Bentley increased his CART schedule in 1992 with Coyne to include additional races outside of Vancouver, and would run seven races. That year's Vancouver event saw four Canadian drivers including Bentley, who finished 14th while managing a back injury. He continued racing for Coyne in 1993. During the buildup to the Indianapolis 500, Bentley was hospitalized and suffered burns on his hands and neck in a practice crash that caused a fuel regulator to split and pour methanol fuel into the cockpit. Bentley continued driving for Coyne in 1994, when the team brought on Pro Football Hall of Fame running back Walter Payton as a co-owner, but Payton Coyne Racing struggled with performance due to outdated equipment.
