Martin Plowman will make his IndyCar return at Indianapolis Motor Speedway in May after securing a two-race deal to drive a second AJ Foyt Racing entry.
The 26-year-old Briton will drive the team's #41 car alongside Takuma Sato at the inaugural IndyCar race on the IMS road course, and will follow it up two weeks later with his first appearance at the Indy 500.
He was part of the OAK Racing line-up that won the P2 honours at Le Mans last year, and admitted that he was not sure he would get another chance to race single-seaters.
"Once my career took me to sports cars I was concerned that I would never get the chance to race at and win the Indy 500," Plowman said.
"Winning at Le Mans last year was an incredible feeling that can only be beaten by one day adding my face to the Borg Warner trophy.
"I've lived in Indianapolis for the last five years, and winning there is what I dream about."
Plowman made three IndyCar starts for Sam Schmidt Racing in 2011, achieving a best result of 11th at Baltimore. He has raced on the speedway at Indianapolis twice in Indy Lights, finishing fifth with Andretti Autosport in 2010.
He is scheduled to join the team for testing at Sebring on Wednesday.
