Trenton Estep swept the Porsche Carrera Cup North America presented by The Cayman Islands round on the streets of Toronto by winning Sunday’s shortened race from pole.
The MDK Motorsports driver added to his Saturday success with a commanding drive from the front of the grid, clearing away from a hard-fought battle for the remaining podium positions between Parker Thompson, Riley Dickinson and Kay van Berlo.
Sunday’s Carrera Cup contest was due to last 40 minutes but instead ran to a significantly reduced 24-minute clock due to an extended cleanup from the preceding Sports Car Championship Canada round.
Estep controlled the delayed race start, whereas fellow front-row starter Kay van Berlo lost two places to Thompson and Dickinson on the opening lap.
The field was kept tight by an early safety car intervention after Travis Wiley, who finished fourth in Race 1, came to a halt against the tire barriers at Turn 3.
Racing resumed with 16 and a half minutes remaining and Estep once again did well to maintain his lead.
Thompson initially looked able to keep sight of the MDK driver, but after a few minutes he was instead focusing on the pressure being applied from Dickinson in third.
Dickinson tried several times to pass Thompson around the 1.75-mile lap, even making light front-to-rear contact as they negotiated the Turn 1 right-hander.
Thompson held on until the checkered flag, despite Estep leaving him behind by seven seconds, while Dickinson came through just eight-tenths behind to complete the podium.
Championship leader van Berlo took fourth, which ended a streak of four consecutive podium results for the Dutchman.
Varun Choksey was fifth, one place ahead of Pro-Am winner Efrin Castro.
Adam Adelson finished seventh, while Jeff Kingsley recovered to eighth after initially running two places higher until he ran wide at Turn 3 and had to reverse out of the barriers.
Bill Smith claimed Am category honors in 11th position overall.
RESULTS: Race 2
