McLaren MP 4-12C 2012

With the best experience and outstanding team work the Engineers and designers at McLaren are currently developing several new and highly innovative sports cars to bring to the global market. The MP 4-12C is now in production signaling the beginning of the rebirth of a company that has not had a distinct production vehicle for over a decade. Its stunning performance and efficiency have caught the eyes of the automotive press since McLaren first began testing mules at their facility and now we get to see it in final form.

The MP 4-12C 2012 Specifications
The M838T engine was designed specifically for the 12C and has several unique features. It is a 3.8-liter twin-turbo V8 weighing only 439 lbs. The engine produced 592hp @7,000rpm and 443 lb-ft. of torque between 3,000 and 7,000rpm for the 2011 and 2012 model years. With the use of the company’s carbon-fiber structure and other lightweight components, such as an optional exhaust made from Inconel, the car achieves a stellar power-to-weight ratio of 455bhp/tonne. It’s a simple racing that low weight and high power are key ingredients to speed. The 12C will reach 60mph in 3.3 seconds and an even faster 3.1 seconds with the optional high-performance tire option. As this car will undoubtedly be compared to the McLaren F1 of the past, the new team made sure the top speed of the 12C would be formidable topping out at 205mph.
Vehicle dynamics technology including Brake Steer, ProActive Chassis Control and the unique McLaren Airbrake combine to offer sublime comfort in all driving conditions; and yet deliver race car performance and handling on track.

McLaren is a carbon pioneer. In 1981 McLaren gave a debut to a carbon fibre monocoque chassis in Formula 1 with the launch of the MP4/1 race car, and in 1992 the legendary McLaren F1 introduced the advanced composite technology to the world of road cars. It was natural then for McLaren Automotive engineers to apply its carbon expertise when developing the groundbreaking one-piece moulded chassis of the 12C. With the 12C designed originally as a convertible, its 75kg 'MonoCell' requires no additional strengthening for it to feature in the 12C Spider. The result is a sports car almost identical to its fixed roof equivalent in performance terms, and weighing only 40kg more with the addition of a convertible roof system.

The Retractable Hard Top of the 12C Spider is operated using a switch in the lower section of the centre console inside the cabin, taking less than 17 seconds to raise or lower. Unlike many other convertible models,the roof can be operated whilst the 12C Spider is moving at speeds of up to 30 kph (19mph).
