5.6 liters/100 km – the equivalent of only 133 grams of CO2 per kilometer (214.04 g/mile).

The next largest turbocharged gasoline engine, the 1.8 TFSI, also combines all of the features of cutting-edge engine technology. It is very light, weighing just 135 kg (297.62 lb). One intake camshaft, which can be adjusted by a crank angle of 60 degrees, improves combustion chamber filling; two balancer shafts compensate the second-order inertia forces, thereby ensuring highly cultivated running. With its volumetric flow regulation and two-stage pressure control, the oil pump reduces fuel consumption by 0.2 liters per 100 km. Complex fine-tuning on the pistons, the cylinder bores and the crankshaft bearings reduces internal friction.

The water-cooled turbocharger is designed for a spontaneous response – at an engine speed of 2,000 rpm, the engine only requires 1.2 seconds to offer its maximum torque. The four-cylinder engine is spontaneous, fleet-footed, free-revving and high-torque. From its displacement of 1,798 cm3, it generates a similar amount of power as a naturally aspirated V6 engine a few years ago: It offers an output of 118 kW (160 hp), with a high maximum torque of 250 Nm (184.39 lb-ft) from 1,500 to 4,200 rpm.

Its performance is accordingly superior: 0 – 100 km/h (62.14 mph) in 7.5 seconds, top speed of 220 km/h (136.70 mph) – with an average consumption of just 6.6 liters/100 km (35.64 mpg). These values apply to the three-door vehicle with front-wheel drive and seven-speed S tronic. A six-speed manual transmission is fitted as standard. The A3 1.8 TFSI can also be optionally fitted with quattro drive.

Subscription to victory: The 2.0 TFSI

The most powerful four-cylinder engine fitted in the A3 family is the 2.0 TFSI. Technically related to the 1.8 TFSI, it is a particularly successful model: Since 2005, an international jury comprised of journalists has voted it "Engine of the Year" four years in a row. The two-liter engine also operates with an adjustable intake camshaft and two balancer shafts. Audi has given it a high compression of 10.5:1, previously reserved for sporty naturally aspirated engines; thanks to this, thermodynamic efficiency is improved still further.

The four-valve engine has a displacement of 1,984 cm3; it combines superior tractive power with high peak output. In the manner of a powerful diesel engine, it transmits 280 Nm (206.52 lb-ft) onto the crankshaft at just 1,700 rpm; this maximum torque is constantly available up to 5,000 rpm. Its output peaks at 147 kW (200 hp).

The 2.0 TFSI engine accomplishes all of its tasks with absolute ease. Together with the six-speed S tronic, which is optionally available in addition to the seven-speed manual transmission, it accelerates the front-wheel-drive three-door A3 to 100 km/h (62.14 mph) in 6.8 seconds, reaching a top speed of 238 km/h (147.88 mph). An average of 7.0 liters of fuel/100 km (33.60 mpg) suffices. Optionally, the A3 2.0 TFSI also leaves the assembly line with the high-tech powertrain combination of S tronic and quattro.

TDI: The modern embodiment of sportiness

Audi's TDI engines also set the standards amongst the competition. The brand with the four rings introduced this technology back in 1989, and has been gradually extending its lead ever since. The Audi diesel engines are the modern, smart embodiment of sportiness – the two Le Mans victories celebrated by the R10 TDI racing car in 2006 and 2007 demonstrated the power offered by the TDI engine. In the three four-cylinder engines which Audi fits in the A3 and A3 Sportback, high outputs, high torques, low consumption values and refined running come together to form a rounded overall picture.

The 1.9 TDI is a modern classic – high-torque, powerful and extremely efficient. The two-valve engine with its displacement of 1,896 cm3, which is supplied by a unit injector, has an output of 77 kW (105 hp) and transmits 250 Nm (184.39 lb-ft) of torque onto the crankshaft at just 1,900 rpm. As in the case of all Audi TDI engines, its exhaust gas is cleaned in a particulate filter. The 1.9-liter engine is available in both the conventional variants of the A3 and A3 Sportback and in the particularly economical e models.

It always drives the front wheels; a five-speed transmission is fitted as standard, whilst the six-speed S tronic is available as an option (not in the e model).

The three-door A3 and the A3 Sportback 1.9 TDI e consume just 4.5 liters of diesel per 100 km (52.27 mpg) – corresponding to CO2 output of 119 g/km (191.51 g/mile) and a range of over 1200 km (745.65 miles) with one tank of fuel.

In the e models, the engine electronics are specifically and extensively coordinated to achieve low consumption. A longer gear ratio for gears three to five, rolling resistance-optimized tires and specific fine-tuning measures on the body help to achieve this high efficiency. Typically of Audi, driving pleasure does not suffer as a result – quite the opposite: With a top speed of 194 km/h

(120.54 mph), the three-door A3 1.9 TDI e is actually 7 km/h (4.35 mph) faster than the entry-level version. Acceleration from 0 to 100 km/h (62.14 mph) remains the same at 11.4 seconds.

The intensively redeveloped four-cylinder TDI engine, which has a displacement of 1968 cm3, builds on the characteristic strengths – driving pleasure, economy and smooth running characteristics – of its predecessor, the most frequently built diesel engine in the world. The piston geometry has been modified. Two balancer shafts further reduce vibrations. The toothed belt drive has additionally been redeveloped in terms of acoustics. The turbocharger is also of a new generation; it operates with adjustable guide vanes to build up torque rapidly. Electric motors control the position of the swirl flaps in the intake manifold to adapt the inflowing air to the load and engine speed.

Smoother running characteristics: Common rail injection

Important progress has also been achieved in the injection system: A common rail system has replaced the previously implemented unit injectors. The rapidly switching piezo injectors, with their eight-hole nozzles, are able to inject fuel up to five times per working cycle – this precise modulation audibly reduces the noise level. The system pressure of 1,800 bar equates to extremely fine fuel atomization and efficient combustion.

This combined progress leads to a high maximum engine speed of 5,000 rpm and improved thermodynamics in the combustion chambers. These enable the 2.0 TDI to be operated with up to 60 percent recirculated and cooled exhaust gas, significantly reducing untreated nitrogen oxide emissions.

Audi is equipping the A3 model series with two versions of the further developed 2.0 TDI engine, generating 103 kW (140 hp) and 125 kW (170 hp). Both can be combined with three drive variants – front-wheel drive with six-speed manual transmission, front-wheel drive with six-speed S tronic or quattro with manual transmission.

In the 103 kW (140 hp) version, the two-liter engine provides torque of 320 Nm (236.02 lb-ft), which is available from 1,750 to 2,500 rpm. With 8.9 seconds for the standard sprint and a top speed of 207 km/h (128.62 mph) (three-door version with front-wheel drive and S tronic), the diesel engine offers sporty performance. It consumes an average of 5.1 liters of fuel/100 km (46.12 mpg).

In the more powerful version, the 2.0 TDI offers an impressive 350 Nm (258.15 lb-ft) of torque from 1750 to 2500 rpm. The three-door version with front-wheel drive and S tronic reveals dynamic key values of 7.8 seconds for the standard sprint and a top speed of 222 km/h (128.62 mph). In view of this performance, its low standard consumption of just 5.6 liters/100 km (42.00 mpg) is particularly impressive.

High-tech from Audi: Power transmission

Front-wheel or four-wheel drive, manual transmission or S tronic – in the A3 family, Audi offers a range of power transmission systems unlike any other competitor in the premium compact class. The six-speed manual transmissions, which are fitted as standard with all engines except the 1.6, the 1.9 TDI and the 3.2 engines, have particularly light magnesium housings. They can be shifted precisely and smoothly over short distances, and are extremely efficient.

One of the highlights which lends the A3 and the A3 Sportback their exceptional position amongst the competition is the optional S tronic (standard in the 3.2 quattro). Audi's dual-clutch transmission combines the comfort of an automatic transmission with torque converter with the dynamics and efficiency of a manual transmission.

The driver can control it manually via a one-touch lever or with paddles on the steering wheel. Two fully automatic operating modes are additionally available – D for Drive and S for Sport. In N mode, the transmission management system ensures that the engine runs at low speed whenever possible, in order to save fuel.

The extremely compact S tronic is able to change its gears at lightening speed without any interruption in tractive power. The so-called mechatronics – a block consisting of the central processor and the hydraulic actuator complex – control its operation. Two gear train halves are integrated into the S tronic housing; the first consists of the gear set for the odd gears, the second of the gear set for the even gears. The two clutches are positioned in series; they operate two input shafts on a common axle. Clutch 1 is connected to a full shaft, which acts on gear train half 1, clutch 2 to a hollow shaft, which encapsulates the full shaft and operates gear train half 2.

The two gear train halves are permanently active, but only one is frictionally connected to the engine. When, for example, the driver accelerates in third gear, which lies in the first gear train half, the fourth gear is already engaged in the second gear train half. Shifting gears takes place by switching clutches – whilst clutch 1 opens, clutch 2 closes. This process is so smooth and comfortable that the driver barely notices it. It takes only a few hundredths of a second and is carried out with no noticeable interruption in tractive power.

Completely new: S tronic with seven gears

Audi fits two different versions of the S tronic system in the A3 and the A3 Sportback. The familiar six-speed version, which is able to cope with high torques, is installed in the 2.0 TFSI, the 3.2 quattro and the TDI engines. For the 1.6, the 1.4 TFSI and the 1.8 TFSI engines, a newly developed, particularly lightweight seven-speed assembly has been implemented. Unlike the six-speed S tronic, its two clutches are dry. Discontinuation of the oil supply offers progress which further enhances the transmission's already high efficiency.

A further solution helps to attain low fuel consumption: Six of the seven gears are short and sporty, whereas the seventh reduces the engine's speed thanks to its relatively long ratio.

Further technology which is superior to that of the competition, and which Audi offers in the A3 model line, is the quattro four-wheel-drive system. It is optionally available for the four-cylinder TFSI (as of 118 kW/160 hp) and the two 2.0 TDI engines; it is fitted as standard with the six-cylinder 3.2-liter engine. The quattro drive provides the A3 and the A3 Sportback with a vital advantage under all conditions, both in summer and in the winter – the high, additional grip, slip-free acceleration, vehicle dynamics, stability and straight-line stability make the difference.

The core element of the quattro drive is an electronically controlled multi-plate clutch. It is mounted at the end of the propshaft in the rear end – a location which improves the distribution of weight in the vehicle. Under normal driving conditions, the clutch transmits the engine's power to the front wheels; when required – i.e. when the front wheels move onto a slippery surface – it diverts this power continuously to the rear wheels. On switching over, the plates in the interior of the clutch are compressed by means of high oil pressure. A new pressure reservoir for the pump now makes this process even faster – it only takes a few milliseconds.
Dynamic chassis

Sportiness and comfort – the chassis of the Audi A3 and the A3 Sportback offers both. Its high qualities are best experienced on winding, secondary highways. The initial, subjective impression is the result of the precision and ease with which the vehicle follows the steering angle, plus the stability with which it holds the road on fast corners – almost neutrally at the handling limits, with only slight understeer.

The suspension in the A3 and the A3 Sportback responds gently and absorbs impulses from the road surface with composure at any speed. The steering also remains imperturbably calm and always imparts a fine sensation of road contact plus a precise, firm steering feel.

Aluminum subframe: Front suspension

The front suspension, which has a track width of 1,534 millimeters (60.39 inches), follows a tried-and-tested design form – it is a McPherson design with lower wishbones. The subframe to which it is linked consists of lightweight aluminum, which improves load distribution between the front and rear axles.

The electromechanical rack-and-pinion steering with speed-dependent power assistance is characterized by its low energy consumption. As the system does not have to consume any energy when driving straight ahead, it saves an average of 0.2 liters of fuel per 100 kilometers. With its ratio of 16.2:1, the steering is of a sporty, direct design.

Networked with the ESP (Electronic Stabilisation Program) sensors, the steering automatically undertakes minor corrections if the A3 or the A3 Sportback drifts from its straight course, due to crosswinds, for example. A second function intervenes if the vehicle appears likely to start skidding: It inhibits steering corrections on the part of the driver, which would exacerbate the situation, by temporarily reducing power assistance, therefore making the steering "heavier". In contrast, positively impacting corrections are supported with increased servo power.

A further technical highlight in the Audi A3 and A3 Sportback is the four-link rear suspension with a track width of 1,507 mm (59.33 inches). It separately supports the longitudinal and lateral forces, which offers major advantages in practice. The trailing arms absorb the drive and braking forces; their bearings are of a relatively soft design in the interests of ride comfort. In contrast, the three wishbones per wheel are rigidly connected to the axle carrier, benefiting vehicle dynamics.

As on the front axle, the rear axle carrier is rigidly bolted to the body to increase stiffness. All of the links are manufactured from high-strength grades of steel. The shock absorbers and the compact coil springs are separate, enabling a large-volume luggage compartment. Anti-roll bars are fitted on the front and the rear axle.

In the Ambition equipment line, the Audi A3 and the A3 Sportback are factory-fitted with a sports suspension, which lowers the body by 15 mm (0.59 inches); this can also be optionally deselected. It is available as an option in the Attraction and Ambiente lines. quattro GmbH offers an S line sports suspension which lowers the body by a further 10 mm (0.39 inches).

Powerful wheels: Diameters from 16 to 18 inches

The Attraction variants are fitted with 16-inch wheels on which 205/55 tires are mounted as standard. Optional cast aluminum wheels are available with the same tire format as those fitted in the Ambiente line. The Ambition line is equipped with 17-inch wheels with 225/45 tires. Audi additionally offers a range consisting of around nine wheel variants, including four particularly sporty quattro GmbH versions in 18-inch format. A tire pressure monitor is also available as an optional extra.

The brake system harmonizes perfectly with the sporty character of the model series. Its pedal feel is spontaneous and taut, whilst its response can be precisely dosed. The size of the brakes is coordinated to the relevant engines. The ventilated front disks reveal diameters of 280 or 288 and 312 millimeters (11.02 or 11.33 and 12.28 inches), whilst the solid rear disks measure 255 or 286 millimeters (10.04 or 11.26 inches).

When fine-tuning the ESP system, the engineers attached great importance to reducing the braking distance and to both sporty and discreet regulation. The ESP system's functions include dry braking in wet conditions, in which the pads are repeatedly and briefly applied onto the disks. The ESP system can be optionally extended with a starting-off aid called the Audi hill hold system; this is standard in combination with the S tronic transmission. The system continues to maintain the brake pressure for a moment when the driver has released the foot brake. He is therefore able to start off effortlessly uphill without the risk of rolling backwards.

Audi magnetic ride: Dynamics precisely as desired

An impressive high-tech solution is available for the gasoline engines as of 118 kW (160 hp) and both two-liter TDI engines as of 103 kW (140 hp): The electronic shock absorber control system, Audi magnetic ride, solves the conflicting aims of comfort and vehicle dynamics. Once again, the A3 and the A3 Sportback easily leave their rivals standing with this technology.

A synthetic hydrocarbon oil, in which minute magnetic particles with a grain size of just three to ten micrometers (one thousandth of a millimeter) are enclosed, circulates in the shock absorber plungers. Applying voltage to a coil leads to the formation of a magnetic field, in which the alignment of the particles changes. They are positioned transverse to the oil's direction of flow, thereby inhibiting its flow through the plunger ducts. This changes the damping characteristics within a matter of milliseconds.

The system's control unit constantly analyses the status of the road and the driver's style, and adjusts its operating mode adaptively. The driver can switch between normal and sports mode at the push of a button. In the normal setting – with high oil flow – the Audi A3 and A3 Sportback offer a well-balanced, comfortable ride. In sports mode – with low viscosity – they hug the road tightly and closely; rolling motions are consistently suppressed. The steering responds even more precisely, and specific support of the wheels makes the vehicles' self-steering behavior even more neutral.

Equipment

Their equipment also underlines the Audi A3 and the A3 Sportback's character as compact premium vehicles. The extensive range of standard and optional features underpins their outstanding position.

Even in the Attraction line, which is itself full of character, both body variants leave the assembly line with two or four electric windows (3-door A3/A3 Sportback), a stowage compartment beneath the passenger seat and daylight driving lights. An easy-entry function for the front seats (3-door A3), radio remote control for the central locking system, electrically adjustable exterior mirrors with turn signal indicators plus a vertically adjustable driver's seat round off the comfort equipment. The chorus radio system with four speakers is fitted as standard.

The standard range of restraint systems is comprehensive. It encompasses airbags for the driver and passenger, front airbags which protect the chest area and the pelvis plus a curtain airbag system. Added to these are five head restraints, five three-point seat belts – with tensioners and belt force limiters in front – and the integral head restraint system on the front seats. The front bumper and the engine hood are designed to minimize the effect of collisions with pedestrians as far as possible.

For sports fans: The Ambition line

The sporty Ambition line can be clearly recognized even from the exterior – thanks to 17-inch aluminum wheels, fog lamps and a sports suspension. Its interior offers two height-adjustable sports seats. Specially designed sill strips and inlays plus a leather-covered sports steering wheel in 3-spoke design refine the interior. A driver information system, a radio clock and a manual sunscreen for the rear window, which is integrated into the luggage compartment cover, are particularly practical features.

The Ambiente equipment line represents luxury, externally documented by 16-inch aluminum wheels in an elegant 7-arm design. Its interior offers a wealth of equipment – inlays in amber-coloured Vavona wood, a four-spoke leather-covered steering wheel, a storage compartment package, an outside temperature indicator, a cruise control system, a center armrest in front, an interior light package, an interior mirror with automatic anti-dazzle function, a light and rain sensor and a windshield which dampens external noise using a special acoustic film.

Audi offers further equipment lines for pronounced individualists. This involves the S line, which contains an exterior package and a sports package, the luxurious Audi exclusive line and the refined options from the Audi exclusive range.

The regular range of optional extras already includes numerous attractive convenience features. These encompass electrically heated and folding exterior mirrors, a windshield with acoustic glazing, a cruise control system with improved operation, multifunctional steering wheels for operating the telephone, audio and navigation systems, sun blinds and assistance systems for making parking more comfortable: Rear parking aid or front and rear parking aid and the Park Assist system.

The deluxe automatic air conditioning system with sun sensor enables the driver and passenger to control the temperature individually. The options available for the seats are also extensive: A vertically adjustable passenger seat, electric lumbar supports, heating for two or four seats, sports seats and electrically adjustable front seats (A3 Sportback) – no desire is left unfulfilled.

Park Assist system: The A3 steers itself into the parking space

The Park Assist system is a brand new, particularly comfortable high-tech system. It operates using ultrasonic sensors which register longitudinal parking spaces at the side of the road when the vehicle is traveling at speeds below 30 km/h (18.64 mph). If a space is sufficiently large to reverse into, a corresponding indication is provided in the driver information system.

If the driver now engages reverse gear and accelerates, the Park Assist system takes over the electromechanical steering – it automatically steers the A3 and the A3 Sportback into the space in one maneuver. The driver only has to operate the accelerator, the clutch and the brake due to reasons of safety.

In the field of safety, Audi offers an anti-theft alarm system, fog lamps, a tire pressure monitoring system, Isofix anchors for child seats and rear side airbags (in the A3 Sportback). Xenon plus headlamps and the cornering light system, adaptive light, turn night into day.

The A3 also offers many intelligent solutions in terms of practicality. Storage compartment packages are available for the interior and the luggage compartment, plus a load-through aperture with center armrest plus a ski and snowboard bag for the rear bench seat.

A luggage compartment mat and a reversible load floor make the luggage compartment extremely versatile. An electrically driven glass roof is optionally available for the three-door model, whilst the A3 Sportback offers the optional panoramic sunroof – a very large glass roof which enables the interior to be flooded with light. A further option for the Sportback are the roof rails, available in anodized aluminum or in black.

Audi offers a wide selection of multimedia devices for optimal entertainment. The standard chorus CD radio, which comes equipped with four speakers, forms the basis of the range. This continues with the MP3-capable concert radio (six speakers) and the symphony radio with CD changer up to the Bose sound system, whose amplifier contains an integrated digital sound processor. This has an output of 195 W and controls eight or ten speakers (3-door A3/A3 Sportback) via six channels. As of the concert radio, AUX-in jacks on the transmission tunnel are fitted as standard. The Audi exclusive range offers preparation for iPod installation in the glove compartment.

Navigation: The A3 knows the way

The A3 and the A3 Sportback optionally show the driver the way. The smaller solution is a navigation system with a monochromatic 6-inch screen, which reads its data from a CD. The large navigation system plus operates with a DVD player, and is equipped with a 6.5-inch color monitor which optionally shows the route as a 3D image. It contains a radio with dual tuner, slots for reading SD cards and an AUX connection: It can be further upgraded with a speech dialog system. A TV module is also available.

Both navigation devices are located in the center console; their operating logic is oriented towards the highly-praised MMI system fitted in the large Audi model series. For mobile telephony, Audi offers an optional Bluetooth link for the mobile phone plus a hands-free system; this link also supports UMTS-capable mobile phones.

Sale of the new-look Audi A3 and A3 Sportback will be getting off to a start in the next few days, with delivery scheduled to commence in the summer. With only marginally adjusted prices, this means a much improved A3 at an attractive starting price of €20,350.
