Alpina says that the car’s twin-scroll turbocharger engine has also been tuned to offer strong performance at low revs. It backs this up with an impressive claim that 494lb ft of torque is available at just 2000rpm.
The car maker attributes the engine’s strong performance to effective cooling systems – which include large volume intercoolers – and its use of high-performance Mahle pistons and NGK spark plugs. Along with other high-performance parts, these enable the engine to run with 20psi of boost pressure and a compression ratio of 10.0:01.
Back pressure is reduced with the fitment of a model-specific stainless steel exhaust system, which features active valves to allow drivers to adjust the sound by switching the Driving Dynamic Control (DDC) switch between Comfort and Sport modes.
The car’s chassis settings can also be controlled through DDC, with an adjustable air suspension system that in conjunction with adjustable dampers and Road Preview, which uses GPS to adjust the car’s suspension for upcoming corners.
The car’s ride height can be manually adjusted, and it can also automatically adjust according to driving scenarios. Above 140mph, for example, the car lowers itself by 2cm, helping to lower centre of gravity and therefore improve high-speed stability. This squat position also increases front wheel camber, which makes for more direct steering responses.
Conversely, drivers can raise the ride height by 2cm when driving at speeds of 20mph and under, to help clear obstacles such as speed bumps and kerbs.
The car sits on 20in Alpina classic wheels as standard, while 21in items are available as an option. The car is stopped by 394mm front and 368mm rear discs and four-piston calipers all round.
The B7 is set to cost from £115,000, with first deliveries due this Autumn.
Alpina has also confirmed that the upcoming B6 will be sold in the UK market. It should feature the same 4.4-litre V8 engine as the B5 and B7, and, like those cars, will be available in the UK exclusively as a rear-wheel-drive car.
