Woodcliff Lake, NJ - December 12, 2009, 6pm EST... Combining classic proportions with modern features, the BMW Z4 Roadster enjoys the top spot in its market segment. Now, the new BMW Z4 sDrive35is distills the Roadster's performance potential to produce one of BMW's fastest and best-handling Roadsters ever. The BMW Z4 sDrive35is is making its world debut as a 2011 model at the 2010 North American International Auto Show (NAIAS) in Detroit. It arrives at authorized BMW Centers in Spring 2010.

More air, boost, and torque: More BMW performance.

The latest Z4 model is characterized by instantaneous response to the accelerator pedal, fantastic sounds, and a free-revving spirit. The engine features increased air intake flow and increased boost pressure to release more power with the same standard of efficiency. The combination of twin low-mass turbochargers and High Precision direct injection offers an output a naturally-aspirated engine would only be able to provide through more cylinders and larger displacement.

The turbocharger system developed for the engine of the new BMW Z4 sDrive35is maintains a high output throughout the entire engine speed range. Nominal peak torque is increased to 332 lb-ft from 1,500 rpm to 4,500 rpm. Maximum output of 335 hp is delivered at 5,900 rpm.
