24 MPG combined is the headline for the 2026 Lexus NX 350 AWD F Sport. This figure balances sporty ambition and luxurious practicality for a compact luxury SUV. This isn’t a vehicle chasing hybrid hyper-efficiency, nor is it a gas-guzzling machine. The NX 350 AWD F Sport uses its 2.4-liter turbocharged inline-four to deliver lively performance and respectable real-world economy. This is what its target demographic of affluent urban and suburban professionals expects. They want a dynamic driving experience coupled with the reliability that comes from a Lexus badge, and they understand that a premium experience, enhanced by AWD and F Sport tuning, comes with certain engineering trade-offs.

City and highway performance

Breaking down the 24 MPG combined figure reveals 21 MPG in the city and 28 MPG on the highway. In city driving, the NX 350 AWD F Sport’s turbocharged 2.4L engine, paired with its 8-speed automatic transmission, works efficiently to manage stop-and-go traffic. While 21 MPG in urban environments isn’t class-leading, it’s competitive for a vehicle with all-wheel drive and a performance-oriented engine. The turbocharger ensures immediate torque delivery, minimizing the need for heavy throttle applications that would otherwise significantly diminish fuel economy. This urban efficiency target reflects the reality of its ownership base, who often navigate congested city streets and suburban gridlock.

On the open highway, the 28 MPG rating shines brighter. The 8-speed automatic transmission allows the engine to operate at lower RPMs, reducing fuel consumption during extended cruises. The NX 350 AWD F Sport isn’t built for autobahn-blasting, but its highway manners are composed, quiet, and stable, making it an excellent long-distance companion. This highway figure is particularly appealing to those who commute substantial distances or frequently embark on weekend getaways, where consistent, efficient cruising is a priority.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,400 for the 2026 Lexus NX 350 AWD F Sport. This figure is calculated based on an assumption of 15,000 miles driven per year, split between 45% highway and 55% city driving, and using national average fuel prices. For the typical NX 350 F Sport buyer, this $2,400 per year effectively translates to roughly $200 per month in fuel expenses. While not insignificant, this cost is generally perceived as acceptable given the vehicle’s luxury positioning, powerful engine, standard all-wheel drive, and engaging driving dynamics. It’s the cost of enjoying a premium, responsive driving experience from a brand known for its reliability and refinement.

Real-world expectations

Owners of the NX 350 AWD F Sport can generally expect their real-world fuel economy to closely align with the EPA estimates, assuming a disciplined driving style. Enthusiastic driving will inevitably dip below the 24 MPG combined figure, as the F Sport tuning and turbocharged engine invite spirited acceleration. However, the sophisticated powertrain management and refined transmission do a commendable job of optimizing fuel use even during spirited excursions. For those prioritizing efficiency, smooth throttle inputs and judicious use of the Sport S+ mode will yield numbers very near those published. Conversely, heavy-footed drivers who frequently use the full 275 horsepower will likely see city numbers closer to 19-20 MPG and highway figures in the low 20s. Terrain, traffic density, and proper tire inflation also play significant roles in these real-world variations.

How it compares

The 2026 Lexus NX 350 AWD F Sport 2.4L 4-cyl occupies a competitive niche, and its fuel economy reflects its positioning. Consider its German rivals: the BMW X3 xDrive30i, with its 2.0L turbo-four, achieves 24 MPG combined (21 city/28 highway), mirroring the NX 350 almost exactly. The Audi Q5 45 TFSI quattro, also with a 2.0L turbo-four, lands at 26 MPG combined (22 city/29 highway), offering a slight edge. The Mercedes-Benz GLC 300 4MATIC, featuring a mild-hybrid 2.0L turbo-four, achieves 28 MPG combined (24 city/31 highway), showcasing the benefit of its electrification. What these comparisons reveal is that the NX 350, despite its slightly larger 2.4L engine, holds its own in terms of fuel economy against its direct competitors. Its buyers aren’t cross-shopping it against a Toyota RAV4 Hybrid, they’re comparing it to other compact luxury SUVs with similar performance aspirations and all-wheel-drive configurations. For them, the NX’s 24 MPG is perfectly acceptable, especially when weighed against Lexus’s renowned build quality and dealer experience.

Tips to maximize efficiency

Maintaining consistent speeds, particularly on the highway, greatly benefits the NX 350’s fuel economy. Engaging cruise control on flatter sections allows the 8-speed automatic to maintain its optimal gear ratio without unnecessary shifts or throttle adjustments, keeping the engine in its most efficient band.

Avoid excessive idling, especially in colder weather. While the NX 350 doesn’t feature a true start-stop system on this specific powertrain, shutting off the engine when waiting for extended periods, such as in a drive-thru or waiting for a passenger, prevents unnecessary fuel consumption.

Regular maintenance is crucial for optimal fuel efficiency. Ensure you adhere to Lexus’s recommended service intervals for oil changes, air filter replacements, and tire rotations. A well-maintained engine and drivetrain operate more efficiently.

Pay close attention to your tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consequently consuming more fuel. Check your tire pressure regularly, especially as seasons change, and inflate to the manufacturer’s recommended PSI.
