The heart of the B3 Bi-Turbo offers 265 kW (360 hp) at 5,500 - 6,000 revolutions per minute, as well as maximum torque of 500 Nm from 3,800 - 5,000 rpm. The B3 Bi-Turbo’s engine has a sporty engine’s willingness to rev to 7,000 rpm. Equally as present but usually reserved for diesel engines, there is vigorous torque from 1,500 rpm onwards. The result: a powerband broader than ever before experienced, guaranteeing both sporty and bullish driving dynamics
Technically, this is all made possible due to the exceptional BMW base engine with injectors centrally located over the pistons – the state-of-the-art in direct injection technology. For more than a year, ALPINA engineers researched, developed and tested, both on the engine test bench and on the road. Ever refining the ALPINA engine map to leverage all the advantages offered by modern direct injection, the potential inherent in the BMW foundation was maximised. The use of extremely durable MAHLE pistons allows for a maximum boost of 1.1 bar with a 9.4:1 compression ratio. The result, peak specific values of 89 kW (121 hp) per litre and a maximum average pressure of 21 bar
