Stuttgart, Jan 04, 2007
The Mercedes-Benz S-Class 4MATIC range impresses with its wide variety and its ability to meet the most diverse customer requirements. Four different engines and two body variants with a long and a short wheelbase are available. At the top of the range, the S 500 4MATIC has a 5.5-litre V8 engine which develops 285 kW/ 388 hp and thus offers an increase in performance of more than 26 percent compared with the previous eight-cylinder powerplant. Its torque figure of 530 Newton metres is also significantly higher (by some 15 percent) than the peak value attained by its predecessor. Maximum torque is available from 2800 rpm and remains constant across a wide engine speed range up to 4800 rpm, for excellent acceleration and mid-range power:

• The new S 500 4MATIC accelerates from 0 to 100 km/h in 5.4 seconds, the same time as that taken by the S 500 with rear-wheel drive. Compared with the predecessor model, the Saloon is more than a second faster.
• In third gear, the S 500 4MATIC accelerates from 60 to 120 km/h in just 5.6 seconds.
• The top speed is 250 km/h (electronically governed).

The eight-cylinder powerplant in the S 500 4MATIC is the top drive unit in the new generation of Mercedes-Benz V-engines which was successfully introduced in mid-2004. Equipped with four valves per cylinder, infinitely adjustable intake and exhaust camshafts, a two-stage intake module and tumble flaps in the intake ducts, the V8 is among the engines with the highest power output and torque in its displacement class. Other technical highlights of this eight-cylinder engine include special shifting camshafts. These reduce the inherent pressure fluctuations in the exhaust train and thereby considerably improve the engine's gas cycle. This makes itself felt among other things by smoother running and higher torque in the lower and medium engine speed ranges. The Mercedes V8 employs the latest lightweight construction principles, with an aluminium crankcase, low-friction cylinder liners of aluminium/silicon alloy, a forged steel crankshaft and weight-optimised connecting rods.
Fuel consumption up by just 0.4 litres compared with S 500
The fact that the combined NEDC fuel consumption of 12.1 to 12.3 litres per 100 km returned by the S 500 4MATIC represents a saving of almost one litre compared with the predecessor model – despite the new unit's higher power and torque – clearly demonstrates the efficiency of the up-to-date design and high-tech features of the new Mercedes eight-cylinder engine. Furthermore, the newly developed all-wheel drive system also has a positive impact. Optimised for weight and friction characteristics, it results in only a slight increase in fuel consumption – just 0.4 litres – compared with the two-wheel drive version of the S 500 (11.7 to 11.9 litres per 100 km).

S 450 4MATIC – second V8 model with 250 kW/340 hp
The second V8 model is the new S 450 4MATIC which is now also available as a rear-wheel-drive model. Its engine technology is closely related to that of the 5.5-litre eight-cylinder unit and includes four valves per cylinder, infinitely adjustable shifting intake and exhaust camshafts, a two-stage intake module, tumble flaps in the intake ducts, an aluminium crankcase, low-friction cylinder liners, a forged steel crankshaft and weight-optimised connecting rods. With a displacement of 4663 cc, it develops a peak output of 250 kW/340 hp and its maximum torque of 460 Newton metres is available across a wide engine speed range from 2700 to 5000 rpm. The 0 to 100 km/h acceleration time of 5.9 seconds puts the S 450 4MATIC on a par with its rear-wheel-drive counterpart. The top speed is 250 km/h (electronically governed). At 11.6 to 11.8 litres per 100 kilometres, its fuel consumption is only 0.4 litres higher than that of the "normal" S 450. This is analogous to the difference in fuel consumption between the corresponding S 500 models.

Premiere for S-Class with diesel engine and all-wheel drive
The third S-Class all-wheel drive model – and also the most economical one – is the S 320 CDI 4MATIC. This is the first time that all-wheel drive has been combined with a turbodiesel engine in the top Mercedes-Benz model series. The advanced six-cylinder CDI unit develops 173 kW/235 hp and offers maximum torque of 540 Newton metres which is available between 1600 and 2800 rpm. These impressive figures put the direct-injection diesel among the engines with the highest power output and torque in its displacement class. As the figures suggest, the powerful six-cylinder engine offers extremely respectable performance: with a 0 to 100 km/h acceleration time of 7.8 seconds, the all-wheel drive Saloon performs to the same high standard as its two-wheel drive counterpart; the top speed is 245 km/h; thanks to the favourable NEDC combined fuel consumption figure of between 8.7 and 8.9 litres of diesel per 100 kilometres, operating ranges in excess of 1000 kilometres are possible. Compared with the rear-wheel-drive S 320 CDI, the 4MATIC model consumes only an additional 0.4 litres of diesel fuel per 100 km.

6.7Top speed km/h* 245Powerful six-cylinder diesel engine with high-tech features
A glance at the technical refinements which characterise the 3.0-litre engine explains the impressive performance data. The high-tech features of this compact V6 powerplant include third-generation common rail direct injection. The combination of an injection pressure of up to 1600 bar and particularly fast-acting piezoelectric injectors ensures efficient mixture formation. Further highlights of the 320 CDI engine include electrically controlled intake port shut-off, intake air throttling, a VNT (Variable Nozzle Turbine) turbocharger with electrically adjustable guide vanes and exhaust gas recirculation with a control valve. Like all Mercedes-Benz diesel passenger cars, the S 320 CDI 4MATIC is equipped as standard with a maintenance-free particulate filter system.
7G-TRONIC automatic transmission with Sport program as standard
Power transfer in all S-Class 4MATIC models is handled by the 7G-TRONIC automatic transmission with steering-column DIRECT SELECT gear selector and steering-wheel gearshift buttons. This combination ensures that optimum use can be made of the impressive performance and torque capabilities in every driving situation. Furthermore, the all-wheel drive models have identical gear spacing and ratios, which has a positive effect on the performance and fuel consumption figures.
An all-new development for all S-Class V6 and V8 petrol models is the 7G-TRONIC Sport transmission. The S/C/M button on the centre console can be used to activate the manual "M" driving mode, allowing the seven gears to be shifted using the two steering-wheel shift buttons – downshifts are performed by pulling briefly on the left button while the right button is used for shifting up. In "M" mode, the system's electronics reliably maintain the last gear selected, even at full throttle. It is thus possible to make optimum use of the high pulling power of the V6 and V8 engines. However, fully depressing the accelerator (kickdown mode) causes the transmission to shift down in order to deliver maximum acceleration. 7G-TRONIC Sport reduces shift times by up to 30 percent in manual mode.
PRE-SAFE® as standard, Brake Assist PLUS as an optional extra
The unique PRE-SAFE® occupant protection system also forms part of the standard equipment of the S-Class all-wheel drive models. PRE-SAFE® recognises a potential accident situation in its early stages: if the braking deceleration exceeds a certain level or there is a risk of skidding, the system tightens the front seat belts and moves the front passenger seat backrest into a more upright position as a precaution. If the vehicle is fitted with the optional multicontour seats, air is pumped into the chambers so that they envelop and support the front passenger and other vehicle occupants. The sliding roof is also closed (optional extra).
Available as an option, Brake Assist PLUS (BAS PLUS) uses radar to register vehicles ahead and warns the driver if the distance is too small or if he or she is approaching the vehicle ahead too quickly. If a collision is imminent, the system instantly calculates the ideal braking assistance, which is immediately supplied even if the driver applies the brakes too gently. This makes it possible to reduce substantially the number of rear-end collisions. The combination of the new Brake Assist PLUS and PRE-SAFE® makes it possible to provide a higher level of occupant protection. Mercedes-Benz is the first car manufacturer in the world to offer such a comprehensive safety system as standard, which goes into action as soon as an accident risk is detected.
PRE-SAFE® Brake uses the latest radar technology
For the first time in the S-Class, Mercedes-Benz is complementing this multiple-award-winning anticipatory protection system with the newly developed PRE-SAFE® Brake. This works in combination with Brake Assist PLUS (BAS PLUS), which not only gives the driver visual and audible warnings that he or she is in imminent danger of running into the vehicle ahead, but also automatically calculates the brake pressure required to prevent an accident. This braking assistance is available as soon as the brake pedal is operated. If the driver does not react to the BAS PLUS warnings, the PRE-SAFE® Brake system triggers automatic partial braking if an acute accident risk is detected and decelerates the S-Class with about 40 percent of the maximum braking force. The automatic partial braking, which is in effect a virtual crumple zone, provides the driver with another clear signal of the need to take action. If the driver then immediately applies the brakes, the maximum braking force is available and it may be possible – depending on the situation – to avert the accident at the last moment. If an accident is unavoidable, the PRE-SAFE® Brake system reduces the impact severity and, in turn, the risk of injury to the vehicle occupants. Mercedes-Benz offers BAS PLUS and the PRE-SAFE® Brake system in conjunction with the optional DISTRONIC PLUS proximity control system.
DISTRONIC PLUS: even operates in stop-go traffic
The radar-based DISTRONIC PLUS system works in a speed range from 0 to 200 km/h and makes driving even more comfortable. In stop-go traffic, DISTRONIC PLUS keeps the new S-Class at the right distance from the vehicle ahead, automatically brakes the car to a standstill if necessary and accelerates it back to the pre-programmed speed following intervention by the driver. In this way the assistance system reduces the driver's workload and provides considerable benefits with regard to driver-fitness safety.
The Brake Assist PLUS and DISTRONIC PLUS equipment package also includes a radar-based Parking Assist system. The system provides early warning if there is danger of a collision when manoeuvring backwards and forwards.
Night view assist: infrared technology for greater safety after dark
Night view assist represents another contribution by Mercedes-Benz to reducing the risk of accidents at night. This system uses infrared light, which is invisible to the human eye and therefore does not dazzle oncoming traffic. Two infrared headlamps illuminate the road, significantly extending the driver's range of vision when on low beam. An infrared camera mounted on the inside of the windscreen picks up the reflected image of the road ahead and displays this in the instrument cluster.
Comprehensive and stylish standard equipment and appointments
Many high-tech systems which increase safety and comfort are standard in the S Class 4MATIC models. They include the ADAPTIVE BRAKE system, second-generation PRE-SAFE®, AIRMATIC air suspension with the Adaptive Damping System, 12-way power-adjustable front seats, the COMAND system with a DVD player, the DIRECT SELECT gearshift and automatic climate control.

Great article

My family has been a firm believer in the 4-Matic system. We've had a couple of 4-Matic Station wagons, our current E430 4-Matic and I used to have a W124 300E 4-Matic.

We used to live in snowy northern Michigan where the roads weren't plowed so well and that car never failed me.

Love those W124 shots. Ok and the W221 ones too.

Edit: I just noticed there is a shot of a W126 S-Class! The W126 had a 4Matic option?

M

Speaking of the W126, a local dealer here, acutally the Mitsu dealer where I used to get old car serviced has a 1990 420SEL on their lot for 8.9K, it has only 75K miles on it! A mint of a car really, at least in pics without knowing the history:













This example appears to be in extraordinary shape for a 17 year old car!

1907: World First AWD Passenger Car
Dernburg-Wagen from Daimler Motoren Gesellschaft

• 100 years ago: The “Dernburg-Wagen” features all-wheel-drive and even all-wheel steering
• Highly sophisticated design by Paul Daimler
• Everyday use in the colony of German South-West Africa, today’s Namibia

The first all-wheel-drive car for everyday use was built by Daimler-Motoren-Gesellschaft (DMG) in 1907. The "Dernburg-Wagen", as it was known, even featured all-wheel steering. It is called after the then Secretary of State Bernhard Dernburg who drove many a kilometer in it in Africa the following year.

In fact the all-wheel-drive history of the company began slightly earlier, in 1903, when Paul Daimler laid the foundations for this technology with a first design draft. The first all-wheel-drive vehicle appeared in 1904, and was quickly followed by others. Since then, the watchword has been that all-wheel drive is the best technology when it comes to better traction and safe, assured progress. Over the decades it has been successfully used in all kinds of Mercedes-Benz vehicles, both passenger cars and commercial vehicles, and from vans to heavy-duty trucks. Some of these models, for example the G-Class or the Unimog, have gained a legendary worldwide reputation, and are to be found virtually everywhere on earth. All-wheel drive also scores heavily in day-to-day driving on normal roads, however, as the Mercedes-Benz saloons with 4MATIC demonstrate.

thanks for the link! it's a very interesting article!

*i guess this is what they called evolutionary design 100 years ago

Very interesting read, Siko. Thanks for posting.

I didn't even know about this car. I always thought the first AWD Mercedes was the 1933 500 G4. I learned something new thanks to you.

wow, christian the one you posted is just great! any info on this? (engine, remaining cars, history info)

Thank you Siko. What an interesting vehicle.

Yep, pretty good-looking car.

The history behind it is a bit dark. It was primarily created for the German Army, who found it too expensive. Then, it became a favorite with high-ranking Nazi party members. Adolf Hitler was often driven around in one of these, particularly in Nürnberg and when Germany annexed the Sudetenland (part of the modern-day
