Ultimate Motorsport has revealed that Esteban Guerrieri will make a one-off return with his former team for the F3 Masters at Zolder this weekend.
The Argentine racer moved up to the Renault World Series mid-way through the season with the sister Ultimate-Signature team but will return to his former mount for the non-championship F3 event alongside Michael Devaney and Ricardo Teixeira.
"We're all looking forward to Zolder," team manager Andy Richardson said. "We know the challenge that faces the British teams at the Masters: it's well-documented that the tyre situation makes it more difficult for us.
"So many of our rivals will arrive with a distinct advantage, but we are certainly prepared for the challenge because we want to compete at the highest level."
Guerrieri will take the place of Ali Jackson, who moved over to the Ultimate team to take his place on his graduation to the World Series.
