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.

Jets land on Rodeo Drive

Tail fins will be all over Rodeo Drive on Father's Day, June 16. The Rodeo Drive Committee has chosen “The Jet Age” as its theme for this year's street-closing concours, with tail-finned cars of the '50s and '60s lined up on the 300 block of the famous street. And to top it off, and perhaps because they made a nice contribution, parked on the 200 block will be a mock-up of the new Lear 85 business jet in all its carbon-fiber glory -- with the tail fin but minus the wings.
