Aha, thanks for the explanation. Sounds interesting.Yes, the Horizon games uses the same physics engine and cars as the Motorsport games with tweaks to make things more forgiving and arcade-like. With all assists off an old rear engine Porsche will still swap ends way easier than something like a WRX, front-drive cars will understeer heavily if you throw too much power at them, the big trucks have more inertia, etc. You can even bring up the telemetry data in the games just like in the Motorsport games to see exactly what the suspension, tires and engine are doing at any point.
A good example is the Beetle, which uses a swing axle rear suspension. In a swing axle the suspension attaches at the car's center so as the suspension unloads it introduces a ton on negative camber and on compression introduces a ton of positive camber, both of which are accurately modeled in the game.
