The Chevrolet Caprice is a full-sized automobile produced by Chevrolet in North America for the 1965 to 1996 model years. Full-size Chevrolet sales peaked in 1965 with over a million sold. It was the most popular American car in the sixties and early seventies, which, during its lifetime, included the Biscayne, Bel Air, and Impala.
Introduced in mid-1965 as a luxury trim package for the Impala four-door hardtop, Chevrolet offered a full line of Caprice models for the 1966 and subsequent model years, including a "formal hardtop" coupe and an Estate station wagon. The 1971 to 1976 models are the largest Chevrolets ever built. The downsized 1977 and restyled 1991 models were awarded Motor Trend Car of the Year. Production ended in 1996.
From 2011 to 2017, the Caprice nameplate returned to North America as a full-size, rear wheel drive police vehicle, a captive import from Australia built by General Motors's subsidiary Holden—the police vehicle is a rebadged version of the Holden WM/WN Caprice. The nameplate also had a civilian and police presence in the Middle East from 1999 to 2017, where the imported Holden Statesman/Caprice built by Holden was marketed as the Chevrolet Caprice in markets such as the UAE and Saudi Arabia.
A police package, orderable under GM's Regular Production Option code 9C1, was introduced for the new base-model Caprice that replaced the Impala for 1986. In the 1986 Michigan State Police tests, the Chevrolet Caprice was competitive with the Ford LTD Crown Victoria, Dodge Diplomat and Plymouth Gran Fury. The Caprice had the fastest quarter-mile times of the three, and the best fuel economy. The Dodge and Plymouth outran the Caprice in the 0–100 mph times, but placed last in the road course times. However, there was only a 1/3 second difference between the fastest and slowest vehicles on the road course. All four cars were very close in competition for 1986, and there was little performance difference.
For 1989, the 9C1 Caprice received some major changes to the drivetrain. All engines were now equipped with throttle-body fuel-injection (shared with the truck/van lineup and based on the LB4 4.3L TBI injection system first used with the 1985 model year passenger cars), and the 305 cu in (5.00 l) engine (RPO LO3) was now added to the option list. The available engines were now the 4.3 l (260 cu in) V6, the 305 cu in (5.00 l) and 350 cu in (5.7 l) V8s (which was only available on police package models). The V6 and 350 engines were equipped with TH700-R4 transmissions while the 305 engine used the TH200-4R transmission. The V6 and the 305 used a 3.08:1 axle ratio, while the 350-powered cars now used a 3.42:1 axle ratio. The 4.3 L remained at 140 hp (104 kW), while the 305 TBI engine was rated at 170 hp (127 kW), and the 350 TBI engine was rated at 190 hp (142 kW). Unlike the LO5 used with the GMT400 light duty truck and van line including the R/V series, the police spec LO5 used the roller camshaft sourced from its TPI equipped F bodies and Corvette along with high flow fuel injectors. The 350 powered Caprice did well again at Michigan State Police tests for pursuit rated cars. It had the fastest 0–100 mph, the fastest road course time, the highest top speed and the best fuel economy. The Dodge Diplomat and Ford LTD Crown Victoria outbraked the Caprice, and the Plymouth Fury and Dodge Diplomat had better ergonomics than the Caprice.
The California Highway Patrol (CHP) is a state law enforcement agency of the U.S. state of California. The CHP has patrol jurisdiction over all California highways and are also known as the state police. They also have jurisdiction over city roads, and have the right to conduct law enforcement procedures there.
The California State Legislature originally established the California Highway Patrol as a branch of the Division of Motor Vehicles in the Department of Public Works, with legislation signed by Governor C. C. Young on August 14, 1929. It was subsequently established as a separate department with legislation signed by Governor Earl Warren in 1947. The CHP gradually assumed increased responsibility beyond the enforcement of the State Vehicle Act and eventually merged with the smaller California State Police in 1995. It is currently organized as part of the California State Transportation Agency (CALSTA).
In addition to its highway patrol duties, the CHP also provides other services including protecting state buildings and facilities (most notably the California State Capitol) and guarding state officials. The CHP also works with municipal and federal law enforcement agencies, providing assistance in investigations, patrol and other aspects of law enforcement.
The California Highway Patrol is the largest state police agency in the United States, with more than 10,700 employees, 7,500 of whom are sworn officers, according to FBI data.
