1961 Chevrolet Full-Size Cars Fact Sheet

Chevrolet’s Big Change
for 1961

 

Smaller, sleeker, and crisp new styling set the stage for the 60s. And the availability of a 409 CID of W-Series V-8 didn’t hurt either.

 

General Year Information

The 1961 Chevrolets followed the General Motor’s pattern in adopting a brand new, downsized body, but varied from the corporate trend in that strictly carryover engineering was used. Grille and front areas were rather flat and square, while the rear end sported a flat V-type fin. At the front, a full-width air slot stretched above the grille, below the beveled front lip of the hood. The bevel line swept around the front body corners and ran, in a straight line, down and back towards the rear quarter panel. There, it angled upwards again, to connect with the flat V-type fin.

The Biscayne line line consisted of  the “Deluxe” (1100 Series) and Station Wagon (1135 & 1145) and the economy “Fleetmaster” (1300 Series).

All Biscanes had twin circular tail­ lamps, small hub caps and model nameplates on upper rear fender tips, while lacking side body moldings along the bevel line. Rocker panel strips were used on 1100/1200 level cars, but not on the Series 1300/1400 Fleetmaster economy models. Standard equipment consisted of dual sun visors, electric windshield wipers, cigarette lighter, front arm rests and five 7.50 x 14 black tubeless tires.

The Bel Air line was distinguished from Biscaynes by a chrome trim bar, extending from the front parking lights rearward to the trunk. Bel Air nameplates appeared at the upper rear fender; twin tail lamps were seen; small hub caps were standard equipment and no rocker sill strips were used.

As in other lines, regular sedans, Sport Sedans, Sport Coupes and station wagons all had individual rooflines with the flat-top look on regular sedans, a formal look on Sport Sedans, a rounded semi-fastback on Sport Coupes and boxy, conventional station wagon styling. Station wagons had Bel Air trim, but “Parkwood” rear fender scripts. Standard equipment matched that of Biscayne, plus foam seat cushions and Deluxe steering wheel.

The Impala line were easily identified by their triple taillight treatment. They also had crossed racing flags insignia at the center of the rear deck and at the rear fenders, with model identification scripts in the latter location as well. Deluxe wheel discs and wide side moldings, with contrasting insert panels, were other visual distinctions of this top Chevrolet line. Nomad station wagons had Impala level trim, but “Nomad” logos on the rear fenders.

Standard equipment lists began with Bel Air features and added parking brake, glove box and backup lights; anodized aluminum trim; electric clock and 8.00 x 14 size tires on convertibles. All 1961 Chevrolet station wagons had 8.00 x 14 tires and nine-passenger wagons had power tailgates.

NOTE: A total of 142 Impalas were manufactured with Super Sport equipment and the 409 cubic inch V-8.
