This is the second- generation B7 Turbo, introduced in April 1984. Once again, Alpina claimed the title of being the fastest 4- door car in the world
Engine/ Gearbox
The engine is based on BMW’s 3.5L unit, which is standard version produces 218bhp. Alpina have made many changes to the engine such as a reprogrammed Motronic system, a modified cylinder-head, lighter Mahle pistons, a new camshaft, a special exhaust manifold and of course a KKK K27 turbocharger.
The engine has higher compression than the old B7 Turbo so Alpina have decreased the turbo boost to 0.7 bar, because they didn’t want the b& to have more than 300bhp. That’s exactly what it has, 300bhp and 501 Nm. The catalyst- version had 320bhp and torque of 509 Nm. The gearbox is a five- speed from Getrag.
Suspension/ Brakes/ Wheels
The B7 has the excellent Alpina- Bilstein suspension with progressive springs and gas- pressure dampers. The brakes are more powerful thanks to Girling discs all- around, ventilated at front. The wheels are in 16in high with 205/55 tires at front and 225/50 tires at rear.
Interior/ Exterior
The B7 has all the Alpina interior changes such as Recaro seats with Alpina upholstery, leather steering- wheel, gear knob, new instruments an so on. The visual changes include a deep front spoiler, rear spoiler and the wheels.
Performance

But the Swedish magazine Teknikens Varls tested the B7 Turbo it accelerated from 0-100km/h in an amazing 4.8sec, 0-200km/h in around 17sec and had a top speed of 270km/h
