SIXT’s rental car fleet includes a wide range from Standard and Premium vehicles to Commercial ones. For the sake of clarity and standardisation, these are divided into vehicle categories worldwide, according to the international standard ACRISS code (Association of Car Rental Industry Systems Standards). This includes various features, such as size, equipment, and engine. Since you book a car classification at Sixt, not a model, it is always ensured that your required equipment (air conditioning, automatic transmission, etc.) as well as features (seats, 5 doors, etc.) are taken into account when booking.
