Sami-Matti Trogen came from last to first to win the Subaru iRX All-Star invitational finale at Hell as Mitchell DeJong rounded out a championship-winning Esports campaign with a ninth-place finish.
DeJong had already clinched the championship after taking his fourth win in the six-race series last time out, winning at Atlanta Motor Speedway despite sustaining severe suspension damage in the final.
He began the main event on the third row of grid and was one of six drivers to take the joker on the first lap of 10. However, his hopes of ending his season with five wins from six ended when he and Sage Karam made contact on the opening lap, dropping both way back from the main pack.
The incident opened the door for reigning iRX world champion Trogen to steal his second win of the tournament, having previously won the fourth round at Lucas Oil Raceway.
Trogen, who started the final at the back of the reversed grid by virtue of his strong performance in the heats, carved his way through the 10-car field and was on the point by lap five after passing Travis PeCoy, both having opted to leave their joker until the final lap.
Craig Breen got by PeCoy on that final lap to claim second, just under four tenths of a second ahead of the American, with Scott Speed taking fourth after joining the hotly-contested podium battle with four laps to go.
DirtFish-liveried driver Cabot Bigham completed the top-five, ahead of Karam who fought back from that opening lap shunt with DeJong.
Nitro RX winner Kevin Hansen was seventh, with motocross star Chad Reed eighth. The pair had battled for first place on the opening lap, but both fell towards the back after Reed ran wide and rejoined into the path of Hansen.
Newly crowned champion DeJong retired with terminal damage to his Volkswagen Beetle but was still classified ninth, two laps down.
Christian Brooks, who spent much of the race battling for a podium position with Breen, had his podium hopes dashed after he was handed a 10-second penalty for avoidable contact early on in the race. After hitting a wall on lap eight, he was eventually classified last.
