An all-new, sharply sculpted body with tapered fenders and a rounded beltline highlights a redesign for 1968, including a shorter wheelbase and rear-quarter “kick-up” that gives the Chevelle an aggressive stance. Despite only minor aesthetic upgrades in ‘69 and the SS becoming an option rather than a separate series, the Chevelle is championed as America’s most popular mid-sized car, outsells every competitor, and rules all muscle cars. 1970 is a pinnacle year, a favorite by a majority of enthusiasts, and a best-seller both then and now. SS396, SS454, and COPO editions debut, and dealers like Yenko and Baldwin push the limits with custom builds. ’71 and ’72 cars get single-headlights and a final restyle, and these popular years are widely considered to be the last Chevelle muscle cars.
