SCORE Class 5

[5] Originally, and for many years, engines were required to be 4 cylinder VW air or water cooled engines, other main manufacturer of these was Porsche, a company closely tied to Volkswagen through shared design and heritage.

By the mid 2010s these large displacement air-cooled VW-type engines had become difficult and expensive to acquire and maintain, and a number of racers active in the class began the process of working to enlarge the list of available engines to keep the class alive and reduce costs for those competing it.

As a result of these discussions and negotiations a decision was made to allow any production based 4 cylinder engine of 2500cc or less to be used in the class.

A Class 5 Unlimited buggy built around a Subaru boxer 4-cylinder motor has been successful in a number of high-profile races, for instance.

Sheet metal front and rear firewalls are required and attached to the roll cage.
