McLaren 720S GT3X Debuts Ignoring Racing Rulebook With 710 HP

The body gains dive planes and a huge rear wing.

The newly launched McLaren 720S GT3X takes the brand’s existing track car and throws out all of the rules to create the ultimate circuit-carving machine. Plus, there is now room for a passenger to share the fun.

The GT3 class has stringent regulations that the X model doesn’t have to adhere to. For example, the 4.0-liter twin-turbo V8 now makes 710 horsepower (530 kilowatts) or 740 hp (552 kW) when activating the push-to-pass system, which is around 200 hp (149 kW) more than the standard version of the racer.

The tweaks to the engine include larger turbos and manifolds. McLaren builds each powerplant by hand and even blueprints the cylinder heads. To cope with the extra power, there’s an upgraded cooling system. For the full story, check out this article from Motor 1.
