Based on the BMW 850CSi which was presented to the public in 1992, the B12 5.7 Coupe was one of the fastest cars Alpina have ever made. The engine is based on the BMW Motorsport prepared 5.6-litre V12, which produces 380bhp. Alpina modified the engine capacity to 5.7-litres, as well as the intake, crankshaft and camshafts. A new exhaust system featuring Alpina’s own stainless steel catalytic converters was fitted, and the Motronic engine management system was reprogrammed. These changes improved output to 416bhp and 570Nm of torque.
The B12 Coupe was based on the already highly regarded BMW 850 CSi, typically Alpina finely honed the car with an extensive list of upgrades resulting in a very rapid and satisfying driving machine and the fastest BMW ever at the time. Performance was phenomenal – a top speed in excess of 180mph with a sub 5 second dash to 60mph. A handmade carbon fibre bonnet with NACA duct reduced weight and aided engine cooling, whilst uprated Alpina springs with Bilstein dampers and massive 285/35 rear tyres mounted on Alpina 20 spoke alloy wheels greatly aided road holding. The standard gearbox was a Getrag 6-speed manual, though the Shift-Tronic gearbox was an option.
This fabulous example is incredibly rare, being one of only three left hand drive Alpina B12 5.7 Coupes made with the six speed manual gearbox. The car has covered approximately 50,000kms from new with one owner, before being brought into the UK earlier this year.
We have seen much interest in BMW Alpinas of this period, which not only offer incredible performance, but mated to German build quality really offer an unbeatable package. A very good car, and highly collectible.
