Nico Hulkenberg could become the latest Formula 1-IndyCar convert, with the German getting an IndyCar test with McLaren.
Hulkenberg will drive a Chevrolet-powered Arrow SP McLaren car at Barber Motorsport Park next week.
The 34-year-old has been in and out of different cars since leaving F1 full-time in 2019.
He was drafted in by Racing Point for three races last F1 season to fill in for the team’s ill regular drivers.
But Hulkenberg recently said he is doubtful to return to F1 as a full-timer again.
His IndyCar test will give him a solid indication of whether he could consider racing in the American series.
It is well-known McLaren are in the process of expanding their current two-car IndyCar outfit to three cars. But when that happens is not fully clear.
IndyCar is quietly building a reputation for taking in exiled F1 drivers.
This season, Romain Grosjean debuted in the championship with Dale Coyne Racing. He moves to the Andretti squad next year.
Marcus Ericsson picked up two race wins and was in the championship hunt until the final few races.
Kevin Magnussen also made a one-off appearance at Road America.
