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 codes (created by the Association of Car Rental Industry Systems Standards) are used to categorise rental vehicles, depending on certain characteristics they have. It helps to cluster a set of similar cars, so that in the event a specific model is not available, we are able to offer you a similar vehicle from the same category. Here at SIXT we have a comprehensive set of categories, including compact / saloons, 4x4s / SUVs, people carriers, luxury cars and vans.

Composition of ACRISS Codes
The ACRISS Code consists of 4 letters - each defining a vehicle characteristic.
- 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.
Specification for EU:
Standard and Fullsize categories have same defining criteria, but all standard OEMs will be allocated to Standard and premium OEMs to Fullsize
Addition:
- V as 4th letter indicates a car with 5+2 seats
- D as 3rd letter indicates a car with All-Wheel-Drive (AWD)
