This track-focused version of the B3 Biturbo is built to celebrate the success that Alpina has enjoyed in the FIA with its B6 GT3, which is why this show version wears a similar green, silver and blue livery. Under the hood Alpina have managed to squeeze another 8 HP, up to 408 HP, from the direct-injected, 3L twin-turbo straight-six, with 398 lb/ft of torque available at 4,500 rpm. This allows the GT3 to sprint from 0 to 60 mph in 4.6 seconds, which is edging on M3 territory.
..and a serious braking upgrade. This incudes 6-pot Alpina calipers at the front with massive 380 mm discs, with slightly smaller 4-pots and 355 mm discs at the rear. These hide behind lightweight 19" Alpina Classic wheels, 25% lighter than the stock 18s, bringing a 10 kg weight saving. Michelin Pilot Sports Cup + take care of providing the grip. However it's the special height adjustable race tuned suspension that really makes the car. The dampers offer 12-adjustments on compression and 18 on rebound allowing the driver to fine tune the chassis to different tracks and grip conditions.
