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.

Mercedes’ AMG division unveils new twin-turbo V8

Those obsessed with torque bemoaned Mercedes’ high-revving 6.2-litre V8 when it was launched in 2005, but just as the world has come to accept the naturally aspirated engine, the company has now unveiled a new twin-turbo 5.5-litre V8. Up to 563bhp – which is the same as the SLS AMG – and 663lb ft, which is much more than the 479lb ft the modern-day Gullwing supercar manages. The engine is an all-new 5.5-litre V8 (5461cc to be exact) with direct-injection technology, an aluminium crankcase and two turbochargers.

Audi A7 Sportback Launched: Price & Models

The Audi A7 Sportback Launches Finally, after much teasing and a little tormenting, Audi did the decent thing and put us out of our misery with the launch of yet another niche filler – the Audi A7 Sportback – at the Museum of Modern Art in Munich last night. Displayed in all its brown-ness, the Audi A7 looks like an oversized A5 Sportback with the nose of the new A8. In the flesh at launch it somehow seems less impressive than the concept A7; more corporate.
