The 650S may look like a face-lifted 12C, but there’s a lot more to it: The revised styling pays tribute to the P1 hybrid, the body tub is lighter, and about 25 percent of the parts are new. The heart of the car (and the name) is the 650-PS (641-hp) 3.8-liter twin-turbo V-8. Mated to a seven-speed dual-clutch automatic, the 650S can hit 60 mph in less than 3 seconds. There’s also a Spider version. For more power, there’s the 675LT, which makes 666 hp and hits 60 mph in a claimed 2.9 seconds.
The 650S shares the MP4-12C's Carbon fiber reinforced polymer chassis, and is powered by the same McLaren M838T engine 3.8-litre V8, twin-turbo engine, but now developing 641 bhp (478 kW; 650 PS) and 500 lb·ft (680 N·m) of torque. Power is transmitted to the wheels through a seven-speed near instantaneous shift dual clutch gearbox.
