The 2018 Hyundai Ioniq Blue gets 58 MPG combined, a figure that immediately shows its purpose: high fuel efficiency. It’s not a performance hybrid, doesn’t offer all-wheel drive, and lacks a spacious cabin. It is, simply, a hypermiler’s dream in a practical, though unassuming, hatchback.

City and highway performance

The Ioniq Blue’s EPA estimates are 57 MPG in the city and 59 MPG on the highway. These numbers are consistent, reflecting the hybrid powertrain’s ability to use regenerative braking and electric assist in stop-and-go traffic, while maintaining efficiency at higher speeds. The 1.6L four-cylinder engine, coupled with the automatic (AM6) transmission, provides enough power for most driving. However, rapid acceleration isn’t the Ioniq’s strength. The focus is on minimizing fuel consumption, and the EPA figures show how well it does.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Hyundai Ioniq Blue at $750. This is based on driving 15,000 miles per year using national average fuel prices when calculated. This cost can fluctuate based on your location, but the price point gives you a good idea of the potential savings, especially against conventional gas vehicles.

Real-world expectations

EPA estimates provide a standard, but real-world fuel economy changes based on driving, traffic, and weather. The Ioniq Blue, however, tends to deliver numbers very close to its EPA ratings.

Careful drivers who accelerate smoothly, anticipate traffic, and use the car’s Eco mode can often match or exceed the 58 MPG combined figure. Aggressive driving or frequent short trips in cold weather can slightly reduce fuel economy. Even then, the Ioniq Blue remains efficient.

How it compares

The Ioniq Blue’s main competitor is the Toyota Prius Eco, rated at 56 MPG combined. The Prius has a better brand reputation, but the Ioniq Blue often wins on price and handling. Another competitor is the Honda Insight, which achieves 52 MPG combined. The Insight is a conventional sedan with a slightly nicer interior, but it uses more fuel. Buyers considering the Ioniq Blue are often focused on MPG, and want to determine which vehicle offers the best blend of efficiency, price, and practicality and you can check IONIQ MPG across all years.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the Ioniq Blue. Avoid sudden bursts of speed and maintain a steady pace. The electric motor provides torque at lower speeds, so use this to significantly reduce gasoline consumption. This is important in the city, where frequent acceleration and braking can hurt fuel economy.

Proper tire inflation is important for efficiency. Check your tire pressure regularly and make sure it matches what’s listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, causing the engine to work harder and use more fuel. And make sure you’re not loading the car down with things you don’t need. Extra weight reduces fuel economy.

Use the car’s Eco mode whenever possible. This mode adjusts the throttle and transmission to prioritize fuel efficiency. It may slightly reduce performance, but the impact on MPG can be noticeable, especially when cruising. Don’t be afraid to use Sport mode when needed to accelerate quickly.

Plan your routes to avoid stop-and-go traffic. Idling uses fuel without going anywhere, so routes with fewer lights and less congestion can improve your MPG. Using navigation apps to anticipate traffic jams can help you choose efficient routes.

When choosing accessories, think about the Ioniq Blue’s efficiency. Roof racks and cargo carriers can increase drag, reducing fuel economy. If you regularly carry cargo, consider a more aerodynamic cargo box or removing the rack when not in use. For all Hyundai fuel economy data, you can visit FuelEconomyHub to check all the other models.
