SIXT vehicle categories are classified using the internationally standardised ACRISS code (also known as CRS code). The four-letter code describes category, body type, transmission and fuel type — so you always know what to expect. All bookings are made by vehicle category, not by specific model.
How the ACRISS code works
The four letters each represent a different characteristic:
1st letter — Category (e.g. M = Mini, C = Compact, S = Standard, L = Luxury)
2nd letter — Body type (e.g. D = 4-door, F = SUV, V = Minibus, T = Convertible)
3rd letter — Transmission (M = Manual, A = Automatic, D = 4WD)
4th letter — Fuel type (R = Petrol/Diesel, H = Plug-in Hybrid, E = Electric, C = Electric Long-Range)
Example: CDMR = Compact · 4-door · Manual · Petrol/Diesel
Why book by category, not by model?
Each category includes several comparable models of similar size, equipment and price range. For example, a Compact booking may result in a VW Golf, Ford Focus or SEAT Leon — all equivalent vehicles within the same category.
Requesting a specific model
You can add a model preference in the comments field when booking — the branch will do its best to accommodate your request depending on fleet availability. There is no guarantee for a specific model, as the exact vehicle is typically assigned on the day of pick-up.

At SIXT, bookings are always made by vehicle category rather than a specific model. You can indicate a model preference when booking, and approximately 30 minutes before pick-up, you can select your specific vehicle in the SIXT app from the available models within your booked category.
