McLaren 720S GT3X track-only special revealed


McLaren customers looking for something even hotter can now get a taste of the brand’s race-ready machinery with this, the 720S GT3X – a track-only model doesn’t have to conform to any rules or regulations, making it the most extreme version of the 720S yet.

"

Sitting above the 765LT track car, the 720S GT3X is the new range topper in McLaren’s ‘Supercars’ series of models, previously known as the Super Series before the line-up was rejigged recently with the launch of McLaren’s first plug-in hybrid, the Artura sports car.

The car has been developed by McLaren’s motorsport arm and uses a tuned version of the 720S’s 4.0-litre twin-turbo V8. The 720S GT3 runs to FIA GT3 regulations, but free from the restrictions of racing – and thanks to a lack of air restrictors and a pair of larger turbochargers, plus bigger manifolds and blueprinted cylinder heads – it produces 530kW.

There’s a push-to-pass button that adds an extra 21kW on demand as well, taking its total output to 550kW, or around 150kW more than the regular GT3 racing car.

The GT3X features a revised cooling system to cope with the extra power, while the car’s brakes have also been updated. It features a very similar aerodynamic package to the GT3, with front dive planes and a huge rear wing, with the package balanced for the GT3X.

The car’s suspension system is carried across from the regular GT3 and, although unconfirmed, we’d expect the X to feature a similar electronics package as the racer, offering traction control and ABS.

“We’ve already got a very good GT3-based car,” said Ian Morgan, Director of Motorsport McLaren Automotive. “We wanted to make it faster, so [there’s] more power, more acceleration, better braking and overall lap times considerably faster than the GT3.”

The chassis is the same MonoCage II carbon-fibre tub as used by the 720S road car and GT3 racer, while the interior is as stripped out and spartan as you’d expect from a track car. The GT3X also boasts a revised roll cage allowing space for a passenger seat.

This isn’t McLaren’s first foray into this area of the track day special market as, free from the rules of racing, the British brand embarked on a similar transformation of its MP4-12C GT3 competitor into the MP4-12C Can-Am back in 2012.

A limited production run of 30 cars, the Can-Am roughly AUD$670,000 at the time. Although McLaren hasn’t yet revealed pricing for the new GT3X – it’s simply asking interested parties to “register interest” currently, we know the 720S GT3 costs AUD$785,000, so an increase over this seems likely.
