The latest generation 8-Speed Sport Automatic Transmission with ALPINA SWITCH-TRONIC is specifically refined and adapted to the torque and performance of the straight-six cylinder diesel engine in collaboration with ZF, it offers exceptional shift comfort. In Automatic Mode the combination of eight gears and high engine torque makes for relaxed, luxurious cruising at low engine rpm even when travelling at speed.
The 8-speed sport automatic transmission combined with ALPINA typical high torque output at low engine speeds allows effortless, relaxed and economical driving in high gears and outstanding cruising comfort on long journeys. Simultaneously all components of the transmission such as the torque converter with lock-up clutch, the planetary wheel sets and the inner cooling are designed to specifically cope with the high torque output of the engine. This means that no torque reduction is necessary during upshifts when utilising Launch Control or when using the sportiest configuration of the Manual Mode. This contributes significantly to the striking longitudinal dynamics of the BMW ALPINA XD3 and XD4 models, allowing for a sprint from 0 – 100 km/h in just 4.6 seconds.
The transmission also features the latest Comfort and Efficient Dynamics functions such as Connected Shift (use of navigation data for an anticipatory shift strategy based on traffic routing) and coasting (decoupling of the engine and transmission when coasting).
