31 MPG combined is a respectable figure for the 2017 Lexus NX 300h AWD, but it’s important to understand who buys this vehicle and why that number is acceptable, even desirable. The NX 300h isn’t about achieving maximum fuel savings above all else, it’s about delivering acceptable efficiency wrapped in Lexus luxury, refinement, and the peace of mind of Toyota hybrid technology. The NX 300h appeals to a buyer who prioritizes a premium experience and all-weather capability, and who is willing to pay a little extra upfront to save on fuel costs long-term.

City and highway performance

The EPA estimates offer a slightly nuanced picture. The city MPG is rated at 33 MPG, exceeding the combined figure, while the highway MPG comes in at 30 MPG. This is a classic hybrid characteristic. Regenerative braking and electric assist contribute more significantly in stop-and-go city driving. The 2.5L 4-cylinder engine works with electric motors to deliver a smooth and reasonably powerful driving experience. While not a sports car, the NX 300h provides adequate acceleration for daily driving, and the all-wheel drive system, crucial for many buyers in northern climates, enhances confidence in adverse conditions. The automatic (AV-S6) transmission blends with the hybrid powertrain, and the NX 300h’s design will allow it to stand out on the road, delivering an elevated driving experience.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Lexus NX 300h AWD at $1,400. This calculation is based on driving 15,000 miles per year and using national average fuel prices. It’s important to remember that this is an estimate, and your actual fuel costs may vary depending on your driving habits, the type of driving you do (city vs. highway), and local fuel prices, but it serves as a useful benchmark for comparing this vehicle to others in its class. You can view NX MPG across all years to see how 2017 stacks up.

Real-world expectations

EPA estimates are a good starting point, but real-world fuel economy often differs. NX 300h owners frequently report figures close to the EPA estimates, with some experiencing slightly higher numbers, particularly in urban environments. Factors like aggressive acceleration, frequent use of air conditioning, and cold weather can all negatively impact fuel economy. Careful driving habits and regular maintenance are essential to achieving the best possible MPG. The NX 300h’s hybrid system is designed to optimize fuel efficiency automatically, but drivers still play a significant role in maximizing its potential.

How it compares

The NX 300h’s fuel economy stacks up favorably against other small luxury SUVs, particularly those with all-wheel drive. For example, the gasoline-powered NX 200t (now NX 300) with AWD achieves around 24 MPG combined, significantly less than the hybrid. The Acura RDX, a popular competitor, typically gets around 22 MPG combined with its standard V6 engine and AWD. Even smaller competitors like the BMW X1 xDrive28i, get around 25 MPG combined. The Lexus’s emphasis on a luxury interior and a comfortable ride, along with its efficient hybrid powertrain, gives car buyers efficiency and refinement.

Tips to maximize efficiency

Gentle acceleration is key to maximizing the NX 300h’s fuel efficiency. Avoid sudden bursts of speed and try to anticipate traffic flow to maintain a steady pace. The hybrid system performs best when operated smoothly, allowing the electric motors to assist the gasoline engine effectively.

Use the NX 300h’s “Eco” driving mode. This mode adjusts the throttle response and climate control settings to prioritize fuel efficiency. While it may slightly reduce performance, it can lead to improvements in MPG, particularly during city driving.

Proper tire inflation is critical. Check your tire pressure regularly and maintain it at the recommended level, which is typically found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces fuel economy.

Minimize the use of accessories like air conditioning and heated seats, particularly during short trips. These features put extra strain on the engine and reduce fuel efficiency. When possible, use the air conditioning sparingly and opt for natural ventilation.

Regular maintenance is essential for optimal fuel economy. Ensure that your NX 300h receives scheduled service, including oil changes, air filter replacements, and spark plug inspections. A well-maintained engine operates more efficiently.
