Logano seemed to think Keselowski spun his tires and that created the bottleneck, but Keselowski believed he had help from behind.
"I haven't seen the replay, I just know my rear tires were off the ground before I got to the restart zone," he said. "Eventually I got hit so hard it pushed my foot in the gas pedal, made myself look like a (fool). That was the deal. Never had another chance."
Nobody came close to Kahne, who drove his Hendrick Motorsports Chevrolet to the win by 1.7-seconds. Hendrick drivers have now won two of the first four races this season.
Kyle Busch snagged second from Keselowski, who took over the Sprint Cup Series points lead as the only driver to open the season with four top-five finishes. Kurt Busch finished fourth and was followed by Bowyer and Dale Earnhardt Jr.
Ryan Newman was seventh, Brian Vickers was eighth and Paul Menard and Jamie McMurray rounded out the top 10.
The race changed dramatically with 110 laps to go in a bizarre crash between leaders Gordon and Matt Kenseth. Gordon was out front when he suddenly lost a tire and his car darted up the track into the wall. Kenseth had nowhere to go to avoid him and drove directly into the back of Gordon, causing heavy damage to both cars.
"You all right?" crew chief Alan Gustafson radioed Gordon.
"Yeah, I'm OK. Did we take out Matt, too?" Gordon asked.
With the top two cars in the garage, the rest of the field headed to pit road to reset for the final 100 laps.
"I hate that for Matt Kenseth," Gordon said. "He was coming, and it was just a matter of time before he caught us. We needed points. This definitely isn't going to get us many."
Kenseth, winner of last week's race at Las Vegas, said the crash was unavoidable.
"There's not a lot either one of us can do about that," he said. "There was nowhere to go."
Before the Gordon-Kenseth crash, Gordon and Logano were dueling for the lead. Gordon used a two-tire stop with about 175 laps to go to gain eight spots on pit road and take the lead. Logano chased Gordon around the 0.533-mile bullring, pulling even with the four-time champion as he exited the corners only to lose ground on the straights.
