"Game Informer: Does TOCA Race Driver 2 feature a new physics engine?
Matthew White: The game features a whole new physics engine for the handling, and the car is under pure physics. Not a central pivotal point, or any pivotal points on the car, so when you drive the car around you feel the weight shift as it goes around corners, and when the car accelerates and decelerates.
GI: Did you guys take all these cars out and test them on tracks to get a feel for the physics?
MW: Yeah, sure. What we did was start out with a test bed car of a physics base, and each car in the game has got a massive database that goes along with the car for us to program all the cars. The database consists of technical information about the car. Things like technical specifications of the engine, the engine displacement and where it sits on the car, torque. But then it also goes into more technical things like how stiff the body is, how much ride is on the suspension arm, every detail. We get that information from the manufacturers. We then put the car together. The car models are based on CAD data from the manufacturer, which we then turn into polygons, and then put them in the game engine. Each component of the car is separately modeled. All the wings, the body, and the doors, so they can all be deformed when they have an accident. And we’re running a race with 20 cars all with damage, so you can damage all the AI cars."
