To understand Porsche Cayman GT4’s true identity, simply look at it. The bodywork has been enriched by a series of aerodynamic elements to obtain maximum performance by providing air flows. The study on the aerodynamics was one of the points on whose German engineers they focused more. The front area has pointed shapes, like an arrow that feeds the air: a solution that ensures the car to always remain crushed on the ground. A further aerodynamic element is noticed on the front spoiler: a ruling that stretches towards the fender, thus optimizing the downforce. To reduce the turbulence, an Air Curtain system has been developed that allows the air penetrated in front of the wheels to exit through the wheel arches by minimizing interference to a minimum. The protagonist of the rear area is certainly the fixed wing with aluminum supports. It is an element obtained from the world of competitions and guarantees a very high traction not only in the curve, thanks to the downforce. The new rear diffuser generates an air flow on the rear underbody, offering a depression of 40% greater than the previous model.

At the beginning of 2012, the FJ Group shakes an agreement with the NASCAR which allows the championship to become part of the Nascar circuit and to become the European official series, however remaining an international series recognized by the Federation^[2]. By virtue of this agreement, the winner of the championship is invited to the Nascar Nights of Champions Gala which takes place at NASCAR Hall of Fame in Charlotte on North Carolina. The first pilot to participate was the Spanish Ander Vilarino, winner of the series in 2012^[3].

On 1 July 2013 the partnership with Whelen Engineering was announced, which leads the series to be renamed in Nascar Whelen Euro Series^[4]. In December 2017 the renewal of the partnership and the title was announced at least until 2024^[5].
