McLaren has confirmed more technical details of its track-only Senna GTR, as well as releasing a sketch of the 2019 production car.
Previewed at March's Geneva motor show, the Senna GTR is described as the fastest machine to roll out of Woking this side of a Formula 1 car. It's priced at £1.1 million plus local taxes, and production is capped at 75 examples. All have already been sold, with deliveries due to commence next September.
The standard Senna's 4.0-litre V8 is uprated in the GTR to produce 814bhp, up from 789bhp, while torque is unchanged, at 590lb ft. No kerb weight figure has been released yet, but McLaren claims that the GTR's power-to-weight ratio will 'comfortably exceed' that of the standard Senna.
The final bodywork, previewed in a new design sketch, is based around a chassis with a wider front track. Made almost exclusively from carbonfibre, it features wider front wings, a larger front splitter, a bespoke rear diffuser and repositioned active rear wing. The result is a full 1000kg of downforce, up 200kg over the existing Senna. Under braking, the car is also capable of 3g of decelerative force – 20% more than the Senna.
