BMW automatic transmissions
Most newer BMW vehicles use the ZF 8HP Steptronic gearbox — an 8-speed classic AT with torque converter, known for smooth operation, quick shifts and low fuel consumption. Sportier models (M Performance, M series) often use DCT (dual-clutch) or newer ZF SMG variants. Older models (up to 2010) also had 6-speed AT gearboxes from ZF.
