Local News: BMW Z4 sDrive35is Hits Town

The new BMW Z4 sDrive35 offers an even higher standard of performance ensured firstly, by the modified straight-six power unit with BMW Twin Turbo Technology and High Precision Injection, and also 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.

Appropriate optimisation in engine technology increases maximum output of the 3.0-litre power unit to 340 hp. Peak torque is 450 Nm, increasing briefly with the Overboost function to 500 Nm. 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 in just 4.8 seconds.

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 Nm from a low 1,500 rpm and is maintained consistently all the way to 4,500 rpm. Maximum output of 340 hp, in turn, is delivered at 5,900rpm.

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 Nm. The peak thus offered of 500 Nm gives the car particularly fast, dynamic and powerful acceleration, the BMW Z4 sDrive35is completes the sprint from a standstill to 100 km/h 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, top speed of the BMW Z4 sDrive35is is limited electronically to 250 km/h.

The BMW Z4 sDrive35is offers its outstanding power and performance consistently at all times. But this does not mean an increase in fuel consumption and emissions. On the contrary – averaging fuel consumption of 9.4 litres/100 kilometres and CO2 emissions of 219 grams per kilometre in the EU test cycle, the new top model offers the same superiority also in this respect as the BMW Z4 sDrive35i with Sport Automatic.

Further technologies offered as standard by BMW EfficientDynamics such as Brake Energy Regeneration, EPS Electric Power Steering and on-demand control and management of ancillary units likewise help to reduce both fuel consumption and emissions.

The seven-speed Sport Automatic with double clutch operation featured in the BMW Z4 sDrive35is likewise offers the very best in driving dynamics and efficiency. A particular highlight in this case is the two-mass flywheel laid out particularly for an even higher level of power and performance, offering even greater strength and stability, and naturally handling high engine torque of up to 500 Nm without the slightest problem.

The seven-speed Sport Automatic with double clutch operation shifts gears without the slightest interruption of torque and engine power, offering the driver the choice of an automatic gearshift or the manual selection of gears. The fast and particularly smooth change of gears Media information: The BMW Z4 sDrive35is.ensures unusually harmonious acceleration and serves in addition to reduce both fuel consumption and emissions.

The BMW Z4 sDrive35is comes with a choice of six paintwork colours. In addition to Alpine White and the metallic colours Titanium Silver, Sapphire Black, Space Grey and Deep SeaBlue, the Z4 Roadster is now available for the first time in Melbourne Red metallic.

The BMW Z4 sDrive35is will be introduced at Performance Motors showrooms from end July 2010.
