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.

And we were almost certain that the SLS Roadster would finally arrive at the New York Motor Show last month after we published photos of an undisguised SLS Roadster out partying in Hamburg.
