13 Discontinued Muscle Cars That Would Be Popular TodayMuscle car discussions often concern vehicles from the 1960s and 1970s, the so-called Golden Age of high-powered, rear-wheel drive cars with a Detroit V8. Names like GTO, Chevelle, and Barracuda are just a few from the long list of discontinued American muscle cars. Since then, there has been a steady, if less intense, stream of muscle cars on the market. The Ford Mustang is the only remaining American-made V8-powered RWD factory hot rod. Which begs the question: of all the discontinued American muscle cars, would any still be popular today? Given the current spotlight on battery-powered cars, hybrids, and turbocharged small-displacement mills, it may seem like muscle cars are a thing of the past. That is, until you realize that Ford and Chevy continue to build V8 powertrains across their respective lineups and that Chrysler is in the process of reviving its famed Hemi V8. The appetite for the iconic rumble of a naturally aspirated V8 clearly remains, meaning there's room to bring some of these muscle car legends back from the dead. That said, this look at 13 of our top choices for this type of resurrection does include some non-traditional examples of the American muscle car, but we think you'll agree they deserve another run.2012 Chrysler 300C SRT-8Chrysler's late, great 300C SRT-8 is another discontinued American muscle car that appeared, to the untrained eye, to be simply an elegant full-size sedan. However, car nerds know this 300C to be a wolf in sheep's clothing with its naturally aspirated 6.4L Hemi V8 making 470 horsepower and lb-ft of torque. An absolute rocket, the big Chrysler could do the 0-60 sprint in 4.3 seconds and run up to 175 mph. Perhaps the most impressive part was its roughly $48,000 sticker price, a serious bargain compared to the period M5 with a $94,000 price point.And the 300C SRT-8 was more than just a big motor, with performance upgrades that included adaptive dampers, bolstered front sport seats, and fat 20-inch rubber. Luxury was ample thanks to available heated and cooled seats, Nappa leather, and a Harman Kardon audio system. As for popularity today, take a look at the existing Chrysler portfolio and you'll find exactly one vehicle for sale. For fans of this long-running American brand, a modern 300C would be irresistible, and with the 540-hp variant of the corporate Hurricane powertrain, it could still be considered a muscle car.
