Will Stevens will join the Manor team in the upcoming World Endurance Championship season, the squad announced on Monday.
Stevens drove for Manor in Formula 1 last year, when the team was run by John Booth and Graeme Lowdon, who left the squad at the end of last year.
Booth and Lowdon announced its team would join the LMP2 category in the WEC earlier this year, fielding a Nissan-powered Oreca chassis.
"The opportunity to continue my relationship with Graeme and John was one that I was very pleased to accept. It gives me a great chance to explore endurance racing, be competitive and go racing with people I enjoyed working with last year so I’m looking forward to it," said Stevens.
"My objective is to have a number of top level career choices going forward, and to be able to gain experience in endurance racing will hopefully open up my career prospects.
"I want to keep very busy, enjoy my racing and do some winning and I’m confident that by working again with Manor in WEC I’ll achieve all of those things."
Manor has also revealed it will field a second car in the WEC this season.
The team's programme includes the Le Mans 24 Hours.
Manor had only announced Briton Tor Graves for its driver line-up so far.
Stevens was one of the candidates for a Manor Racing seat in Formula 1, but he lost out to Indonesian Rio Haryanto.
