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.

Details are still a bit limited – and we don’t have any info yet on what Gemballa has done with the oily bits – but we do have the picture you see here, which shows the cosmetic stuff.

F1: Back in the U.S.A. 2012

The F1 Grand Prix Circus returns to the USA in 2012 The Americans have never really fallen in love with Formula One in the way the rest of the world – and particularly the Europeans – have. They have plenty of race series of their own, many arguably more exciting. Which you would think would be a good enough reason not to worry too much about the lack of a US Grand Prix on the calendar since the last one in Indianapolis in 2007.
