BMW Z4 sDrive 35is (2009) at Detroit motor show 2010

These are the first official pictures of the new high-performance BMW Z4 sDrive 35is, unveiled today at the Detroit motor show. A bit of a mouthful (that's BMW's new nomenclature for you), but it's essentially the fastest, hardest Z4 to date since the recently departed M roadster curled over and died.The Z4 sDrive 35is uses Munich's existing 3.0-litre twin-turbo straight six, tweaked to produce 335bhp and 332lb ft of the twisty stuff all the way from 1400-4500rpm. That's one flat torque curve, and a 29bhp jump over the regular sDrive35i.

Check out the 1,360-hp heart of the Koenigsegg One:1

The wild Koenigsegg One:1 showed up on our radars late last year before it appeared at the Geneva motor show in March. The latest piece of machinery from company founder--and Michael-Chiklis lookalike--Christian von Koenigsegg delivers one horsepower per kilogram, hence the name. That means 1,360 hp and 737 lb-ft of torque with a 3,000-pound curb weight.

Ford is developing a virtual child to improve safety research

Researchers at Ford have started constructing a "virtual" six-year-old child that will help them research future safety devices. It will take years to build the complex, multilayer digital dummy, Ford said on Thursday. And the finished computer model won't be used for vehicle validation or crash testing.
