The new Ekris M4 GT4 has been specially developed with the needs of racers in mind. We have used all the experience gained during our more than 20 years of racing history. We have worked on this development in close collaboration with respected partners, making use of our combined knowledge. We received support from the SRO (Stéphane Ratel Organisation), organiser of highly-respected GT racing series like the GT4 European Series.

The BMW M4 provides the ideal platform on which to develop a racing car. It is powered by a three litre six-in-line Twin Power Turbo engine that delivers 431hp. We have expanded on this ground-breaking technology by modifying a large number of parts to ensure that the vehicle is track-ready. This includes, among other things, an adjustable race chassis, an exhaust system equipped with flow racing catalysts and the optimisation of the entire electronics system. The car has also been aerodynamically optimised to meet the demands of the GT4 rulebook, being equipped with monoblock brake callipers and supported by a race ABS system.

The M4 GT4 is of course also equipped with a number of safety precautions. This includes an approved roll cage, safety belts and a race seat, that all meet the latest safety standards.



Ekris Motorsport has developed this new M4 GT4 to compete in a variety of national and international champion­ships. The 125-litre fuel tank makes it not only suitable for national and international sprint championships, but also for participation in endurance racing like the Creventic 24H Series and the German VLN championship.
