    Group GT3, known technically as Cup Grand Touring Cars and commonly referred to as simply GT3, is a set of regulations maintained by the Fédération Internationale de l'Automobile (FIA) for grand tourer racing cars designed for use in various series' throughout the world. The GT3 category was initially created in 2005 by the SRO Group as a third rung in the ladder of grand touring motorsport. The FIA launched its own series in 2006, the FIA GT3 European Championship. Since then, Group GT3 has expanded to become the de facto category for many national and international grand touring series, although some series modify the ruleset from the FIA standard. By 2013, nearly 20 automobile manufacturers have built or been represented with GT3 machines.

    Group GT3 allows for a wide variety of car types with almost no limit on engine sizes and configurations or chassis construction or layout. GT3 cars must be based on production road car models in mass production. Performance of all the Group GT3 cars are regulated, either by the GT Bureau of the FIA or by a series' specific ruling body, through a Balance of Performance that adjusts limits on horsepower, weight, engine management, and aerodynamics to prevent a single manufacturer from becoming dominant in the class. The cars in GT3 are designed to have a weight between 1200kg and 1300kg with horsepower between 500hp and 600hp. All cars have a very similar power to weight ratio. GT3 cars also have traction control, ABS and built in air jacks for quick pit stops.

    BMW M3 GT3
    The series version’s eight-cylinder engine with 4.0-litre capacity already produces 420bhp. The BMW P65 engine, which was derived from this unit and powers the BMW M3 GT, has been further improved within the regulations. The eight individual throttle valves receive their intake air via a system made of carbon fibre with load-charge optimised ram tubes. The mechanics have been adjusted to meet the extreme demands of GT and endurance racing: as a result, the BMW P65 has a steel crankshaft, forged skirt pistons, high-performance steel conrods and a dry sump lubrication system. This allows the engine to achieve 500bhp. Thanks to demand-controlled auxiliaries and cylinder cut-off, as used in the BMW EfficientDynamics technology package, the BMW M3 GT is redefining the boundaries of consumption.

    The functions of the BMW P65 engine are managed by an ECU408 electronic control unit, developed in-house by BMW Motorsport. This unit uses two high-performance micro-processors to control the individual cylinder injection and ignition, as well as the engine data memory system, among other things. The ECU408 monitors the “Quick Shift” function of the six-speed sequential gearbox on the BMW M3 GT, which suppresses the ignition when changing gear, thus allowing even faster gear changes. The compact transmission unit is positioned on the rear axle to allow optimal weight distribution. The drivers are assisted by a mechanical limited slip differential and traction control.

    RUF RGT-8 GT3

    The RGT 4.2 maintains a long tradition of Ruf supercars with its outrageous driving performance. Unveiled in 2000, the first RGT was characterised by its powerful, torquey normally-aspirated flat-six engine. With a significantly reduced all-up weight and sports-oriented suspension system, the RGT was an extremely impressive driving machine.Now, in 2015, the RGT remains true its original concept, though its external appearance is clearly more athletic. The wheel arches are more bulbous and the front facade presents huge round air intakes for more effective cooling. The chassis is reinforced by RUF's hallmark Integrated Roll Cage (IRC). Propulsion is provided by its virile 4.2-litre six-cylinder, normally-aspirated engine, developing 525bhp and 500Nm of torque, featuring dry sump lubrication with external oil tank. A proper driving machine for sure
