1969 Chevelles were billed as "America's most popular mid-size car." They showed only minor changes for 1969, led by revised front-end styling. A single chrome bar connected quad headlights, and a slotted bumper held the parking lights. Taillight lenses were larger and more vertical, flowing into the quarter panels. Front vent windows began to fade away now that Astro Ventilation was sending outside air into several Chevelle models.
The Super Sport included a 325-horsepower 396-cubic-inch V-8 beneath a double-domed hood, along with a black-out grille displaying an SS emblem and a black rear panel. More potent editions of the 396 engine also made the options list, developing 350 or 375 horsepower (280 kW).
