Hot Alpina B5 Biturbo gets 600bhp BMW V8, £89,000 price tag
Alpina’s hot B5 will be joined by a 400bhp D5 version based on BMW’s 550d
First deliveries of the B5 Biturbo will take place in March, with the saloon priced from £89,000 and the Touring from £91,000. Single-digit numbers are expected and there’s no limit on production, although a larger number of the more frugal, diesel D5 is expected.
Both saloon and Touring versions of the petrol-engined hot 5 Series variant use BMW’s 4.4-litre unit, which also outputs 590lb ft of torque. The new car accelerates from 0-62mph in 3.4sec and tops out at 204mph. That performance ranks the new Alpina slightly above to the BMW M5, which produces 592bhp, accelerates to 62mph in 4.2sec and has a top speed of 190mph.
BMW won’t be producing an M5 Touring, so the B5 Touring is be the hottest estate on offer in the new BMW 5 Series range. The D5 estate has been given upgraded twin-scroll turbochargers nestled between the cylinder banks, as well as upgraded airflow, intercoolers and brakes.
Rear-wheel steering is used, allowing the car to turn the rear wheels up to an angle of 2.5deg, and a mechanical limited-slip differential is available as a £2500 option.
The petrol V8-powered B5 will be joined by a more fuel-efficient diesel-engined equivalent called the D5, which is yet to be shown. This will also be available as a saloon or estate and will most likely have a turbocharged straight-six engine with around 400bhp and close to 600lb ft.
The unit will be a developed version of the six-cylinder powerplant used in the new BMW 5 Series 550d, which produces 395bhp and 560lb ft.
As a result, the Alpina D5 is expected to have a sub-five-second 0-62mph time as well as combined fuel economy of around 50mpg. The standard B5 Biturbo saloon achieves 26.9mpg and emits 240g/km CO2, while the estate returns 26.2mpg and 247g/km.
Both the B5 and D5 have Alpina’s own exterior styling and familiar multi-spoke wheels. Performance-honed suspension and gearbox settings will also give the two hot estates sharper responses than those of BMW’s regular estate offerings.
UK pricing is yet to be confirmed for this diesel variant, but the D5 will likely be closer to £60,000 when it arrives.
