The McLaren 650S is a British sports car designed and manufactured by McLaren Automotive. It was announced in February 2014 as a new model, but based on the existing McLaren MP4-12C with 25% new parts, and was formally unveiled at the 2014 Geneva Motor Show.
The 650S shares the MP4-12C's carbon-fiber-reinforced polymer chassis, and is powered by the same McLaren M838T 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.
The 650S has a claimed top speed of 333 km/h (207 mph), and can accelerate from 0–100 km/h (0–62 mph) in 3.0 seconds and from 0–200 km/h (0–124 mph) in 8.4 seconds.
In June 2014, McLaren announced that they would produce a GT3 version of the 650S, either as a new car or as an upgrade for the existing 12C GT3 – which will contest GT3 championships from 2015 onwards.
Changes to the car from the road car includes a new 6-speed sequential motorsport gearbox, 380 mm ventilated brake discs with six-piston calipers at the front and four-piston units at the rear, a 52 mm wider track, revised suspension geometry, and upgraded components. It is further distinguished from the road car by larger air intakes and front splitter, and carbon fibre air intakes and a new rear wing.
The 3.8-litre McLaren V8 twin-turbo engine, also used in the 12C-GT3, produces 493 bhp (368 kW; 500 PS), and includes a new ECU to improve turbo boost and gearshifts. The power output is lower than the road going 650S’s due to homologation.
