The Death of Muscle Cars
In many ways and for many reasons,
The decline was perhaps inevitable. Demand for big, fast, thirsty cars dried up as rising gas prices and hefty insurance premiums had many buyers looking at thriftier, more affordable
While these harsh realities compromised all cars to some degree, muscle machines fared the worst by far. They did, after all, have the most to lose.
Signs of loss appeared as early as 1971, when General Motors' engines and some Chrysler Corporation mills were recalibrated to run on regular-grade gas instead of premium. That same year, GM switched its advertised engine ratings from gross figures to more-realistic net numbers, which made the power and torque losses look even worse on paper. American Motors, Chrysler, and Ford followed suit for 1972, when many engines were further detuned for newly required low-lead fuel.
Then, in October 1973, the Organization of Petroleum Exporting Countries (OPEC) drastically curtailed oil exports to the
Though the crisis lasted but a few months, it exposed
With all this, plus inflation-fueled "sticker shock" price increases, demand for muscle cars decelerated fast. By 1975, the casualty count included most big-block engines and such icon performers as the Buick GS, Chevrolet Chevelle Super Sport, Dodge Charger R/T and Super Bee, Ford Torino Cobra, Mercury Cyclone Spoiler, and Plymouth GTX. Even the hallowed GTO wasn't spared, reduced for 1974 to a largely dress-up option for

Pony cars all but disappeared, with only the Chevy Camaro and Pontiac Firebird left to carry the torch after '74. Ford's Mustang, the original pony, was super-sized for 1971-73, then re-imagined as a high-class economy compact. This Mustang II was fortuitously timed and very popular, but made Mustangers wince even after an optional 302 V-8 returned after a year's absence. Mercury's Cougar? Morphed into obscurity a luxury intermediate.
But it wasn't all bad news. Despite the increasingly hostile climate, a few '70s cars did offer performance kicks, if not the tire-shredding thrills of old.
Heading the list of performance survivors were the "mini-muscle" compacts that began appearing in the early '70s. Sometimes called "insurance beaters," they offered satisfying go from torquey small-block V-8s yet cost far less to buy and operate than '60s-style midsizers.
For example, the 1971-73 Plymouth Duster 340 and Dodge Demon/Dart Sport 340 offered up to 240 net bhp, plus nifty fastback coupe styling, eye-grabbing colors, and enough tape stripes and black accent paint for a Trans-Am race car. A 360 V-8 came in for '74, but for easier emissions tuning, not extra power. American Motors, Ford, and GM offered their own sporty compact confections, and though none sold that well, they brightened up an increasingly gloomy market.
So, too, the top-performing Pontiac Firebirds. Though strangled no less than other hot cars, the Firebird Trans Am and 400 bucked the market by posting higher year-to-year sales for 1973 and '74 -- just as the gas crisis was raging. Of course, it helped they had little competition by then. Still, such surprisingly strong sales convinced product planners all over
In any case, Chevy took the hint and reinstated the Camaro Z-28 for 1977 after a two-year furlough -- and with a new emphasis on handling. GM also kept its pony cars going with remarkably adept updates to their basic "19701/2" design, meeting federal safety standards with savvy style, not short-cut clumsiness.
Meantime, the economy fast pulled out from its gas-crisis doldrums, and the 1980s approached with signs that
Perhaps the most encouraging marker was a clean-sheet 1979 Mustang and companion Mercury Capri: roadable, slick-looking new-think pony cars that admirably reconciled many conflicting demands of the day. The base engine was an economy-minded four with just 88 net bhp, but you could order 140 horses with either a turbocharged four or that old standby,
Then, in spring 1979, came a second gas crunch that had buyers scurrying back to smaller cars again. Though
On the next page, you'll see that the answer to both questions was yes. People still wanted hot cars, but not the kind their fathers knew. Times had changed. But
