The car, which will be renamed the C3 Rally2 in line with rallying’s new pyramid, will boast new engine software designed to improve getaway from stage starts. This will be homologated early in January.
Further upgrades in the first quarter of the year include a new front apron with revised aerodynamics, a new front differential rail providing a wider range of settings and an adjustable brake distribution pedal offering drivers greater comfort.
Other improvements include new engine brackets, rear toe brackets and exhaust manifolds to increase their service life.
The upgrades follow work in the last couple of seasons on suspension set-up in both asphalt and gravel trim and a new rear sub-frame to improve stability under braking.
Mads Østberg steered the C3 to the WRC world title at ACI Rally Monza last weekend while Marco Bulacia finished second in the WRC 3 standings.
Citroën’s aim is to improve the car in terms of performance, running costs and driveability and C3 Rally2 technical director Jean-François Grandclaudon said the process was focused on evolution.
“There is no need for a revolution on the C3 Rally2 in 2021. We are going to build on the excellent foundation we have, which is both robust and quick, to try and improve it where we can.

“Since its introduction in 2017, we have worked constantly and racked up a lot of miles on the road, enabling us to offer our customers an increasingly fast car, suited to all types of driver and with controlled running costs.
“This season, even more work was done with our two development drivers, Mads Østberg on gravel and Yoann Bonato on Tarmac. Over the last two years, the car has changed a lot, especially with a number of components that have not needed homologation and our efforts have now paid off with national and world titles claimed this year in major championships.”
Østberg has not yet finalised his 2021 plans but admitted that continuing with Citroën was an attractive option.
“Of course, the goal has to be to make it back to a factory World Rally Car. But at the same time, staying with Citroën is definitely something interesting for me,” said the Norwegian.
“It would be nice to have the chance to finish this job and compete in a car which I have developed. And it would be nice to have a car that is suiting me perfectly and the best car I’ve had so far.
“It’s been a challenge to make this car over the last two years, but I feel we have really come a long way. When I started out, it was not an easy car to drive and now I think we have really one of the best R5 cars out there.”
