Speeds rose considerably on the second day of practice for the 102nd Running of the Indianapolis 500 with Marco Andretti the first driver to exceed 227 mph behind the wheel of his Andretti Autosport Honda equipped with the Verizon IndyCar Series’ new universal aero kit.

Scheduled for seven hours, Practice 3 was slowed by five yellow flags for a total of 43 minutes and 21 seconds.

Andretti’s fastest tow-assisted lap came midway through his running on his 60th of 117 total laps. With an average speed of 227.053 mph, Andretti easily topped the Practice 3 speed chart and sits atop the combined timesheet after three practices. At 232.769 mph, Andretti also had one of the highest trap speeds recorded.

Scott Dixon laid down the day’s second-fastest lap in his No. 9 Chip Ganassi Racing Honda, speeding to a tow-assisted velocity of 226.329 mph. Rahal Letterman Lanigan Racing’s Takuma Sato and Schmidt Peterson Motorsports’ Robert Wickens were third and fourth fastest, resepctively, and were both over 226 mph. The quartet gave Honda a lockout of the top four positions.

Charlie Kimball’s No. 23 Carlin Chevrolet was the fastest representative of the bowtie brand, averaging 225.887 mph on its best trip around the oval. The Chevrolets of Tony Kanaan, Gabby Chaves and Ed Carpenter placed sixth through eighth on timesheet.

Oriol Servia delivered a top-10 speed for Scuderia Corsa with the Spaniard’s 224.934 mph lap good for ninth on the leaderboard. Sage Karam closed out the top 10 in his Dreyer & Reinbold Racing Chevrolet. The American manufacturer split the group evenly with its Japanese rival.

Kanaan led the way on the no-tow speed chart with a 223.048 mph lap. Carpenter, Sebastien Bourdais, Matheus Leist and Alexander Rossi completed the top five no-tow speeds.

Four of the five yellow flags during Practice 3 were for track inspections or debris. The fourth, at 4:02 p.m. EDT, was thrown for Kanaan’s No. 14 Chevrolet which lost power and stalled on the backstretch. The car was towed in without incident and both the session and Kanaan were able to resume.

A total of 3,349 laps were turned among the 35-car field. James Hinchcliffe made 129 revolutions of the 2.5-mile Indianapolis Motor Speedway — nearly 65 percent of the race distance he’ll experience on race day.

Indianapolis 500 practice continues Thursday and Friday from 11 a.m. to 6 p.m. with live streaming available on INDYCAR Race Control.
