The 2021 Hyundai Ioniq Blue achieves 59 MPG combined, putting it in hypermiler territory. It accomplishes this through a focus on efficiency. This car isn’t for thrill-seekers or luxury buyers. It’s for drivers who want to minimize their environmental impact and maximize savings at the pump.

City and highway performance

The Ioniq Blue’s EPA ratings of 58 MPG city and 60 MPG highway show a vehicle with consistent fuel consumption across different driving environments. This is largely because of its efficient 1.6L 4-cylinder engine and a six-speed automatic transmission tuned for economy. The Ioniq Blue’s aerodynamic shape is also critical, slicing through the air with minimal resistance while navigating stop-and-go traffic or cruising on the open road. The small difference between city and highway MPG is because it’s primarily built to deliver consistent efficiency in most driving conditions.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Hyundai Ioniq Blue at a low $750. This is calculated based on driving 15,000 miles per year, using the national average fuel price at the time of calculation. For drivers covering more miles, or those facing higher local fuel costs, the savings can still be substantial compared to a conventional gasoline vehicle. This cost is a primary purchase reason for many buyers.

Real-world expectations

While the EPA estimates are a useful benchmark, real-world fuel economy can vary depending on driving habits, climate, and terrain. Aggressive acceleration, frequent hard braking, and extended idling can negatively impact fuel consumption. But even with less-than-ideal driving, Ioniq Blue owners report achieving excellent MPG figures close to the EPA’s estimates. The car’s design and tuning encourage smooth, efficient driving, making it easier to achieve high mileage. The Ioniq Blue does not require special driving habits. It will simply deliver amazing fuel efficiency without constant driver monitoring.

How it compares

The Ioniq Blue’s main rival is the Toyota Prius Eco, which achieves 56 MPG combined. While seemingly close, the 3 MPG advantage for the Ioniq Blue can add up to significant savings over the lifespan of the vehicle. Other hybrids, such as the Honda Insight (52 MPG combined) and the Hyundai Elantra Hybrid (54 MPG combined), also offer excellent fuel economy but fall short of the Ioniq Blue’s benchmark. For buyers solely focused on maximizing fuel efficiency, and who are not cross-shopping for plug-in capability, the Ioniq Blue stands out.

Tips to maximize efficiency

Gentle acceleration and braking are essential for maximizing fuel economy in the Ioniq Blue. Avoid abrupt changes in speed and anticipate traffic flow to maintain a steady pace. The Ioniq is equipped with regenerative braking, so mastering gentle deceleration will allow the system to capture more energy and recharge the battery, improving overall MPG. The IONIQ MPG across all years is impressive and consistently high, and these tips will help you get the most out of any Ioniq Hybrid IONIQ MPG across all years.

Proper tire inflation is critical for optimal fuel efficiency. Check your tire pressure regularly and maintain it at the recommended level listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, which forces the engine to work harder and consumes more fuel. A quick check every couple of weeks can make a noticeable difference.

Reduce unnecessary weight in the vehicle. Excess cargo adds to the vehicle’s overall weight and reduces fuel economy. Remove any items you don’t need to lighten the load and improve MPG. The Ioniq Blue is not intended for heavy hauling, so keep it light to maximize efficiency.

Minimize air conditioning usage whenever possible. The AC compressor puts a significant load on the engine, which can decrease fuel economy, especially in city driving. Using the vehicle’s ventilation system or opening windows at lower speeds can help reduce AC dependency and save fuel. When needed, use the Auto setting on the climate control and allow the car to moderate AC use for overall energy efficiency.
