MCG 1:18 1978 Chevrolet Caprice: Chicago Police Department

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.

Launched in late September of 1976, the 1977 Caprice Classic was drastically downsized, which reduced its weight and exterior dimensions, while increasing headroom, rear-seat legroom and trunk space compared to 1976 models. GM called its downsizing program Project 77 and invested $600 million to develop the most changed full-size Chevrolet to date. The weight reductions from the 1976 models were 611 lb (277 kg) for coupes, 637 lb (289 kg) for sedans and 871 lb (395 kg) for wagons. 

1978 models had minor front and rear styling revisions. The engine line-up remained unchanged, but numerically lower axle ratios were used in an attempt to boost fuel economy. The 305 and 350 engines went from a standard 2.56:1 axle for 1977 (2.73:1 for wagons), to a 2.41:1 axle for 1978 (2.56:1 for wagons). An optional 3.08 axle was also available for 350 powered Caprices. The 305 V8 engine received an aluminum intake manifold which reduced engine weight by 35 pounds. A larger brake booster was also added to help reduce braking effort. New options included a steel sliding moonroof and 40-channel CB radio built into the AM/FM radio.
