I am toying with the idea of selling the car, I genuinely enjoy driving it

Here’s some Alpina Info -

The B7 uses a modified version of the 4.4-litre N62 V8 engine, designated the H1 by Alpina. Changes to the engine include an Alpina specific block, a forged crankshaft and lower compression high strength Mahle pistons.The engine uses a centrifugal type supercharger, the first to be used on an Alpina automobile. The engine also has an Alpina specific modified ECU and retains BMW's Valvetronic Variable Valve Timing.

500 PS (368 kW; 493 hp) between 5,250 and 6,000 rpm and 515 lb⋅ft (698 N⋅m) of torque available

The B7 has a bespoke Akrapovic exhaust system

The heat generated by the 0.8 bar of boost pressure from the supercharger is managed by a high-transfer rate air-to-air intercooler. The B7 uses the rear axle from a 745d in order to handle the high torque generated by the engine. The compressor is driven by a dedicated poly V-belt which is separate from the other serpentine belts on the engine. At low rpm, the clutch de-couples the compressor from its drive belt, resulting in high torque at the low rpm range. The air from the supercharger was guided to the engine by an air-to-air intercooler. The turbine of the supercharger rotates at speeds of up to 100,000 rpm due to a planetary gear set, an adjustable second throttle plate allows the turbine to keep rotating at low rpm range.

The engine is mated to a 6-speed ZF automatic transmission called Switch Tronic which has a manual shifting mode allowing the driver to change gears via buttons located on the back of the steering wheel.

The B7 was mostly assembled at the BMW plant in Dingolfing alongside the 7 Series.The engine was initially manufactured at the BMW Steyr plant and was then sent to Alpina at their Buchloe factory for final assembly. The engine was sent to the BMW factory to be installed in the car where the car was assembled and painted in Alpina specific exterior colours. The completed cars were sent back to the Alpina factory for final inspection and finishing touches.


Alpina B7 (E65) (post facelift)
The interior of the car has Lavalina leather upholstery and curled maple wood trim. The changes include Alpina gauges, Alpina logos and badges and a three-spoke sports steering wheel. The BMW iDrive system was also included as standard.

The exterior changes include a rear lip spoiler, 21-inch Alpina classic multi-spoke alloy wheels wrapped in Michelin Pilot Sport 2 tyres (measuring 245/35 ZR21 at the front and 285/30 ZR21 at the rear), a front valence and a chin spoiler. The B7 achieved a drag coefficient of Cd=0.31 when tested in the BMW windtunnel.

The B7 uses the braking system developed by BMW for the 760Li which has bigger discs than a 745i (measuring 14.72 in (373.9 mm) at the front and 14.57 in (370.1 mm) at the rear) and floating calipers. The suspension system uses Sachs shock absorbers and Eibach springs
