Standard interior features included an Alpina instrument cluster with a special 300 km/h (186 mph) speedometer and badging.

Mechanical changes included increased engine power to 257 kW (350 hp) and 470 N⋅m (347 lb⋅ft) of torque at 4,000 RPM.

The engine was mated to a 4-speed automatic transmission manufactured by ZF Friedrichshafen and had modified gear ratios.

These modifications allowed the engine to have a power output of 257 kW (350 hp) at 3,500 rpm and 470 N⋅m (347 lb⋅ft) of torque at 4,000 prm.

The interior was customised to the customer specifications and contained a wide range of options with Alpina instrument cluster and badging being standard.

The interior had anthracite leather upholstery with blue contrast stitching along with Alpina instrument cluster, wood trim, and a wooden gear knob as standard but was customisable according to the customer specifications.

The modifications included increased displacement to 5.7-litres, a modified air intake system, new cylinder heads, and higher compression Mahle pistons.

These modifications allowed the engine to have a power output of 285 kW (387 PS; 382 hp) and 560 N⋅m (413 lb⋅ft) of torque.

The system allowed the driver to put the car in a manual shift mode in which gears were changed via buttons on the back of the steering wheel.

[12] The interior had anthracite leather with contrast stitching as standard equipment along with wood trim and an Alpina instrument cluster.

The modifications include enlarged engine capacity to 6.0-litres, higher compression Mahle aluminium pistons, modified camshafts, and air intakes, Bosch Motronic M5 2.1 fuel injection, and a new exhaust system with a catalytic converter having an electronically heated metal catalyst.
