Alpina is set to launch it new B4 Bi-Turbo in the UK at this month’s Goodwood Festival of Speed.
Based on the latest 3 Series and 4 Series platform, the tuned petrol-engined car will start from £58,950 for the Coupe, rising to £62,950 for the Convertible variant – this features an insulated metal roof that closes in 20 seconds at up to 11mph.
Power comes from a re-engineered version of the 335i’s 3.0-litre straight six engine, meaning 0-62mph takes 4.2 seconds in the hardtop – almost half a second quicker than an entry-level Audi R8 Coupe – with the drop-top taking 0.3 seconds longer. A four-wheel drive version that won’t be available with right-hand drive will apparently cut this to 4.0 seconds.
Over here, the 402bhp and 600Nm of torque will be fed to the rear-wheels via a modified eight-speed automatic gearbox. Alongside the improved output, Alpina claims the B4 Bi-Turbo will manage 37.2mpg while emitting 177g/km of CO2, although in convertible guise expect only 35.3mpg at best and 186g/km CO2.
The 50-strong engineering team likewise worked on improving the suspension, steering, aerodynamics and interior. Styling changes were honed in BMW’s wind tunnel, and there’s standard kit in the form of Adaptive M Sport Suspension, leather upholstery, climate control, bi-xenon headlights and electrically adjustable heated sports seats.
Alpina logos adorn the seat backs and door sills, with a Lavalina leather-trim steering wheel and Alpina Blue instruments further helping the interior stand out. 20-inch alloys and a quad exhaust system serve a similar function for the exterior.
Available in Alpina Blue or Green body colours, options can be chosen from BMW’s spec list, or else requested directly from Alpina.
