1980 Chevy Caprice
Caprice Classic saw its first major revision since the 1977 General Motors downsizing. To further improve
the fuel economy of the car, efforts were made to reduce weight and improve
The Caprice received all new exterior sheet metal, without
drastically changing the look of the car. To improve aerodynamics the hood was tapered lower, while the trunk area
The grille was now an egg crate style while the tail-light
panel featured three separate square lights per side. All the doors and components within were redesigned to be
lighter, including the window crank mechanisms, which now used a tape drive mechanism.
Greater use of aluminum including in bumper reinforcement and
in sedan/coupe radiators helped to further reduce the overall weight of the vehicle. 1980 models were approximately
100 pounds lighter than 1979 models.
The new styling increased the trunk capacity of both coupes
and sedans to 20.9 cubic feet (0.59 m3). This increase was also partially achieved
with a now standard compact spare tire on a 16-inch (410 mm) wheel.
A new frame lift jack replaced the bumper mounted model. A
larger 25 US gallon fuel tank was standard equipment in sedans and coupes. Easy-roll radial tires, improved
anti-corrosion measures, low friction ball joints and larger front suspension bushings were also new for 1980.
Puncture-sealant tires and cornering lights were new options.
The 250 six, was replaced by a new 90 degree
Chevrolet 3.8 L
(229 cu in) V6 as the base engine
for sedans and coupes. This engine shared the same bore and stoke as the 305 cu in V8. California
emission cars used the Buick 3.8 L (231 cu in) V6 engine.
The Chevrolet 3.8L was rated at 115 hp (86 kW) while
the Buick V6 engine had a 110 hp (82 kW) rating. Although the 3.8 L V6 had the same horsepower
rating as the 250 six used in 1979, the 250 had 25 ft·lbf (34 N·m) more torque than the 3.8 L
(200 ft·lbf vs 175 ft·lbf). The 3.8 L V6 did boost Chevrolet Caprice's fuel economy to and EPA
estimated 20 MPG city and 29 MPG highway, the highest a full-size Chevrolet had been rated to
The base V8 engine was new for 1980. The
4.4L 267 cu in V8 rated at 115 hp (86 kW) and was the standard engine for
station wagons. This engine had a 2-barrel carburetor Rochester Dualjet carburetor, and was not available in
The 2-barrel carburetor on the 1980 305 cu in V8 was
replaced with a 4-barrel increasing the 305's output to 155 hp (116 kW). This was now the most powerful
engine option (standard on California station wagons), as the 350 cu in V8 was no longer available,
except as part of the police package option.
The Oldsmobile-built 350 cubic-inch Diesel V8 was added to the option list for the 1980 station wagons. This engine was rated at
105 hp (78 kW) and 205 lb·ft (278 N·m). To further increase fuel economy, all transmissions
were equipped with an electronically controlled lock-up torque converter clutch for 1980.
