Ford YPF will switch to the new shape Focus, and former Toyota driver Norberto Fontana will make it a three car line-up for the 2010 season.
The team won the last race of 2009, thanks to Ponce De León, and are looking to carry that momentum in to 2010, despite the challenge of adapting to a new car.
The signing of 2002 champion Fontana, gives the team a three champion strong line-up for the new season.
Gabriel Ponce De León, three times a champion with the team, with which he has driven for since 1999, said:
"Firstly I'm happy to be for another year in the team. We have a new model and we have high expectations of its performance."
