A mere 30 examples of the track-only model are being built, and each looks near-identical to the GT3 racer they’re based on.
The most obvious change over the roadgoing 12C is the addition of a vast carbon-fibre rear spoiler, but there’s also a ground-hugging bodykit and huge rear diffuser.
The stripped-out interior gets full six-point harnesses for the lightweight bucket seats and an FIA-approved roll cage. Even the steering wheel is carried over from the 12C GT3 racer, although McLaren has still fitted air-con into the carbon-fibre dash.
Power is from the same twin-turbo 3.8-litre V8, but it delivers 621bhp – that’s more than the 493bhp GT3 racer and 616bhp road car.
The 12C GT Can-AM Edition will be built at McLaren’s HQ in Woking, Surrey, with production set to start in March. Each model will cost £200,000 more than the standard 12C, at £375,000.
