Redesigned in 1965, the Impala set an all-time industry annual sales record of more than 1 million units in the U.S.. All new full-size Chevrolets eschewed the “X” frame for a full-width perimeter frame, a new body which featured curved, frameless side glass (for pillarless models), sharper angled windshield with newly reshaped vent windows, and redesigned full-coil suspension.
In 1965 Chevrolet introduced the Impala Caprice, exclusively as a four-door hardtop. Caprices received tufted upholstery, wood grained accents on the dashboard and specialty pulls on the insides of the doors. This “halo” model also featured the “spinner” wheel covers from the Impala SS, with the “SS” logo centers replaced by a Chevrolet “bowtie” emblem. The Super Sport’s blackout rear trim strip below the triple taillights was also used, with the “Impala SS” emblem deleted of course. The Caprice Custom was reintroduced as the Chevrolet Caprice in 1966, taking the top position in the full-size Chevrolet lineup.
Engine choices included the inline six-cylinder as well as the small-blockand big-block V8s. A new three-range Turbo Hydra-Matic automatic transmission was optional for 396 cu in (6.5 L) V8. The old 409-cubic-inch (6.7 L) “W” engine was discontinued early in the 1965 model year, so early-production 1965s got the 409, as well as 1/10 of 1% had the 396 CID big-block. Other later-built cars had the 396-cubic-inch (6.5 L) as the big-block option. Two-speed Powerglide, as well as 3- and 4-speed manual transmissions were available. As with previous years, Impalas featured more chrome trim inside and out, with pleated tufted upholstery and door panels. The Impala would be the #2-selling convertible in the U.S. in 1966, with 38,000 sold; it was beaten by the Mustang by almost 2:1.
The 1967 model was redesigned with enhanced Coke bottle styling which featured Corvette-inspired front and rear fender bulges. The curves were the most pronounced with the 1967–1968 models. In keeping with federal regulations, safety features were built into Impalas during the 1967 and 1968 model years, including a fully collapsible energy-absorbing steering column, side marker lights, and shoulder belts for closed models. A black 1967 Sport Sedan 4-door hardtop was used in the television seriesSupernatural, and as such, this model has seen a substantial increase in value to collectors. The impala in Supernatural is not only a car but a home and will always be remembered as such.
