2026 NX fuel economy by trim

From lexus.com's 2026 NX trim list (combined MPG or MPGe estimate, horsepower and drivetrain for each of 15 trims), read November 2, 2026. Actual mileage will vary.

The EPA records behind the numbers

Miles per gallon. From fueleconomy.gov (U.S. EPA and Department of Energy) records for the 2026 Lexus NX, read November 2, 2026: the NX 350 versions are 2.4L turbocharged four-cylinders with an 8-speed automatic, and the NX 350h versions 2.5L four-cylinder hybrids with a continuously variable automatic. Fueleconomy.gov listed no 2026 NX 450h+ record on that date.

Three powertrains

NX 350: lexus.com lists a 2.4-liter turbocharged in-line four with 275 horsepower and a 0-60 mph time of 6.6 seconds. All four 2026 NX 350 trims are all-wheel drive, and lexus.com lists each at 24 combined mpg.

NX 350h: a 2.5-liter in-line four hybrid with 240 net combined horsepower. Lexus.com lists front-wheel-drive versions at 40 combined mpg and AWD versions at 39 combined; fueleconomy.gov rates them 42 / 38 / 40 and 41 / 37 / 39 (city / highway / combined).

The NX 450h+ plug-in hybrid

Lexus.com lists the NX 450h+ with 304 net combined horsepower, all-wheel drive, a 0-60 mph time of 6.0 seconds, 84 combined MPGe, and a manufacturer-estimated all-electric driving rating of 37 miles. It is offered in Premium, Luxury and F SPORT Handling trims.

Lexus.com rates the NX 450h+ in MPGe (miles per gallon equivalent) rather than mpg, and notes that beyond its electric driving it can also operate as a conventional gas/electric hybrid. Its MPGe figure is a different measure from the mpg ratings of the NX 350 and NX 350h, so the two are not a like-for-like comparison.

Why your NX's MPG drops in winter

Fueleconomy.gov says conventional gasoline vehicles can expect a 10% to 20% fuel economy loss in city driving and 15% to 33% on short trips in cold weather, and hybrids typically 20% to 40% in city driving and 25% to 45% on short trips. Its reasons:

From fueleconomy.gov's Fuel Economy in Cold Weather page, read November 2, 2026.

Getting closer to the rated numbers

Fueleconomy.gov's cold-weather advice: park in a warmer place such as a garage, combine trips so you drive less often with a cold engine, keep warm-up idling short (it notes most manufacturers recommend driving off gently after about 30 seconds), use seat warmers and defrosters only as needed, check tire pressure regularly, use the oil your manufacturer recommends for cold weather, and remove roof racks when you are not using them.

Year-round, it says aggressive driving (speeding, rapid acceleration and braking) can lower gas mileage by roughly 15% to 30% at highway speeds and 10% to 40% in stop-and-go traffic, that mileage usually decreases rapidly above 50 mph, and that an extra 100 pounds in a vehicle could reduce mpg by about 1%.
