20 MPG combined isn’t going to win any fuel-sipping awards, but it’s the figure the 2018 Kia Sorento FWD 3.3L V6 delivers, and it’s a number that many drivers are willing to accept for the capability and space this mid-size SUV offers. This configuration of the Sorento is for families who need three rows of seating and a reliable V6 engine for road trips and daily errands, but aren’t particularly concerned with maximizing fuel efficiency above all else. They prioritize passenger comfort, cargo capacity, and a smooth driving experience, and they’re willing to trade a few MPGs to get it.

City and highway performance

The EPA estimates the 2018 Kia Sorento FWD 3.3L V6 at 18 MPG in the city and 25 MPG on the highway. The city figure reflects the fuel consumption during stop-and-go traffic, typical short trips, and idling at traffic lights. The highway figure, on the other hand, demonstrates how efficiently the Sorento cruises at sustained speeds, making it a reasonable choice for long-distance travel to visit Grandma. This contrast highlights the Sorento’s strength; while not stellar in urban environments, it holds its own on extended highway journeys. These numbers reflect the Sorento when it’s working hardest, and when it’s allowed to loaf.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Kia Sorento FWD 3.3L V6 to be $2,200. This figure is calculated based on driving 15,000 miles per year, using a blend of city and highway driving, and assuming national average fuel prices. It’s important to remember that this is just an estimate, and your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and local gasoline prices. If you consistently encounter heavy traffic and aggressive driving, expect to exceed this amount.

Conversely, if you baby the throttle and live where fuel prices are low, you could come in below $2,200. This estimate provides a valuable benchmark for comparing Sorento fuel costs with other SUVs.

Real-world expectations

EPA estimates provide a consistent baseline, but real-world fuel economy often differs. SORENTO MPG across all years depends heavily on factors like driving style, road conditions, and even tire pressure. Aggressive acceleration, frequent hard braking, and neglecting routine maintenance can all negatively affect fuel economy. Similarly, driving in hilly terrain or consistently carrying heavy loads will increase fuel consumption.

Consult online forums and owner reviews to gain a more nuanced understanding of what actual Sorento drivers are experiencing on the road. The experiences of drivers who frequently use the Sorento’s full seating capacity and towing capabilities will be especially valuable.

How it compares

Among mid-size SUVs with V6 engines and three-row seating, the 2018 Kia Sorento’s fuel economy is generally competitive. For example, the 2018 Honda Pilot FWD offers a slightly better EPA-estimated combined fuel economy of 22 MPG with its 3.5L V6. The Toyota Highlander with its 3.5L V6 also achieves around 22 MPG combined.

Meanwhile, the Nissan Pathfinder, another popular choice, lands in roughly the same ballpark as the Sorento. The all-wheel-drive versions of these competitors typically see a slight decrease in fuel economy compared to their front-wheel-drive counterparts. For Sorento buyers, this comparison highlights the trade-off between performance and fuel efficiency; while there are marginally more efficient options, the Sorento’s combination of value, space, and V6 power is persuasive.

Tips to maximize efficiency

Gentle acceleration is key. Avoid flooring the accelerator pedal, especially from a standstill. The Sorento’s V6 engine is responsive, but it consumes considerably more fuel under heavy loads. Smooth, gradual acceleration will help you minimize fuel consumption and make the most of each gallon.

Maintain optimal tire pressure. Underinflated tires increase rolling resistance, which forces the engine to work harder and reduces fuel economy. Check your tire pressure regularly, typically every few weeks, and inflate them to the recommended pressure listed on the sticker inside the driver’s side door jamb. A small investment in a tire pressure gauge can save you money at the pump.

Reduce unnecessary weight. Carrying excess weight in the Sorento’s cargo area or on the roof rack will decrease fuel economy. Remove any items that you don’t need on a regular basis, such as sports equipment, tools, or extra supplies. This is especially important during long road trips, where the cumulative effect of added weight can be significant.

Use cruise control on the highway. Maintaining a consistent speed on the highway reduces unnecessary acceleration and deceleration, which can improve fuel economy. Use cruise control whenever possible, especially on long, level stretches of road. However, be mindful of traffic conditions and disengage cruise control when necessary for safety.

Avoid idling for extended periods. When stopped for more than a minute or two, turn off the engine to save fuel. Modern engines restart quickly and easily, so there’s no need to let the engine idle unnecessarily. This is particularly true in stop-and-go traffic, where idling can consume a significant amount of fuel over time.
