24 MPG combined won’t win any awards in the compact luxury SUV segment, but the 2021 Lexus NX 300 AWD F Sport isn’t chasing efficiency accolades. This is a stylish, comfortable, and dependable choice for buyers who prioritize reliability and resale value over advanced, fuel-sipping technology. This demographic values the NX’s reputation and knows they won’t be stranded on the side of the road. For them, the fuel cost is simply part of the ownership equation. They want the sporty look of the F Sport, and they are willing to accept a fuel economy that is just “OK” in exchange for the Lexus badge and design.

City and highway performance

The EPA estimates for the NX 300 F Sport are 22 MPG in the city and 27 MPG on the highway. The city fuel economy reflects the reality of stop-and-go traffic where the 2.0L turbocharged four-cylinder has to work harder to get the NX moving. Once up to speed on the highway, the engine settles into a more efficient cruising mode. While 27 MPG is respectable, it’s not class-leading, and some buyers might find it a little disappointing for a vehicle of this size. Still, with the responsive and well-tuned six-speed automatic, the NX is reasonably fun to drive, and the engine’s power delivery feels appropriate for its mission.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2021 Lexus NX 300 AWD F Sport to be $2,400. This figure is based on driving 15,000 miles per year and using the national average fuel prices at the time of calculation. Keep in mind that this is an estimate, and your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and how often you drive. Those who drive more than 15,000 miles per year will, of course, spend more, and with premium fuel recommended, NX owners may see even higher fuel costs.

Real-world expectations

While the EPA estimates provide a good baseline, real-world fuel economy can vary. Many drivers report slightly lower numbers than the official ratings, especially if they frequently drive in demanding conditions. Aggressive acceleration and constant braking hurt MPG. However, consistently smooth driving and using the vehicle’s Eco mode may help achieve numbers closer to, or even slightly above, the EPA estimates. The NX’s relatively small fuel tank also means more frequent fillups for those who complete long commutes.

How it compares

Compared to its competitors, the NX 300 F Sport’s fuel economy lands somewhere in the middle of the pack. The Acura RDX, for example, with its turbocharged 2.0L engine, delivers around 22 MPG combined. The BMW X3 sDrive30i, a rear-wheel drive model, achieves around 25 MPG combined, offering a slight advantage. The Volvo XC60 T5 FWD manages a similar 26 MPG combined. Buyers prioritizing fuel economy above all else may consider alternatives like the hybrid versions offered by several brands. For all Lexus fuel economy data, you can visit our research pages.

The NX owner isn’t chasing every single MPG, but it’s smart to understand the landscape of fuel-efficient luxury SUVs.

Tips to maximize efficiency

While this is not a hybrid, there are several ways to make the most of every gallon in your NX 300 F Sport. Avoid aggressive acceleration and hard braking, as these habits consume significantly more fuel. Anticipate traffic flow and maintain a steady speed whenever possible. The less time your engine spends accelerating, the further your tank will go.

Ensure your tires are properly inflated according to the manufacturer’s specifications. Underinflated tires create more rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly, especially during changes in temperature, as that affects tire pressure.

Reduce unnecessary weight in the vehicle, as extra cargo impacts fuel economy. Remove items you don’t need from the trunk and back seats. Every extra pound contributes to fuel consumption, especially in city driving.

Use the vehicle’s Eco mode. This mode adjusts the throttle response and transmission settings to prioritize fuel efficiency over performance. While it may slightly reduce acceleration, it can make a noticeable difference in fuel consumption, especially on longer trips.

Keep up with regular maintenance, including oil changes and air filter replacements. A properly maintained engine runs more efficiently. Fresh oil reduces friction, and a clean air filter ensures optimal airflow, both of which contribute to better fuel economy.
