Next month McLaren will show what may be the world’s most expensive and powerful hybrid at the 2014 Pebble Beach Concours d’Elegance.

The P1 GTR design concept is a track-focused machine designed after customers asked for such a creation, and the estimated $3,357,000 car is due to go into production after the last of 375 P1s complete the production run for that already track-worthy car.

The plug-in hybrid P1 costs in the $1 million neighborhood, was sold out quickly last year, and the GTR boasts an estimated 1,000 metric horsepower (986 bhp).

Actual price and specs have yet to be made official, but McLaren has estimated the $3.57 million and horsepower over the 1,000 benchmark, but remaining to be seen is what it winds up being exactly.

This plus aerodynamic assist and other tweaks should help the car scurry around the track even better. A McLaren P1 was clocked at below seven minutes at the Nürburgring Nordschleife but McLaren has not said how much below this mark it went.

A Porsche 918 Spyder went 6:57 and while McLaren might have volunteered it beat this, it has not.

Don’t be surprised if the P1 GTR is quicker than a Porsche 918 Spyder, but for triple the cost of an already million-dollar car, perhaps that’s the least one would hope for.

McLaren’s GTR will be unveiled at the McLaren Brand Centre on the 18th Fairway at the Pebble Beach Lodge. Mclaren says, at 6 p.m. EST on Friday 15 August. It will then be on the Pebble Beach Concept Lawn over the weekend.
