The 2020 Hyundai Sonata Hybrid Blue 2.0L gets 52 MPG combined, a significant achievement for a mid-size sedan that offers both impressive passenger space and modern technology. It’s not a sporty, head-turning machine, it’s a very rational choice for buyers prioritizing fuel efficiency. People who drive long highway miles for work, or families wanting a comfortable and economical daily driver, are the Sonata Hybrid Blue’s target demographic.

City and highway performance

The Sonata Hybrid Blue excels in both city and highway driving. The EPA estimates 50 MPG in the city and 54 MPG on the highway. This narrow range shows the well-integrated hybrid system and the car’s ability to efficiently manage power delivery across various driving conditions. The transitions between electric and gasoline power are barely noticeable, contributing to a refined driving experience. This close MPG range reflects how efficient this car can be under different user cases. You are not penalized for driving in the city compared to the highway.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Hyundai Sonata Hybrid Blue at $850. This is based on driving 15,000 miles per year, using national average fuel prices. For drivers exceeding this mileage, or facing higher local fuel costs, the savings compared to a conventional gasoline vehicle become even more substantial. Keep in mind that future swings with gasoline prices could skew this estimated number, but the current yearly cost of fueling this vehicle is just $850.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy can vary depending on driving habits, terrain, and weather conditions. The Sonata Hybrid Blue’s hybrid system is sensitive to driving style. Gentle acceleration and smooth braking will maximize the amount of time spent in electric-only mode, yielding the best possible fuel economy. Aggressive driving will force the gasoline engine to contribute more frequently, reducing overall efficiency. Monitoring the energy flow display can provide valuable feedback and encourage more economical driving habits.

How it compares

The 2020 Sonata Hybrid Blue faces stiff competition in the hybrid sedan segment. The Toyota Prius, a perennial fuel-economy champion, achieves 52 MPG combined in its LE Eco trim. The Honda Insight, another strong contender, offers 52 MPG combined in its base LX trim. The Hyundai Ioniq Blue, while slightly smaller, boasts an impressive 59 MPG combined. The Sonata Hybrid Blue buyer isn’t just chasing the highest number, they are seeking a blend of efficiency, comfort, and space in a traditional sedan form factor. Choosing the Sonata Hybrid Blue is trading some MPG to move into a larger, more conventional sedan. For a look at all Hyundai fuel economy data, be sure to check out our other pages.

Tips to maximize efficiency

Anticipate traffic flow and avoid sudden acceleration or braking. The Sonata Hybrid Blue’s regenerative braking system captures energy during deceleration, which helps recharge the battery and extend the electric driving range. By maintaining a consistent speed and anticipating stops, you can maximize the amount of energy recovered and minimize fuel consumption.

Use the car’s Eco mode. This setting optimizes throttle response, transmission shift points, and air conditioning operation to prioritize fuel efficiency. While Eco mode may slightly reduce performance, the fuel savings can be significant, especially during city driving. Don’t be afraid to switch between drive modes; use Eco mode when the benefit outweighs the performance hit.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the doorjamb sticker inside the driver’s side door. Doing so will not only improve fuel efficiency, but improve handling and tire life.

Minimize the use of accessories like air conditioning and heated seats. These features draw power from the battery or engine, increasing fuel consumption. Use them sparingly, especially during short trips. Preconditioning the cabin while plugged in can help minimize the load on the engine and battery once you are on the road.
Consider how the SONATA MPG across all years compares to other models.

Reduce unnecessary weight. Carrying extra cargo in the trunk or cabin can add to the vehicle’s overall weight, reducing fuel economy. Remove any unnecessary items to lighten the load and improve efficiency.
