A growing body of research is being conducted all over the world to evaluate and compare the safety impacts of different car brands and vehicle types. This issue has also received a considerable attention among the safety experts in Iran, where the number of road fatalities is around 16500 lives per year. This study aims at indexing crash worthiness, crash aggressivity and total secondary safety of the 20 most prevalently used Passenger Car brands of Iranian fleet and different vehicle types (Buses, Minibuses, Light Trucks, Trucks, Pick-up Trucks, and Passenger Cars). For this purpose, the data pertaining to 1,360,415 crashes and 2,407,196 drivers involved in those crashes that occurred in Iran from 2009 to 2012 were used. Binomial Logistic Regression model was applied in order to define the above-mentioned indices based on driver’s injury severity level. The results showed that most of the domestic brands have a poorer performance than the foreign ones in all three indices. Furthermore, it was revealed that Kia and Suzuki have a better performance and Sepand and Pride have a poorer performance compared to the other brands. It was also unfolded that Buses are the best vehicle type. Our findings might also be integrated with the findings of other similar studies around the world. This could be helpful for car manufacturers both in Iran and across the world in order to benchmark the best performing car brand in vehicle safety domain and improve the designing of their own car brands.
