Juan Pablo Montoya and Arrows McLaren SP will team up for a second year running next May for the 106th running of the Indianapolis 500.
Montoya, who competed for McLaren in Formula 1 in 2005 and 2006, winning three Grands Prix with the Woking-based outfit, joined forces with the latter's IndyCar outfit in 2021.
The effort yielded a ninth-place finish for the Colombian, who is also a two-time victor at the Brickyard.
This year, Montoya will steer AMSP's Mission Food-supported #6 third entry alongside the cars of the team's regular drivers, Pato O'Ward and Felix Rosenqvist.
"I'm excited to return to Indianapolis with Arrow McLaren SP and Mission, to once again compete in a race that holds a special place in my heart – the Indianapolis 500," Montoya said.
"I had a great experience with the team last year and look forward to building on the progress we made in 2021.
"I think we have a real shot at competing at the front of the field and challenging for the win."
McLaren Racing CEO Zak Brown welcomed Montoya back to the team for the one-off in the blue ribband event.
"We’re delighted to have both Juan Pablo and Mission Foods back for another Indianapolis 500," said Brown.
"Juan Pablo is an institution in motorsport, with two Indianapolis 500 victories and an impressive Formula 1 career with multiple wins for McLaren.
"He adds experience that really benefits our team, giving us another driver with the potential to win anytime he steps into the car."
