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.

The Toyota FT-1 concept would make a damn fine new Supra

The Detroit auto show is just getting started, and Toyota has kicked things off with a nice surprise: The racy FT-1 concept. A product of Toyota's Calty Design Research facility, the FT-1 concept shares some of the swoops and vents with the Lexus RC F. But there's a boatload of high-performance styling cues there, too: Take a quick glance and you might spot the front end of a Ferrari Enzo, the profile of the Nissan GT-R, the double-bubble roof of the SRT Viper/any number of Zagato creations and the oversized retractable rear wing of the McLaren P1.

Land Rover Expedition America presses on through the Rocky Mountains

Land Rover Expedition America is more than halfway across the country, three weeks after having departed Asheville, N.C., on their 5,000-mile route through 10 states. The team is traveling all the way across the country in three Land Rover LR4s -- from sea to shining sea if you will -- almost entirely off-road. The Oregon coast is their destination, and the team is following a route based on an off-road motorcycle trailed created by Sam Corero, a famous off-road motorcyclist who charted this trail back in the 1990s.
