Caterham ends Arden FR3.5 tie-up

The Caterham Formula 1 team's junior program has ceased its involvement with Arden's Formula Renault 3.5 squad for the 2014 season.

The two teams entered the Renault-backed series with a joint effort for the 2012 season, with one car for Red Bull juniors Lewis Williamson and Antonio Felix da Costa, and one for Caterham protege Alexander Rossi. However, Caterham did not place one of its own drivers in the team for 2013, meaning Pietro Fantin was able to take the second seat alongside Red Bull-backed da Costa.

Caterham, which has had its own GP2 team since 2011, has now decided it does not need to have an involvement in FR3.5. That means Caterham no longer has a shareholding in Arden's FR3.5 effort, so the team will be renamed Arden Motorsport in 2014.

The name change for Arden is the most significant alteration on the entry list for FR3.5 in 2014, as Renault Sport confirmed on Friday that all 13 teams from this season will remain in the championship. The only other change is the removal of the P1 name from Strakka Racing, which took over the team at the start of the 2013 campaign.
