In the context of Chevrolet vehicles, RS stands for Rally Sport. It's a trim level that is often used to denote a sporty or performance-oriented version of a particular model. In the past, RS was a specific model designation for the Camaro and was associated with a sportier appearance package. It is now that it has become a trim level for a range of Chevrolet vehicles. These vehicles include the Chevrolet Blazer, the Chevrolet Malibu, and the Chevrolet Traverse. The RS trim level usually includes sportier exterior styling, such as unique front and rear fascias. Alongside that, you also get blacked-out or body-colored accents, and larger wheels. It may also include upgrades to the suspension, brakes, and interior, such as sports seats, a sport-tuned suspension, and a more powerful engine. Overall, the RS trim level is designed to appeal to drivers who want a sportier and more dynamic driving experience.
