Alpina Burkard Bovensiepen GmbH & Co. KG is an automobile manufacturing company based in Buchloe, in the Ostallgäu district of Bavaria, Germany that develops and sells high-performance versions of BMW cars.

[5] Alpina's roots can be traced back to 1962, when Burkard Bovensiepen developed a Weber dual carburetor for the BMW 1500.

In its first years, Alpina established its core competency by tuning carburetors and crankshafts to extract more power from BMW engines, elements that eventually defined the company's logo, which came into being in 1967.

The production process switches between fine tuning the engine, delivering it to the BMW plant, marrying engine and body there, and bringing it back to Alpina for interior upgrade with Alpina's specific components, again all in a hand-made process that allows only limited production numbers.

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.

It is available as a Saloon or Touring version with a 3.0-litre straight-six, bi-turbocharged diesel engine with 257 kW (349 PS; 345 hp) of Power and 700 N⋅m (516 lb⋅ft) of torque.

[29][additional citation(s) needed] The Alpina D5 S debuted at the 2017 Frankfurt Motor Show[30] in all-wheel drive only sedan and Touring variants.

The Alpina B7 features a 447 kW (608 PS; 599 hp) 4.4 litre twin-turbocharged V8 engine delivering 800 N⋅m (590 lb⋅ft) of torque and a more luxurious interior.

The face-lifted model, unveiled in February 2019, has a better power band which allows better performance, with a 0–100 km/h (62 mph) acceleration time of 3.6 seconds.

Alpina reworked the head which was ported and polished, installed harder valve springs and a hotter cam.

The first C2 combined the wider bore of the M20B25 with the slightly larger 76.8 mm (3.02 in) crankshaft of an M20B23, to create a torquier engine of 2552 cc.

[citation needed] The C2 /1 2.7 used the 325e eta model engine block, crank and rods, but with custom flat head pistons provided by Mahle.

The C2/1 2.7 made 210 bhp (157 kW) with 267 N⋅m (197 lb⋅ft) of torque and was the fastest E30 available at the time[citation needed] (227 km/h (141 mph) top speed).

The head is decked ~ 1 mm to improve CR to 9.6:1 and matched with custom domed KS or Mahle pistons.

It features upgraded brakes with 380 mm discs, a Drexler limited slip differential and fully adjustable coilovers by KW at all four corners.

[57][58] The most noticeable changes were on the exterior: The B3 GT3 sports a carbon fibre rear wing, a special front splitter and 19" lightweight Alpina GT3 Classic wheels, painted in Himalaya Grey.

The car could be ordered with an extra set of lightweight wheels (also 19" Alpina GT3 Classic, but equipped with Michelin Pilot Sport Cup+ tires) for use on the track.

The car featured a bored-out 230 hp (233 PS; 172 kW) 3.0-liter straight-six fitted with three double barrel carburetors.

Compared to the E60, the B5 has larger brakes, a new suspension with Electronic Damper Control, a stainless steel silencing system with polished double tailpipes and the typical Alpina changes to the interior and exterior.

At low speeds, it spontaneously responds as a conventional displacement compressor, but it can also immediately provide the thrust of a turbo.

The reaction time is 1/10 s. In manual mode, the driving feeling is similar to the shift dynamics of a dual clutch transmission.

For the E65 7 Series generation, the Alpina B7 was widely credited with being able to hold its own against top performing offerings from Mercedes (including AMG) such as the S600 and S63 AMG, Audi (particularly quattro's Audi S8), the Bentley Flying Spur, and Jaguar XJ Supercharged, while BMW's own top-of-the-line V12 760Li was considered uncompetitive.

[1][2] BMW of North America, LLC offered 800 Alpina B7s as limited edition models for 2007 and 2008, all of which quickly sold out.

By using conventional, softer-sidewalled tires, compared to the reinforced sidewalls of run-flats, Alpina engineers were able to stiffen the B7's suspension for better handling and still improve the ride quality over that of a stock BMW 750i.

It is powered by an Alpina modified BMW M70 V12 (shared with the E32 B12 5.0) producing 257 kW (349 PS; 345 hp) and mated to an automatic transmission.

Powered by an Alpina tuned version of BMW's N63 4.4L V8 Bi-Turbo, the B8 produces 630 PS (463 kW; 621 hp) and 800 N⋅m (590 lbf⋅ft) of torque.

Alpina tuned suspension and handling provided drivers with a Comfort+ and Sport+ mode for ideal ride comfort and performance.

[101] The Alpina was a departure from the hard-edged sporting focus of the original car, and elements of the new grand touring intent were evident throughout this final edition.

A new, softer grade of Nappa leather replaced the Z8's less supple specification, and special Alpina gauges were featured on the dash cluster.

An Alpina steering wheel with three solid spokes replaced the original, which could not be retrofitted with shift paddles for the automatic.
