The McLaren MP4-12C, later known simply as the McLaren 12C, is a sports car designed and manufactured by McLaren Automotive. It is the first production car wholly designed and built by McLaren since the McLaren F1, which ended production in 1998. The car's final design was unveiled in September 2009, and was launched in mid-2011.
The MP4-12C features a carbon fibre composite chassis, and is powered by a mid-mounted McLaren M838T 3.8-litre V8, twin-turbo engine developing approximately 592 hp (441 kW; 600 PS) and around 443 lb·ft (601 N·m) of torque. The car makes use of Formula 1-sourced technologies such as "brake steer", where the inside rear wheel is braked during fast cornering to reduce understeer. Power is transmitted to the wheels through a seven-speed seamless shift dual-clutch gearbox.
The revised GT-R features an engine with revised mapping, changes to valve timing, larger inlets and a revised exhaust system which boosts rated power to 545 bhp and 612Nm of torque from 3200 to 6000rpm. Changes also include a new more rigid front strut bar made from carbon composite, larger front brake rotors, new lighter and stiffer wheels, and revised Dunlop tires. Cosmetic changes include a new front bumper with integrated LEDs. The front bumper improves cooling to the radiator and front brakes while reducing drag. A new rear diffuser improves downforce and also includes additional rear cooling ducts. The interior was revised to improve the quality. This new version is offered with a new HDD CARWINGS navigation system with enhanced entertainment features and USB port with iPod connectivity. The revised GT-R went on sale in Japan from mid November 2010 and February 2011 in Europe, North America and other regions
