McLaren introduced the new 720S earlier this year at the Geneva International Motor Show as the successor to the 650S. It was probably inevitable then that a GT3 variant of the 720S would also debut a few years time, replacing the current 650S GT3. Now we have a first look at the British marque's latest racecar – the 720S GT3.

Though revealed in sketches, the 720S GT3 is still a few years off and is expected to enter competition by 2019. Development of the 650 GT3's sucessor, which debuted in 2014, is currently underway at McLaren's base in Woking, England. Testing is set to begin next year.

McLaren to introduce 720S GT3 race car in 2019

Much like it's predecessor, the McLaren says the 720S GT3 will use the same carbon fiber monocoque found on the road car. Powering it will be a race-prepared version of McLaren's 4.0-liter twin-turbo V8 M840T engine which will be mate to a six-speed sequential transmission. Power output will vary depending on the regulations the 720 GT3 will be running in.

As with most racing-variants of street cars, there is additional aero found on the 720S GT3. The sketches show a more aggressive carbon fiber front splitter coupled with small canards at the bumper corners. The hood and fenders also have more ducting, possibly to extract heat or help with the flow of air, together with a new carbon fiber side skirt. At the rear, there is a large rear diffuser and massive rear wing. The exhaust exit has also been revised to a twin center exit design.

Inside, expect the usual race car look on the 720S GT3 with a roll cage, racing harness and bucket seat to keep the driver safe.

Once launched, expect it to be competing in series such as the Pirelli World Challenge, the Blancpain GT Series and other GT3 series all over the world.
