Jack Harvey will return to the Verizon IndyCar Series in 2018 for a partial-season programme with Schmidt Peterson Motorsports and Michael Shank Racing.

Harvey, 24, was a two-time runner-up in the Indy Lights series before making his IndyCar debut at last year's Indianapolis 500 in a joint entry between Shank and Andretti Autosport.

Harvey returned for the final two races of the season with Schmidt Peterson Motorsports at Watkins Glen and Sonoma, and will get more outings with the team next year as part of an expanded partnership.

The British racer has been confirmed for races at St. Petersburg, Long Beach and Sonoma, as well as the Indy 500, with more set to be confirmed at a later date.

"“I’m absolutely thrilled for this to come together and for everything to be moving forward,” said Harvey.

“I had a very positive experience racing for Mike Shank in the Indianapolis 500, and it was great to build on that with SPM in the last two races of the year. Now to be racing for Mike and to also have the support of SPM for this program, it is the best of both worlds for me.

"I want to do as well as we possibly can for AutoNation and SiriusXM, and I cannot wait for St. Pete to get here."

"Everyone at SPM is really excited for this partnership with Mike Shank, his team and, of course, Jack Harvey who we’re so pleased to welcome back into the organization,” SPM team co-owner Sam Schmidt said.

“We’re really looking forward to working with AutoNation and SiriusXM again as well. We continue to look for ways to strengthen our team and improve our core operations, and we think this multi-year partnership will do just that.

"Mike’s history in motorsport speaks for itself, and we’re pleased he has decided to expand his INDYCAR program and involving us in that endeavor."
