Dynamic world debut : McLaren MP4-12C GT3

2011 McLaren MP4-12C GT3

The first McLaren car built for racing outside of Formula 1 since the McLaren F1 GTR will make its public dynamic world debut at the 2011 Goodwood Festival of Speed, held from 30 June-03 July. The new GT3 car, based on McLaren’s MP4-12C high-performance road car, will appear in its revised form, honed during a recent intense period of development.


New components designed to optimise the car’s aerodynamic performance include a front radiator, which increases the maximum ambient temperature at which the car can run, along with a new gearbox cooler mounted on the rear Aerodeck. These features complete an aerodynamics package incorporating a new front splitter, door blade, rear wing, diffuser and louvres in the front fenders, all of which is produced entirely from carbon fibre by McLaren Racing, following design input from McLaren Automotive.

The 12C GT3 is being developed by the recently established McLaren GT. Led by McLaren Group CEO Martin Whitmarsh and CRS Racing Team Principal Andrew Kirkaldy, McLaren GT is spending the 2011 race season developing the 12C GT3 before delivering 20 cars to privateer teams for GT3 racing in Europe in 2012.

Like the 12C road car, the MP4-12C GT3 features a unique one-piece carbon fibre chassis, the ‘MonoCell’. McLaren introduced a carbon fibre monocoque to Formula 1 in 1981, and the 12C GT3 will feature several other Formula 1-derived technologies. The 12C GT3 will be supplied with the same steering wheel design used by Lewis Hamilton in his MP4-24 Formula 1 car. Formula 1 suppliers past and present including Akebono, Mobil 1, McLaren Electronic Systems, Ricardo and Michelin are working with McLaren GT to create a race car specification technologically superior to the GT3 competition in 2012.

Since the 12C GT3 was unveiled to the media and prospective team owners in May 2011, McLaren GT has tested its new car at a mixture of proving grounds and FIA approved circuits across Europe. This development phase is an opportunity for McLaren GT to optimise the technical specification and durability of the 12C GT3.

Andrew Kirkaldy from McLaren GT said: “The reaction to the 12C GT3 at the circuits we have visited has been phenomenal. I can’t wait to see how it goes down at Goodwood this weekend.

“CRS Racing was clearly excited to be confirmed as partner in this project as we were only too aware of McLaren’s short, but unbelievable GT history with the F1. But the anticipation amongst circuit owners and race teams to McLaren’s return to GT racing has still surprised us. I’m delighted that we have the opportunity to drive the 12C GT3 up the hill at Goodwood and raise the interest even further.”

Confirmed drivers of the GT3 car for the 2011 Goodwood Festival of Speed weekend are Andrew Kirkaldy, 2010 Vodafone McLaren Mercedes test driver Oliver Turvey, and McLaren Automotive Chief Test Driver Chris Goodwin.

2011 McLaren MP4-26 F1

McLaren's new car which will be held in the 2011 season Formula 1 competition was launched on Friday, February 4, 2011 in Berlin, Germany. The car, named the McLaren MP4-26 that still keep many puzzles associated with advanced technology. McLaren MP4-26 was designed with a shape that does not seem "arrogant". McLaren MP4-26 Nose flat course, does not look like RB7 profile, the new Red Bull Racing car.

McLaren MP4-26 Nose only seemed longer than the old model. Significant differences emerged only in the side air vents in the form of L so that the letter of the MP4-26 profiled U. "Please remember, you all have not seen the actual contents of this car. There are many interesting side of this car that has not been shown. We have deliberately concealed many aspects of this car from the media and of course the competitors," said Martin Withmarsh, McLaren boss.

“Formula 1 at its core is a sustainable development. We’re just going to do official tests next week. There will be some fantastic innovation that will be done after this, “added Withmarsh.
McLaren MP4-26 that was launched is indeed likely to be a mock-up, the car was not lauched in the circuit because the engine on a model that was launched is made of plastic. The car was also assembled in conjunction with the introduction to the public. McLaren’s new MP4-26 will progress to the second official test of Formula 1, which will be held February 10 to 13 in Jerez, Spain.

2011 McLaren MP4-12C GT3

McLaren today confirmed his plans to bring back the name of McLaren for the GT sports car racing. From 2012, McLaren Racing and CRS will provide and support a number of GT3 racing car based on the car McLaren MP4-12C high-performance sport for Europe-based privateers.

15 years since the famous McLaren F1 GTR won the famous 24 Heures du Mans in the world (Le Mans) on debut, and 12 years since six 'Longtails' last raced at Le Mans, and CRS McLaren Racing, a successful and experienced English-racing team based, began working development aimed at changing the way cars 12C to-win sports car racing GT3. As part of program development, and CRS McLaren Racing will compete in a number of European GT races in 2011.

With a revolutionary lightweight 12C one-piece molded carbon chassis (the 'MonoCell'), high levels of downforce and aerodynamic performance, and focus on form and function, a 12C should prove to be a great platform to develop racing cars, as well as visual setting pulse race track racing in Europe.

Martin Whitmarsh, Vodafone McLaren Mercedes Team Principal said: ‘Racing is in our blood – it was natural to develop a GT3 car alongside the 12C road car. We have a legendary history in global motorsport, including GT racing, and we aim to maintain that reputation with this GT3 programme, and any future sports car projects that may evolve.

CRS Racing will build, sell and support the GT3 cars 12C in close collaboration with McLaren. Leicestershire-based racing team has a strong pedigree in GT racing in Le Mans Series, FIA GT Championship, the International GT Open and the British GT Championship. CRS also run two successful single-seater team: in Formula Renault UK Championship and as Atech CRS in Series GP3.
