Crowds of people are swarming the displays at the North American International Auto Show, which is open to the public for nine days.
Automakers are flush with profits, and the show gleams with performance cars, beefy trucks and exciting experiments, from plug-in hybrids to cars carved by a 3-D printer.
Aaron Spork brought his family Saturday to check out the new Chevrolet Colorado, a pickup truck that he's getting to replace a Ford Mustang.
There's a number of performance cars at Cobo Center. Ford showed its 600-horsepower GT while Acura showed off its NSX hybrid supercar. Cadillac, BMW, Mercedes, Lexus and Porsche have introduced new performance vehicles.
