The Audi S1 WRX was a rallycross car developed by Audi Sport for the FIA World Rallycross Championship between 2014 and 2019. It was fitted with a turbocharged engine producing around 600 hp, quattro all-wheel drive, and acceleration from 0 to 100 km/h in under two seconds. Following Audi's official withdrawal, it continued competing with private teams such as Monster Energy RX Cartel, achieving notable results including second place at Silverstone 2019 and Andreas Bakkerud's world vice-championship. The very car that raced at Silverstone, driven by Bakkerud, was used as the model by SCX for their reference U10319S300.
