Japanese manufacturers Subaru and Mitsubishi are both developing high performance versions of their existing Group N cars to enable them to compete on level terms with their Super 2000 rivals next year.
Work on the cars, based on the firms Impreza and Lancer models, began earlier this month after the FIA World Motor Sport Council gave the green light to a new ‘R4’specification.

An R4 kit, homologated by the current Group N manufacturers, should enhance the performance of the two-litre turbo cars, bringing them in line with the normally aspirated Super 2000s.
The R4 class could lead to Imprezas and Lancers competing alongside Super 2000 cars in the 2011 SWRC, and should also give the turbo cars a boost in national rallies where they already compete in the same category as the S2000s.
