2017 Indianapolis 500

The 2017 Indianapolis 500 (branded as the 101st Running of the Indianapolis 500 presented by PennGrade Motor Oil for sponsorship reasons) was a Verizon IndyCar Series race held on Sunday May 28, 2017, at the Indianapolis Motor Speedway in Speedway, Indiana, United States. The race was the premier event and the sixth race of the 2017 Verizon IndyCar Series season.

Despite a threatening weather forecast in the days leading up to the event, the race ran its scheduled distance of 200 laps (500 miles) and was won by Japanese driver Takuma Sato of Andretti Autosport. Sato, who also finished on the podium at the 2004 U.S. Grand Prix on the road course at Indianapolis, became the first Asian driver to win the Indianapolis 500. Sato assumed the lead with six laps to go and held off Hélio Castroneves over the final fifteen miles.

Two violent crashes occurred during the month, involving Sébastien Bourdais (during time trials) and Scott Dixon (during the race), respectively. Bourdais suffered a broken pelvis and other injuries, forcing him to sit out the event, while Dixon suffered a minor ankle injury.

Alexander Rossi entered the race as the defending champion. The event also featured Fernando Alonso, the first active Formula One World Championship driver to contest the race since Teo Fabi in 1984. Alonso was voted Rookie of the Year, having led 27 laps before retiring in the closing stages of the race.

The month of May activities formally began on May 13 with the fourth running of the IndyCar Grand Prix on the combined road course. Practice for the Indianapolis 500 began on May 15, and time trials were held on May 20–21. Scott Dixon, the 2008 winner, won the pole position, his third career Indy pole. Dixon's qualifying speed of 232.164 mph (373.632 km/h) was the fastest pole speed since 1996. Carb Day—the traditional final day of practice, as well as the annual Pit Stop Challenge and Indy Lights Freedom 100, were held on May 26. Support races featuring the Road to Indy were also held during the month.

The 2017 race was the third and final year contested with the Chevrolet and Honda aero kits outfitted to the Dallara DW12 chassis. Beginning in 2018, all DW12 chassis were outfitted with a universal bodywork kit. Furthermore, a development freeze was implemented for 2017, and all aero kits had to adhere to the established specifications carried over from 2016.

Among the major offseason moves, Chip Ganassi Racing switched engine manufactures from Chevrolet to Honda. Conversely, A. J. Foyt Enterprises switched from Honda to Chevrolet. KV Racing Technology, who won the 2013 race with driver Tony Kanaan, was sold to Juncos Racing, an established team in the ladder system, scheduled to make its debut at the Indianapolis 500. After losing his seat at KV Racing, Sébastien Bourdais subsequently signed with Dale Coyne Racing. Among the other high-profile moves, Josef Newgarden departed Ed Carpenter Racing and joined Team Penske.

A series of procedural rule changes were implemented by the series for the 2017 season, however, none of the rule changes significantly affected the Indianapolis 500. The IndyCar Grand Prix, which opens the on-track activities for the month, a three-day event, had only two days for the Verizon IndyCar Series. That mirrors similar changes made to other races event weekends on the schedule.
