19 MPG combined. That’s the EPA’s sticker for the 2018 Kia Sorento with all-wheel drive and the 3.3L V6. It’s a number that needs context, because while it won’t win any hypermiling awards, it represents the trade-off buyers willingly make for the Sorento’s specific blend of attributes: a useable third row, confident power, and all-weather traction at a price point that undercuts many of its rivals. This isn’t a vehicle for eco-minded minimalists; it’s for families who need space, capability, and a comfortable ride without breaking the bank. And those families understand that comes with a fuel economy compromise, even though better options exist for maximizing MPG.

City and highway performance

The EPA breaks down the Sorento’s fuel consumption further, estimating 17 MPG in the city and 23 MPG on the highway. The lower city figure reflects the inherent inefficiency of stop-and-go driving, where the engine spends more time idling and accelerating. The 23 MPG highway number is more palatable, suggesting that longer road trips won’t be quite as painful at the pump. Remember that these are just estimates, and individual driving style (heavy foot versus gentle acceleration) and prevailing conditions (wind resistance, terrain) will significantly influence the actual numbers you see on your dashboard.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2018 Kia Sorento AWD 3.3L V6 is $2,300. This figure is based on driving 15,000 miles per year and using the national average for gasoline prices at the time of calculation. When considering the Sorento, it’s critical to factor this cost into your overall budget. While the initial purchase price might be appealing, the ongoing fuel expenses can add up significantly over the lifespan of the vehicle. Buyers should check their current gas prices against government estimates for a more accurate picture. Check this page to view all Kia fuel economy data.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world MPG often varies. Owners of the 2018 Sorento AWD 3.3L frequently report figures that hover around the EPA’s combined estimate, but this depends heavily on driving style and terrain. Expect your MPG to dip significantly if you spend most of your time in stop-and-go traffic or consistently drive uphill. Conversely, steady highway cruising at moderate speeds can yield results closer to the EPA’s 23 MPG highway estimate, sometimes even exceeding it slightly. If you’re consistently falling short, evaluate your driving habits and the routes you typically take.

How it compares

The 2018 Kia Sorento exists in a competitive segment, and understanding its fuel economy in relation to rivals is important. For example, a similarly equipped Honda Pilot with all-wheel drive achieves around 22 MPG combined, which is better than the Sorento by a noticeable margin. The Toyota Highlander, a perennial favorite, clocks in around 21 MPG combined with its V6 and all-wheel drive. However, both the Pilot and Highlander typically cost more than the Sorento. Even the base-model Sorento with the less powerful, but more efficient, 2.4L engine only gets around 25 MPG combined with front wheel drive. If fuel economy is a primary concern, consider browsing the SORENTO MPG across all years, or the smaller, more fuel-efficient SUVs available on the market, though you’ll likely sacrifice some of the Sorento’s seating and towing capability.

Tips to maximize efficiency

The Sorento’s 3.3L V6 benefits from smooth, deliberate acceleration. Avoid aggressive starts and hard braking, as these actions consume disproportionate amounts of fuel. Anticipate traffic flow and maintain a consistent speed whenever possible. The Sorento’s weight and all-wheel-drive system mean that every little bit of fuel-conscious driving helps.

Regular maintenance is crucial for optimal fuel economy. Ensure your tires are properly inflated to the recommended pressure, as underinflated tires increase rolling resistance and reduce MPG. Schedule routine tune-ups, including air filter replacements, to keep the engine running efficiently. A well-maintained engine is a more efficient engine.

Minimize the use of accessories that place extra load on the engine. Air conditioning, especially on hot days, can significantly decrease fuel economy. Use it carefully, and consider opening windows when appropriate. Also, remove any unnecessary cargo from the vehicle to reduce weight, as every extra pound contributes to lower MPG.

Plan your routes strategically to avoid congested areas and unnecessary stops. Idling burns fuel without covering any distance, so minimizing idle time can make a noticeable difference. Use navigation apps and traffic updates to find the most efficient routes, even if they are slightly longer in distance. Consider using public transport some days.
