...this could have been their entry. The Audi S1 Rallycross Supercar of Mattias Ekström, currently modified to the requirements of the Rally Legend event in San Marino next weekend.
And yes, it is the car that Ekström used when he won the World Rallycross Championship in 2016. Fellow Swede Robin Larsson used the same car to win the European and the Nordic Championships this year. A proper legend, that is.
