Scott Dixon won the IndyCar championship, using a fifth-place finish at Auto Club Speedway in Fontana to deny Helio Castroneves his first title.
Will Power won Saturday's season finale -- a year after he crashed in this race to blow his own title chances -- and salvaged the night for Penske Racing.
But the big prize went to Dixon, who won his third series title and gave Target Chip Ganassi its 10th championship since 1990.
Sam Hornish Jr. had given Roger Penske his last IndyCar title in 2006. But the team owner made a major error, calling Castroneves to pit lane before the pits were open.
Castroneves had to serve a drive-thru penalty that dropped him a lap down. He finished sixth at the two-mile oval.
NASCAR Sprint Cup: Aric Almirola claimed the pole when rain washed out qualifying for Sunday's race at Talladega Superspeedway, forcing the field to be set based on practice speeds.
Almirola and Richard Petty Motorsports teammate Marcos Ambrose went out for Friday's first practice thinking there was a decent chance of rain Saturday. So they hooked up in the draft with the idea of putting up a fast time. The strategy worked at the 2.66-mile trioval -- Almirola posted a 202.000-mph lap, Ambrose was third at 201.876. Jeff Burton (201.987) will start from the outside of the front row.
Chase leader Matt Kenseth will start from the 12th spot.
NASCAR Truck Series: Winner Johnny Sauter survived a crash on the final turn at Talladega that took out Kyle Busch and everyone else racing at the front of the pack.
Sauter was the only one to be spared from a 12-truck crash that occurred when Jeb Burton got tangled up with Busch, sending the Sprint Cup star slamming into both inside and outside walls.
Most of the drivers were treated at the infield medical center and released, but Justin Lofton was transported to a hospital for further evaluation. NASCAR did not reveal the extent of his injuries.
"I looked in my rearview mirror and saw smoke and trucks were spinning everywhere," Sauter said.
American Le Mans Series: Neel Jani, Nicolas Prost and Nick Heidfeld captured the Petit Le Mans at Road Atlanta, overcoming early problems in the final American Le Mans Series event.
The No. 12 Lola-Toyota posted a six-lap win in the 1,000-mile race at the 2.5-mile circuit. The series is merging with Grand-Am to form the United SportsCar Championship.
