History:

The Chevrolet Caprice is a large-sized model from Chevrolet.

Very well known in the movies as a taxi, police vehicles or FBI vehicle. He started his career as a luxury car, but over the years he left his trademark with the police, due to his good performance. In the units between 1991 and 1996, this power was generated by the LT1 engine, a 5.7L V8 derived from the Corvette, but with 260 horses, instead of 300 horses. The Chevrolet Caprice was in the police force for many years and even today in some places in the interior of the USA it is used as a police vehicle. It was also the most widely used taxi car in New York in the 1990s, before the Ford Crown Victoria took over as a taxi.

In 2011 he returned to the USA as a police vehicle, with a platform and assembly by his Australian relative Holden.

1980–1985:

The 1980 Caprice Classic saw its first major revision since the 1977 downsizing. To further improve the fuel economy of the car, efforts were made to reduce weight and improve aerodynamics. The Caprice received new exterior sheet metal, without drastically changing the look of the car. To improve aerodynamics the hood was tapered lower, while the trunk area was higher. 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 (45 kg) 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 gallons (95 l; 21 imp gal) 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 cu in (4.1 L) 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 stroke as the 305 cu in V8. California emission cars used the Buick 3.8 L (231 cu in) V6 engine. The Chevrolet 3.8 L 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 lb⋅ft (34 N⋅m) more torque than the 3.8 L (200 lb·ft vs 175 lb·ft). The 3.8 L V6 did boost Chevrolet Caprice’s fuel economy to an EPA estimated 20 miles per US gallon (12 L/100 km; 24 mpg‑imp) city and 29 miles per US gallon (8.1 L/100 km; 35 mpg‑imp) highway, the highest a full-size Chevrolet had been rated to date.

The base V8 engine was new for 1980. The 4.4 L 267 cu in V8 rated at 115 hp (86 kW) and was the standard engine for station wagons. This engine had a Rochester Dualjet carburetor, and was not available in California. The two-barrel carburetor on the 305 cu in (5.0 L) V8 was replaced with a four-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 (5.7 L) V8 was no longer available, except as part of the police package option. The Oldsmobile-built 350 cu in Diesel V8 was added to the option list for 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.
1981 models saw only minor revisions. Styling was unchanged other than the grille which remained egg crate style but now had larger sections. Refinements included redesigned front disc brakes for less drag and a translucent plastic master cylinder reservoir. The cruise control became equipped with a resume feature, while wire wheel covers had locking bolts to secure them in place. This was the last year for the Delco GM 40-channel CB radio built into the AM/FM radio option.
The engine line-up remained unchanged, although the 3.8 L 229 cu in V6 was now rated at 110 hp (82 kW) and the 5.0 L 305 cu in V8 was rated at 150 hp (112 kW). All engines were updated with the Computer Command Control (CCC) system which included an electronically metered carburetor. This change occurred in 1980 for California emission cars and did not occur to Canadian emission cars until 1987. The Oldsmobile-built 350 cu in Diesel V8 was added to the option list for the coupe and sedan models during the model year.
1982 models saw only minor styling revisions. The model line-up was reduced by one, with the Caprice Landau coupe dropped. Remaining were the sedan, sport coupe, six-passenger wagon, and the eight-passenger wagon. A new four-speed automatic overdrive transmission with a lock-up torque converter joined the powertrain line-up. This transmission helped boost highway fuel economy, while improving city performance with a 3.08:1 rear axle ratio. The overdrive transmission was only available with the 305 cu in V8, and was a mandatory option for this engine.
