Without road-car regulations to hold it back, the McLaren P1™ GTR will push everything to the limit. Available only to McLaren P1™ owners, production of the track-focused GTR will begin when the 375th and final road car has been built.
The mid-mounted powerplant has an output of 1,000PS (986bhp) and includes an ERS-style push-to-pass system. The large fixed rear wing features a Formula 1™-derived Drag Reduction System and the wing mirrors have been repositioned to the A pillars to put them closer to the eye line of the driver and reduce aerodynamic drag. The car sits at a fixed ride height on race-prepared suspension over 19-inch motorsport alloy wheels. Below the rear wing is the exposed, centrally mounted inconel and titanium alloy exhaust. This all new straight cut twin pipe design has been developed exclusively for the GTR
McLaren P1™ GTR ownership will include participation in driving events at some of the world's most iconic circuits with specialist vehicle support. Also available will be access to McLaren racing simulators with driver training from experts that have helped develop and train Formula 1™ champions. In addition, exclusive consultations with the McLaren driver fitness team and Design Director Frank Stephenson will be included in the programme.
Together with one of the most exciting track-focused cars ever developed, the programme offers unprecedented access to the technologies, resources and people throughout the McLaren Technology Centre. Every experience will be unique and tailored specifically for each participant.
The bodywork is 'shrink-wrapped' as tightly as possible over the mechanical hard points of the car and the cockpit sits right at the centre. This approach helps to reduce frontal surface area, but also makes it easier to manage airflow over the surface of the bodywork and into the engine's roof snorkel intake and to the active aero components. It looks awesome, and it works very efficiently.
McLaren is yet to reveal performance figures, but the GTR will trump the road-going P1's 0-62mph of 2.8 seconds. Not much save a top fuel dragster will get off the line quicker.
But there's a whole lot more here than a twist of extra boost. The GTR uses the same carbon fibre 'MonoCage' chassis as the road P1, but sits lower on fixed suspension.
As you'll have spotted, it gets a bigger wing, fixed on carbon fibre pylons where the road P1 employs an active, retractable spoiler. This has allowed McLaren to remodel the P1's rear with a smooth, flowing surface, improving airflow and reducing turbulence.
There's a new centrally mounted exhaust rendered in Inconel and titanium, which, says the Woking outfit, 'maximises the aural characteristic to [...] further emphasise the McLaren sound.' This is Ron-speak for 'makes a bloody noisy racket'.
The P1's front track has been widened by eight centimetres, with the nose gaining a bigger splitter. New aero blades aft of the front wheelarches 'clean' the air from the front tyres, with an additional side panel at the rear channeling extra air into the radiator.
Those wheels are quick-release 19-inch racing alloys, with 270-section tyres at the front and 330s at the rear. Yep, 330s. The tyres are bespoke Pirelli slicks, which, says McLaren, offer improved grip and handling balance. In the dry, at least. In the wet, TopGear imagines those slicks will offer increased crashing.
There's also an onboard air jacking system - borrowed from McLaren's 650S GT3 racer - for quicker tyre changes.
