ACRISS – Association of Car Rental Industry System Standards

ACRISS was formed in 1989 by Avis, Budget, Europcar and Hertz. This was reconstituted as a European Economic Interest Grouping (EEIG) in 1992. It’s role is based on various ongoing objectives. Many of these are based on car rental industry standards including the Global Distributions Systems (GDS), used as an interface between Travel Agents and the Car Rental Companies. The key role of Acriss is to develop standards, to avoid misleading information when making a car rental booking online or via any electronic means.


How does it work?

To help you make a choose between all the cars Hertz offers, we work with the four letter ACRISS system (Association of Car Rental Industry System Standards):

1st character defines the vehicle category – based on size, cost, power and luxury factor.

2nd character defines the vehicle type – chassis type (van, SUV, wagon, convertible).

3rd character defines the transmission and drive – automatic / manual & 2WD / 4WD / AWD.

4th character defines the fuel type (petrol / diesel / hybrid…) and whether the car is air-conditioned.


The characteristics defined in the ACRISS code are guaranteed, although we cannot guarantee aspects such as the brand or colour (with the exception of "collection cars").

2nd Character in Germany, character X has an additional meaning. It indicates a guaranteed built-in Navigation system.
