The track-only McLaren P1 was confirmed earlier this month and here is the very first teaser, along with engine output and pricing details.
The track-only P1 will go into production when the 375th and final example of the road car has been completed sometime in 2015, and in homage to its race-winning ancestor, the F1 GTR, the most powerful McLaren to date will be named the McLaren P1 GTR.
As the teaser shows the car will get some big aerodynamic changes, generating better downforce than the road legal car.
The engine is tuned to produce 1,000PS (986bhp) up from the road legal cars output of 903bhp (916PS).
There are also race-proven slick tyres, a widened track and more aggressive and distinctive styling.
The P1 GTR will be produced in very limited numbers, priced at £1.98m. In comparison the road-going model is priced from £866,000.
