German tuner Alpina’s foray into hot-rodding BMW engines reportedly started in the early 1960s in an outbuilding at a typewriter factory in Buchloe, Germany. By 1965, founder Burkard Bovensiepen established an official BMW-tuning business. In 1983, after converting all manner of BMW models with performance and cosmetic enhancements, the German Federal Ministry of Transport recognized Alpina as an automobile manufacturer.
The B7 Turbo Coupe, launched in 1978, was Alpina’s first full conversion for BMW’s 6 Series platform. It featured a more powerful, turbocharged variant of BMW’s 3.0-liter, six-cylinder engine sourced from the contemporaneous 630 CSi. Additional improvements included upgraded Bilstein suspension, ventilated brake discs, and a body kit with signature Alpina multi-spoke wheels. Alpina has steadfastly continued this fine tradition of engineering all-encompassing modifications to each successive generation of BMW model. Nonetheless, the B7 Turbo has been, and continues to be, the company’s most famous and highly desired model.
BMW’s release of a 1982 engine update for their 6 Series, E24/1 chassis code, prompted a well-developed response from Alpina to further improve the performance capabilities of its own aftermarket products beyond what was now available from the BMW factory. Alpina shortly thereafter replied with the B7 Turbo/1, powered by a specially developed turbocharged engine displacing 3.5 liters and rated at 334 horsepower. Rather importantly, in opposition to BMW’s touring-focused base 6 Series, the B7 Turbo/1 was a true driver’s car only available with a Getrag five-speed manual transmission. For its own part, BMW’s Motorsport division released its performance-oriented M635CSi/M6 in 1986, though it was still significantly slower—and less expensive–than the Alpina B7 Turbo/1.
----- ----- ------ -----
When BMW introduced the updated E24 series (E24/1) in 1982, Alpina also updated the B7 Turbo Coupe
and renamed it to B7 Turbo Coupé/1.
At IAA 1984, the B7 Turbo Coupé/1 was officially launched.
Engine/Gearbox
When the E28 B7 Turbo/1 was introduced, the B7 Turbo Coupé/1 was launched with the 3,5 litre 330 bhp
B7/2 engine. Because the Coupé was heavier and more expensive so Alpina didn’t want it to be slower than
the saloon.
In late 1986, the B7 Turbo Coupé/1 received a 3,5 liter catalyst engine, called B7/3, which produces 320
bhp and 509 Nm of torque.
The B7 Turbo Coupé/1 was available with either a close-ratio manual gearbox or a overdrive 5-speed
manual gearbox.
For the Japanese market a small number of cars were built with an automatic gearbox.
Suspension/Brakes/Wheels
The B7 Turbo Coupé/1 has Bilstein gas-pressure spring units and progressive springs at front and gaspressure dampers and height-adjustable, progressive springs at rear.
The brakes are uprated with ventilated discs all around.
The wheels are 16″ with 205/55 tires front and 225/50 rear.
Interior/Exterior
The interior changes include a hand-stitched steering-wheel, a new gearknob, new instruments and sportseats in Alpina upholstery.
The exterior changes are a deeper front spoiler, a rear spoiler, the Alpina alloys and the optional Alpina
stripes.
Performance
Depending on the modelyear, Alpina claimed 0-100 km/h times of 5,9-6,7 seconds and top speeds of 250-
265 km/h.
