Voici la nouvelle Corvette C8 !

2020 Chevrolet Corvette Stingray

Chevrolet  dévoilé hier la nouvelle version de sa sportive phare.

Innovation majeure, cette version abandonne le moteur en position avant, pour un engin placé en position centrale arrière.

Côté moteur, le bloc est toujours un V8, dont la cylindrée de 6,2 litres ne change pas par rapport à la C7.

Voici quelques caractéristiques, en attendant d’autres informations sur ce modèle qui devrait être disponible courant 2020.
