The ACRISS Car Code Algorithm
The ACRISS members had a requirement for a common rating system for rental cars across European markets, to ensure consistency of vehicle when customers rent cars from different suppliers.
Independent motoring consultancy Motoring Research was involved with the original development of this project in the 1990’s and took over the management and implementation of it in 2007. Motoring Research updates the database monthly, and acts as an independent consultant and arbiter for ACRISS discussions.
Each new model of car, to the engine and trim level, receives a point rating on a scale from zero to 10 (and occasionally higher). This numerical rating is derived from an algorithm that considers the car’s list price and its horsepower. CO2 and luggage capacity are also part of the consideration.
For each model of car the algorithm will produce a range of ratings, which determine the Car Category – for example, Compact for the VW Golf. In addition, if the rating for a particular model exceeds a pre-determined point for that Category, it will be moved into the Elite class. For example, a Golf 1.4 TSI S has a rating of 1.68 and is Compact. The Golf R with a rating of 6.14, is Compact Elite.
Similarly with SUVs and Passenger Vans (vehicles with six seats or more) the rating system also places emphasis on seating provision.
