STATS19 vehicle records are augmented with DVLA data including date of first registration and codes specifying the vehicle’s make and model. Six types of car have been defined based on these codes. This report analyses the influence of car ‘type’ and registration year on the number of car occupant casualties, the basic measure of risk being the driver casualty rate per million car-years. Analyses deal mainly with the aggregated annual data from 1999-2003, a key set of analyses was updated to 2001-05. Statistical models separate the effects of car type and registration year on risk of injury in car-car collisions. The mean risk of death for the driver of the smallest type of car is 4 times the risk for the largest type, while the mean risk of death for a driver in collision with the largest type of car is over twice the risk when in collision with the smallest type. The mean risk of death for the driver of a 2000-03 car is less than half the risk for the driver of a 1988-91car, while the mean risk of death for a car driver in collision with a 2000-03 car is 46% greater than the risk when in collision with a 1988-91 car.
