The 2021 McLaren 720S GT3X has been unveiled, a special edition based on the 720S GT3 racer with "increased engine output, improved aerodynamics, and increased stopping power."

Drive comes from a modified example of the existing twin-turbocharged 4.0-litre twin-turbocharged V8, sending 530kW to the rear wheels via a seven-speed dual-clutch transmission during normal driving – matching the road-going model on grunt.

However, a further 20kW can be extracted via a steering wheel-mounted ‘boost’ button, allowing for a maximum output of 550kW.

An offical 0-100km/h time is yet to be announced. However, McLaren claims the GT3X is "significantly" faster than the standard model – likely both around a track and in a straight line – which already completes the benchmark sprint in an impressive 2.6 seconds.

According to the car's engineers, the GT3X’s cooling system has been heavily upgraded, as has the aerodynamic package and carbon-ceramic disc brakes.

A passenger seat – missing from the regulation-bound GT3 car – has also been slotted in between the driver and roll-cage.

Ian Morgan, head of McLaren Automotive's motorsport division, said: "We’ve already got a very good GT3-based car, but we wanted to make it faster."

"We're very very proud of what we've achieved. I hope it delivers good satisfaction to the customer and a lot of fun."

CarAdvice has contacted McLaren Australia for comment on the prospect of local allocations and pricing. This story will be updated when more information becomes available.
