BMW's new 6spd auto

Recommended Posts



BMW has released more information on its new six-speed automatic gearbox, which will show up in the 2007 3-Series Coupe. The gearbox uses a dedicated electronic control unit that permanently monitors the position of the gas pedal, registering the intensity of the pressure exerted by the driver on the gas pedal and determining whether and to what extent the driver wishes to accelerate. Retrieving data on the road speed of the car, engine speed and the steering angle, the control unit also detects current driving conditions at all times, considering furthermore whether the car is driving uphill or downhill. By taking all these criteria and many others into account the management unit is able to determine which gear is the most suitable. The harder and faster the driver depresses the accelerator, the lower the gear

The system is designed to give the automatic transmission increased precision, without any time-consuming search for the right gear, which the driver would experience as an unwanted delay.

100 milliseconds response time

According to BMW, the new six-speed automatic transmission sets new standards for shift times. The new six-speed automatic transmission completes every gearshift process faster than the vast majority of sporting drivers experienced in shifting gears manually.

In a kick-down situation at a speed of 50 mph in sixth gear, the transmission can shift in just 100 milliseconds to second gear. While this is happening, the control unit sends a positive force pulse to the engine, which immediately increases its speed from approximately 1,400 to more than 5,000 rpm.
