1966 saw a complete restyle of the Chevelle on the previous frame that included smooth contours, a broad new grille and bumper treatment, and curved side windows. Bulging rear fender lines and a "flying buttress" roofline (tunneled into the "C" pillar) were highlights of the '66 hardtops, shared with other GM "A" body models.
The new body reflected the "Coke bottle" body shape that became the fad for American cars in the mid-1960s. A 4-door hardtop-styled Sport Sedan joined the Malibu series. It was an attractive car and was offered through 1972, but never achieved the high-production figures as the pillared sedan. Chevelles continued in 300, 300 Deluxe, and Malibu trim. Available engines were a 327-cubic-inch V8 instead of either of the sixes, or the mid-level option, a 220-horsepower 283-cubic-inch V8. Judicious attention to the options list could add a tachometer, mag-style wheel covers, and sintered-metallic brakes. Four-way power seats, a tissue dispenser, and cruise control were optional.
