89 MPGe combined classifies the 2025 Kia EV9 Long Range RWD as an efficient large electric SUV, and it makes a statement. This is not a niche compact or a glorified golf cart; this is a three-row family hauler, a proper road-trip machine, designed to transport significant weight and offer substantial comfort. Achieving nearly 90 MPGe in a vehicle of this size, with its commanding presence and impressive interior volume, shows the rapid advancements in EV technology and Kia’s commitment to making electrification work for everyone, not just early adopters. It’s a remarkable figure for a vehicle that’s fundamentally changing expectations of what a family SUV can be.

City and highway performance

Looking at the EPA figures, the 2025 EV9 Long Range RWD registers 100 MPGe in the city and 78 MPGe on the highway. These numbers, particularly the 100 MPGe city rating, highlight the strengths of electric powertrains in urban environments. Stop-and-go traffic, often a problem for internal combustion engines, becomes a regenerative opportunity for the EV9. Each deceleration pours energy back into the battery, making city driving remarkably efficient. This is ideal for the typical suburban family, navigating school drop-offs, grocery runs, and daily commutes. Even the 78 MPGe highway figure is strong for a vehicle of this aerodynamic profile and weight. While the sustained high speeds of highway driving naturally reduce the regenerative braking opportunities, the EV9’s efficient electric motor and large battery capacity ensure respectable long-distance efficiency. It’s a powertrain well-suited for those who split their driving time between congested urban areas and open stretches of road, and it truly shines where combustion vehicles typically falter most.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Kia EV9 Long Range RWD at a remarkably low $850. This figure is calculated based on 15,000 miles of driving per year, split evenly between city and highway conditions, and using national average electricity prices. This shows the financial advantages of electric vehicle ownership, especially when compared to similarly sized gasoline-powered SUVs. For families transitioning from a conventional three-row SUV, this $850 annual cost represents a significant saving, freeing up substantial budget that would otherwise be spent at the pump. This is the real-world impact of choosing an efficient EV. All Kia fuel economy data benefit from this shift, but in a large vehicle like the EV9, the savings are even more pronounced.

Real-world expectations

The 2025 Kia EV9 Long Range RWD’s MPGe figures are strong, but real-world expectations need to account for several factors. Drivers who consistently push hard, live in extremely cold climates, or frequently carry a full load of passengers and cargo will see figures slightly below the EPA estimates. Conversely, a driver with a light foot, who pre-conditions the cabin while still plugged in, and mostly drives in moderate temperatures, may even exceed the ratings. The EV9’s mission as a family vehicle means it will often be subjected to diverse conditions. Regular use of rapid chargers, which are less efficient than Level 2 home charging, will also marginally impact actual costs and overall efficiency. However, the fundamental efficiency of the platform ensures that even under less-than-ideal circumstances, the EV9 remains a very inexpensive vehicle to ‘fuel.’ The buyer for this specific EV9 trim is someone prioritizing range and efficiency over outright speed, willing to trade the all-wheel-drive traction for maximum miles per charge and the lowest operating costs. They are often coming from a minivan or a large gasoline SUV, keenly aware of recurring fuel expenses and eager to eliminate them. They appreciate the quiet and practical benefits of electric power, and they’re ready for a change from the gas pump.

How it compares

Comparing the 2025 Kia EV9 Long Range RWD with its 89 MPGe combined rating reveals its competitive edge. Take for instance, the all-electric RWD variant of the Tesla Model X, which boasts a combined 102 MPGe. While slightly more efficient on paper, the Model X occupies a different price point and offers a distinct, sportier driving character. A more direct competitor might be the Rivian R1S Dual-Motor Standard battery, which comes in closer to 69 MPGe combined, though its focus is more on off-road capability and raw power. Looking at internal combustion engine rivals, the disparity is stark. A gasoline-powered three-row SUV like the Kia Telluride AWD delivers around 21 MPG combined, making the EV9 Long Range RWD’s operating costs astronomically lower. Even the Lexus TX 500h F Sport Performance hybrid, a relatively efficient option, manages only 27 MPG combined. The buyer choosing the EV9 Long Range RWD is specifically seeking that blend of family-friendly size, impressive range on a single charge, and superior efficiency, often at a more accessible price point than some premium electric rivals. They prioritize the long-term running costs and environmental benefits without sacrificing practicality. For a detailed look at the model’s range, consult EV9 MPG across all years.

Tips to maximize efficiency

Pre-conditioning the cabin while the vehicle is still plugged into a charger significantly reduces energy drain from the battery once you’re on the road. This warms or cools the interior using grid power, not battery power, making your initial driving more efficient.

Maintain consistent, smooth acceleration and braking. Abrupt changes in speed force the electric motor to work harder and reduce the effectiveness of regenerative braking. Think of it as a smooth, flowing motion rather than stop-and-go.

Use the EV9’s various drive modes. Eco mode is designed to optimize efficiency by moderating throttle response and climate control, perfect for maximizing range on daily commutes.

Keep your tires properly inflated to the recommended pressure. Under-inflated tires increase rolling resistance, forcing the motor to consume more energy to maintain speed, directly impacting your MPGe.

Plan your routes to include opportunities for Level 2 charging, especially overnight. While DC fast charging is convenient, Level 2 is more efficient in how it replenishes the battery, reducing overall energy loss during the charging process.
