This new 650S it takes the place of the 12C Sprint in the brand's lineup, and should be the fastest 650S short of the GT3 racer. The thing is, the Sprint isn't technically a homologated racer, but it makes a great toy to show off at track days.
For the Sprint, the 3.8-liter twin-turbo V8 stays put, but McLaren optimizes the 650S' body for more downforce and better engine cooling. It also packs all sorts of track goodies like a competition fuel tank, larger radiator, racing-tuned suspension and 19-inch center-lock wheels. It also has all of the safety necessities for a day of doing laps like a roll cage, fire suppression and racing buckets. Of course, you might have known about all of that already, since the British brand revealed the Sprint just a few days ago, but you can check it live our gallery from Monterey.
