2017 Alpina B5 saloon and Touring spotted
New sightings of both bodystyles show quad-exit exhausts and big brakes; B5 Touring isn’t expected to come to the UK
Both versions of the B5 will use BMW’s 4.4-litre twin-turbocharged V8, but power is likely to be raised close to that of the next M5, which is predicted to produce more than 600bhp.
BMW won’t be producing an M5 Touring, so the B5 Touring will be the hottest estate on offer in the new BMW 5 Series range. However, Alpina’s estate might not make it to the UK.
Expect the performance of both bodystyles to comfortably surpass that of the outgoing B5, with little more than four seconds required to complete the 0-62mph sprint and a top speed nudging 200mph.
The petrol V8-powered model will be joined by a more fuel-efficient diesel-engined equivalent. Called the D5, it will also be available in two body shapes and most likely have a turbocharged straight-six powerplant offering around 400bhp and close to 600lb ft.
The unit will be a developed version of the six-cylinder powerplant used in the new 550d, which itself produces 395bhp and 560lb ft.
As a result, the Alpina D5 is expected to have a sub-five-second 0-62mph time along with combined fuel economy of around 50mpg.
Both the B5 and D5 will gain their own Alpina bodykits and sit on Alpina’s 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.
Sources predict a £60,000 starting figure for the D5, while the B5 Touring could command something in the region of £100,000.
