Esteban Guerrieri is delighted to be moving back up the motorsport ladder after landing a drive with Ultimate Signature in the World Series by Renault.

Although still only 23-years-old, the 2003 Formula Renault Champion's career has been on something of a downturn since competing in Formula 3000 in 2004, having performed in Formula 3 Euroseries and, most recently, in the British Formula 3 Championship.

However, having helped establish Ultimate Motorsport - with their Mygale chassis - as frontrunners through 2007 and at the beginning of this year, the Argentine has now earned the chance to compete in the World Series for the remainder of the season.

Joining Fabio Carbone in the Anglo-French set-up, Guerrieri is excited to be making his debut on British soil at Silverstone this weekend.

"It is a step up for me for sure and it is really good for me to be here with Ultimate too," Guerrieri told Radio. "I am learning how to drive a bigger car with power in it, but we have to see how the rest of the weekend goes.

"It is a good thing to be moving up with Ultimate. The team is at the same base so we still see each other every day, but this is a new project and it is still growing. It is good to be here though having got good results in F3, so I am really looking forward to working with the team."

Although not his first time in the World Series having completed a one-off outing for Fortec Motorsport last season, it is still Guerrieri's maiden outing in the new car. So far, the weekend has gone better than his 21st practice placing suggests.

"It has been tough today because we haven't fitted any tyres onto the car, but we are going to change the car for qualifying and go for it. I have a fast team-mate, which is good for reference too.

"It is always important to aim high and ideally I would like to be in the Superpole session this weekend, but I am looking to my team-mate as a reference too. I want to set short goals and go for them as quickly as possible and then if a win or a podium comes then that will be even better."
