Rebellion entered the history books as the last-ever overall winner in the American Le Mans Series, as Nick Heidfeld, Neel Jani and Nicolas Prost won the 2013 Petit Le Mans.
The trio cruised to victory at Road Atlanta after erstwhile race leader Pickett Racing was forced to retire with an irreparable overheating issue shortly after mid-distance.
The Pickett HPD had a one-lap advantage over its Anglo-Swiss rival before Rebellion's misfortune, due in part to Jani serving a stop-go penalty after hitting the PR1 Mathiasen LMPC entry in the first hour.
With this year's LMP1 champions out of the picture, Rebellion was faultless in claiming its second consecutive Petit victory by a comfortable seven-lap margin.
The #551 Level 5 HPD finished second overall when it claimed LMP2 honours in the hands of Ryan Briscoe, Marino Franchitti and team owner Scott Tucker.
They were embroiled in a race-long duel with the #01 Extreme Speed HPD, the outcome of which was only decided in the final hour when series returnee David Brabham experienced a delayed final pit stop and fell to second in class.
The sister Level 5 car of Guy Cosmo and experienced HPD drivers Jonny Kane and Peter Dumbreck finished third in LMP2, a position they had maintained throughout the majority of the race.
BAR1 Motorsport took LMPC victory in its #8 entry after a determined drive by Kyle Marcelli, who finally found a way past ALMS debutant Oswaldo Negri with just over two hours left on the clock.
FALKEN RECOVERS TO GT TRIUMPH
Nicky Tandy, Wolf Henzler and Bryan Sellers took the GT spoils in what was an ultra-competitive field, and the class lead changed on almost lap-by-lap basis during the first-half of the race.
The order looked to have settled down seven hours in, with the Risi Ferrari squad enjoying a 15-second lead.
That was before Olivier Beretta tried to pass a GTC competitor around the outside of Turn 6, and too much momentum sent him careering into a wall.
He lost 25 seconds and a door mirror and was forced to pit for repairs, dropping him down to fourth in class as a result.
This promoted Tandy to first in class, a fantastic turnaround after he had fought just to stay on the lead lap at one point, but swift pitstops and timely caution periods allowed the Falken Porsche to rise up the order.
The Briton held his lead until the end, overcoming a brief headlight issue after darkness descended and fending off Dirk Muller in the #56 RLL BMW when racing resumed with 10 laps remaining after a late caution period.
The #45 Flying Lizards Porsche traded GTC class pole for victory after an intense three-car battle and it looked like Damien Faulkner would claim second, but the TRG Porsche came to a halt on the exit of Turn 2 with 15 laps remaining to bring out the final full course caution.
His misfortune was the Dempsey team's gain, which showed good pace when three-time Grand-Am champion Andy Lally took control of the Porsche 911, and finished second, ahead of JDX Racing.
