American Muscle: A Partial History


The American muscle car, introduced in 1949, is an essential component of the car industry.  In response to the sudden demand for faster cars at this time, Oldsmobile débuted its Rocket 88.  The Rocket 88 had a high-compression overhead valve V8 in a lightweight Oldsmobile body.  The body was the same platform as the Oldsmobile 76, which was designed for a six-cylinder engine.  This combination created the definition of a muscle car: a car with a light body and a powerful engine.  The Rocket 88 dominated the NASCAR circuit in 1950, escalating the craze for speed.


The need for fast cars started with prohibition in the 1920s.  Moonshiners and bootleggers wanted to be able to outrun police vehicles, so they started modifying their cars.  As the years passed and prohibition ended, the Southern moonshiners became infamous for their modified cars.  The moonshiners transformed their cars due to the demand for speed, handling, and cargo capacity.  By the 1940s, these cars progressed to be more efficient.  The moonshining business was not nearly as profitable as it was during prohibition; the moonshiners started to use their cars for racing.  These remodeled cars dominated the street racing circuits and thus inspired the Oldsmobile Rocket 88.

New Innovation

The muscle car industry took off over the 1950s.  The Rocket 88 was soon surrounded by competition.  Two significant contributions to the industry were the Chrysler Corporation Hemi and the Chevrolet small-block V8.  A Hemi is a series of V8 engines with a hemispherical combustion chamber originally made by Chrysler in 1951.  A hemispherical combustion chamber basically has the valves of the cylinders facing each other improving the engine’s airflow capacity and yielding a higher power output.  Chrysler coined and marketed the term “Hemi,” but other automakers have developed similar designs.  The Hemi was introduced the 1955 Chrysler C-300, giving it 300hp and its historic name.  The C-300 became known as “America’s Most Powerful Car.”

The small-block V8, made in 1955, was essential for developing lightweight muscle cars.  The engine became a GM corporate standard and was used in their cars for 50 years.  Throughout the 1950s, American automakers continued to make groundbreaking contributions to performance cars, such as Chevrolet’s mechanical fuel injection.  Big, powerful engines in lightweight cars resulted in incredible speed but poor handling.  Compellingly, drag racing grew in popularity.

The Golden Age

In 1964, Pontiac released the Tempest GTO ushering in the Golden Age of muscle cars.  First of all, GTO was an abbreviation for Gran Turismo Omologato or translated Grand Tourer Homologation, which basically meant the car was approved for races.  The GTO had both the appeal and the muscle to make it a benchmark in muscle car history.  It deceptively looked like a simple Tempest and offered an option that bypassed a GM rule of producing midsize cars with engines greater than 330 CID.  (CID stands for cubic inch displacement and is used to measure the volume of an engine’s cylinders and combustion chamber.  This unit of measurement is no longer used today, 330 CID engine equals 5.4 liters.)  At the low price of $3,200, the Pontiac GTO was affordable to younger people.  In its first year, Pontiac sold over six times as many cars as predicted.  In the same year, Ford introduced the Thunderbolt with a staggering 427 CID.  It was deemed dangerous to drive, and although only 127 were made, it is still remembered as an excellent muscle car.

The Ford Mustang was also released in 1964.  The Mustang came with sharp looks, plenty of options, and a low price, but deficient power.  As a result, it created a new market: the pony car.  Pony cars are often confused with muscle cars because they look similar and some have power.  But like the GTO, looks can be deceiving and the power of a pony car is to a great extent inferior to that of a muscle car.  A few well-known pony cars are the Chevrolet Camaro, Dodge Challenger, and Plymouth Barracuda.  Contrary to popular belief, the Corvettes of the 1960s era were not considered muscle or pony cars.

In 1967, Ford upgraded the Mustang from a small-block to a 390 CID big-block engine.  Ford impressively had a 428 CID engine made by Carroll Shelby.  Other automakers turned out competitive cars like the Chevrolet Camaro and the Pontiac Firebird.  Plymouth tried to diversify by making a budget muscle car: the Road Runner.  Soon the market became saturated and the automotive companies started losing money.

In 1968, federal safety and emissions rules came into play.  There was also a new safety lobby led by attorney Ralph Nader.  These influences and regulations could have threatened the industry; yet with the 70s steadily approaching, the muscle car industry was at its peak.  The Camaro, Mustang, and Firebird were being spectacularly upgraded.  The GTO dropped in price and was presented with an entirely new look; hood scoops was prominent as well.  The Dodge Charger became exceptionally popular and the Daytona model was specifically famous for its wing.  GM returned to the pony car scene by redesigning the Camaro and Firebird.  The muscle and pony car industry was booming at the end of the decade, but a crash was imminent.

The Death of the Muscle Car

The early 70s brought about change in the auto industry.  The government put in new emission limits and carmakers started producing engines that ran on low-lead fuel.  Manufacturers detuned the powerful engines of the 1960s to meet the government standards.  New federal motor vehicle safety standards forced automakers to change the bumpers to heavier, sturdier metals, adding weight and further cutting performance.  These new restrictions significantly downgraded the performance of the muscle cars.

In 1973, OPEC cut oil exports to the United States.  This was the first oil crisis the United States ever faced and fuel shortages caused a shocking spike in gas prices.  Insurance companies cracked down on performance cars because the muscle cars of the late 60s were deemed unsafe.  This, coupled with inflation, made the price of owning a muscle car too high for the target market.  It made more sense for Americans to buy small compact cars, both imported and from Detroit.  The people who could afford muscles would not buy them due to lacking performance.  The devastatingly low demand for muscle cars led most of the big-block cars to be discontinued by 1975.  The cars that survived, like the Plymouth Road Runner, were dressed up and not built for speed.  Even the pony cars left the market – by 1974, only the Camaro and Firebird remained.  The Mustang had left the pony car market and evolved into a high-end compact.  Through the mid 70s, the Firebird dominated the ever shrinking market because of the new, improved handling and lack of competition.  Chevrolet noted Pontiac’s growth in Firebird sales and reinstated the Camaro Z-28 in 1977 after a two year withdrawal from the market.  Other pony cars hit the market, focusing on style rather than performance.  As the 1980s approached, manufacturers grew accustomed to federal regulations.  The third generation of the Mustang was released in 1979 with a new look and a V8 option.  The low-torque V8 sold well and it seemed as though performance cars would become popular once more.  But in the same year, America faced another gas crisis.  The crisis was over in 1982 creating a demand for performance cars once again.


With gas prices down, America was ready to be redefined as a country of speed.  New technology was emerging and Detroit started producing compact cars.  Engines that conformed to federal regulations accommodated small cars.  The advanced technology consisted of solid-state electronics and computer integration of spark timing, air intake, and fuel injection.  Muscle cars could now return because of safety, big but compliant engines, and more efficient production methods.  Ford and GM began turning out redesigned pony cars.  Ford was at the front of the pack with the Mustang and GM released the third-generation Camaro and Firebird.  These three cars had bigger engines than their 70s precursors, but they were still relatively small.  Car critics believed the Mustang was more popular because of its vintage look.  As the 80s and 90s progressed, the engines grew and the cars got faster.  In 1999, Camaro and Firebird even borrowed the aluminum-block V8 from the Corvette.  But in 2002, the two pony cars were discontinued and only the Mustang remained.

Modern Muscle

The 2000s was a time when the classics were finally brought back.  However, a notable failure was the Pontiac GTO.  The GTO was one of the most pivotal cars of the 60s muscle.  It had a dedicated following and was a truly successful car.  The 2004 GTO was a simple rear-wheel drive coupe with a powerful engine.  The mechanics of the car were superior, but it did not look American.  The GTO was redesigned to look like an import and people who would buy a GTO wanted it to look as American as the original.  The 2005 had hood scoops that did not help sales and in 2006 the car was discontinued.

In 1998, Mercedes-Benz took over Chrysler and in 2005 the Chrysler 300C was reborn.  The model had the legendary Hemi packed with 340hp.  The four-door sedan had a very American feel with a touch of German engineering, making this a well-rounded car.

In 2005, Mustang upgraded to its current generation.  With a beefy body style and a colossal engine, this Mustang is more of a muscle car than any of its predecessors.  The Dodge Charger and Challenger have also both made a comeback and both have a Hemi option.  Compared to their older models, the Challenger has the look and feel of a muscle car while the Charger simply has the power.  The Chevrolet Camaro is in the same class as the Dodge Challenger and the top of the line 2012 model can produce 580hp.  Dodge also resurrected the Dart, but only in name.  The new Dodge Dart, which is a 2013 model, is an economy car and does not resemble its older version at all.  A surprising addition to the new muscle cars is the Cadillac CTS-V.  Cadillac did not make any muscle cars in the 60s or 70s, but the CTS-V is currently the fastest sedan on the market with 556hp.
