Developed by the motorsport division of the British marque, the McLaren 720S GT3X is extremely not legal for the road. Nor can it be used in races. Designed solely for the purpose of taking to track days, GT3X gives us what the 720S GT3 could be if road rules didn’t apply.
Powered by a handmade twin-turbo 4.0-litre V8 engine, the GT3X produces 710 hp under normal conditions. However, a push-to-pass boost button mounted on the steering wheel takes it to the next level by providing an extra 30 hp for limited periods of time, bringing the total power on the McLaren 720 GT3X to 740 hp.
The GT3X is based on the same carbon fiber MonoCage II carbon-fibre core as the 720S road car and the standard GT3. Pared-back and stripped of any non-essentials as well as McLaren’s signature luxury fittings, the GT3X weighs just 1210kg, 73kg lighter than its roadworthy counterpart. Going from 0-100km/h in 2.8 seconds, the McLaren 720S GT3X boasts a top speed of 340km/h.
