There is some really impressive realistic damage modelling including loss of tyres following a heavy impact with the barrier or a collision with another car, the front wing becoming detached which will affect the handling of your car until a pit stop has been made,
aerodynamic carbon fibre bodywork flying through the air in a variety of directions after a lesser impact which is not race ending but could affect the behaviour of your car, engine blowouts following a mechanical failure or too much mileage on the same engine and more besides.
