Sebastien Ogier AND Dani Sordo will be racing this weekend in Autocross (Its like Formula 1 but on Dirt?...Tho its in the French Championship, not on the FIA EuroAX). Its very similar to rallycross but with open wheel cars. Basically same power as the European RX cars (not necessarely on HP, but because the cars are very light). Seb will be racing with Florent Tafani's car. This car WON the FIA EuroAX championship in 2021. Dani will be using Axel Teygnier's car. BOTH are from a Czech brand called AlfaRacing. The team running them is called Evo Sprint.
I believe none of the cars will be RedBull branded. Neither are on Toyota and Hyundai engines. I THINK Sordo's car have Honda engines but I cant know for sure.
