Expansion of World Rally Car: 2017-2021

The World Rally Car: 2017-2021 group is really slim with only 2 cars and missing really great ones like the Hyundai i20 Coupe WRC, the Citroen C3 WRC or the Toyota Yaris WRC (this one I guess is extra problematic due to Toyota..). Maybe the Citroen DS3 WRC could also be added given it is a bit between the two WRC groups in the game.
