The 2021 Hyundai Sonata Hybrid gets 47 MPG combined, making it a leader in fuel efficiency among mid-size sedans. It’s engineered for maximum fuel savings and low running costs. It’s primarily for commuters who prioritize long-term value and lower fuel costs over performance or brand recognition.

City and highway performance

The Sonata Hybrid’s 45 MPG city rating shows its efficiency in stop-and-go situations. The electric motor powers much of the low-speed driving, reducing gasoline use in urban driving. On the highway, it achieves an even better 51 MPG. This higher highway number comes from the engine’s optimized efficiency at cruising speed, and the hybrid system’s ability to blend electric assist with gasoline power. The automatic (AM-S6) transmission helps efficiency with its smooth shifts and optimized ratios for acceleration and highway driving.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Hyundai Sonata Hybrid at $950. This is based on driving 15,000 miles per year and using national average fuel prices. This cost will vary based on driving habits and gas prices, but it’s a good point of reference to understand potential long-term savings. Buyers see that the vehicle’s lower price and low fuel cost allow them to save money over time.

Real-world expectations

While the EPA estimates are helpful for comparison, real-world fuel economy always varies. Drivers of the 2021 Sonata Hybrid often report numbers close to the EPA estimates, especially with careful driving. Aggressive acceleration, high air conditioning use, and sustained high speeds can lower fuel economy. The hybrid system is generally reliable and delivers impressive mileage even under difficult conditions. You may even see higher numbers than the EPA ratings, particularly in suburban driving where regenerative braking recharges the battery.

How it compares

The Sonata Hybrid competes with other hybrid mid-size sedans, and its fuel economy is competitive. The Toyota Camry Hybrid, for example, gets 52 MPG combined in its LE trim, but 44 MPG in XLE and XSE trims. The Honda Accord Hybrid has a combined EPA rating of 47 MPG. While the Camry might have slightly better peak fuel economy in certain trims, the Sonata Hybrid has good affordability and efficiency, making it a solid choice for budget-minded shoppers. These buyers value comfort, practicality, and lower fuel costs.

Tips to maximize efficiency

Gentle acceleration and braking are important for maximizing fuel economy in the Sonata Hybrid. Letting the electric motor do more of the work, especially at lower speeds, reduces gasoline consumption. Anticipating traffic flow and avoiding sudden stops maximizes regenerative braking which recharges the battery.

Choose the right drive modes. “Eco” mode is suitable for everyday driving to maximize fuel efficiency. This prioritizes electric power and softens throttle response. Other drive modes can be selected when more power is needed.

Tire pressure has a large role in fuel economy. Make sure tires are inflated to the recommended pressure, typically found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, which lowers fuel efficiency.

Remove unnecessary weight from the vehicle. Extra cargo increases the car’s load, using more energy to accelerate. Removing unneeded items improves fuel economy.

Consider cruise control on the highway. Consistent speed can improve fuel efficiency, especially on longer trips. Pay attention to traffic and be ready to disengage cruise control when needed.
