Alexander Rossi and Rio Haryanto will race for Caterham in this year's GP2 championship.

Rossi raced for Caterham in GP2 last season and won the feature race in Abu Dhabi.

He will continue to act as Caterham's reserve driver in Formula 1 outside of GP2 weekends.

"I am pleased to be back with Caterham Racing for 2014 fighting for a GP2 Championship," he said.

"As returning Caterham reserve driver my duties will continue with F1 outings, my role as simulator driver and on track reserve for non-GP2 weekends. This is the perfect development for my future F1 race drive as I play an important role in assisting the team develop its 2014 car, something that will be particularly important this year with the current technical changes."

"We have a fantastic chance to win the GP2 title in 2014, while the F1 team achieves its goals of moving forward. This is an important era for all of us, as the sport enters a new generation."

Haryanto raced for Addax in 2013 and claimed a podium at Silverstone.

"It is a great feeling to sign with Caterham Racing for my 2014 GP2 campaign. After such a successful post season test with the team in Abu Dhabi and the possible Formula One opportunities, this was the obvious choice for me," he said.

"I am also looking forward teaming up with Alexander Rossi. We are both strong Championship contenders and with our GP2 experience, we will work together to fight for both the team and driver Championships."

"My ultimate goal is to finish the season as high as possible in the 2014 GP2 Championship and give myself the best possible chance of a full time Formula One seat in 2015."
