Ed Carpenter and JR Hildebrand returned to the race along with Kanaan, but too late and too far behind to threaten for a win. The auto was shredded, but the tub of the vehicle remained intact and Dixon was not seriously hurt.
Despite not having any cars qualify in the top 8 for the race, Chevrolet won the race with Will Power and took both 3rd and 5th place with Simon Pagenaud and Gabby Chaves, respectively.
Instead, Dixon got taken out in one last crash to end a wild race at the repaved and reconfigured 1 1/2-mile track and Power won under caution.
The 36-year-old Australian Team Penske driver claimed his second win of the season after a 248-lap race that was repeatedly interrupted after crashes involving multiple cars.
Power, who led 180 of the 248 laps, was the leader when Dixon got wrecked by Takuma Sato, and finished ahead of Tony Kanaan, who other drivers and at least one owner blamed for a big crash earlier that led to a almost 31-minute red flag. He had a run to the inside of Dixon with five to go but ran out of asphalt.
FORT WORTH, Texas (AP) Will Power was trying to figure out how to hold off Scott Dixon for the lead as the two went side-by-side in the closing laps of the IndyCar race at Texas. I'm definitely going to go see him if he wants to see me, or I'll call him.
With only a handful of laps remaining Sato dipped a wheel on the grass at Turn 1 while fighting for P2 with four-time champion Dixon.
The first caution came out when 2016 Indianapolis 500 victor Alexander Rossi found himself three-wide between Kanaan and Dixon entering Turn 3.
"I got back in it pretty quick and the team made it easy because the vehicle was so good from the start, to be honest", said Vautier, filling in for the injured Sebastien Bourdais this weekend. Hinchcliffe spun near the exit of pit road, forcing contact with Helio Castroneves and Sato. Kanaan, who was in contention for the victory, lost two laps by serving that penalty. Kimball will start in the pole position with Scott Dixon in the second spot for Saturday's scheduled race. Castroneves went hard into the wall and eventually came to rest on the inside of the third turn. It was the Team Penske driver's second victory this season and 31 of his career.
Kanaan appeared to move up and touch James Hinchcliffe's vehicle, which careered into Mikhail Aleshin. Hinchcliffe's auto bounced off Mikhail Aleshin's vehicle and that started a chain reaction that collected Tristan Vautier, rookie Ed Jones, Ed Carpenter, JR Hildebrand, Carlos Munoz and Ryan Hunter-Reay.
The carnage to that point left 11 of the 22 starters still on the track.
Dale Coyne, team owner for Vautier and Jones, confronted Kanaan while he was sitting in his vehicle during the red flag stop.
Despite the stop-and-hold penalty that put Kanaan a couple laps down, it clearly didn't torpedo his chances as he was able to battle back and secure second place. The yellow came out on Lap 190.
Robby Gordon's high-flying Speed Energy Stadium Super Trucks ran races before and after the Indy vehicle race.
Twenty-two cars started Saturday night's race. The layout included several jumps, including a 140-foot flight between dirt ramps, part of the legends auto oval, most of pit lane and a jump into the infield.
