CONCORD, N.C. -- ExxonMobil will remain at Stewart-Haas Racing after its primary driver, Tony Stewart, retires from Sprint Cup racing in November.

Mobil 1 announced Friday an extension of its deal with SHR, where it has sponsored 11 races a season for Stewart and a few others for Kevin Harvick and Danica Patrick.

The number of primary-race sponsorships for the SHR stable likely will remain similar to what the company has done in the past, with Harvick as the "lead" driver but all four SHR drivers -- Harvick, Patrick, Kurt Busch and Clint Bowyer -- having Mobil 1 primary paint schemes during the season.

The multiyear deal also includes associate sponsorship of SHR Xfinity Series driver Cole Custer.

Stewart will remain a Mobil 1 spokesman as a co-owner of SHR, which collaborates with the company to develop new products.

"They've been an incredible partner," Stewart said in a statement. "The success we've achieved has been greatly helped by Mobil 1 lubricant technology and our engineers working hand-in-hand with their engineers."

Mobil 1 joined SHR in 2011 but considered going to other teams after Stewart retired this year. The two championships -- Stewart in 2011 and Harvick in 2014 -- as well as the product development collaboration helped convince the company to remain with SHR.

"We're ready to add more wins and titles to the collection," said ExxonMobil global motorsports manager Kai Decker. "Our engineers are continuously working to advance our lubricant technology, and SHR plays a large role in how we test our engine lubricants -- ensuring consumers and race fans are getting the best product available."

Harvick said he is excited and honored to continue his relationship with Mobil 1, which had been on his car for two races this year. He has primary sponsorship by Jimmy John's for more than 20 events while Anheuser-Busch, which hasn't announced whether it will return, has had 11 races this year.

SHR has the cars for Busch and Patrick funded for 2017 but has yet to announce additional sponsorship for Bowyer.
