What kind of clutch does BMW use?
2 Answers
BMW uses a dual-clutch transmission. Dual-clutch transmission: The dual-clutch is a type of automatic transmission. Unlike traditional automatic transmissions that use a torque converter, the dual-clutch is a mechanical automatic transmission with two power output shafts. Each shaft is connected to a separate clutch—one controls gears 1, 3, 5, and 7, while the other controls gears 2, 4, 6, and reverse. During gear shifts, while one set of gears is engaged and transmitting power, the other set is already prepared, ensuring uninterrupted power delivery. This results in faster gear shifts and more rapid acceleration. By utilizing a dual multi-plate clutch design, power transmission remains continuous, significantly reducing fuel consumption. Dual-clutch maintenance: When waiting at a red light, it is advisable to shift into Neutral (N) gear. Keeping the transmission in Drive (D) while braking can potentially harm the dual-clutch transmission over time.
Many BMW cars now use automatic transmission clutches, eliminating the need for a clutch pedal. This system employs a torque converter, acting like a soft connection to ensure smooth gear shifts, especially in urban traffic jams. In standard models like the 3 Series or 5 Series, an 8-speed automatic transmission is mostly standard, provided by ZF, known for its quick response and durability. If you prefer a manual option, BMW offers very few choices, mainly in entry-level models or older versions. High-performance M Series favors dual-clutch transmissions for ultra-fast shifts, ideal for track driving. Why does BMW make these choices? They aim to balance comfort and driving pleasure—automatic clutches reduce fatigue while optimizing fuel efficiency through electronic control. For daily driving, issues are rare, but it's recommended to check the transmission fluid every 3 years to ensure smooth operation.
