The 2019 Lexus NX 300h AWD gets 31 MPG combined, making it a good choice for luxury buyers who want fuel efficiency and all-weather capability. It’s not a sports SUV for track days, and it’s not an off-roader either. Instead, the NX 300h balances a comfortable ride, a nice interior, and all-wheel drive with efficient fuel consumption. This makes it a contender for urban professionals, small families, and empty nesters who value practicality and a touch of luxury.
City and highway performance
The EPA numbers show the NX 300h AWD’s strengths, especially in city driving. It gets 33 MPG in the city, which shows the benefits of its hybrid powertrain. This powertrain allows for electric-only operation at lower speeds and in stop-and-go traffic. The 2.5L 4-cylinder engine and the electric motor(s) work together for adequate acceleration, and regenerative braking reclaims lost energy. The NX 300h gets an estimated 30 MPG on the highway. While this is a bit less than its city MPG, it’s still good for an all-wheel-drive SUV. The automatic (AV-S6) transmission shifts smoothly and efficiently, which helps the NX 300h save fuel.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2019 Lexus NX 300h AWD is $1,400. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary, depending on your driving, the fuel you buy, and local fuel prices. But the EPA estimate is a good way to compare the NX 300h AWD to other vehicles. For those considering the NX 300h, this lower annual fuel cost is better than comparable non-hybrid SUVs and even some other hybrid models with lower MPG figures.
Real-world expectations
The EPA provides standardized numbers, but real-world fuel economy can be different. Driving style, terrain, weather, and vehicle load all matter. NX 300h owners often report MPG close to the EPA estimates, especially those who accelerate smoothly and anticipate traffic. Aggressive driving, using the air conditioning often, and carrying heavy loads will reduce fuel economy. However, if you drive carefully, getting the EPA’s 31 MPG combined rating is possible for most drivers.
How it compares
The NX 300h AWD does well in the compact luxury hybrid SUV class. The Acura RDX offers more engaging driving, but gets around 23 MPG combined, so it uses more fuel. The BMW X3 xDrive30e, a plug-in hybrid, has some electric range but gets around 25 MPG combined as a standard hybrid. The Lexus UX 250h AWD is smaller and less expensive, and it gets 41 MPG combined, but it has less space than the NX. The NX 300h AWD offers luxury, practicality, and good fuel economy, so it’s a good choice for buyers who want an efficient and comfortable SUV.

Tips to maximize efficiency
Accelerate gently to maximize fuel economy in the NX 300h. The hybrid system is most efficient when you accelerate smoothly and avoid hard starts. Let the electric motor work first, then increase the throttle as needed. Watch the power meter to see when the engine starts versus when it’s electric-only.
Use the NX 300h’s drive modes. “Eco” mode saves fuel by reducing throttle response and changing climate control. It might feel less responsive, but using Eco mode in the city can improve your MPG. “Normal” mode is good for everyday driving, and “Sport” mode gives you faster acceleration but uses more fuel.
Keep your tires inflated. Check your tire pressure often and keep it at the recommended pressure on the doorjamb sticker. Underinflated tires increase rolling resistance, hurting fuel economy. Proper tire inflation improves MPG and extends tire life.
Reduce weight in the vehicle. Carrying heavy items in the trunk reduces fuel economy. Remove items you don’t need regularly to lighten the load and improve MPG. Also avoid using roof racks unless necessary, as they increase drag.
