Muscle car is a term used to refer to a variety of high-performance automobiles. The Merriam-Webster dictionary defines muscle cars as "any of a group of American-made 2-door sports coupes with powerful engines designed for high-performance driving." A large V8 engine is fitted in a 2-door, rear wheel drive, family-style mid-size or full-size car designed for four or more passengers. Sold at an affordable price, muscle cars are intended for mainly street use and occasional drag racing. They are distinct from two-seat sports cars and expensive 2+2 GTs intended for high-speed touring and road racing. Developed simultaneously in their own markets, muscle cars also emerged from manufacturers in Australia, South Africa, the United Kingdom, and elsewhere. Also, it is widely believed by today's generation that the Nissan GTR is a muscle car.
A station wagon, also called an estate car and an estate, is an automotive body-style variant of a sedan/saloon with its roof extended rearward over a shared passenger/cargo volume with access at the back via a third or fifth door (the liftgate or tailgate), instead of a trunk lid. The body style transforms a standard three-box design into a two-box design — to include an A, B, and C-pillar, as well as a D-pillar. Station wagons can flexibly reconfigure their interior volume via fold-down rear seats to prioritize either passenger or cargo volume.
The American Heritage Dictionary defines a station wagon as "an automobile with one or more rows of folding or removable seats behind the driver and no luggage compartment but an area behind the seats into which suitcases, parcels, etc., can be loaded through a tailgate."
A mid-size car (occasionally referred to as an intermediate) is the North American/Australian standard for an automobile with a size equal to or greater than that of a compact. In Europe mid-sizers are referred to as D-segment or large family cars.
The automobile that defined this size in the United States was the Rambler Six that was introduced in 1956, although it was called "compact" car at that time. The mid-size class then grew out of the compacts of the early-1960s. For example, the Ford Fairlane was referred to at its introduction in 1962 as a compact intermediate because it was barely bigger than its close relative, the Falcon. General Motors' first entries in the class, such as the Oldsmobile F-85, Pontiac Tempest, and Buick Special were not mechanically related to the compact Chevrolet Corvair, but were similar in size.
The Chevrolet Chevelle was a mid-sized automobile produced by the Chevrolet division of General Motors in three generations for the 1964 through 1977 model years. Part of the GM A-Body platform, the Chevelle was one of Chevrolet's most successful nameplates. Body styles include coupes, sedans, convertibles and station wagons. Super Sport versions were produced through the 1973 model year, and Lagunas from 1973 through 1976. After a three-year absence, the El Camino was reintroduced as part of the new Chevelle lineup. The Chevelle also provided the platform for the Monte Carlo introduced in 1970. The Malibu, the top of the line model through 1972, replaced the Chevelle nameplate for the redesigned, downsized 1978 models.
The Chevrolet Chevelle Laguna is a mid-sized automobile produced by the Chevrolet division of General Motors for the 1973 through 1976 model years. Part of the GM A-Body platform, the 1973 Laguna series included coupes, sedans and station wagons. It was the top-line Chevelle series that year positioned above the Malibu. For 1974 through 1976 the car was produced as a one-model Laguna S-3 Coupe, the new-for-1974 Malibu Classic series taking the top-luxury series position. All Lagunas sported urethane front-ends which easily distinguished them from other Chevelles. NASCAR driver Cale Yarborough earned the first two of three consecutive Winston Cup Championships piloting a Chevelle Laguna.
Chevrolet El Camino was a coupe utility vehicle produced by the Chevrolet division of General Motors between 1959–60 and 1964-87. Introduced in the 1959–1960 model years in response to the success of the Ford Ranchero, its first run lasted only one year. Production resumed for the 1964–1977 model years based on the Chevelle platform, and continued for the 1978–1987 model years based on the GM G-body platform. Although based on corresponding Chevrolet car lines, the vehicle is classified and titled in North America as a truck. GMC's badge engineered El Camino variant, the Sprint, was introduced for the 1971 model year. Renamed Caballero in 1978, it was also produced through the 1987 model year.
In Spanish, El Camino means "the road".
