Proof enough then, that McLaren is quite serious about the business of making the P1 GTR the best driver's car in the world on track. What you see here are the first official pictures of its interior, and it's unsurprisingly quite Spartan.

First off, you should know that the P1 GTR is an even harder, more powerful version of the already quite powerful ‘standard' P1. Its combination of 3.8-litre twin-turbo V8 and electric motor now produces a whopping 986 horsepower, 83hp more than the ordinary P1.

The car is currently undergoing dynamic testing at "a range of international race circuits", and these first un-camo'd images show off the GTR’s Batmobile-like aerodynamic updates.

We also get a good look at the inside – and that wheel. As mentioned, it takes cues from the MP4-23, with the mode switches in the centre, DRS and IPAS buttons on the top corners, the engine start in the bottom right hand corner and a KITT-style ‘boost' button included too. All in, it looks bloody excellent.

There are lightweight DTM-style seats with six-point racing harnesses – specially set up for each individual driver – with a HANS-approved carbon fibre seat shell. And though it's pretty austere inside, there's still air-con, a sure necessity when piloting a near-1,000hp track racer weighing little more than a sports shoe.

Each P1 GTR owner will get a bespoke one-to-one driver programme to ‘optimise' his or her driving skill, at "the most iconic F1 circuits across the world".

Probably a wise move, considering just 30 are expected to be built, each costing somewhere in the region of £2 million (about $3.2m). Be afraid.
