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.
