Autosport.com reports that Ford was the first to announce its renewed commitment for the 2010 and 2011 seasons.
“I'm delighted to continue our partnership with Ford. The announcement is a further vote of confidence in M-Sport and displays the importance in which Ford holds the WRC," said Malcolm Wilson, boss of the M-Sport team which runs Ford’s cars in the series.
“Throughout 2010 and 2011 we expect to maintain Ford's significant presence in the WRC service park, both through the official 'works' team and via our customers."
Citroen’s agreement also covers 2010 and 2011.
“The WRC, where the costs remain contained, is an excellent promotional vehicle," said team principal Olivier Quesnel. “Citroen Racing is delighted by the trust that has been placed in us by Citroen’s board of directors and the PSA Group.
“We are currently working with our existing driver line-up to renew their contracts. I am confident that Sebastien Loeb and Dani Sordo will be continuing their adventure with Citroen Racing into the future."
Citroen is currently in talks to renew the contract of star driver Sebastien Loeb, whose deal runs out at the end of this year.
