SIXT wants to help you confidently choose the right rent a car by better understanding the ACRISS car rental code system. Knowing what car code letters mean provides you with a clearer idea of the vehicle class and characteristics of any model. Feel more certain that your car rental will meet your expectations and your requirements with our guide to the ACRISS rental car classification codes.
ACRISS (Association of Car Rental Industry Systems Standards) developed a car rental class code system that helps those interested in renting a car make a more informed decision. The system can be a useful guide when trying to select a rent a car best suited to your needs from the SIXT fleet.

How to Read ACRISS Car Rental Codes
Each code has four letters representing the different attributes of a vehicle.
- Vehicles are first assigned to a category according to their size (length and trunk volume).
- Secondly, premium OEM vehicles are separated into a dedicated "Elite" subcategory per size category.
- The body style, transmission, and engine type will be defined by the last three digits.
Addition:
- V as 4th letter indicates a car with 5+2 seats
- D as 3rd letter indicates a car with All-Wheel-Drive (AWD)
