The modifications include large 44 mm (2 in) Honeywell turbochargers, reinforced cylinder heads, NGK spark plugs, high strength MAHLE pistons and an Alpina specific ECU.
The engine is mated to a modified 8-speed automatic transmission manufactured by ZF Friedrichshafen called the "Switch Tronic" gearbox by Alpina.
The transmission has a manual shifting mode which allows the driver to change gears using two aluminium buttons on the back of the steering wheel.
The car has 20-inch multi-spoke alloy wheels with Michelin Pilot Sport tyres having sizes of 255/35ZR20 at the front and 285/30ZR20 at the rear.
The exhaust system, shared with the B6, is a titanium unit from Akrapovic with quad-exhaust tips and electronically controlled bypass valves.
A notable feature of the engine was the use of direct fuel injection which reduced gear shift timing to 180 milliseconds.
The switch to a titanium Akrapovic exhaust system saves a further 17 kg (37 lb) of weight while also reducing back pressure.
The interior had a Forest Green and black Nappa leather upholstery with contrast yellow stitching and ceramic finishing on the centre console paying homage to the 1982 B7 S Turbo.
