Unlike the requirements for the preceding Group A cars, manufacturers were no longer required to build "homologation specials" in order to meet approval. The base model did not need to have all the characteristics of the WRC car, as evidenced from cars such the Peugeot 206, 307, Citroën Xsara, and Škoda Fabia, which during this period had no road car variant with a turbocharged petrol engine or four-wheel-drive. One of the requirements was a minimum length of 4000 mm; the standard Peugeot 206 had an overall length of 3835 mm so Peugeot had to produce at least 2500 units featuring extended bumpers to comply with the required dimensions.
