24 MPG combined is an adequate figure for the 2021 Hyundai Santa Fe AWD 2.5L 4-cyl, but understanding that “adequate” is precisely the point is critical. This isn’t a hybrid; it’s a comfortable, family-oriented car with optional all-wheel drive, built for dependability rather than hyper-efficiency. It gets the job done without using too much fuel, and that’s exactly what its target buyer expects.

City and highway performance

The Santa Fe AWD 2.5L delivers 21 MPG in the city and 28 MPG on the highway. These numbers reflect the engine’s tuning for mid-range torque and responsiveness, prioritizing everyday drivability over fuel conservation. The 8-speed automatic transmission (AM-S8) also plays an important role in these figures. Its relatively wide ratio spread allows for quick acceleration around town and relaxed cruising on the open road. Around town, the engine delivers decent power in normal driving conditions but lacks the grunt you would get with a larger engine. At highway speeds, the aerodynamics of the vehicle limit fuel efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2021 Hyundai Santa Fe AWD 2.5L at $1,800. This calculation is based on driving 15,000 miles per year, with 55% of those miles driven in city conditions, and 45% in highway conditions, and using national average fuel prices at the time of calculation. The actual cost will vary based on individual driving habits, local fuel prices, and the grade of fuel used. If you drive predominantly in the city, or are heavy with the accelerator pedal, expect to exceed this $1,800 figure.

Consider that the EPA fuel cost is calculated assuming the vehicle uses regular gasoline (87 octane), which is ideal for this engine.

Real-world expectations

Real-world fuel economy for the Santa Fe typically aligns fairly closely with the EPA estimates, especially with mindful driving habits. However, factors such as cold weather, frequent short trips, and aggressive acceleration can quickly reduce those numbers. Owners who spend a significant amount of time in stop-and-go traffic can expect figures closer to the 21 MPG city rating, while those who primarily use it for highway commuting might see results approaching or even slightly exceeding the 28 MPG highway estimate.

The all-wheel-drive system itself impacts fuel economy to a small degree, generally seeing a 1-2 MPG decrease over the front-wheel-drive version, depending on the specific driving conditions (which do not include off-roading for the vast majority of Santa Fe owners).

How it compares

Compared to its competitors, the 2021 Hyundai Santa Fe’s fuel economy is competitive within its segment. The Toyota RAV4 AWD, for example, achieves a slightly better 30 MPG combined in its non-hybrid form, while the Honda CR-V AWD posts around 29 MPG combined. The Nissan Rogue AWD is closer to the Santa Fe claiming 28 MPG combined. However, those vehicles often require compromises in features or interior space.

The Santa Fe offers a comfortable ride quality and a generous list of standard equipment, making it a good option for buyers who prioritize those aspects over the absolute best fuel efficiency. For buyers seeking even better MPG in this segment, a hybrid trim such as the Santa Fe Hybrid Blue nets 34 MPG combined while offering all-wheel drive. Stepping up to the hybrid means paying more at the time of purchase.

Tips to maximize efficiency

One of the simplest ways to improve MPG in the 2.5L Santa Fe is to ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended PSI listed on the door jamb sticker or in your owner’s manual.

Avoid aggressive acceleration and braking. The 2.5L engine responds well to smooth, gradual throttle inputs. Anticipate traffic flow and maintain a steady speed whenever possible to minimize unnecessary fuel consumption. Using cruise control on the highway can contribute to more consistent fuel economy.

Reduce unnecessary weight. Hauling around extra cargo in the Santa Fe adds to the vehicle’s overall weight, which negatively impacts fuel efficiency. Remove any items you don’t need on a regular basis; this is especially important if you routinely carry heavy items that rarely get used.

Consider using the “Smart” driving mode, if equipped. This mode automatically adjusts engine and transmission settings to optimize fuel efficiency based on driving conditions. While not as aggressive as “Eco” mode, it provides a balance of performance and fuel economy for everyday driving.

Finally, keep up with regular maintenance. A well-maintained engine runs more efficiently. This includes timely oil changes, air filter replacements, and spark plug replacements. Neglecting these maintenance tasks can lead to decreased performance and reduced fuel economy over time.
