Representing the most dynamic and comfortable way to save, the eight-speed Sport automatic transmission in the BMW Z4 not only ensures incredibly soft gear changes and reduces background noise at high speeds, but also significantly reduces fuel consumption.
Only the rev counter will reveal how swiftly and comfortably the eight-speed automatic transmission changes gear. The individual gears are finely graduated so that the change takes place with small rev intervals and the transmission process itself is barely perceptible. At the same time, the engine is always held at the performance level that allows it to make optimum use of its strength and efficiency.
At high speeds the engine revs drop due to the additional gears, thus decreasing fuel consumption and also engine noise. The system is assisted by the newly developed and more efficient converter clutch – even if you use the electronic gearshift lever to change gear manually.
