2018 BMW 5 Series ALPINA B5 BITURBO Spied – Video

 

The new Alpina sedan and wagon will be reportedly powered by the twin-turbo 4.4-litre V8 found in the latest B7, paired to an eight-speed automatic gearbox with the firm’s traditional Switchtronic shift buttons on the steering wheel.

Power is expected to remain at the same B7 levels, which translates into 600hp (608PS) and 590lb-ft (800Nm), figures that are nearly matching those expected by the upcoming BMW M5. Alpina is also developing the D5 model which is rumored to use a straight-six diesel with three turbos and a power output of at least 400hp.
