What is GT4?
The Blancpain GT Series uses state-of-the-art GT3 cars, putting out around 500 horsepower each. Naturally, all those horses take some getting used to, which is why there’s a formula that slots in immediately below it: a bit like Formula 2 compared to Formula 1®.
The GT4 cars tend to look very similar to the GT3 cars, but performance is slightly lower, in order to provide a natural career ladder towards the top of the sport.
So far, 15 different cars have been homologated for use in the GT4 category, from some of the prestige and premium manufacturers seen in GT3, but also from other manufacturers who produce competition cars only for GT4.
These often have a long motorsport heritage of their own: for example, Lotus – one of the most evocative names in circuit racing – which has homologated the Evora GT4.
Ginetta is another manufacturer that makes cars only for GT4. Equally, there are some models that are bespoke to GT4 competition: Porsche is of course represented in GT3 with the iconic 911, but the Cayman model is unique to GT4.
On the other end of the scale, GT4 competition has also allowed new manufacturers to make their first steps into motorsport. Austrian manufacturer KTM has had huge success with cross country motorbikes but has only been producing track day cars recently, with the launch of its innovative X Bow. Homologating a GT4 example has proved to be the ideal method to promote it. In keeping with the philosophy of the series – and of Pirelli – GT4 has proved to be a perfect way of developing young drivers as well. Because of that, the Pirelli Junior Cup has been introduced this year, to reward drivers aged between 16 and 26.
