Chevrolet Impala 1961-1964 Third generation

The third-generation Impala arrived in 1961 looking like nothing Chevrolet had built before, and it produced two body styles that collectors now hunt specifically because almost nobody wanted them when they were new. It also produced a 409 that got its own hit song, a dashboard where the temperature gauge was replaced by a warning light, and a 1964 engine option good for 425 horsepower. Read on for what separates the good years from the great ones.

There is a specific kind of car that was ignored when it was new and is fought over now, and the third-generation Impala produced two of them in a single model year. One was a body style so unpopular that Chevrolet only offered it once. The other was a forty-three dollar option that buyers argued about at the dealership and frequently declined. Both are now the details that separate a good car from a great one at auction, and neither had anything to do with horsepower. The engines are a different story entirely, and by the end of this generation there was one making 425 of them.

The Year the Impala Stopped Looking Like a Jukebox

The 1961 model year moved the Impala onto the General Motors B platform with a completely new body, and the change in character was dramatic. Where the 1958 through 1960 cars had been ornamented and heavy-looking, the 1961 was leaner and sleeker, with squared-up, symmetrical lines that made the previous cars look dated almost immediately. It is a shape that has aged extremely well, and the whole of the third generation retains as much popularity now as it had when the cars first rolled into showrooms, which is not something you can say about most early-sixties full-size American sedans.

The One-Year Body Style Collectors Now Chase

The 1961 order sheet included a two-door pillared sedan, and almost nobody took it. It was offered that year only, and its unpopularity at the time is exactly why it has become a treasure sought after by collectors. The same year is the last for the Nomad wagon nameplate. The two-door coupes that year carried the bubble-back roofline that is now the most recognizable feature of the 1961 car, and it is worth noting how quickly that roof disappeared, because it makes a genuine bubble-top a specific thing to look for rather than a general style.

Forty-Three Dollars for Brakes People Argued About

The forty-three dollar item was power brakes. They were optional, they were controversial when they first appeared, and they were not always ordered. That resistance seems bizarre now, but power assist was still new enough that a meaningful number of buyers distrusted the feel and declined to pay for it. The practical result today is that an original power-brake car from this era is less common than you would assume, and the manual-brake cars are considerably more work to drive than their looks suggest.

1962: A Wider C-Pillar and a Beach Boys B-Side

For 1962 the roofline changed again. A broad C-pillar design was adopted for everything except the four-door hardtops, replacing the roof overhang used previously, with the rear windows now wrapping further around each side. The Sport Coupe was the popular model that year and remains a sought-after collector car, offered with what Chevrolet marketed as a convertible-roof hardtop look. Under the hood the 348 was gone, replaced by the 409 cubic inch, 6.7-liter V8, rated at 380 horsepower, or 283 kW, with a dual-quad version that neatly matched its own displacement at 409 horsepower. The 283 remained available, as did a bored-out 327 cubic inch, 5.4-liter version making either 250 or 300 horsepower depending on carburetion. The Beach Boys released 409 that same year as the B-side to Surfin’ Safari, and while it never climbed far up the Hot 100 on its own, it did more for the engine’s reputation than any brochure Chevrolet ever printed. Very few engines get a song at all, and fewer still get one that outlived the car.

How to Read a Super Sport From Thirty Feet Away

The Super Sport treatment is easy to identify once you know what to look for. The interiors were up-scaled and more finely appointed than before, with an AM/FM radio newly available on the options sheet, and there was additional chrome trim across the whole Impala range. But the SS specifically carried the triple taillight configuration housed in a full-width aluminum and chrome panel, with matching treatment on the side moldings, and that full-width rear panel is the single most reliable visual identifier of a real Super Sport at a distance. With the Nomad nameplate retired after 1961, the up-market wagon from this point on was simply an Impala.

The Transmission Chevrolet Would Rather Forget

The transmission situation is the part of this story Chevrolet does not put in anniversary retrospectives. General Motors was having genuine problems with the Turboglide, which was dropped after 1961 and left the two-speed Powerglide as the only automatic on offer for the rest of this window. Neither unit had a reputation that survived the decade intact, and the practical consequence for anyone buying one of these cars today is that a great many have been converted to later automatics or to a manual. That is not necessarily a bad thing to drive, but it matters enormously for originality and it is one of the first things a knowledgeable buyer checks.

1963: Sharper Lines and a Warning Light Where the Gauge Was

The 1963 restyle made the car longer and lower, with pointed fenders front and rear emphasizing the length. Taillights on the SS carried over with the same full-width chromed panel. The whole Impala range got sharper lines, and the sport sedan received a new crease in the roofline that made it a very popular model that year. A six-cylinder was still available to anyone who wanted it, but the 283 V8 was the volume base engine with the bored 327 as the most common upgrade, and the 409 remained on the order sheet in multiple states of tune. The dashboard gained a covered instrument cluster, though the temperature gauge was replaced by a warning light. A factory tachometer was available, mounting directly above the steering column, and it is one of the more desirable original options to find intact.

1964: Dual Quads, 425 Horsepower, and a Softer Shape

The 1964 car softened and rounded compared to 1963. The triple taillight assembly sat against a painted rear fascia with an inverted aluminum U-shaped trim strip across the upper portion, the rooflines carried over unchanged, and back-up lights became standard equipment across the Impala range. The news that mattered to performance buyers was the 409, which was available that year with two four-barrel carburetors delivering 425 horsepower. That dual-quad 409 is the high-water mark of the third generation and the engine that anchors the entire generation’s value in today’s market.

Four Model Years, Four Completely Different Cars

What makes these four model years so interesting as a group is how much genuine variation Chevrolet packed into a single body generation. Four distinct front and rear treatments, three different roofline strategies, a nameplate retirement, a transmission crisis, and an engine family that went from 348 to 409 to dual-quad 425 horsepower in the space of three years. A 1961 bubble-top and a 1964 SS 409 are recognizably related and almost nothing else about them is the same, which is why serious Impala people tend to specialize in one year rather than the whole run.
