VIDEO: The M-Sports BMW Z4 sDrive35is 340HP on Film

After details and first official photos of the new BMW Z4 sDrive35iS were released on Sunday, the Bavarian automaker has now followed up with a bunch of promotional videos showing off the hardest version of the roadster to date that will make its world premiere at the 2010 Detroit motor show in January.

It might not be an 'M' model, but the Z4 sDrive35is comes equipped with a tweaked version of BMW's 3.0-litre twin-turbo straight six pumping out 340 ponies as well as a 7-speed double clutch transmission and the M Sports Package that includes an adaptive suspension and numerous M-Sports upgrades.
