Power transmission in the BMW ALPINA B5 Bi-Turbo is taken care of by a new generation of the excellent 8-Speed Sport Automatic Transmission with ALPINA SWITCH-TRONIC. Further refined and adapted to the performance characteristics of the high-torque V8 Bi-Turbo in collaboration with ZF, the transmission offers exceptional driving comfort in all situations.
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 V8 Bi-Turbo 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 new BMW ALPINA B5 Bi-Turbo, allowing for a sprint from 0 – 100 km/h in just 3.5 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).
