McLaren's customer racing 720S gets taken to a new extreme.
If the regular McLaren 720S is somehow too tame for you, McLaren also offers a GT3 customer racing version that replaces the 650S GT3 and competes in GT3 championships in Europe, the US, and the Middle East. Now, McLaren has unveiled a new track-only version of the 720S based on the GT3 race car: meet the new McLaren 720S GT3X.
Free from the shackles of GT3 racing rules and regulations, the GT3X offers more power, faster acceleration, and better brakes than the standard 720S GT3. McLaren says these modifications will enable the 720S GT3X to achieve "considerably faster" lap times than the regular GT3 car.
McLaren hasn't released any performance specs to support this claim, but the standard 720S it's derived from is no slouch, capable of accelerating from 0-60 mph in 2.8 seconds and max out at 212 mph.
Like the GT3, the GT3X is powered by a hand-built 4.0-liter twin-turbocharged V8 uprated to produce 710 horsepower, an increase of 200 hp compared to the GT3 while matching the output of the 720S road car. An available "push-to-pass" can also increase the power output by up to 30 hp. This was achieved by installing bigger turbos and manifolds as well as a blueprinted cylinder head and an upgraded cooling system from the GT3 car to optimize the performance.
At its heart is the same lightweight carbon fiber MonoCage II monocoque chassis underpinning the 720S road car and GT3 racer. Visually, the GT3X features an enhanced version of the GT3 car's aero package with modifications including new dive planes on the front and a larger fixed rear wing. Coupled with the GT3 car's active suspension featuring adjustable dampers with coil-over springs, these modifications keep the car glued to the track.
Inside, the rollcage and interior design has been modified to allow room for an additional front seat to take a passenger along for the ride. In contrast, the 720S GT3 only has a single seat for the driver. Pricing for the McLaren 720S GT3X hasn't been confirmed but it will likely cost more than the standard GT3 car, which starts at $564,000.
