I am observing that the different series GT4 of the whole world are taking a great boom with the arrival of the new models. Mc Laren, Aston Martin, Porsche, Audi, Mercedes, BMW, Ford, Chevrolet, Nissan, Ginetta, KTM, Sin, Panoz, Maserati have or will have GT4 Cars. The costs are many lower than the GT3. Tobias Moers AMG Chairman said: I think GT4 will be the new GT3. I would like to see Ferrari in this category, I know that the car of the Group here is the Maserati GT4, but Ferrari is different for me. The Ferrari GT4 could be the California, this is a render: Ferrari California GT Race Car Rendered - Diseno-art But I guess it should be easier to adapt the 488 Challenge to GT4 rules.
