McLaren MP4-12C

The McLaren MP4-12C is a sports car designed and manufactured by McLaren Automotive. The car's final design was unveiled on 8 September 2009, and it is set to be launched in 2011. The MP4-12C will feature a carbon fibre composite chassis, and will be powered by a mid-mounted McLaren M838T 3.8-litre V8 twin-turbo engine developing approximately 592 bhp (441 kW; 600 PS) and around 443 lb·ft (601 N·m) of torque. The car will make use of Formula 1-sourced technologies such as "brake steer[1] ", where the inside rear wheel is braked during fast cornering to reduce understeer. Power will be transmitted to the wheels through a 7-speed Seamless Shift dual-clutch gearbox equipped with "Pre-Cog", which allows the driver to pre-select the next gear by half-pulling the paddle shifter behind the steering wheel, which allows the transmission to execute faster gear changes.


As with the McLaren F1, carbon fibre (Carbon MonoCell) is used extensively in the vehicle to minimize weight. The MP4-12C will weigh only 1,300 kg (2,866 lb) dry. The chassis is based around an F1 style one-piece carbon fibre tub, weighing only 80 kg (176 lb).


The car is powered by a 3.8 litre twin-turbo V8 with a flat-plane crankshaft. The engine produces 592 bhp (441 kW; 600 PS) and 443 lb·ft (601 N·m) of torque. It has a redline of 8,500 rpm, with 80% of torque available at just 2,000 rpm. When they announced the car, McLaren claimed that their engine will have a higher horsepower to carbon dioxide emission ratio than any internal-combustion engine available at the time.Contrary to earlier speculation, this V8 is designed and developed by McLaren in partnership with Ricardo in Shoreham-by-Sea, West Sussex, dubbed M838T using twin turbos and driving the rear wheels through a seven-speed dual-clutch gearbox. The V8 has a dry sump and a flat-plane crank like a race engine, to lower the centre of gravity and allow a higher rev limit.


The car is rear-wheel drive using a seven-speed, dual-clutch gearbox made in Italy by Graziano


McLaren have stated the MP4-12C can accelerate from 0 to 200 km/h (124 mph) in 8.9 seconds. The car will have a top speed in excess of 322 km/h (200 mph) and will be able to brake from 200 km/h (124 mph) to a complete stop in under five seconds. Braking from 100 km/h (62 mph) to zero can be done in under 30 metres (98 ft), around seven car lengths. It is expected the 12C will complete the standing quarter mile in slightly less than 11 seconds.


The name of the new McLaren sports car is MP4-12C. 'MP4' has been the chassis designation for all McLaren Formula 1 cars since 1981. Since 1997, "MP4" has stood for McLaren Project 4 (from 1981 to 1996, when McLaren's title sponsor was Marlboro, the "M" stood for this), resulting from the merger of Ron Dennis' Project 4 organisation with McLaren. The '12' refers to McLaren's internal Vehicle Performance Index through which it rates key performance criteria both for competitors and for its own cars. The criteria combine power, weight, emissions, and aerodynamic efficiency. The coalition of all these values delivers an overall performance index that has been used as a benchmark throughout the car's development. The 'C' refers to Carbon, highlighting the unique application of carbon fibre technology to the future range of McLaren sports cars. The elements of this name represent everything that the McLaren MP4-12C stands for:

MP4-12C can also refer to the MP4-12 Formula 1 car that raced in the 1997 season. This car featured a second brake pedal discovered by photographers to counter understeer on the exit of the corners by selecting the inside rear wheel.


The car will have a conventional two side-by-side seating arrangement, unlike its predecessor the McLaren F1 which featured an irregular three seat formation (front center, two behind either side).
Interior trim and materials can be specified in asymmetric configuration - known as "Driver Zone"

Sports car racing

In December 2010 McLaren announced that they were to produce a small amount of MP4-12C cars, in order for them to be used in the GT3 category. McLaren stated that they will provide maintenance for the cars, and will begin racing in 2012 with the CRS Racing team. The MP4-12C will be the first car to compete in sportscar racing for the company, since the McLaren F1


n January 2011 TAG Heuer announced a new watch to be sold at McLaren dealers and at their website. The TAG Heuer Carrera MP4-12C was designed by TAG Heuer in conjunction with the designers of the McLaren car
