"It came to the end of its natural product cycle," said James Cain, a GM spokesman in a phone conversation with Edmunds on Wednesday.
The Captiva Sport is basically a rebadged Saturn Vue.
"(Captiva Sport) was a 99.99 percent fleet vehicle, mostly to rental companies," Cain added. "But one of the things it did was to allow us to concentrate on (Chevrolet) Equinox sales for the retail market, keeping residual values higher for that vehicle."
Cain said the new Chevrolet Trax crossover, which will debut next year, will pick up the slack left by the Captiva Sport.
"Our crossover strategy now centers on the new Trax, Equinox and Traverse," Cain said.
Production of the U.S. Captiva Sport ended in August. Chevrolet dealers are in the process of phasing out inventory.
Edmunds says: Used-car buyers should keep in mind that Captiva Sport SUVs may be in short supply due to Chevy's new strategy.
