Andretti Autosport is said to be talking to Chevy about switching to it from Honda, according to sources throughout the IndyCar paddock. The terms of Andretti’s current deal with Honda could not be confirmed by presstime, but it is routine for teams to evaluate manufacturer relationships as deals come up for renewal. Andretti declined comment on the talks. Chevy said it does not comment on business relationships, while Honda said it is “not aware at this time” of plans for Andretti to switch to Chevy. Andretti is a longtime Honda team, but the team did switch to Chevy for the ’12 and ’13 season before going back to Honda in ’14. Another big swing occurred this season when Chip Ganassi Racing switched from Chevy to Honda, altering the balance of power between the two manufacturers in the Verizon IndyCar Series in a similar way that a prospective Andretti-Chevy deal would. Ganassi’s move to Honda has been the source of private griping from some Honda teams since it was announced late last year. Those teams feel that their positions in the Honda pecking order has been leapfrogged by Ganassi. Whether that is factoring into Andretti’s decision making could not be confirmed.
