"...with a V8 engine and a displacement of 4.4 litres, the previous B6‘s drivetrain is comparable to the well-known BMW ALPINA B5. The charging system in this engine differs from conventional solutions: not a turbo but also not a super-charger, which typically needs a great deal of power to operate, especially at high revs. The ALPINA V8 receives boost from a so-called ”radial compressor”, which one may visualise as a combination of a turbo and a compressor.

Over the course of the past year, ALPINA engineers have been thoroughly analysing the engine for additional potential, both on the test stand and on the road. Through further development of the camshaft overlap algorithms, the combustion process could be optimised, markedly lowering exhaust gas temperatures. This temperature delta is the basis for being able to increase power from 500 to 530 horsepower, while simultaneously raising torque from 700 to 725 Nm..."
