22 MPG combined isn’t going to win any fuel economy awards, but it’s a justifiable figure for the 2023 Kia Carnival. This isn’t a sleek crossover trying to be practical; it’s a minivan, designed for hauling people and their belongings in comfort. Carnival drivers prioritize space, convenience, and family-friendly features over efficiency. For that purpose, the 3.5L V6 delivers acceptable mileage and smooth, responsive power.

City and highway performance

The EPA estimates the Carnival gets 19 MPG in the city and 26 MPG on the highway. The city figure reflects stop-and-go traffic and the inefficiencies of a larger vehicle in cities. The highway number is more interesting. Minivans like the Carnival often accumulate highway miles on family road trips, and 26 MPG allows reasonably long stretches between fill-ups. The eight-speed automatic transmission helps keep the engine in its best range during long cruises.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,000 for the 2023 Kia Carnival. This is based on driving 15,000 miles per year and using national average fuel prices. The actual amount will vary depending on individual driving habits and local fuel costs, but $2,000 is a benchmark for budgeting. If you drive significantly more or less than 15,000 miles, adjust the calculation accordingly, using current gas prices in your area. Remember to factor in potential fuel price changes throughout the year.

Real-world expectations

While the EPA provides standardized testing, real-world fuel economy can be different. Aggressive driving, heavy loads, and frequent short trips will negatively impact fuel efficiency. However, gentle acceleration, consistent highway speeds, and proper vehicle maintenance can help you achieve numbers closer to the EPA estimates, or even slightly better.

The Carnival’s trip computer monitors your MPG and helps you adjust your driving habits to improve fuel economy. Observe your average MPG over time to get a realistic sense of what to expect in typical driving conditions. You can review all Kia fuel economy data on our site.

How it compares

The Honda Odyssey, a minivan benchmark, achieves a similar EPA rating of 19 MPG city, 28 MPG highway, and 22 MPG combined. The Chrysler Pacifica, in its gasoline-only configuration, mirrors the Carnival’s combined figure at 22 MPG but is slightly behind on the highway at 25 MPG. The Toyota Sienna, available exclusively as a hybrid, outperforms its competitors with 36 MPG combined.

The Sienna’s hybrid powertrain is more expensive and provides a different driving experience. For those prioritizing fuel savings, the Sienna is the better choice. But if smooth power and a traditional driving experience are important, the Carnival offers an alternative. Before deciding, you should check the CARNIVAL MPG across all years to see if newer or older models will best fit your needs.

Tips to maximize efficiency

Avoid aggressive acceleration. The Carnival’s V6 engine is responsive, but using the accelerator heavily will quickly deplete your fuel tank. Instead, aim for smooth and gradual acceleration to minimize fuel consumption. Anticipate traffic flow and a maintain a steady speed whenever possible.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the sticker inside the driver’s side doorjamb.

Lighten the load. Carrying unnecessary weight in your Carnival will decrease fuel efficiency. Remove any items you don’t need, such as sports equipment, tools, or extra luggage that isn’t essential.

Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long trips. However, avoid using cruise control in hilly terrain, as the constant adjustments can reduce efficiency. The smart cruise control can also help with safety.

Use the Carnival’s Eco mode, if equipped. This mode adjusts the engine and transmission to prioritize fuel efficiency. While it might slightly reduce performance, it can make a difference in your MPG, especially during city driving.
