Race 2 of the night began with complete carnage, with almost the entire field caught up in accidents on the opening corners following the reverse grid start.
Wildcard Joey Logano, who races with rolling starts in the US, was the main culprit, spinning off the start line from 2nd on the grid, meaning cars were going everywhere trying to avoid the 2018 NASCAR Champion’s Mustang.
Whincup, who started in 8th position slowly made his way to the front where he had a battle with Dunlop Super2 rookie Angelo Mouzouris.
Whincup held off the rookie and went on to claim his first Eseries race win.
Wildcard Alexander Rossi finished 2nd and McLaughlin recovered to finish third and maintain his Championship lead.
Cam Waters was fourth, meaning he was the ARMOR ALL Driver of the Round, taking home $1000 for his charity of choice.
Next week’s sixth round heads to Europe, where races will be staged at Circuit de Spa-Francorchamps, the home of the Belgium F1 Grand Prix and Nürburgring Grand-Prix-Strecke, the home of the German F1 Grand Prix.
