These big V8, high power muscle cars can be very fuel efficient (in a relative sense, it’s not a Prius) at highway speeds. There’s so much power and torque available and with 6, 8 or 10 gear transmissions, you can have an overdrive gear where the engine is turning very low RPM at highway speeds. Combine that with fuel injection and an engine management computer and you can get really good mpg numbers.

In the old days, you’d have a 3 or 4 speed transmission with a carburetor and those would burn a lot of gas no matter what.

My first new car I bought was a 1987 Acura Integra. It would run around 4k RPM on the highway. It still got 30+ mpg on the highway but that’s a 1.6 liter engine that made 113hp. To have a 600+ hp Corvette almost make those kind of numbers tells you how far things have come in auto technology.
