28 MPG combined from the 2023 Lexus NX 250 AWD might not sound astounding, but it represents a sweet spot of efficiency and capability for a specific type of buyer. This isn’t a hybrid designed to shout its lower fuel costs; it’s a comfortable, well-appointed compact SUV aimed at those who want a luxury experience without sacrificing reasonable running costs, especially in regions where all-wheel drive is a genuine asset.

City and highway performance

The EPA estimates for the NX 250 break down to 25 MPG in the city and 32 MPG on the highway. The urban figure is respectable for a vehicle of this size and weight, indicating that the engine’s stop/start system and efficient eight-speed automatic transmission are doing their jobs effectively. The highway number, while not class-leading, allows for confident long-distance cruising without excessive fuel consumption. These numbers directly reflect the engine’s tuning, prioritizing smooth, predictable power delivery over outright acceleration. This appeals to drivers who value a relaxed driving experience and aren’t constantly chasing the fastest 0-60 mph time.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2023 Lexus NX 250 AWD is $1,550. This figure is based on driving 15,000 miles per year and using national average fuel prices. Of course, this number will fluctuate depending on your individual driving habits and the prevailing cost of gasoline in your area. But $1,550 provides a useful benchmark for budgeting and comparing the NX 250 against other vehicles in its class. It’s a tangible dollar amount that helps potential buyers assess the long-term financial implications of ownership.

Real-world expectations

While the EPA figures give a standardized baseline, real-world MPG can vary. Factors such as driving style, terrain, and weather conditions will all impact fuel economy. Aggressive acceleration and frequent hard braking will undoubtedly lower the average. Similarly, driving in hilly areas or during periods of extreme cold can reduce efficiency. However, drivers who adopt a smoother, more deliberate driving style and prioritize consistent speeds should be able to achieve numbers close to the EPA estimates. Regular maintenance, including proper tire inflation and timely oil changes, also plays a crucial role in maintaining optimal fuel economy.

How it compares

The Lexus NX 250 carves out a specific niche in a competitive segment. The Acura RDX, for example, with its turbocharged 2.0L engine, offers a more engaging driving experience but generally returns slightly lower fuel economy, typically around 23 MPG combined in AWD guise. The BMW X3 xDrive30i, another popular choice, also hovers around 24-25 MPG combined. The NX 250, while not the thriftiest, distinguishes itself with a reputation for reliability and a more refined driving experience than many rivals, so this Lexus presents an excellent value for any driver seeking NX MPG across all years.

Of course, the Lexus NX offers hybrid and plug-in hybrid powertrains which vastly improve fuel economy, but those vehicles come with a higher price tag, which changes the financial equation for many buyers. This base NX is for someone who wants Lexus luxury and a comfortable ride but is unwilling or unable to stretch their budget for one of the electrified variants. For that buyer, the NX 250 offers a reasonable balance.

Tips to maximize efficiency

The NX 250’s naturally aspirated engine responds well to gentle acceleration. Avoid abrupt starts and stops, and try to maintain a steady speed whenever possible. This will minimize fuel consumption and contribute to a smoother, more relaxed driving experience, perfectly aligning with the NX’s overall character.

Take full advantage of the NX 250’s Eco mode. This setting adjusts the throttle response and transmission mapping to prioritize fuel efficiency. While it might slightly reduce responsiveness, it can make a noticeable difference in MPG, especially during city driving.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and using more fuel. Check your tire pressure regularly and inflate to the recommended pressure, which can be found on the sticker inside the driver’s side door jamb.

Minimize unnecessary weight. Carrying extra cargo in the trunk or on the roof rack adds weight to the vehicle, which reduces fuel economy. Remove any items you don’t need to improve efficiency. Explore all Lexus fuel economy data to learn more about your vehicle’s performance.

Plan your routes strategically to avoid congested areas and stop-and-go traffic. Idling consumes fuel without traveling any distance. Using navigation apps to find the most efficient route can save you time and money.
