The 2018 Hyundai Sonata 2.4L gets 28 MPG combined, a number that shows it is a competent and sensible mid-size sedan. This number isn’t the best in its class, nor is it disappointing, but it sits comfortably in the middle. This Sonata appeals to practical buyers who want affordability, reliability, and space over sporty handling or advanced technology. They’re looking for a dependable family car for daily commutes and weekend errands, and the 2.4L engine’s fuel economy is acceptable for that, even if it isn’t the main reason to buy it.

City and highway performance

The EPA estimates 25 MPG in the city and 35 MPG on the highway for the 2018 Hyundai Sonata 2.4L. The city figure is respectable, acknowledging the stop-and-go nature of urban driving. The 35 MPG highway rating is impressive, suggesting a comfortable and relatively efficient experience on longer road trips. These numbers come from the 2.4L four-cylinder engine paired with a smooth-shifting six-speed automatic transmission. The powertrain isn’t particularly advanced, but it’s well-proven and tuned for efficiency without sacrificing enough power for everyday driving. Drivers will find the highway MPG helpful for longer commutes or family travel.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Hyundai Sonata 2.4L at $1,550. This is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that this is only an estimate; your actual fuel costs depend on your driving habits, local fuel prices, and the amount of highway versus city driving you do. The $1,550 provides a standardized benchmark for comparing the Sonata to other vehicles and lets prospective buyers factor fuel costs into their budget.

Real-world expectations

While the EPA estimates offer a baseline, real-world fuel economy often differs. The 2018 Hyundai Sonata 2.4L typically delivers numbers close to the EPA estimates. Many owners report achieving the stated 35 MPG on the highway during longer trips, and some exceed it with careful driving. Aggressive acceleration, frequent stop-and-go traffic, and cold weather can all negatively impact fuel economy. Overall, owners of this Sonata can expect reasonably accurate fuel economy, but should always consider factors impacting MPG.

How it compares

The 2018 Hyundai Sonata 2.4L’s fuel economy is competitive in the mid-size sedan segment, although hybrid models offer superior fuel savings. For example, the Honda Accord with its base 1.5-liter turbo engine offers a significantly higher 30 MPG combined. The Toyota Camry with its base 2.5-liter engine achieves around 32 MPG combined. These MPG differences may matter to buyers who want good fuel efficiency above all else.

The Sonata often offers good value, balancing fuel economy with features and price. Buyers looking for the best MPG should consider the Hyundai Sonata Hybrid, which delivers significantly better mileage.

Tips to maximize efficiency

Gentle acceleration is important with the 2.4L engine. Avoid aggressive starts and keep a steady speed to minimize fuel use. The six-speed automatic is programmed for efficiency, but rapid changes in throttle position will force it to downshift and burn more fuel. Smooth inputs will result in better MPG, especially in city driving.

Proper tire inflation leads to measurable fuel savings. Check your tire pressure regularly and keep the recommended levels listed on the driver’s side doorjamb. Underinflated tires create more rolling resistance, which forces the engine to work harder and burn more fuel. A tire pressure gauge can pay for itself.

Remove extra weight from your vehicle. Hauling extra cargo in the trunk adds weight, which decreases fuel economy like underinflated tires. Remove items you don’t regularly need to lighten the load and improve MPG. Every little bit helps.

Use cruise control on the highway. Cruise control helps keep a consistent speed, minimizing changes in fuel use. This works best on flat stretches of highway. Turn off cruise control when driving in hilly terrain or during heavy traffic.

Regular maintenance ensures good performance. Follow the maintenance schedule in your owner’s manual. Changing the engine oil, air filter, and spark plugs at the proper intervals helps keep the engine running efficiently. A properly maintained engine burns fuel more cleanly and delivers better MPG.
