Tony Kanaan has gone quickest in the final practice session on Carb Day in Indianapolis.
Kanaan lapped the speedway at a best time of 39.5099s (227.791mph, 366.594km/h) in the #14 AJ Foyt Racing Chevrolet, a comfortable margin ahead of next-fastest Scott Dixon.
Dixon’s quickest in the #9 Chip Ganassi Honda was 39.8787s (225.684mph, 363.203km/h), with Marco Andretti (#98 Andretti-Herta w/ Curb-Agajanian Honda), Sebastien Bourdais (#18 DCR w/ Vasser-Sullivan), and Charlie Kimball (#23 Carlin Chevrolet) rounding out the top five.
Last year’s winner Takuma Sato (#30 Rahal Letterman Lanigan Honda) was sixth, Will Power (#12 Team Penske Chevrolet) seventh, James Davison (#33 Foyt w/ Byrd-Hollinger-Belardi Chevrolet) 13th, and pole-sitter Ed Carpenter (#20 Ed Carpenter Racing Chevrolet) 14th.
The hour-long session, run in relatively warm conditions which are expected to be repeated in Sunday’s race, ran largely without incident.
Danica Patrick’s #13 Ed Carpenter Racing Chevrolet did suffer an electrical issue which restricted her running, although she still managed to be eighth at day’s end.
