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.

Chrysler/Lancia Ypsilon

To celebrate 25 years of the Lancia Ypsilon, the Fiat is set to launch an all new variant at the 81st Geneva motor show. Based on a stretched Fiat 500 platform, the Ypsilon boasts an extra 300mm between its front and rear wheels, improving rear legroom and allowing for the additional rear doors. Overall, the Ypsilon's exterior has grown by around 60mm in length, but the cars height has dropped by around 20mm.

BMW-Toyota partnership may yield hybrid Z4, new Supra

The BMW-Toyota sports-car lash-up has been reported on for a couple of years now, but new information from a report in the U.K.'s Autocar sheds more light on the future of the BMW Z4 and what this year's Toyota FT-1 concept will ultimately herald. Like the current Z4, its predecessor and the Z3 before it, as well as every generation of Supra, the new platform will feature a front-mounted gasoline engine. From there, things look to be diverging wildly as technology marches forward.
