24 MPG combined isn’t going to set any records, but it’s a perfectly reasonable number for the 2024 Lexus NX 350 AWD. More importantly, it’s a fuel economy figure that NX 350 buyers are willing to accept, because what they are *really* buying is compact luxury, a comfortable ride, and the peace of mind that comes with the Lexus badge. This isn’t a vehicle aimed at hypermilers; it’s designed to be a stylish and reliable daily driver with a touch of premium flair, and for that mission, its fuel consumption is acceptable.

City and highway performance

The 2024 NX 350, equipped with its 2.4L turbocharged four-cylinder engine and eight-speed automatic transmission, delivers 21 MPG in the city and 28 MPG on the highway, according to EPA estimates. The city figure reflects the realities of stop-and-go traffic, where the engine spends more time idling and accelerating.

The highway MPG demonstrates the engine’s efficiency when cruising at consistent speeds. Owners who spend the majority of their time on the open road will likely see closer to that 28 MPG figure, especially if they employ conservative driving habits. Remember that these are EPA estimates, and your actual mileage will fluctuate based on driving style, road conditions, and even tire pressure.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Lexus NX 350 AWD at $2,400. This figure is based on driving 15,000 miles per year and using national average fuel prices.

This is a significant expense to consider over the vehicle’s lifespan, so it’s wise to factor it into your overall budget. National average fuel prices are estimates, of course, and may be drastically different than what you pay in your own geographic location. Still, it serves as a good relative reference in a world where fuel costs are often rapidly changing.

Real-world expectations

While the EPA provides standardized testing, real-world fuel economy can vary. Aggressive driving, frequent short trips, and carrying heavy loads will decrease your MPG. Conversely, gentle acceleration, consistent speeds, and proper vehicle maintenance can improve it.

Many NX 350 owners have reported fuel economy figures that are close to the EPA estimates, but some drivers who prioritize performance over efficiency may see slightly lower numbers. If you’re concerned about maximizing your fuel economy, it’s advisable to monitor your driving habits and adjust accordingly. You can also compare NX MPG across all years to look at long-term owner trends.

How it compares

In the competitive compact luxury SUV segment, the NX 350’s fuel economy is right in the mix. For example, the Acura RDX, a popular alternative, achieves a slightly lower 23 MPG combined with its standard AWD. A BMW X3 xDrive30i, another strong contender, is rated at 24 MPG combined like the NX. The Mercedes-Benz GLC 300 4MATIC offers a closely comparable 26 MPG combined making it a particularly efficient choice overall.

These differences, while seemingly small on paper, can add up over the years. Potential buyers should consider more than just MPG figures. All of these vehicles offer varying degrees of luxury, performance, and features. The Lexus badge typically commands a degree of perceived reliability, and for some buyers, that is worth a slight sacrifice in fuel economy.

Tips to maximize efficiency

The NX 350’s turbocharged engine responds well to smooth and deliberate throttle inputs. Avoid aggressive acceleration and hard braking, as these actions consume more fuel. Anticipate traffic flow and maintain a steady speed whenever possible.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended levels, which can be found on a sticker inside the driver’s side door jamb or in your owner’s manual.

Reduce unnecessary weight in your vehicle. Extra cargo adds to the vehicle’s overall weight, which forces the engine to work harder. Remove any items you don’t need, especially heavy objects. Also, resist loading cargo onto the roof if you can store it inside, as this increases aerodynamic drag.

Regular maintenance is critical for optimal fuel economy. A properly maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug replacements. Consider using Top Tier fuel for the best engine cleanliness and emissions profile.

Use cruise control on long highway drives. Cruise control helps maintain a consistent speed, which can improve fuel efficiency. However, avoid using cruise control in hilly terrain, as the vehicle may downshift frequently, negating some of the fuel-saving benefits.
