25 MPG combined is a reasonable figure for the 2019 Lexus NX 300. This compact luxury crossover prioritizes comfort, style, and brand reputation over maximizing fuel efficiency. Owners appreciate its sculpted exterior, quiet cabin, and the reliable ownership experience Lexus provides. Fuel economy is a consideration, but often ranks below reliability and resale value.

City and highway performance

The EPA estimates offer a detailed view of the NX 300’s fuel consumption. The city rating is 22 MPG, reflecting the demands of stop-and-go traffic. The turbocharged 2.0L engine works harder in city driving, needing frequent boosts of power. On the open road, the NX 300 performs better, reaching 28 MPG on the highway. This figure is common for vehicles in this class. Longer highway trips benefit from the NX 300’s aerodynamics and the transmission settling into an efficient cruising gear.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Lexus NX 300 is $2,300. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on driving habits and local fuel prices, but this provides a benchmark.

Real-world expectations

While the EPA estimates are a useful baseline, real-world fuel economy can vary. Most NX 300 drivers report figures close to the EPA numbers, though often slightly lower. Expect around 21-24 MPG in mixed driving. Reaching the EPA’s 28 MPG highway number requires consistent speeds and a light foot on the accelerator. Aggressive driving, frequent short trips, and heavy loads will negatively impact mileage. All Lexus fuel economy data is available if you want to dig deeper.

How it compares

The NX 300’s fuel economy is average for its class. The Acura RDX, with its turbocharged 2.0L engine, achieves an EPA-estimated 24 MPG combined. The BMW X3 sDrive30i (rear-wheel drive) performs slightly better at 25 MPG combined, but the xDrive30i (all-wheel drive) matches the NX 300’s 25 MPG. The Mercedes-Benz GLC 300 also achieves around 24 MPG combined. The NX 300h hybrid model delivers significantly better mileage, but at a premium. Be sure to compare NX MPG across all years to see how it stacks up.

Tips to maximize efficiency

The NX 300’s turbocharged engine responds well to smooth acceleration. Avoid quick bursts of speed and anticipate traffic flow to minimize braking. Gradual acceleration will keep you out of the turbo’s boost range, improving MPG.

Ensure your tires are inflated to the recommended pressure listed on the driver’s side doorjamb. Underinflated tires increase rolling resistance, making the engine work harder. Check tire pressure regularly, especially when the temperature changes.

Reduce your use of air conditioning, especially during shorter trips. The AC compressor places a load on the engine. Driving with the windows down or using the ventilation system can improve fuel economy.

Remove unnecessary weight from the vehicle. Extra cargo adds to the vehicle’s weight, decreasing fuel efficiency. Regularly declutter your NX 300 to reduce weight and improve MPG. Also, consider removing aftermarket roof storage boxes.

Schedule regular maintenance for your NX 300. A well-maintained engine is more efficient. Follow the recommended maintenance schedule in your owner’s manual, including oil changes, air filter replacements, and spark plug maintenance. Neglecting these tasks can decrease fuel economy and lead to costly repairs.
