New BMW M3 and M4 engine secrets laid bare

BMW's M division has lifted the veil of secrecy on the inline six-cylinder engine bound for its upcoming M3 sedan and new-to-the-range M4 coupe and convertible, revealing a potent twin-turbocharged 3.0-liter direct injection gasoline unit that produces an official 424 hp at 7,500 rpm and what officials describe as "significantly more than 369 lb-ft" of torque. The newly developed engine, known under the internal codename S55 B30, shares its 84.0 mm bore and 89.6 mm stroke with BMW's standard turbocharged 3.0-liter in-line six-cylinder direct-injection gasoline mill, the M55 used across the German car maker's lineup, endowing the aluminum block unit with an overall swept volume of 2,979 cc. This represents a sizeable 990 cc reduction on the engine BMW's M division's new unit replaces, the S65.

With that in mind, Renault has given the 2.0 litre Turbo in the Megane Renaultsport 275 Trophy a bit of a tweak to yield 271bhp hoping that will be enough to beat the current 7:58.4s record.

The 2009 Porsche Cayman S - helping to boost Porsche sales [ad#ad-1] We’ve run stories on how well Porsche, and the whole VW/Audi group, is holding up through the current malaise in the car industry. Porsche’s last lot of profit figures were very impressive, but were mainly due to the huge amounts Porsche made on its trading in VW shares. We noted at that time that Porsche reckoned its sales were slow because people were waiting for the new versions of the Boxster and Cayman, and when that happened sales would increase.
