Alpina B5 (F10)

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.
