that engine has already won an award, in fact it was last year. In this category:

With seven awards for four engines, BMW once again emerges as the most successful brand from the “International Engine of the Year Awards 2007”, the world’s most important engine competition. For the third time in a row, the Awards jury – consisting of 62 high-ranking international automobile journalists from 30 countries including Australia – awarded the principal prize, the highly sought-after “International Engine of the Year” to the Bavarian automobile manufacturer.

Over the last nine years, BMW has won over 30 of the highly sought-after “International Engine of the Year Award” trophies. This is impressive evidence of the BMW’s market leadership in the field of engine construction.

Best New Engine of 2007

Having already introduced twin-turbos to great acclaim on the 3-litre diesel found in the 335d, 535d and X3, BMW has now developed the technology for petrol power. And the 62 judges from 30 countries decided that the finest powertrain introduced in the past 12 months was the 2,979cc twin-turbo engine that made its debut in the BMW 335i.

The light alloy six’s use of two smaller turbos – each supplying three cylinders with air – rather than a single unit ensures a faster response to changes in throttle position all the way to the 7,000rpm red line, and also seeks to eliminate lag.

The breakthrough engine shows for the first time BMW’s all-new, high- precision direct-injection system. This development maximises performance and fuel efficiency by its precise dosing of the air-fuel mix being fed. The piezo-injectors are located centrally in the combustion chamber between the inlet and exhaust valves. Direct-injection also aids combustion chamber cooling, allowing a higher compression ratio (10.2:1) to be employed to reduce consumption still further.

BMW is proud of the fact that compared with eight-cylinder engines of similar performance – 302bhp peak power, and 400Nm between 1,300rpm and 5,000rpm – the straight-six weighs 70kg less, contributing to a fuel consumption figure of 9.5L/100km (29.7mpg) on the EU combined cycle. Economy does not come at the expense of performance, however: in the 335i Coupé, 100km/h (62mph) is reached from a standstill in 5.5 seconds.

The technology-packed powerplant, which signalled BMW’s return to turbocharged petrol engines after a long absence, has drawn praise from judges around the world. Commented freelancer Paul Horrell: “The engine is unique in its combination of low-rev torque with high-rev exhilaration. And it’s lighter and more fuel-efficient than the big-cube V8 that’s probably the only other way to get the same job done.” Across the Atlantic, Chris Walton of Edmunds.com was as enthusiastic: “Combining direct injection and turbocharging will be fundamental to a new era in power production and economy. Others have done it, but none has exploited this combination to such perfection.”

According to Harald Unger of BMW engine development, the new direct- injection system on the engine is a major step forward. “Since the injector and spark plug are close together in terms of distance and timing, there are big advantages compared with first- generation lean-burning engines, where the fuel cloud was first sprayed against the piston and then to the spark plug.”

Elsewhere in the engine, materials technology plays its part in the form of lightweight camshafts, and turbine blades that are made of a special heat-resistant steel to withstand temperatures of up to 1,050°C.
