The McLaren 570S GT4 made its U.S. debut at Monterey Car Week, taking to the greenside rough at The Quail, A Motorsports Gathering. The 570S is one of the latest versions of the 570 range (which is gaining additional numbers and letters left and right) and it’s meant solely for the track, outfitted with all one needs for battle.

The 570S GT4 still uses the same 3.8-liter twin-turbocharged V8 M838TE engine connected to a seven-speed dual-clutch gearbox borrowed from the civilian-spec Sports Series, though it features a wider track front and back to house the larger wheels and Pirelli racing tires (which do come standard). Designed for privateer racing, the 570S GT4 offers reworked aerodynamics, including a redesigned front splitter, radiator exit ducts and a rear wing sitting on aluminum pylons. Those ducts are there to serve the additional high temperature radiator under the hood, while the changes on the inside include an FIA-approved roll cage, racing seats and an integrated fire extinguisher system.

“The launch of the Sports Series has broadened the McLaren brand to a new audience, introducing technologies to the sports-car market and to a new group of customers,” said  Mike Flewitt, chief executive officer, McLaren Automotive, during the 570S GT4’s announcement this March. “The introduction of the 570S GT4 is doing the same in the motorsport world, and will bring the opportunity to own and race a McLaren — previously limited to a very small number of people — to a much wider group.”

Developed with racing specialist CRS GT, the 570S GT4 already has a win to its name since debuting at Brands Hatch earlier this year. McLaren expects to start offering ready examples to customer teams next year.
