The BMW Z4 sDrive35is is making its world debut as a 2011 model at the 2010 North American International Auto Show (NAIAS) in Detroit. 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.
The sum of all parts.High Precision Injection and Twin Turbo in the BMW Z4 Roadster.Two milligrams of petrol - that's how precise the High Precision Injection (HPI) controls the fuel-air mix. The dosage of the fuel injected is precisely ensured by the piezo injectors with only part of the combustion chamber being filled under lower partial loads. Thanks to the Twin Turbo, it is now possible for the straight six-cylinder engine to provide a supreme standard of power and performance previously only conceivable with far larger engines. Engine weight is also much lower, inter alia on account of the all-aluminium crankcase, which naturally benefits the agility of the entire car and offers more power on less fuel.
The wind is on your side.Aerodynamics on the BMW Z4 Roadster.The two-part hardtop makes it possible to combine a unique roadster experience with outstanding aerodynamics. A comprehensive and sophisticated concept that takes even the smallest detail into account and ensures that all components, from the air intake valves to the boot door, work in harmony to reduce air resistance and thus fuel consumption - especially at high speeds. Make the wind work for you and not against you
Sports seats for the BMW Z4 Roadster.Ergonomic and aesthetic: the optional sports seats were developed for drivers with performance on their minds. Integrated air cushions adjust the backrest width to optimally suit your body and driving style. And at the touch of a button, you can adjust the optional four-way lumber supports so that the horizontal and vertical air cushions provide the perfect contact surface between the seat and your back - contact that allows you to experience true roadster driving in pure comfort.
