MUNICH - December 15, 2009: The new BMW Z4 sDrive35is features a modified straight-six power unit with BMW Twin Turbo Technology and High Precision Injection, as well as BMW's seven-speed Sport Automatic with double clutch operation and the M Sports Package including the adaptive M Suspension likewise featured as standard. Roadster accelerates from a standstill to 100 km/h (62 mph) in just 4.8 seconds. The BMW Z4 sDrive35is is making its world debut at the 2010 North American International Auto Show (NAIAS) in Detroit. And parallel to the market launch of this roadster in spring 2010, the M Sports Package is being introduced for all further versions of the BMW Z4.

Combining classic proportions with modern sportiness, the new BMW Z4 has reached the top of its market segment almost overnight. And now this charismatic roadster is entering a new dimension in driving dynamics, the new BMW Z4 sDrive35is offering an even higher standard of performance ensured both by the modified straight-six power unit with BMW Twin Turbo Technology and High Precision Injection, on the one hand, and by BMW’s seven-speed Sport Automatic with double clutch operation and the M Sports Package including the adaptive M Suspension likewise featured as standard, on the other. Appropriate optimisation in engine technology increases maximum output of the 3.0-litre power unit to 250 kW/340 hp. Peak torque is 450 Newton-metres/332 lb-ft, increasing briefly with the Overboost function to 500 Newton-metres/369 lb-ft. The outstanding power and performance of the BMW Z4 sDrive35is is expressed in particular by the significant increase in pulling power and muscle to be clearly experienced in all situations. In conjunction with seven-speed Sport Automatic featuring double clutch operation, this new top-of-the-range roadster accelerates from a standstill to 100 km/h (62 mph) in just 4.8 seconds.

At 9.0 litres/100 kilometres (equal to 26.1 mpg US) and 210 grams in the EU test cycle, fuel consumption and CO2 emissions are the same as on the BMW Z4 sDrive35i with Sport Automatic.

The BMW Z4 sDrive35is is making its world debut at the 2010 North American International Auto Show (NAIAS) in Detroit. And parallel to the market launch of this high-performance roadster in spring 2010, the M Sports Package is being introduced for all further versions of the BMW Z4.

More air, more boost, more torque, more driving pleasure.
The twin-turbo straight-six power unit already giving the BMW Z4 sDrive35i truly impressive dynamics and all-round performance is characterised in particular by its spontaneous and direct response to the gas pedal, fascinating free-revving performance, and unusually economical use of fuel for a car in this class.

Now the outstanding potential of this power unit is being put to even greater use in the new version of the BMW Roadster, features such as optimised air supply and increased boost pressure ensuring an even better flow of power with the same high standard of efficiency.

The combination of BMW Twin Turbo Technology and High Precision Injection offers a level of performance a naturally-aspirated power unit would only be able to provide with a larger number of cylinders and extra displacement, meaning far higher weight and significantly greater fuel consumption.

Instead, the BMW Twin Turbo power unit uses two small turbochargers which, through their low inertia, cut in from the start at relatively low engine speeds, each supplying three cylinders with compressed air. As a result, power and performance are built up with a level of spontaneity quite unusual on a turbocharged engine. The turbocharger system developed for the power unit of the new BMW Z4 sDrive35is maintains a high boost pressure throughout the entire load range. Peak torque now increased to 450 Newton-metres or 332 lb-ft comes from a low 1,400 rpm and is maintained consistently all the way to 4,500 rpm. Maximum output of 250 kW/340 hp, in turn, is delivered at 5,800 rpm.

Overboost function for particularly dynamic acceleration.
Modified engine management on the BMW Z4 sDrive35is also allows the use of an Overboost function briefly increasing engine torque under full load by another 50 Newton-metres or 37 lb-ft. The peak thus offered of 500 Newton-metres/369 lb-ft gives the car particularly fast, dynamic and powerful acceleration, the BMW Z4 sDrive35is completing the sprint from a standstill to 100 km/h (62 mph) in just 4.8 seconds.

Through its particular characteristics, the power unit offers a particularly intense experience of this supreme performance. The extra output of the optimized six-cylinder is maintained consistently throughout all load ranges, above all under very dynamic driving conditions.

When accelerating in the BMW Z4 sDrive35is, the driver feels the additional torque and muscle particularly at medium and high engine speeds. Following the policy of the BMW Group, finally, top speed of the BMW Z4 sDrive35is is limited electronically to 250 km/h or 155 mph.
