Williams reserve driver Felipe Nasr is targeting winning the GP2 title this season after confirming that he will continue to race for Carlin in the series.
Nasr made his GP2 debut in 2012 and finished in fourth place in last year's championship after switching to Carlin.
The Brazilian will dovetail his GP2 duties with his commitments in Formula 1 with Williams.
Nasr tested the Williams FW36 during the final pre-season test in Bahrain and is set to participate in five free practice sessions for the team.
"I’m really happy to be with Carlin this year, we had a tough fight on our hands last year and although we missed out on the championship through some bad luck and some difficult races, I think overall the season was very positive for us," he said.
"We work very well together and it’s a very easy relationship. This year I want to go one better and push hard to win the championship; with a strong team like Carlin, and the new rules in regards to the tyres I think we can do this.
"It’s also going to be a great year for me to be involved with Williams and learn from them. I’ll be attending every race this season with a strong attitude so can’t wait for everything to start."
GP2 testing begins in Abu Dhabi next week ahead of its season opener as a Formula 1 support race at the Bahrain Grand Prix.
