Detroit — The motorsports world came to the Motor City for the Detroit Grand Prix last weekend for the IMSA Weathertech Sportscar Championship.

And the home teams dominated.

Cadillac swept the front row of Friday qualifying in the GTP class and then won Saturday’s race over an elite field of Porsche, BMW, Acura and Aston Martin cars. Corvette did the same in the GT class — sweeping the front row, then controlling the race over European rivals with Ford Mustang not far behind. Only Lamborghini spoiled a Detroit muscle car one-two.

Detroit automakers have invested billions to become players in international motorsports, and the Detroit GP was a proof point of the momentum they’ve built. While competitors Porsche and Honda are cutting back on their motorsports programs after disastrous corporate decisions on electrification, General Motors and Ford are well-positioned this year to make a mark across the globe — including in the premier international endurance race, the 24 Hours of Le Mans in France later this month.

“What a special day for General Motors and the Cadillac and Corvette Racing teams in Detroit,” said GM President Mark Reuss after the Saturday afternoon IMSA result. “Winning both classes of the Chevrolet Detroit Sports Car Classic on the streets of the Motor City is a tremendous achievement for our motorsports, design and engineering teams.”
