World Series by Renault
The team were formed in 2007 and was headed by Barry Walsh. He enlisted 2 ex McLaren personnel, Jonny Ostrowski and Colin Morgan to set up and run the team in the 2007 British Formula Three Championship. At the end of the year they joined forces with the French outfit Signature-Plus, run by Philippe Sinault to create Ultimate Signature, to run in the World Series by Renault in 2008.
The team had considerable financial backing from the Angolan oil company Sonangol, who have helped to create the Ultimate Motorsport Academy, which aims to take young drivers from karting up to Formula One, passing through various formulae such as Formula BMW, Formula Three and World Series by Renault.
The team began the season with two Brazilian drivers, long-time Formula Three racer Fabio Carbone and Claudio Cantelli, who graduated from the International Formula Master series. After a slow start to the season, which saw the team take one point from the first three rounds, Cantelli was replaced by Argentine Esteban Guerrieri, who was promoted from the Ultimate Motorsport British Formula Three team.
At the fifth round of the season in Hungary, Carbone took the team's first podium position with third place in the sprint race, and the following day he won their first race after starting from Pole position. Carbone took two further victories at the Nürburgring and Estoril to finish third in the standings behind Julien Jousse and champion Giedo van der Garde.
After starting the feature race at Le Mans on pole, Guerrieri finished in third place to claim his first podium position before going on to win the final race of the season at Barcelona. He finished eighth in the championship despite missing the first five races of the season.
After securing eight podiums over the course of the year, Ultimate Signature finished their début season in a superb second place in the Teams' championship.
For the 2009 the team signed Spanish driver Miguel Molina and British driver Greg Mansell son of former Formula One world champion, Nigel Mansell, Molina scored 3 podium finishes during the season, while Mansell scored only 4 points. Just before the Nürburgring rounds, the team lost its Sonangol backing and Mansell also decided to leave the team, and as a result the team were forced to withdraw from the Championship.
