Anatomy of the Musclecar

"Make 'em smaller," said the federal government. "Make 'em cleaner," said the environmentalists. "Make 'em cheaper," said the financial guys. "Make 'em get better gas mileage," said the energy guys. So Detroit responded and built smaller, lighter, lower-priced and more-economical cars. Only problem was, nobody bought 'em!


About the only thing you could predict for this new crop of smaller American cars is that they were gonna get bigger, and they did. But while they were on the way to growing up like school kids, passing from compacts to intermediates, a strange but predictable thing happened. A couple of really sharp guys working at Pontiac got a bright idea: Why don't we take one of those "really big" 400 cubic-inch engines we're building for our "really big" full-size cars and put it into one of these new, smaller cars? This wasn't a new idea—the hot-rod community had been doing it for years. The formula was very simple: "Stuff a big engine into a small car and it's gonna really go." And it did.


Thus was born the first factory-built American musclecar, the 1964 Pontiac GTO. It didn't take very long to catch on, and soon every manufacturer had a musclecar of its own, created simply by stuffing one of their big engines from their full-size cars into one of their new intermediates. Falling in line behind the Pontiac GTO were the Chevy Chevelle Super-Sport, the Olds 442, the Buick Gran Sport, the Plymouth GTX and Road Runner, the Dodge R/T and Super-Bee, the Ford Fairlane GTA and Torino, the Mercury Comet Cyclone and the AMC Rebel Machine.


Meanwhile, another group of small but sportier looking cars were coming up on the outside, sparked by the Ford Mustang. They were called ponycars. Again, it didn't take long for most every manufacturer to follow up with its own ponycar. The Chevy Camaro, the Pontiac Firebird, the Mercury Cougar, the Dodge Challenger, the Plymouth 'Cuda and the AMC Javelin all emerged. While they eventually became just as fast and just as capable, they aren't true musclecars.


My definition: "A musclecar is a smaller, lighter-weight, intermediate-sized car originally designed for economy but subsequently powered by an engine built for a heavy full-sized car." No wonder they went fast! No wonder they created a culture. No wonder they are a part of today's treasured collectibles.
