Background
The Alpina B3 GT3 was launched at the 2011 Tokyo Motor Show to celebrate the wining that year’s DAC GT Masters championship with the Alpina B6 GT3 racecar.
Based on the coupé version of the B3 S BiTurbo, production was limited to just 99 units and customers could choose from three different colours: Black Sapphire; Mineral White; Alpina Blue II - or a B6 GT3-inspired bright green wrap.
Power comes from the same engine that was fitted to the B3 S BiTurbo, albeit it now silenced by an Akrapovic titanium rear silencer with double 115 mm tailpipes, a move that liberated another 8hp giving the driver access to 402bhp in total. Torque is a stump-pulling 398lb.ft, by the way.
(Interestingly, the titanium exhaust also offers an 11kg weight saving into the bargain, as well as one of the best exhausts notes of the period.)
The only gearbox option was a ZF 6-speed 6HP19T Switch-Tronic unit, with a limited-slip Drexler differential ensuring maximum traction.
Suspension is via an adjustable KW coilovers on all four corners with camber plates on the front. You can set the suspension to any one of 12 damper compression setting positions, with no fewer than 18 available for rebound.
Stopping power comes via six-piston calipers that grip 380mm discs on the front, while the rear must make do with four-piston calipers and 355mm discs. #firstworldproblems, eh?
The B3 GT3 sits on model-specific forged 19-inch alloy wheels finished in Himalaya Grey, a hue that is - again - unique to this model. The wheels, at just 10kgs a piece, are also 25% lighter than those fitted to the B3 S BiTurbo.
The end result is a very serious piece of kit, so serious, in fact, that Autocar magazine said of it: “You just can’t drive it hard and fast enough on the public highway to get anywhere near the full potential of its chassis, marvel that it is, although you can have a whale of a time trying. This is a proper track thoroughbred.”
