Land Rover Defender Harris Tweed (2012) prototype

Here's a curious mix of classic Britishness and modern modifications: a Kahn-tuned Land Rover Defender fitted with a butch bodykit, enormous multispoke wheels and knobbly tyres and - inside -tweed-trimmed bucket seats. It's like a Spitfire wearing a Damien Hurst-penned livery. This is, to give the car its full title, the Kahn Defender Concept 17 Wide Body - Harris Tweed Prototype.

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.
