With 36 MPG combined, the 2024 Lexus NX 450h Plus AWD is a good choice for those who want luxury and efficiency in a compact SUV. It’s not a sports car; it’s engineered for drivers who want a refined driving experience, advanced technology, and lower fuel costs. The NX 450h Plus delivers all of this with all-wheel drive.

City and highway performance

The EPA estimates the NX 450h Plus gets 38 MPG in the city and 33 MPG on the highway. The strong city rating shows the benefits of the plug-in hybrid system, which allows for electric-only driving at lower speeds and in stop-and-go traffic. Regenerative braking increases efficiency by capturing energy during deceleration and sending it back to the battery. The highway number, while lower than the city rating, is still respectable for an AWD SUV. Drivers who commute in urban environments will find the NX 450h Plus well-suited to their needs.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Lexus NX 450h Plus AWD at $1,600. This is based on driving 15,000 miles per year and national average fuel prices. Your fuel costs will vary depending on driving habits, local fuel prices, and how often you charge the vehicle. Drivers who consistently use the plug-in capability and maximize electric-only driving will likely see significantly lower fuel costs than the EPA estimate. This figure offers a useful benchmark for comparing the NX 450h Plus to other vehicles.

Real-world expectations

The EPA provides a standardized measure of fuel economy, but real-world MPG will vary. Aggressive driving, frequent acceleration, and carrying heavy loads will hurt fuel efficiency. Smooth driving, proper tire pressure, and minimizing weight can help drivers meet or exceed the EPA estimates. How often the NX 450h Plus is charged will also dramatically affect fuel economy. Owners may rarely visit the gas station if they charge regularly and maximize electric-only mileage.

How it compares

The NX 450h Plus compares well against others in the luxury plug-in hybrid SUV segment. The Volvo XC60 Recharge gets a similar combined MPG. The Lexus often has a longer all-electric range. Examining NX MPG across all years shows Lexus’s commitment to efficiency. The Lincoln Corsair Grand Touring is slightly behind in combined MPG. Choosing between these comes down to brand preference, features, and driving needs. Drivers interested in all Lexus fuel economy data will see efficiency across the brand’s lineup.

Tips to maximize efficiency

Use the NX 450h Plus’s electric-only mode when you can. Short trips and city driving are great for electric power, minimizing fuel use.

Know the drive modes, like Eco mode, which optimizes the vehicle’s settings for maximum fuel efficiency.

Check your tire pressure, as underinflated tires increase rolling resistance. Proper tire inflation will improve MPG, extend tire life, and improve handling.

Avoid aggressive driving, like rapid acceleration and hard braking. Smooth acceleration and predicting traffic will help maintain speed and reduce energy use.

Reduce the use of air conditioning, especially during short trips. The A/C compressor puts a load on the engine (or drains the battery in EV mode) and reduces fuel efficiency, so you should use it carefully. Consider opening a window if the temperature is mild.

Vehicle maintenance is important for fuel economy. Regular oil changes, air filter replacements, and spark plug maintenance ensure that the engine runs well.
