Alpina BMW | BMW Engines

Alpina Burkard Bovensiepen GmbH is an automobile manufacturing company founded by Burkard Bovensiepen in 1965 based in Buchloe, Bavaria Germany selling their own modified cars, based on original BMW manufactured cars. Alpina built cars are branded and registered as Alpina instead of BMW, although an Alpina can be bought and serviced at local BMW dealerships worldwide.

In 1965, Burkard established an Alpina BMW tuning business. The company worked on carburetors and revised cylinder heads. By 1970, with seventy employees, the original facility changed locations from Kaufbeuren to Buchloe.

Alpina performance works closely with BMW and their processes are integrated into BMW's production lines, thus Alpina is recognized as an automobile manufacturer, in contrast to other performance specialists which are aftermarket tuners.

For the 2011 model year, the Alpina B7's twin-turbo 4.4-litre BMW V8 is assembled by hand at Alpina's facility in Buchloe, Germany, before being shipped to BMW for installation, and the assembled vehicle is then sent back to Alpina for finishing.

Between 1968 and 1977, Alpina cars did very well in competition. The highlight was in 1970, when the team's cars won the European Touring Car Championship, the German Hillclimb Championship, Rally and track racing championships and the prestigious Spa 24 Hours.

Distinctive features of Alpina vehicles are 20 spoke alloy wheels, "Alpina Blue" patented metallic paint, in addition to expensive interior materials used to fabricate the exclusive interiors. A typical blue and green pattern is often used on interior parts such as leather and stitching and a host of different fabrics used in the upholstery and trim departments.

An interesting variant of the typically famous M20 engine of the mid eighties was Alpina's C2 which combined the wider bore of the M20 B25 with the slightly longer crankshaft of an M20B23, to create a 2552 cc stroked motor. These Alpina BMW engines put out 136 kW and 265 N·m.

Compared to cars from BMW's in house motorsport subsidiary, BMW M, Alpina's vehicles have placed a huge amount of emphasis on luxury, higher engine torque, and prefer automatic transmissions instead of manual gearboxes or semi-automatic transmissions. Unlike BMW M's own M5 which has a naturally aspirated, high-revving 5.0L V10, the Alpina B5 uses a supercharged 4.4L V8 which produces similar horsepower and greater torque at lower RPM.

BMW permitted Alpina to produce a high performance 7 Series car, however they did not want it to be a high revving BMW M version engine. For the BMW E65 7 series generation, the Alpina B7 was widely credited with being able compete with top performing Mercedes-Benz cars such as the Merc S600 and S63 AMG, Audi Quatro, Audi A8 and S8, while BMW's own 760Li was considered uncompetitive due to it's weight.

The 2011 Alpina B7 rolled out is a twin-turbo 4.4 litre V8 engine and 6 speed automatic transmission, is less expensive and faster than it's F01 stablemate, the 2010 BMW 760Li powered by a twin-turbo 6.0-litre V12. The B7's engine, derived from the BMW N63 that is found in the standard BMW lineup, matches the BMW 750i in fuel economy despite increased performance, plus its lighter weight than the 760Li's V12 engine gives the B7 considerably better weight distribution and handling than the 760Li.
