The McLaren 720S GT3X represents the pinnacle of design and development for track performance based on the 720S platform.
A derestricted, race-prepared version of the M840T 4.0-litre twin-turbo V8 engine features upgrades and enhancements to provide a significant increase in power over the 720S GT3.
The lightweight 720S GT3X tips the scales at just 1,210kg (2,668lbs) and displays the extreme weight-saving efforts that have been taken into consideration to remove all non-essential or luxury items where possible, leaving the driver with just what they need to extract the best performance. Each of these measures combine to give the 720S GT3X a power-to-weight ratio of 620PS*-per-tonne.
