Maserati GranTurismo MC breaks cover

Article by Christian Andrei, on August 29, 2010

The new Maserati GranTurismo MC racecar, which has been developed for competition in the FIA GT4 class and in several other GT4 European Cup races in the latter part of 2009, has been revealed.

It is derivative of the GranTurismo MC Concept which was introduced in Monza last September and is patterned on the electro-actuated gearbox system-equipped GrandTurismo S road version.

Not much is known about the car except that it is powered by the GranTurismo's 4.7-liter V8 powerplant and comes with a double cone racing air filter, high-flow exhaust with removable catalysts and a full carbon fiber body.

According to the carmaker the car comes with a power-to-weight ratio of less than 3.4kg/hp (4.6g/kW) and a curb weight of under 1,400kg.

The car was deliberately chosen with GT4 traits because this is the class with the closest connection to factory versions, and also the response to a niche of GranTurismo road car owners who are looking for a racing variant of their cars.

There will be a limited series GranTurismo manufactured for those who want to enter the 2010 GT4 European Cup and the national series which will hit the market beginning October 2009.

The initial price tag is 135,000 Euros excluding taxes, and the racecars will be vended directly via the company's racing division, the Maserati Corse. Eventually, Maserati will be launching its own one-make series, akin to the Super Trofeo series of Lamborghini, hoping to debut the car next year.

Press Release

Maserati GranTurismo MC Concept

Races have always been the most demanding test-bed for all cars. Traditionally, reliablity and performance are checked on the circuit. It is in races that new technologies and materials are tried out. And it is on the circuit that Maserati has decided to raise the much praised sporty verve of its Maserati GranTurmismo S to even higher levels to create the Maserati GranTurismo MC Concept.

Style

The changes the designers of the Maserati Style Centre have made to the GranTurismo S to create the racing model have improved its performance and above all its aerodynamic efficiency, without disturbing to its elegant, curvaceous line. The radiator grille of the Maserati GranTurismo MC Concept features two large air intakes - designed to increase the air flow to the engine and brakes - and an aerodynamic bottom trim. The front mudguards, with increased track, are also new, as is the engine hood with a dynamic air inlet and two additional air vents.

The car's profile has also been the subject of in-depth aerodynamic analysis, leading to the introduction of unusual side air vents, linked to the new miniskirts under the doors. What's more, the rear of the Maserati GranTurismo MC Concept has new-design fenders to accommodate the air vents and centrally located tailpipes. Last but not least, the boot spoiler is larger in size to increase the down force generated by the profile, thus compensating for the aerodynamic effect of the front spoiler.

Development

The Maserati GranTurismo MC Concept has been developed on the basis of the Maserati GranTurismo S, launched at the Geneva Motor Show on 6th of March 2008. The Maserati Racing Department engineers have made major improvements to reduce the car's weight while also engancing its performance. The mapping of the engine installed on the Maserati GranTurismo MC Concept has been revised to further increase performance without impairing reliability: the unit is now generating 330.9 kW (450 hp), with torque of 510 Nm at 4,750 rpm. The intake and exhaust systems have also been revised through the installation of a high-performance conical air filter combined with an exhaust system fitted with racing-type catalytic converters and silencers.

The suspension setting of the Maserati GranTurismo MC Concept, together with improved weight distribution and new single-string racing dumpers, plus new 12"x18" fron and 13"x18" rear wheels and slick tires, guarantee a striking increase in the car's dynamic performance compared to the Maserati GrantTurismo S.

The brake system has received an upgrade to withstand the stress typical of use on a track, whit adoption of larger discs and monobloc racing calipers.

The chassis has been significantly lightened and stiffened thanks to application of an integral welded roll cage, as required by the FIA regulations.

The coachwork, partially modified to meet new technical requirements, is in composite materials. The specific electrical system, the dedicated instrumentation including an integral data acquisition system, and the indispensable safety devices, complete the equipment of the Maserati GranTurismo MC Concept.
