The 2021 Hyundai Elantra Hybrid Blue gets 54 MPG combined, and that’s great. This isn’t some hyper-specialized eco-mobile, but a mainstream compact sedan with room for five, a decent trunk, and a price that won’t break the bank. Its fuel economy significantly undercuts many subcompacts, achieved in a car that doesn’t feel uncomfortable. The Elantra Hybrid Blue appeals directly to the practical buyer who wants minimal running costs without sacrificing everyday usability.

City and highway performance

The Elantra Hybrid Blue works well in both city and highway driving, achieving an EPA-rated 53 MPG in the city and 56 MPG on the highway. This near-identical performance reflects the strengths of its hybrid powertrain. The 1.6L 4-cylinder engine and electric motor work to optimize fuel consumption in all conditions. In the city, the electric motor handles much of the low-speed acceleration and stop-and-go driving. On the highway, the engine takes over, but the electric motor still provides assistance during acceleration and cruising, preventing the engine from working too hard. Fuel savings are significant, no matter how you drive.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Hyundai Elantra Hybrid Blue at exactly $800. This figure is based on driving 15,000 miles per year and using national averages for fuel prices. Actual costs may vary depending on individual driving habits and local fuel prices, but $800 paints a clear picture: this car is exceptionally cheap to run. It’s a number that resonates with budget-conscious buyers, especially those who rack up significant mileage commuting or for work. This low annual fuel bill allows owners to put funds to other areas of life, knowing they are getting the most value for every dollar invested in transportation.

Real-world expectations

While the EPA estimates are a good benchmark, real-world fuel economy often differs. The Elantra Hybrid Blue consistently delivers impressive figures in real-world testing. Many owners report achieving MPG numbers very close to the EPA estimates, some even exceeding them with careful driving. Variables will always exist: aggressive driving, frequent rapid acceleration, high speeds, and extreme weather can all negatively impact fuel economy. However, a conscientious driver behind the wheel of the Elantra Hybrid Blue can reasonably expect to see MPG figures well above the average for other compact sedans.

How it compares

The Elantra Hybrid Blue stacks up well against its competitors. The Toyota Corolla Hybrid LE achieves a similar 52 MPG combined. The Honda Insight EX is rated at 52 MPG combined as well. The Elantra Hybrid often costs less than its rivals, making it a good option for budget-minded buyers. Even non-hybrid rivals struggle to compete. A standard Toyota Corolla’s combined fuel economy typically hovers in the low 30s. The Elantra Hybrid Blue offers hybrid efficiency in a mainstream package at a price point that makes sense for everyday drivers. For all Hyundai fuel economy data, there’s a lot to choose from in their lineup; the ELANTRA MPG across all years shows a commitment to strong numbers.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the Elantra Hybrid Blue. Avoid slamming on the accelerator, as this forces the engine to work harder and defeats the purpose of having the electric motor assist. Ease into acceleration, allowing the electric motor to provide the initial boost.

Use the regenerative braking system to your advantage. Anticipate stops and start slowing down earlier, allowing the regenerative braking system to capture kinetic energy and recharge the battery. Avoid hard braking whenever possible. This will also extend the lifespan of your brake pads.

Maintain a steady speed on the highway. Cruise control can help on long trips, preventing unnecessary speed fluctuations that can drain fuel. Avoiding aggressive lane changes and erratic driving will also help optimize fuel economy.

Keep your tires properly inflated. Under-inflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the driver’s side doorjamb.
