24 MPG combined isn’t going to win any awards, but for the 2020 Lexus NX 300 AWD F Sport, it’s a compromise many buyers readily accept. These are often professionals or small families drawn to the NX’s sharp styling, comfortable interior, and the Lexus reputation for reliability. Fuel efficiency, while considered, often takes a backseat to these other priorities.

City and highway performance

The EPA estimates the NX 300 AWD F Sport at 22 MPG in the city and 27 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, where the turbocharged 2.0L engine works harder, and the six-speed automatic cycles through gears more frequently. The highway number is more favorable, as the engine settles into a more efficient cruising speed. However, aggressive use of the turbocharger for passing or maintaining speed on hilly terrain will quickly bring that figure down.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2020 Lexus NX 300 AWD F Sport is approximately $2,400. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Keep in mind that your actual fuel costs may vary depending on your driving habits, the type of fuel you use (premium is recommended), and local gas prices.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy can differ significantly. Drivers with a heavy foot or those who spend most of their time in congested city traffic can expect to see numbers closer to, or even slightly below, the 22 MPG city rating. Conversely, drivers who prioritize fuel efficiency and spend the majority of their time on the highway could potentially achieve numbers closer to, or even slightly above, the 27 MPG highway rating. Careful driving habits and consistent maintenance are key to maximizing fuel economy in the NX 300.

How it compares

The NX 300’s fuel economy sits mid-pack within its competitive set. A 2020 Acura RDX SH-AWD, for instance, posts EPA ratings of 21 city/27 highway/23 combined. A BMW X3 xDrive30i achieves roughly the same at 22 city/29 highway/25 combined. Even the Volvo XC60 T5 AWD, known for incorporating efficiency into its design, is close at 20 city/27 highway/23 combined. Lexus buyers may sacrifice some fuel economy versus the BMW, but they often feel they gain long-term dependability and lower running costs. You can access all Lexus fuel economy data on this site.

Tips to maximize efficiency

The turbocharged engine in the NX 300 AWD F Sport is responsive, but also sensitive to throttle input. Avoid aggressive acceleration and hard braking to conserve fuel. Smooth, gradual acceleration will keep the turbocharger from constantly boosting and consuming excess fuel.

Proper tire inflation plays a critical role in fuel efficiency. Check your tire pressure regularly and inflate them to the recommended level, which can be found on the sticker inside the driver’s side doorjamb or in your owner’s manual. Underinflated tires create more rolling resistance, which reduces fuel economy.

Remove any unnecessary weight from your vehicle. Extra cargo in the trunk or back seat adds weight, which forces the engine to work harder and consume more fuel. Clean out any items that you don’t need on a regular basis to improve your gas mileage.

Regular maintenance, including oil changes and air filter replacements, is essential for optimal fuel economy. A clean air filter allows the engine to breathe more easily, while fresh oil reduces friction and improves engine efficiency. Follow the recommended maintenance schedule in your owner’s manual.

Consider using the NX 300’s Eco mode when appropriate. This mode adjusts the engine’s throttle response and transmission mapping to prioritize fuel efficiency. While it may slightly reduce performance, it can help you save fuel in everyday driving situations.
