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.
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.
The Chevrolet Impala is a full-size automobile built by the Chevrolet division of General Motors introduced for the 1958 model year. Deriving its name from the southern African antelope, Chevrolet's most expensive passenger model through 1965 had become the best-selling automobile in the United States, competing against the Ford Galaxie 500 and the Plymouth Fury when full-size models dominated the market. The Impala was distinguished for many years by its symmetrical triple taillights. The Caprice was introduced as a top-line Impala Sport Sedan for the 1965 model year becoming a separate series positioned above the Impala in 1966, which itself remained above the Bel Air and Biscayne. The Impala continued as Chevrolet's most popular full-size model through the mid-1980s. Between 1994 and 1996, Impala was revived as a muscular 5.7-liter V8–powered version of the Caprice Classic sedan. In 2000, the Impala was re-introduced again as a mainstream front-wheel drive full-size sedan. Consumer Reports gave the 2014 model the best rating in the large sedan category.
Ed Cole, Chevrolet's chief engineer in the late 1950s, defined the Impala as a "prestige car within the reach of the average American citizen."
Chevrolet Monte Carlo
A V6 engine is a V engine with six cylinders mounted on the crankcase in two banks of three cylinders, usually set at either a right angle or an acute angle to each other, with all six pistons driving a common crankshaft. It is the second most common engine configuration in modern cars after the inline four.
The V6 is one of the most compact engine configurations, shorter than the inline-4 and in many designs narrower than the V8. Owing to its compact length, the V6 lends itself well to the widely used transverse engine front-wheel drive layout. It is becoming more common as the space allowed for engines in modern cars is reduced at the same time as power requirements increase, and has largely replaced the straight-six engine, which is too long to fit in many modern engine compartments. The V6 engine has become widely adopted for medium-sized cars, often as an optional engine where an inline-4 is standard, or as a base engine where a V8 is a higher-cost performance option.
GM High Value engine
The Chevrolet Monte Carlo was an American-made two-door coupe introduced for model year 1970, and manufactured over six generations through model year 2007. It was marketed as a personal-luxury coupe through most of its history, with the last model version being classified as a full-sized coupe. When it was discontinued in 2007, it had outlived many competitors that were either discontinued many years earlier or changed in concept to either a four-door sedan or small sport coupe.
The Monte Carlo endured six design generations. The first four (1970–72, 1973–77, 1978–80 and 1981–88) were of a rear-wheel-drive, V8-powered (V6 available beginning in 1978) coupe style, utilizing separate body-on-frame construction. The later rear-wheel-drive generations bucked the trend of unit-body construction, along with smaller engines, that became more prevalent in the early 1980s as automakers downsized their vehicle lines to meet increasing stringent fuel-economy regulations in the aftermath of two energy crises that led to gasoline shortages and skyrocketing pump prices in 1973-74 and 1979-80. Despite those trends, the Monte Carlo remained a popular seller and even regained the SS version (initially offered for 1970-71 with 454 cubic-inch V8) from mid-1983 to 1988 with a high-performance 305-cubic-inch V8.
The High Value engine family from General Motors is a group of Cam in Block or "Overhead valve" V6 engines. They use the same 60° vee bank as the 60° V6 family they are based on, but the new 99 mm (3.9 in) bore required offsetting the bores by 1.5 mm (0.1 in) away from the engine centerline. These engines (aside from the LX9) are the first cam in block engines to implement Variable Valve Timing, and won the 2006 Breakthrough Award from Popular Mechanics for this innovation. For the 2007 model year, the 3900 engine features optional displacement on demand or "Active Fuel Management" which deactivates a bank of cylinders under light load to increase highway fuel economy. It was rumored GM would produce a 3-valve design, but that never came to be. These engines are produced primarily at the GM factory in Tonawanda, New York. The assembly line for this engine was manufactured by Hirata Corporation at their powertrain facility in Kumamoto, Japan.
As of the 2012 model year, GM no longer sells these motors in any US market vehicles.
