The R4 project was motivated by the sad decline that the World Rally Championship has been going through. Once the most followed sport in the world, WRC is now dwindling. The answer: bring back ‘Group B’, the 80’s extreme rallying series. Wild cars and a free rule book, attracting top manufacturers, drivers, innovators - and more fans, just as in the 80s! The R4 is my vision for how modern Group B cars would look.
