McLaren is using the Pebble Beach Concours d’Elegance this week to show off a track-focused version of the 650S, dubbed the 650S Sprint.
The stripped-out race variant of the 650S has been fitted with a roll cage, carbon-fiber bucket seats with six-point harnesses, a fire extinguisher, and air conditioning to keep you cool on those hot days of lapping. The twin-turbo 3.8L V6 engine in the 650S Sprint is the same as the one found in the standard 650S. That means 641 horsepower and 500 pound-feet of torque. What has changed is the calibration for the engine and transmission, designed to improve track performance. There's also an enlarged radiator, new hood, and fuel cell.
