With 55 MPG combined, the 2020 Hyundai Ioniq 1.6L 4-cyl is a fuel economy champion, and that’s the main reason it exists. People don’t buy this vehicle for fast acceleration, luxury, or eye-catching style. The Ioniq buyer wants the lowest fuel consumption possible, seeking dependable transportation that uses very little gas. The Ioniq delivers on that promise, providing hybrid efficiency in a practical, accessible package.

City and highway performance

The EPA ratings for the 2020 Ioniq are very similar across different driving conditions. Its 55 MPG city and 54 MPG highway figures are almost the same, which shows that the hybrid powertrain works well in both stop-and-go traffic and steady cruising. The 1.6L 4-cylinder engine, along with an electric motor and a responsive AM6 automatic transmission, work together to blend electric-only driving at lower speeds with gasoline power at higher speeds. This results in consistent fuel savings whether the Ioniq is in the city or on the highway.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Hyundai Ioniq 1.6L 4-cyl at $800. This is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Your actual fuel costs may be different depending on your driving habits, local fuel prices, and the amount of highway versus city driving you do. Still, the $800 provides a clear idea of how affordable the Ioniq is to fuel compared to regular gasoline cars or even some other hybrids.

Real-world expectations

EPA ratings offer a standard, but real-world fuel economy can change based on driving style, weather, and maintenance. The Ioniq’s hybrid system is tuned for efficiency, so it’s easier to get numbers close to the official figures. Drivers who accelerate and brake gently, and who maintain consistent speeds, will likely see results near or even above the EPA estimates.

How it compares

The 2020 Ioniq’s fuel economy makes it a strong competitor in the hybrid and efficiency-focused vehicle market. The Toyota Prius, a long-standing leader in hybrid efficiency, gets about 52 MPG combined in its standard trim. The Honda Insight, another good choice, delivers around 52 MPG combined. The Ioniq matches or exceeds the MPG figures of these competitors, making it a good choice for buyers who want the best fuel savings. For plug-in hybrids, remember the higher MSRP trims may reduce fuel savings over the vehicle’s life. Compare IONIQ MPG across all years before you choose.

Tips to maximize efficiency

Use the Ioniq’s Eco driving mode. This mode adjusts the engine for the best fuel efficiency by changing throttle response and transmission shift points. Use Eco mode in everyday driving to get more miles from each gallon.

Drive and brake smoothly. Quick acceleration and hard braking waste energy. Instead, accelerate gently and predict stops by coasting, which lets the regenerative braking system recapture energy and recharge the battery.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which lowers fuel economy. Check your tire pressure often and inflate your tires to the pressure on the driver’s side door jamb.

Reduce weight by removing unnecessary items from the trunk and passenger area to lighten the load.

Use air conditioning less often. Air conditioning uses a lot of engine power. When you can, use the ventilation system or open the windows to cool the car. If you need AC, set the temperature a few degrees higher and use the recirculation mode to reduce the system’s workload.
