McLaren today announced performance estimates for its new 650S supercar that will debut publicly next week at the 2014 Geneva auto show. The McLaren 650S will accelerate to 62 mph in 3.0 seconds, complete a standing quarter-mile in 10.5 seconds at 139 mph, and top out at 207 mph.
The McLaren 650S slots in between the existing, 616-hp 12C and the 903-hp P1 in the British company’s lineup. Like both of those cars, the McLaren 650S uses a carbon-fiber monocoque with aluminum front and rear structural frames. Power comes from a twin-turbocharged 3.8-liter V-8 engine rated for 641 hp (or 650 PS, hence the car’s name) and 500 lb-ft of torque, and a seven-speed dual-clutch automatic transmits motive force to the 20-inch rear Pirelli P-Zero Corsa tires. The fact that the car only weighs a claimed 2932 pounds dry helps enable such impressive acceleration times.
