PB, as the article states, gas shortages and Fed regs pretty much killed the muscle cars that held sway roughly from '61 to early '70's. But, once the industry learned how to mass produce OHC engines that were powerful and met Federal gas and emissions standards, a new muscle car era dawned--just not called "muscle cars." You can have your pick of dozens of mid- to mid-high-priced sedans that have 400-plus hp(net, not gross as in the '60's), but that get well over 20 mpg and are quiet and tractable on the road.

I yearned for a MoPar Hemi when I was younger. But my 2000 BMW M5 sedan has 423 hp@7400 rpm, a six-speed manual, Bilstein coilover suspension--and gets 28 mpg on some highway stretches.
