1,000 HP. That’s the figure you came here to find out and there you have it: the new McLaren P1 GTR has 1,000 HP to play with. 800 of those come from the internal combustion 3.8-liter V8 engine and 200 from the electric motor.
But let’s not get ahead of ourselves here. The new GTR is a brilliant machine that doesn’t only have huge amounts of power but also plenty more innovations under the skin to boast with, just like the first car of this kind, the original McLaren F1 GTR, nearly 20 years ago.

The car will be making its world debut at Geneva in a few days and it will be wearing a new livery compared to the concept launched at the Pebble. This time it will be paying tribute to the original, featuring a similar theme that suggests going to the world-famous Harrods shop in London.

Huge aerodynamic changes

In order to be capable of running amongst the highest tiers of performance, the new GTR has been modified rather heavily. The front track, for example, is 80 mm wider (3.14 inches) than on the stock car while the entire auto sits 50 mm lower (2 inches) and has center-locking 19’’ motorsport ultra-light alloys.

In order to cut through the air easier, a new aerodynamic blade was installed on the lower part of the bodywork as well as a wing. This will sit 400 mm (15.7 inches) atop the body and will add up to 660 kg (1,455 lbs) of downforce at 150 mph (241 km/h) and will also retain the DRS (Drag Reduction System) of the road car. That means that the driver will be able to adjust its pitch from 32 to zero degrees, as he sees fit.

Weight saving was an intricate part of development

Other key differences compared to the road-legal car refer to the weight factor. For track purposes, the GTR had to be lighter on its feet so the engineers decided to lose some pounds off of its waist.

The windscreen, for example, is just 3.2 mm (0.12 inches) thick and is identical to the stock car but other than that, everything else has changed, like the side windows that are made of polycarbonate now and have a special window on the driver’s side for various purposes.

The roof is now made of carbon fiber panels just like the engine bay cover while the stock exhaust was changed for a titanium-inconel one that saves another 6.5 kg (14 lbs) in the scheme of things. Overall, 50 kg (110 lbs) were shed off the standard model.

If you want to see it in the metal (and it looks absolutely stunning), you’ll have to come check it out at the Geneva Motor Show on March 5. We’ll be bringing you live photos from the venue, in case you can’t make it.
