Citroën homologated a range of new parts for the C3 at the start of last month, ensuring the Norwegian arrives in Zagreb with the best chance of hitting the ground running in his pursuit of back-to-back world titles.
Prior to competing on Croatia’s asphalt, Østberg will drive this weekend’s Therwoolin Boldogkö Rally, the opening round of the Hungarian Championship, with Tagai Racing Technology (TRT) World Rally Team which is running his 2021 campaigns in both series.
“We’ve worked hard on the C3,” said Østberg, “Really, I have been working on this car from scratch and to see how it’s working now is really positive. For this year I have two nice programmes and I’m going to be busy.
“WRC2 will be tough with guys like Andreas [Mikkelsen] in there. It’s going to be good fighting with him – especially now we have the car like we want it.”

The improvements to the C3 Rally2 come in the aero, the brakes and in the transmission.
“We have done some work on the front lip for the aero,” said Østberg. “That’s made a big difference in testing. For the transmission we have some new ramps in the differentials, then we’ve made some small changes in the brake system to get rid of some issues we had before.
“There’s some work on the software and geometry side as well – it’s a lot of small things, all of which will make a difference in the performance and the reliability.”
