With the SEMA show coming, Chevrolet lifted the veil on various performance-oriented concepts and the small car segment has not been forgotten.

Chevrolet previewed several performance-oriented concepts, including the Sonic and Cruze. These concepts will debut during the first week of November in Las Vegas at the SEMA Show, considered the world’s largest convention of automotive aftermarket parts and accessories.

“Chevrolet’s 2015 passenger car lineup is one of the strongest and most competitive in the industry, offering customers a wide range of great-looking, great-driving and well-connected choices,” said Paul Edwards, vice president, Chevrolet Marketing. “They’re personal cars, too, and these concepts suggest possibilities of how to amplify Chevrolet’s heritage of performance and fun-to-drive spirit to make them even more personal.”

Chevrolet explained he SEMA concepts feature accessories designed to allow personalization while maintaining excellent refinement and ride characteristics. General Motors’ engineers developed most of the accessories shown on the concept vehicles. Some accessories are currently available from Chevrolet dealers, while others are being evaluated for production.
