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.
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.
The B7 Turbo Coupé/1 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 16″ with 205/55 tires front and 225/50 rear.
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 optional Alpina stripes.
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.
Between 1984 and 1989, a total of 130 cars were made.
