The EPA posted official fuel economy estimates for Chevy’s latest pony car. They show minor drops in fuel economy, but surprising drops nonetheless considering the car’s updates.

Highway fuel economy stays constant at 27 mpg

For 2019, the Camaro SS with a six-speed manual transmission sees highway fuel economy drop from 25 mpg to 24 mpg. It is the SS models equipped with the automatic that surprise the most. Even with 10 speeds, the Camaro SS will return 16 mpg city compared to 17 mpg for the 2018 model with an eight-speed automatic.

Chevy said at the 2019 Camaro SS’s debut that the redesigned face improves aero and cooling functions while decreasing drag. One would think a more slippery Camaro would make for a slightly more fuel efficient Camaro, too.

We don’t have an explanation other than the EPA perhaps changed its testing methods, which resulted in thirstier Camaros for 2019. But, the EPA hasn’t made any changes public after signaling it would change methods for the 2017 model year. The 2.0-liter turbo-4 and Camaro ZL1 with its supercharged 6.2-liter V8 don’t see any changes to their fuel economy numbers, however.

Buyers looking at a Camaro SS, or any Camaro model, likely aren’t too worried about pain at the gas pump and a single mpg drop in various areas are minimal at best.
