Twin-turbo inline six-cylinder power for BMW Z4 sDrive35i dynamic and impressive all-round performance is characterized in particular by the direct and spontaneous response to accelerator, free tours fascinating performance, fuel economy and unusually for this class of car.

Now is the exceptional potential this engine is made even greater use in the new version of the BMW roadster, features optimized airflow and increased boost pressure to ensure a better flow of energy with the very high efficiency.

The combination of technology BMW Twin Turbo and High Precision Injection provides a high-performance normally aspirated power alone would be able to offer a greater number of cylinders and more transitions, ie a much higher, and fuel consumption significantly higher.

Instead, the power of the BMW Twin Turbo unit uses two small turbochargers, which by its low inertia, cut from the beginning of the relatively low engine speeds, each supplying three cylinders with compressed air. Consequently, the power and performance are built with a rare degree of spontaneity in a turbocharged engine. The system developed for turbocharged power unit of the new BMW Z4 sDrive35is maintains a high boost pressure throughout the load range. Maximum torque increased to 450 Newton-meters or 332 lb-ft comes from just 1400 rpm and remains constant up to 4500 rpm. Maximum power of 250 kW/340 hp, in turn, comes at 5800 rpm.

Overboost function particularly dynamic acceleration.

Modified engine management system for the BMW Z4 sDrive35is also enables the use of brief overboost function increases the torque of the motor full load of 50 Newton-meters or more 37 lb-ft. Then offered Newton-metres/369 top 500 lb-ft gives the car very fast, dynamic and powerful acceleration, the BMW Z4 sDrive35is pre-Sprint from zero to 100 km / h (62 mph), only 4.8 seconds.

Thanks to its characteristics, the power unit offers a particularly intense experience of the highest performance. Additional production six-cylinder engine optimization remains constant in the range of cargo, especially in very dynamic driving conditions.

The acceleration of the BMW Z4 sDrive35is, the driver feels the additional torque and muscle especially at medium and high speed of the engine. After the policy of the BMW Group has a top speed, and finally the BMW Z4 sDrive35is electronically limited to 250 km / h or 155 km / h.

High Precision Injection: an efficient way for high performance.

The BMW Z4 sDrive35is offers power and exceptional performance ever at any time. But that does not mean an increase in fuel consumption and emissions. On the contrary - an average consumption of 9.0 l/100 km (equivalent to 26.1 U.S. mpg) and CO2 emissions of 210 grams per kilometer of the test cycle of the EU, the new model also offers the same superior superior in this regard that the BMW Z4 sDrive35i with Sport Auto.

This exceptional balance between performance and the results of the fuel consumption of basic design and layout of the twin turbo six-cylinder BMW combines direct injection technology precision. So once again, the qualities of the direct fuel injection featured in this engine is very clear, piezo-injectors positioned in the cylinder head between the valves and therefore close to the spark plugs ensure a very precise dosing of fuel and clean burning.

The opening to the outside, the nozzles operate at pressures of up to 200 bar, divided into a conical spray of fuel into the combustion chamber. A further advantage, such as direct injection has a cooling effect that allows for greater compression and achieve a more efficient combustion.

With its concept alone, turbochargers also help reduce fuel consumption. Since the turbines are made of stainless steel is very resistant to high temperatures and therefore able to withstand temperatures over 1000 ° C or 1830 ° F, there is no need for fuel has increased from cooling. Especially at full load, providing significant fuel savings advantagein.

Other techniques are offered as standard in the BMW EfficientDynamics Brake Energy Regeneration, Electric Power Steering EPS, and on-demand control and management of ancillary units also reduce both fuel consumption and emissions.

Characteristic sound of the engine with a wave of dynamic power.

The modified six-cylinder also comes with special features on the engine block itself for even more strength and rigidity. The exhaust system in the BMW Z4 sDrive35is, in turn, are specially designed for this model, an appropriate sound engineering company gives the car a very particular sound pattern and really impressive.

This distinction is especially adapted to the BMW Z4 sDrive35is is provided by special sound components and modifications to the muffler. The driver and passengers experience so powerful Larsen for his willingness to perform, without the engine noise becomes intrusive and much less boring, at any time. Thus, the experience of sound is characterized by a particularly deep rumor focusing mainly on low frequencies.

Seven-speed sports automatic with a control card and a special optimized two inertial mass.
