Watch the highlighting features of the McLaren 720S GT3X
This track-only version of the McLaren 720S comes with faster acceleration, better brakes, and more power than the GT3. The race car is powered by a 4.0-liter twin-turbocharged V8 engine that is expected to produce 200 horsepower more than the McLaren 720S GT3. The interior has been modified to allow space for an additional front seat to take a passenger along for the ride. At the heart of the McLaren 720S GT3X is the light but strong carbon fiber MonoCage II chassis.
