The 2021 Lexus NX 300 AWD gets 24 MPG combined. This doesn’t make it a fuel-sipping SUV, but it does offer style and comfort in a compact package. It prioritizes luxury and predictable performance over maximum fuel conservation. This number shows the trade-off consumers accept when choosing a vehicle known for its comfortable ride, attractive design, and standard all-wheel drive, rather than class-leading efficiency. Buyers often compromise slightly on fuel economy for the NX’s reputation for reliability and the appeal of the Lexus brand.

City and highway performance

The EPA estimates the NX 300 AWD will achieve 22 MPG in the city and 28 MPG on the highway. The city figure is particularly relevant. Many NX 300 owners use their vehicles for daily commutes and errands in urban environments, where stop-and-go traffic reduces fuel efficiency. The highway number is better, suggesting that longer trips will yield more favorable results. These figures come from the 2.0L turbocharged four-cylinder engine paired with a traditional six-speed automatic transmission, a setup that prioritizes smoothness over the fuel-saving technologies found in some competitors.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2021 Lexus NX 300 AWD is $2,400. This is based on driving 15,000 miles per year and using national average fuel prices. Individual costs will vary depending on driving habits, local fuel prices, and the type of fuel used. While this provides a standardized comparison point, keep in mind that aggressive driving or consistently using premium fuel (though not required) could increase your actual spending.

Real-world expectations

EPA estimates provide a useful baseline, but real-world fuel economy often differs. NX 300 owners frequently report MPG numbers that fluctuate within a few MPG of the official figures. Factors like driving style, terrain, and weather conditions all influence fuel consumption. Aggressive acceleration and frequent hard braking will reduce efficiency, as will driving in hilly areas or severe weather. Consistent highway driving at steady speeds will likely yield results closer to the 28 MPG highway estimate. Owners should track their own fuel economy to understand their personal averages.

How it compares

The NX 300 AWD’s fuel economy positions it in the middle of the compact luxury SUV segment. The Acura RDX, another popular choice, gets an EPA-estimated 23 MPG combined. The BMW X3 sDrive30i (rear-wheel drive) achieves a slightly better 25 MPG combined, but opting for xDrive (all-wheel drive) brings it closer to the NX. The Audi Q5, rated at 25 MPG combined, offers a marginal improvement, but the differences are often negligible in real-world driving. Buyers prioritize the Lexus’ reputation for reliability and its comfortable interior. For customers wanting class leading efficiency, the NX 300h hybrid sees economy figures in the high 30’s.

Tips to maximize efficiency

Maintain consistent speeds whenever possible. The NX 300 AWD’s turbocharged engine is responsive, but frequent bursts of acceleration consume more fuel. Use cruise control on the highway to maintain a steady pace and optimize fuel economy.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel efficiency. Check tire pressures regularly and inflate them to the recommended levels listed on the driver’s side door jamb.

Avoid unnecessary cargo. Extra weight reduces fuel economy. Remove any items you don’t need from the vehicle, especially heavy objects in the trunk or cargo area. The NX is known to be on the smaller side for cargo volume compared to competitors, so keeping it free from unnecessary weight ensures optimal mileage.

Consider using the “ECO” driving mode. This mode adjusts throttle response and other vehicle settings to prioritize fuel efficiency. Activating ECO mode limits the responsiveness from the 2.0L turbo, but for daily driving and on the highway, it will increase your vehicle’s economy.

Schedule regular maintenance. A well-maintained engine runs more efficiently. Follow the recommended maintenance schedule for your NX 300 AWD, including oil changes, air filter replacements, and spark plug inspections.
