Ahead of testing today in Portugal, Renault unveiled its new 2009 challenger.

As previously reported, the R29 features sponsorship from French oil giant Total with the front and rear wing end-plates prominently displaying the brand.

Regular racers Fernando Alonso and Nelson Piquet posed with the new car as did Romain Grosjean who will be the team’s test and reserve driver this year. 2008 test driver Lucas di Grassi tested with Honda at the end of last year and is now rumoured to be looking to the IndyCar series for 2009.

After a strong second half to the 2008 season that saw Renault out-score the likes of Ferrari and McLaren, the team hope that Fernando Alonso will be able to challenge for regular race wins and the championship with the R29.
