Earlier this year, Chevrolet gave the Camaro a midcycle refresh. Most of the changes were cosmetic, but the 2019 Camaro got a few functional updates, as well. The reworked front end was said to make the car more aerodynamic, for example, and the SS got the ZL1's 10-speed automatic transmission. You'd think those changes wouldn't hurt gas mileage, but you'd be wrong.

According to the Environmental Protection Agency's official figures, the 2019 Chevrolet Camaro SS with the 10-speed auto is rated at 16/27/20 mpg city/highway/combined. Fifteen years ago, that was the kind of gas mileage you got out of a V-6 family sedan, so it's seriously impressive to see a 455-hp sports coupe with a 6.2-liter V-8 does so well. But the 2018 Camaro SS with an eight-speed auto actually did slightly better, earning a city rating of 17 mpg.

The automatic V-6 is also interesting. Chevrolet kept the same transmission, and both the city and highway numbers stay the same, but for some reason, its combined rating is 1 mpg worse than in 2018. Choose the manual V-6, and your combined rating stays the same, but highway economy drops slightly. The automatic ZL1, however, did manage to increase its combined rating from 15 to 16 mpg. The gas mileage for the rest of the Camaro lineup stayed the same.
