ALPINA B7 TURBO(e-24)

The B7 Turbo was introduced in December 1978 and it was the first 6-series car with full Alpina conversion(bearing its own identification number). At first it was called Alpina 630 Turbo but later Alpina changed the name to B7 Turbo. Over a ten year period, between December 1978 and June 1988, a total of 313 cars were made.

Engine/Gearbox

The engine is the same 3,0 litre turbocharged six as in the B7 Turbo saloon. It is based on BMW´s 3,0 litre unit. The entire engine has been carefully rebuilt using components specifically designed for the engine. For example lower-compression Mahle pistons and a new fuel injection system. The B7 also had variable boost control which regulated the turbocharger between 0,6 bars to 0,90 bars of boost, corresponding to between 250-300 bhp. Read more about the engine in the 5-series section. When the e-28 B7 Turbo was introduced the B7 Turbo coupé recieved the 3,5 litre 330 bhp engine. That was 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 recieved the 3,5 litre catalyst engine. That engine produces 320 bhp and 509 Nm of torque. The B7 was available with either a close-ratio gearbox or a overdrive 5-speed  gearbox. Both gearboxes were manual.

Suspension/Brakes/Wheels

The B7 has Bilstein gas-pressure spring units and progressive springs at front and gas-pressure dampers and height-adjustable, progressive springs at rear. The brakes are uprated with ventilated discs all around. The wheels are 16in high with 205/55 tires at front and 225/50 at rear.

Interior/Exterior

The interior changes include a hand-stitched steering-wheel, a new gearknob, new instruments and sport-seats in Alpina upholstery. The exterior changes are a deeper front spoiler, a rear spoiler, the Alpina alloys and the traditional Alpina stripes but they were optional.

Performance

This is a very fast car. Alpina have claimed 0-100 km/h times of 5,9-6,7 seconds and top speeds of 250-265 km/h depending on what year the car is built.
