Lead Programmer Dénes Nagymáthé explains: "Every car has its own damage characteristics and weaknesses produced by its shape, mass, and physical structure. Using vertex-based chassis and part deformation, every impact produces a unique result, as mesh deformation is calculated real-time based on the actual collision impulse vector. Damaged doors and hoods are flapping and falling down just like the bumpers, wheels or other parts. Impacts on wheels can deform the geometry of the suspension, making the wheel wobble, get nipped or stuck, pulling the entire car to one side." "Another nice aspect of the damage system, is the particle system with its varied effects. Sparks fly all around as the car scrapes the barriers, and even windscreens and windows can be blown into tiny pieces. This looks especially nice when played back in slow motion replay. In addition you will be able to hear and feel every jump and bump as the suspension and the chassis creaks and squeaks".
