2011 BMW Sports Coupe Z4 sDrive35isThe 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.
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. The enhanced engine management system of the BMW Z4 sDrive35is includes an electronically-controlled overboost function to briefly increase torque under full load by another 37 lb-ft. This temporary torque peak of 369 lb-ft gives the car a significant increase in acceleration. The BMW Z4 sDrive35is will complete the sprint from a standstill to 60 mph in just 4.7 seconds (preliminary). Top speed of the BMW Z4 sDrive35is is limited electronically to 250 km/h or 155 mph.

The BMW Z4 sDrive35is includes new M Sport upgrades such as M Aerodynamics and adaptive M Suspension. The adaptive M Suspension combines a ride-height reduction of 10 millimeters (almost 0.4″) with electronically controlled shock absorbers (Dynamic Damping Control) to improve the vehicle’s agility without compromising ride comfort. Special 18-inch light-alloy wheels in five-spoke design round off the sporty character of the Z4 sDrive35is. 19-inch light-alloy wheels are available as an option.

2011 BMW Sports Coupe Z4 sDrive35isThe BMW Z4 sDrive35is offers outstanding power and performance without an increase in fuel consumption or emissions. Its figures are expected to match those of the BMW Z4 sDrive35i with Double-Clutch Transmission on the EPA test cycle. This balance of performance and fuel efficiency results from the fundamental design and layout of the BMW inline-6, which combines twin turbochargers with High Precision direct injection. The fuel injectors operate at a pressure of up to 200 bar (2900 psi), distributing fuel in a conical spray pattern throughout the combustion chamber. Another advantage of direct fuel injection is its cooling effect which allows higher compression while reducing the possibility of detonation. Further technologies offered under the BMW EfficientDynamics philosophy include Brake Energy Regeneration, Electric Power Steering, and on-demand operation of engine accessory units.

2011 BMW Sports Coupe Z4 sDrive35isThe exhaust system of the BMW Z4 sDrive35is has been tuned specifically for this model. Acoustic engineering gives the car a very unique sound pattern across the speed range. This tuned sound is the result of special baffles and a unique set of mufflers. The sound is characterized by a deep rumble with a focus on the low frequency sound range.
