Colton Herta returned his Harding Steinbrenner Racing Honda to the top of the timesheet when the NTT IndyCar Series opened its fifth race day of 2019 with a half-hour warm-up outing on the Indianapolis Motor Speedway road course.
- Results: 2019 INDYCAR Grand Prix Warm-Up
Carlin’s Max Chilton owned the fastest lap during a portion of the session but the running order was significantly changed before the checkered flag appeared.
Herta executed a lap more than eight-tenths of a second quicker than Chilton’s best effort to put his No. 88 machine in the top spot — where it also landed in Practice 2 and Round 2 of qualifying.
While that lap from Herta stood strong, five other drivers went faster than Chilton, relegating the No. 59 Chevrolet to the seventh spot.
Second-place qualifier Scott Dixon came within 0.3802 seconds of Herta’s time to land second on the warm-up results over fellow Honda drivers Takuma Sato, Graham Rahal, Sebastien Bourdais and Marco Andretti in the top six.
Josef Newgarden, Felix Rosenqvist and Zach Veach followed Chilton on the timesheet to complete the top 10, which included only two Chevrolets and was split by 0.9464 seconds.
Championship contender Alexander Rossi started race day 11th while sixth-place starter Will Power was 13th.
After qualifying last, AJ Foyt Racing veteran Tony Kanaan was also slowest in warm-up but isn’t scored last on the results sheet as Chilton’s Carlin stablemate Patricio O’Ward turned no laps during the session due to an alternator issue with his No. 31 Chevrolet.
The 85-lap race is all that remains of the INDYCAR Grand Prix weekend. The green flag is scheduled to fly at 3:50 p.m. EDT after NBC’s telecast opens at 3 p.m.
