Eight places to be this Memorial Day weekend, an AW list

Most people spend Memorial Day Weekend in the backyard, at a local beach or stuck in traffic. That's all well and good, but you, AutoWeek reader, are not most people. Where you should be this weekend: 1.

BMW M750d & M650d on the way

BMW M650d & M750d on the way BMW are planning to offer the new tri-turbo diesel from the new M550d in the 6 Series and new 7 Series. Paris launch likely. The BMW M Division range of cars – the power of ‘M’ with the frugality of diesel – officially arrived at this year’s Geneva Motor Show, offering performance almost on a par with BMW’s M cars but with the joy of frugality when you aren’t in the mood to drive like your hair’s on fire.

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.
