The 45-year-old winner of the 2008 Daytona 500 retired at the end of the 2021 campaign after 20 full seasons in Cup.
But the 2014 Cup Series runner-up will make his first appearance with the Next Gen car at Darlington Raceway next weekend in the #15 Mustang driven by 2009 Formula 1 world champion Jenson Button at Circuit of the Americas last month.
“I am grateful for the opportunity to work with Rick Ware Racing and Ford,” said Newman, who is reunited with the Blue Oval after racing Fords for Roush Fenway Racing (now RFK Racing) from 2019 to 2021.
“I think this will be good for all of us with our combined experience and knowledge.
“Being part of the Throwback Weekend at one of my favorite tracks in Darlington is pretty special. After recently being named one of NASCAR’s 75 Greatest Drivers, it carries even some significance.”
The veteran racer made 725 starts at Cup level, winning 18 races including the 2013 Brickyard 400 at Indianapolis Motor Speedway during spells with Team Penske, Stewart-Haas Racing and Richard Childress Racing.
Newman's most productive season came in his second Cup campaign in 2003, when he won eight times for Penske.
After stepping away from NASCAR he spent the summer of 2022 competing in Tony Stewart's Superstar Racing Experience, winning once at Stafford and ending the season as the championship runner-up.
It's currently unclear how many races Newman will run and when his other starts may be.
