The short answer
The Toyota Prius gets better combined gas mileage than the Hyundai Elantra Hybrid. The base Prius LE is EPA-rated at 57 mpg combined versus the Elantra Hybrid Blue's 54 — a 3-mpg edge. But the Elantra Hybrid Blue actually wins on the highway, rating 58 mpg to the Prius LE's 56. The Prius leads overall.
How does the Prius compare to the Elantra Hybrid on real-world fuel economy?
The Toyota Prius. The 2025 Prius LE FWD is EPA-rated at 57 mpg combined, beating the Hyundai Elantra Hybrid Blue's 54 mpg by 3 mpg. The Prius leads combined at every comparable trim and peaks at 57 mpg — one of the highest combined ratings of any non-plug-in car on sale in the U.S. today.
| 2025 trim & drivetrain | City | Hwy | Combined |
|---|---|---|---|
| Toyota Prius LE FWD | 57 | 56 | 57 mpg |
| Toyota Prius XLE/Limited FWD | 52 | 52 | 52 mpg |
| Hyundai Elantra Hybrid Blue | 51 | 58 | 54 mpg |
| Hyundai Elantra Hybrid SEL/Limited | 49 | 52 | 50 mpg |
Both use proven full-hybrid systems, so neither is an outlier — the Prius's edge comes from its lighter, aero-tuned hatchback body. EPA combined ratings are published at fueleconomy.gov for the Prius and the Elantra. Note that Hyundai discontinued the standalone Ioniq hatchback after 2022, so the Elantra Hybrid is now its direct Prius rival. For the bigger question of whether the hybrid premium pays off, see our guide on whether a hybrid is worth it.
Does the Elantra Hybrid beat the Prius on highway fuel economy?
Yes, in one matchup. The Hyundai Elantra Hybrid Blue is EPA-rated at 58 mpg highway, edging the Prius LE's 56 mpg by 2 mpg. It's a genuine reversal: the Prius wins city and combined, but the lightweight Elantra Hybrid Blue takes the highway crown — a useful detail for high-mileage commuters.
The reason is tuning, not magic. The Elantra Hybrid pairs a 1.6L engine with a six-speed dual-clutch transmission that holds efficient gearing at cruising speed, while the Prius's strength is its electric assist in stop-and-go city driving. Step up to the Elantra Hybrid SEL or Limited and highway mpg falls to 52, below the Prius. The Prius PHEV (Prime) is a separate plug-in product rated in MPGe and isn't part of this gas-hybrid comparison. Highway figures are listed on the Elantra's fueleconomy.gov page.
How does adding AWD affect the Prius's fuel economy?
It costs about 3 mpg combined. The 2025 Prius LE FWD is EPA-rated at 57 mpg combined, while the Prius LE AWD drops to 54 mpg — the same combined figure as the front-drive Elantra Hybrid Blue. On the XLE and Limited, AWD falls from 52 to 49 mpg combined. The Elantra Hybrid offers no all-wheel-drive option.
| 2025 Prius trim | City | Hwy | Combined |
|---|---|---|---|
| Prius LE FWD | 57 | 56 | 57 mpg |
| Prius LE AWD | 53 | 54 | 54 mpg |
| Prius XLE/Limited FWD | 52 | 52 | 52 mpg |
| Prius XLE/Limited AWD | 49 | 50 | 49 mpg |
That 3-mpg penalty buys all-weather traction the Elantra Hybrid simply can't match at any trim. Even the AWD Prius LE matches the best front-drive Elantra Hybrid on combined mpg. Drivetrain ratings are pulled from the Prius's fueleconomy.gov listing.
How much less does each car cost to fuel per year?
The Prius LE is the cheapest to fuel. At 15,000 miles a year and $3.50 a gallon, the 57-mpg Prius LE costs about $921, the 54-mpg Elantra Hybrid Blue about $972, and the heavier Prius XLE about $1,010 — a spread of roughly $90 a year between the best and worst here. All four are remarkably cheap to run.
| Model (combined mpg) | Gallons / yr | Fuel cost / yr |
|---|---|---|
| Prius LE FWD (57) | ~263 | ~$921 |
| Prius LE AWD (54) | ~278 | ~$972 |
| Elantra Hybrid Blue (54) | ~278 | ~$972 |
| Prius XLE/Limited FWD (52) | ~288 | ~$1,010 |
| Elantra Hybrid SEL/Limited (50) | ~300 | ~$1,050 |

Which hybrid is worth buying if fuel savings matter most?
For the lowest fuel bill, buy the Prius — 57 mpg combined and roughly $921 a year, the best here, plus optional AWD. Buy the Elantra Hybrid if you drive mostly highway miles and want a lower entry price, giving up just 3 mpg combined (54) while actually beating the Prius on the highway at 58 mpg.
- Pick the Prius if: you want the highest combined mpg, optional all-wheel drive, or the most hatchback cargo space.
- Pick the Elantra Hybrid if: you commute mostly on highways, prefer a traditional sedan, and want a lower sticker price for nearly identical fuel costs.
