I read on the innerweb that our cars are not consider a muscle car. Being that a muscle car means a straight line car. A mustang was considered a pony car. Which means that its meant for turning on a road coarse. The only car built today as per the innerweb is the Dodge Hellcat and soon to be Demon. They were built with huge horse power and the demon will come with drag radials and a trans brake. It's only job is the 1/4 mile in comfort. These options are not found on a road coarse car and only a Drag car with muscle. The most important factor is that the Demon is street legal not like the Copo or Cobra Jet.
I cant remember where I read this but it wasn't that long ago.
What say the members..... Mustang = pony car or Muscle car. This means how it came from the factory. You can build anything into anything. My vote is the Mustang is the creator of the PONY CAR!!
I goggled Pony Car and this is what popped up....https://www.bing.com...26245D1680E8C02
In order to properly define the subject, you really must consider where this vernacular came from and the times in which it appeared in the pop culture. That is to say, you need to examine the terms Pony Car and Muscle Car in proper context.
The term "pony car" was coined by an automotive journalist in 1966 or 1967 (I forgot who) when General Motors, Chrysler and eventually American Motors copied the Ford Mustang over the next few years. Pony Car meant a car like the Mustang - specifically long hood, short deck, and sporty; just look at the Camaro, Firebird, Barracuda, Javelin, AMX, and Challenger. You could also cite the unibody construction, floor mounted shifter, front bucket seats virtually no room in the back, and an array of performance options. Seriously, it's the sincerest form of flattery: 50+ years after the Mustang's introduction it's still the sales leader in its segment and they're still trying to copy it. Some would even add the 1970-81 Datsun 240-60-80Z to the list imitators, as well as the recent Hyundai Genesis. They're all Pony Cars.
The term "muscle car" was coined to describe the 1949 Oldsmobile Rocket 88 - so named for it's 303 cubic inch over-head valve engine (which developed a whopping 135 hp and 283 ft-lbs of torque). The car was reasonably light and fast for it's day. And it was an entirely American phenomenon; there were no European cars like it. They were generally a performance variant of a mid-sized 2-door model, at an affordable price - compared to expensive "sports cars" and "GT cars". One might cite the increasing popularity of Stock Car racing duing the 1950s (thank you Bill France for recognizing the need and creating NASCAR). Whether racing pushed the development of more and more powerful engines - or - the development of more and more powerful engines supported / drove the country's increasing fascination with stock car racing, the Big Three (GM, Ford, Chrysler) had started to produce performance models by the end of the 1950s, and continued to escalate into the 1960s. Consider Ford's 352 CID engine introduced in 1958 had sparked the whole "FE" engine family and was bored and stroked to 427 CID by 1963. A similar thing was happening with Chevy, Pontiac, Oldsmobile, Buick, Dodge, Chrysler, and Plymouth. And let's not forget the Chrysler Hemi was created in the 1950's as well. These larger and more powerful motors . Muscle cars were often packaged around an engine. Typically people think of the following cars as Muscle Cars: Chevelles / Malibus, Skylarks (Gran Sport Stage I), Cutlass (442), Tempest (GTO)s, Chargers, Satellites (GTX), Dusters (Demon), Falcon, Fairlanes, Torinos, and Montegos They're all Muscle Cars.
Where I think the links you've suggested are wrong is the notion that a Mustang can't be a Pony Car AND a Muscle Car at the same time. It can; it all depends on how it's equipped. Consider the 1969 Mustang: the Boss 429 w/Boss 429, Mach I w/428CJ are definitely Muscle Cars. Yet a Mach I with a 351W or coupe with a 6-cylinder probably wouldn't be cast as a muscle car. And a '69 Boss 302 was specifically designed for road racing, . Similarly, a big-block Camaro, Firebird, Challenger, Cuda, Charger, Javelin, Cutlass, Skylark or a Corvette would also have to be considered Muscle Cars. And yet, we would call any Camaro, Firebird, Challenger, Cuda, or Javelin a Pony Car.
