The Environmental Protection Agency has published revised fuel economy numbers for the 2022 Corvette Stingray.
The 2022 Corvette Stingray has an EPA-estimated fuel economy rating of 16 mpg city, 24 mpg highway and 19 mpg combined. The 2021 Corvette, for comparison, had an EPA fuel economy rating of 15 mpg city, 27 mpg highway and 19 mpg combined.
| Model Year | City MPG | Highway MPG | Combined MPG |
|---|---|---|---|
| 2021 | 15 | 27 | 19 |
| 20221 | 16 | 24 | 19 |
- Ratings based on Corvette Stingray equipped with Z51 Performance Package.
The reason for the drop in highway fuel economy is due to the popularity of the Z51performance package, explained Trevor Thompkins, Car, Performance and Motorsports Communications for Chevrolet.
“The EPA fuel economy numbers are based on which package is most popular. For 2021, Corvette Stingrays equipped with Z51 accounted for nearly 70 percent of Corvettes sold, because our customers are looking for the highest level of performance,” Thompson said in an emailed statement. “Due to [the] success of the Z51 package, we will be reporting model year 2022 EPA fuel economy numbers based on the Z51-equipped Corvette Stingray’s results – 16 city, 24 highway and 19 combined. These numbers are 3 MPG lower on the highway than 2020 and 2021 Corvettes because fuel economy for those model years were drawn from non-Z51 Stingrays.”
“The 2022 Corvette Stingray shows a 1 MPG gain in the city even with Z51 included because all 2022 Corvettes feature an upgraded direct injection fuel system, improved engine calibration and an enhanced Active Fuel Management range,” he added.
In short, this means highway fuel economy has actually remained the same, but the new, lower number is based on the Z51-equipped model instead of the base model. If the base model was used to get EPA fuel economy figures, the highway fuel economy rating would remain the same.
We covered the engine calibration changes for the 6.2L LT2 V8 in a previous article. The changes include modified engine management software, along with revisions to the fuel delivery and active fuel management systems. These changes were made to ensure the mid-engine sports car is able to meet increasingly stringent EPA emissions and fuel economy standards. Just like for 2021, the 2022 Corvette Stingray is rated at 495 horsepower and 470 pound-feet of torque when equipped with the optional Performance Exhaust system.
Production of the 2022 Corvette Stingray began on September 6th, 2021. In addition to the aforementioned engine updates, the 2022MY also introduces a new C8.R GTLM Championship Edition, which celebrates Corvette Racing’s championship-winning 2020 IMSA season with Corvette C8.R-inspired graphics and other exclusive equipment. Additionally, the Zeus Bronze Metallic, Shadow Gray Metallic, and Sebring Orange Tintcoat colors will be indirectly replaced by Hypersonic Gray Metallic, Amplify Orange Tintcoat, and Caffeine Metallic. The car has also dropped the Pewter painted wheel option and added a new available low profile rear spoiler.

my Z51 equipped 2021 seems to get around 22mpg average. but i could do better.
the V4 symbol on dash goes green even when highway cruising at 80mph. and
instant mpg displayed goes up very high. I like that. I wish it went to V4 mode at stoplights,
and I wish V4 mode was a button I could push, instead you play with the throttle hoping you
can get the car to slip into V4, and try and keep it there.
I have 5500 miles on the car so far, it is fantastic.
I imagine that performance and engine cleanliness are part of having the V8 “on” more than it is. I would like a button to press when I’m going down hills for he V4 option. It would likely add a mile per gallon. If the button is pressed, there should be a timed return to V8, as one option and if another mode is pressed, then it remains V4 until the engine is shut off, or until the driver puts it back in V8 mode.
One would think that when going downhill fuel management all but cuts off the fuel anyway – except for just enough to keep the engine running. But honestly, isn’t a Corvette with active fuel management (a 4-cylinder mode) an oxymoron to begin with. If I recall correctly, the C7 ZR1 does not have AFM.
My 2021 Z51 consistently gets 26 – 28 MPH with “mostly” highway driving – even with a few spirited spurts and a short detour through town. Always been impressed with the mileage. My Z51 is BEFORE the 2021 EPA tweak and “My Mode” is configured with the exhaust wide open if that makes a difference. On a totally highway trip without traffic I consistently get 28 – 29. So at least in my case, the numbers are actually better than provided.
