The 2024 Lexus NX 350 AWD F Sport, with its 2.4L turbocharged 4-cylinder engine, achieves 24 MPG combined. This isn’t stellar fuel economy, but it’s a reasonable trade-off for buyers who prioritize a sporty driving experience and the security of all-wheel drive in a compact luxury SUV. The F Sport trim targets those who want a sharper look and slightly more engaging performance than the standard NX. These drivers are often willing to accept a small fuel economy penalty for that extra dose of style and responsiveness.

City and highway performance

The EPA estimates the 2024 Lexus NX 350 AWD F Sport gets 21 MPG in the city and 28 MPG on the highway. The city figure reflects the demands of stop-and-go traffic, where the NX 350’s turbocharger can work harder, reducing efficiency. The highway figure is more respectable, demonstrating the engine’s ability to cruise efficiently at steady speeds. Aggressive driving habits will significantly impact these numbers, especially in urban environments.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,400 for the 2024 Lexus NX 350 AWD F Sport. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Remember that your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and local gas prices. It’s a helpful starting point for budgeting, but personalize it for a more accurate forecast.

Real-world expectations

EPA estimates provide a standardized benchmark, but real-world fuel economy often deviates. Expect to see figures slightly below the EPA estimates, especially with frequent use of the Sport drive mode. Short trips, cold weather, and hilly terrain can further reduce fuel efficiency. Drivers who prioritize fuel economy will likely achieve numbers closer to the EPA estimates by adopting a smoother driving style and minimizing aggressive acceleration.

How it compares

The 2024 Lexus NX 350 AWD F Sport’s fuel economy sits in the middle ground within its competitive set. The Acura RDX SH-AWD, for example, is rated at 21 MPG city, 27 MPG highway, and 23 MPG combined, which is slightly lower than the NX.
The BMW X3 xDrive30i achieves 23 MPG city, 29 MPG highway, and 25 MPG combined, giving it an advantage. The NX hybrid models, such as the NX 350h, offer significantly better fuel economy, reaching 41 MPG city and 37 MPG highway, but at a higher upfront cost. These comparisons matter to NX 350 buyers because they often cross-shop these specific models, balancing performance aspirations with budget realities. The NX MPG across all years is available to see how efficiency has evolved.

Tips to maximize efficiency

Use the NX 350’s Eco drive mode in everyday driving. This mode adjusts throttle response and transmission mapping to prioritize fuel efficiency. It might make the car feel slightly less responsive, but over the long run, it can have a tangible impact.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels on the tire placard.

Avoid unnecessary idling. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and idling wastes fuel without providing any benefit.

Lighten the load. Carrying unnecessary weight in your vehicle decreases fuel efficiency. Remove any items you don’t need from the trunk or cargo area to minimize the load on the engine.

Combine trips and plan your routes efficiently. Avoid making multiple short trips when possible, as the engine consumes more fuel when it’s cold. Consolidate errands into a single trip and plan your route to minimize stop-and-go traffic.
