We’ve seen it in concept form before, when McLaren revealed their intentions to build the track-only P1 at Pebble Beach last year. The total power output has been increased, upping the power from its 3.8-liter twin turbo V8 from 727 horsepower to 789 hp, as well as tweaking the electric motor of the hybrid track monster to increase its previous contribution of 176 hp to 197 hp.
The car as given a significant lightness treatment, ditching anything that has nothing to do with performance as well as swapping the glass with polycarbonate sheets and a multitude of panels with carbon fibre. Track has been widened by 80 millimeters on the front and the whole thing sits 50 millimeters lower to the tarmac. New bodywork and the inclusion of a fixed rear wing give the P1 GTR a ten percent increase in downforce when it hits speeds upwards of 150 mph. The wing also has a DRS (drag reduction system) just as its Formula 1 cousin does, trimming the pitch of the wing from 32 degrees to zero, trading downforce for straight-line, overtaking speed.
Right, so you’ve smashed a few piggy banks and you’ve got just enough to get a P1 GTR of your own: what do you do with it? Owners of the car will be enrolled in the McLaren P1 driving program, where drivers will be fitness assessed, fitted to a seat, then prepped to race the cars on tracks like the Circuit de Catalunya in Spain and England’s Silverstone track.
Those of us not being shuttled out to McLaren’s Woking Technology Centre will join the rest of the world, seeing the P1 on the stand next to the McLaren 675LT as both make their debuts at the 2015 Geneva Auto Show.
