24 MPG combined in the 2019 Lexus NX 300 AWD isn’t going to set any records, but it’s perfectly acceptable for a stylish, comfortable, and well-equipped compact luxury SUV. NX 300 buyers prioritize premium features, Lexus reliability, and distinctive design over squeezing every last mile from a gallon of gasoline. They want an upscale experience, and reasonable fuel economy supports that without being a primary motivator.

City and highway performance

The EPA estimates the NX 300 AWD at 22 MPG in the city and 28 MPG on the highway. The city figure is perhaps the more useful metric for understanding how this vehicle will perform in everyday use. Commuters navigating stop-and-go traffic will likely see numbers closer to that 22 MPG mark. The highway figure, on the other hand, reflects a more consistent speed and fewer acceleration demands. The 2.0L turbocharged four-cylinder engine and six-speed automatic transmission are tuned for smooth, predictable power delivery rather than outright efficiency. This means that passing and merging on the highway are handled with ease, but at the expense of maximizing fuel savings. The transmission is responsive enough; however, the priority is clearly placed on smoothness and quiet operation, key attributes for Lexus buyers.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2019 Lexus NX 300 AWD is $2,400. This figure is based on driving 15,000 miles per year, with 45% of those miles driven in the city and 55% on the highway. The calculation also uses national average fuel prices, which can fluctuate considerably depending on location and time of year. Remember that this is an estimate. Your actual fuel costs will vary depending on your driving habits, the type of driving you do (city vs. highway), and the price of gasoline in your area. The $2,400 figure provides a useful benchmark for comparing the NX 300’s fuel costs against other vehicles in its class.

Real-world expectations

The EPA estimates provide a standardized baseline, but real-world fuel economy often deviates. Many NX 300 owners report figures close to the EPA estimates, but several factors can influence this outcome. Aggressive driving, frequent short trips, and prolonged idling will all negatively impact fuel efficiency. Gentle acceleration, consistent highway speeds, and regular maintenance can help drivers achieve or even slightly exceed the EPA numbers. The weight of passengers and cargo also matters, as does tire pressure. The AWD system, while providing added traction and stability, also adds weight and slightly increases drivetrain friction, contributing to a marginal decrease in fuel economy compared to the FWD version.

How it compares

The NX 300’s fuel economy is competitive, but not class-leading. An Acura RDX with a similar 2.0L turbo four-cylinder achieves around 23 MPG combined, putting it neck and neck with the NX. The BMW X3 xDrive30i, with its turbocharged 2.0L engine, manages a comparable 24 MPG combined. The hybrid versions of these competitors offer significantly better fuel efficiency. The Lexus NX 300h, for example, delivers around 31 MPG combined thanks to its hybrid powertrain. For buyers who prioritize fuel economy, the hybrid versions of these SUVs are the clear choice. Those who appreciate the NX 300’s styling, interior quality, and Lexus reputation might find the slightly lower fuel economy an acceptable trade-off.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the NX 300. Avoid sudden bursts of speed and try to maintain a smooth, consistent pace. The turbocharged engine is responsive, but hard acceleration will quickly deplete fuel.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure regularly and inflate them to the recommended level, which can be found on a sticker inside the driver’s side doorjamb. This is especially important if you regularly carry passengers or cargo.

Reduce unnecessary weight. Carrying extra items in your vehicle adds weight, which reduces fuel efficiency. Remove any unnecessary items from your trunk and back seats to lighten the load.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long trips. Avoid frequent acceleration and braking, which can waste fuel. The adaptive cruise control system in the NX 300 can be particularly helpful in maintaining a safe and fuel-efficient distance from other vehicles.

Consider the front-wheel drive version. The AWD offers enhanced traction in inclement weather, but it impacts fuel economy. If you live in an area with mild weather conditions, the FWD version of the NX 300 might be a better choice for maximizing fuel efficiency. For all Lexus fuel economy data, explore our main hub.
