88 MPG combined is a major achievement for a family SUV. The 2024 Kia EV9 Standard Range RWD gets this figure as an electric vehicle, not a hybrid. This is about rethinking family transportation, with cost savings, lower fuel costs, and near-silent operation all in a spacious three-row package. Buyers who are okay with the Standard Range RWD will likely be those needing a practical family vehicle for suburban or urban environments who don’t need maximum range and want to minimize operating costs.

City and highway performance

The city rating of 99 MPG shows the EV9’s strength in stop-and-go traffic. Regenerative braking recovers energy that would otherwise be lost. Traditional gasoline SUVs often see a significant drop in MPG in city environments, but the EV9 shines. The city MPG result illustrates how the EV9 can serve as a commuter or school vehicle without large fuel bills. The highway rating of 77 MPG is still impressive, showcasing the EV9’s efficiency at higher speeds. Aerodynamic drag plays a larger role at highway speeds, but the electric powertrain still delivers impressive results. This makes medium-distance family road trips possible, especially with planned charging stops.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Kia EV9 Standard Range RWD at $850. This is based on 15,000 miles per year, with a mix of city and highway driving, using national average electricity prices. The EPA uses its MPG figures to estimate total electricity usage, and then multiplies that consumption by the average cost per kilowatt-hour in the United States. This is a strong selling point for EV9 buyers, especially those trading in a gasoline-powered SUV that might cost two or three times as much to fuel each year. It’s a reminder of the potential long-term savings from electric vehicle ownership.

Real-world expectations

EPA figures are a standardized benchmark, but real-world MPG will vary. Driving style, weather, and accessories like air conditioning can all impact energy consumption. Aggressive acceleration and hard braking will deplete the battery faster than gentle driving. Extreme temperatures can affect battery performance, reducing range in both hot and cold conditions. Charging habits also matter. Charging to 100% or frequently depleting the battery to near-zero can degrade battery health over time, potentially impacting efficiency.

Drivers who monitor their driving habits and charging patterns are more likely to achieve results similar to the EPA estimates. The EV9’s onboard systems provide tools to help drivers do this.

How it compares

The EV9 is in a unique segment. Few other electric SUVs offer three rows of seating. The Tesla Model X offers more range and performance, but at a higher price. The Model X Long Range achieves an EPA-estimated 102 MPGe combined. Buyers prioritizing affordability and space will strongly consider the EV9 Standard Range. The EV9’s fuel economy advantage over gasoline-powered three-row SUVs is clear. The Toyota Highlander Hybrid achieves 36 MPG combined, and the EV9 more than doubles that. Even larger SUVs like the Chevrolet Tahoe, at around 17 MPG combined, are far behind. This underscores the EV9’s potential to reduce running costs for families who need seating for seven or eight. For a broader look at all Kia fuel economy data, you’ll find similar advantages over comparable gas-powered models across much of their lineup. And for more information on EV9 MPG across all years, you can see how fuel efficicny has evolved over time.

Tips to maximize efficiency

Use the EV9’s regenerative braking system, especially when anticipating stops, to recapture energy and extend range.

Precondition the battery before driving, especially in cold weather. Many EVs, including the EV9, allow you to preheat the battery while plugged in, which can significantly improve range.

Keep your tires properly inflated to the pressure listed on the door jamb sticker. Underinflated tires increase rolling resistance, reducing efficiency.

Minimize unnecessary weight by removing extra cargo to improve fuel economy. Remove roof racks or cargo carriers when not in use, as they can increase aerodynamic drag.

Plan routes to minimize stop-and-go traffic and avoid hills. Smooth, consistent driving at moderate speeds is the most efficient way to operate an electric vehicle like the EV9.
