In 2014, Ganassi switched to Chevrolet engines. In a twist, Ganassi would hire 2013 Indy 500 winner Tony Kanaan to drive the No. 10 Target car, while Briscoe and NTT Data signed on for a full season in the No. 8 car. The team once again struggled during the first half of the season, but hit its stride during the second half, with Dixon winning at Mid-Ohio and Sonoma, while Kanaan won the season finale at Auto Club. For 2015, the team would sign Indy Lights champion Sage Karam to share the No. 8 with Sebastián Saavedra. Dixon would claim his fourth title in a tiebreaker with Juan Pablo Montoya on the strength of three wins at Long Beach, Texas, and Sonoma. Kanaan would not win that year, but had two runner up finishes at Texas and Fontana. Both Karam and Saavedra would struggle in the No. 8, save for a lone podium by Karam at Iowa. For 2016, Ganassi would replace Karam and Saavedra with former Formula 1 driver Max Chilton. 2016 would be a down year for the team, with Dixon winning twice at Phoenix and Watkins Glen, while Kanaan had only two podiums while Chilton and Kimball struggled.
