What's the difference between GP2 and F 1?

To some extent, there is a great difference between the two cars, mainly in the performance of grip, because in F 1, in order to adapt to different types of track and weather conditions, the tire compound is very different. But comparing the similarities between GP2 and F 1 really surprised me. The centrifugal force is greater when driving F 1 racing car through fast corners, while the feeling of GP2 racing car passing through medium and slow corners and braking is very close to that of F 1 racing car.

GP2 is a competitive training ground, and all drivers use the same Renault engine and Della chassis. Therefore, for GP2 series, it is very appropriate to use the same brand of tires to decide the driver's championship. However, F 1 is a super single-seat competition. It is made up of different teams. They use different engines and their own chassis. In this case, a competitive tire manufacturer is more suitable.
