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.

Cyclists urged to make themselves visible

CYCLISTS have been warned to take precautions to make themselves easier to see, in time for the darker evenings of winter time. The clocks are set to wind back by an hour this Sunday, bringing darkness down on homeward commutes and making collisions involving cyclists statistically more likely. A survey of 1,000 cyclists, carried out by Autoglass, found that 48% had been caught without lights or high-visibility clothing when the clocks go back.
