Citroen has confirmed it will return to the World Rally Championship in 2007 after taking a one-year sabbatical.
Sebastien Loeb and Citroen won their second succesive title in 2005
The French manufacturer and Peugeot are withdrawing from the series at the end of this season because of high costs.
But Citroen says it will return after the International Automobile Federation confirmed cost-cutting measures and a radical shake-up to the race calendar.
The team added that world champion Sebastien Loeb would be able to compete next year in a privately-entered car.
"The decision to return was taken very quickly," said team boss Guy Frequelin, whose team are heading for a third straight constructors title this year.
"The new regulations allow us to meet our budget targets. There is no longer anything standing in the way of our return to the sport."
Citroen said 2006 would be a year of transition, with two-time world champion Loeb in a private team while they revived their C4 car development programme.
"Loeb will drive for a private team in 2006 and will have a Citroen wheel the next season. In the meantime, he will help us to develop the new C4," Frequelin said.
