How many miles per gallon does a Lexus nx450h+ get?
The Lexus NX 450h+ is a plug-in hybrid, so its efficiency is shown as MPGe when the battery is in use and as gasoline mpg once the battery is depleted. In general, expect roughly 80–90 MPGe combined with about 36 miles of electric range, and around 30–34 mpg on gasoline when the battery isn’t charged. Exact figures depend on model year, drivetrain, and driving conditions.
Like many modern plug-in hybrids, the NX 450h+ blends electric propulsion with a gasoline engine. The numbers you see from the EPA reflect both how far you can drive on electricity alone and how efficiently the vehicle uses gasoline once the battery’s charge is used up. Below are the typical figures for recent NX 450h+ models and notes on what drives variations in those numbers.
EPA fuel-economy numbers for the NX 450h+
Below is a concise summary of the standard EPA ratings you’ll encounter for recent NX 450h+ models. These figures can vary by year, trim, and drivetrain, so use them as a baseline rather than a guarantee for every individual car.
- Combined MPGe (electric + gasoline): about 80–90 MPGe
- Electric-only range (EPA-estimated): about 36 miles
- Gasoline-only fuel economy after battery depletion: about 30–34 mpg
These numbers illustrate how the NX 450h+ performs when you regularly charge the vehicle and drive within its electric range. If you rarely charge, your overall efficiency will lean more toward the gasoline mpg figure once the battery is drained.
What MPGe means for plug-in hybrids
MPGe stands for miles per gallon equivalent and measures how far a vehicle can travel using a unit of energy equal to one gallon of gasoline. For plug-in hybrids like the NX 450h+, MPGe combines energy use from both the electric motor and the gasoline engine. A higher MPGe indicates greater overall efficiency when the battery and gasoline are both in play.
Maximizing efficiency: driving and charging tips
Owners can influence real-world fuel economy by charging the battery regularly, planning trips to stay within the electric range, and using efficiency-focused settings. The following tips can help you approach the EPA numbers more often:
- Charge the vehicle as often as possible to maximize electric driving time
- Plan daily routes to stay within the NX 450h+’s electric range
- Use Eco or similar efficiency modes and pre-condition the cabin while still plugged in
- Maintain proper tire pressure and smooth, steady acceleration
- Avoid aggressive driving that rapidly drains the battery or increases load
By adopting these practices, you’re more likely to see higher MPGe and longer electric ranges in real-world driving, bringing you closer to the upper end of the EPA estimates.
Notes on model-year variations and how to check exact figures
EPA ratings can change slightly from year to year due to packaging, battery capacity, or drivetrain refinements. For the most precise numbers for a specific vehicle, consult fueleconomy.gov or the official Lexus specifications for that model year and drivetrain configuration.
Summary
The Lexus NX 450h+ blends a gasoline engine with an 18–ish kWh battery to deliver strong efficiency for a plug-in hybrid. Expect roughly 80–90 MPGe combined with about 36 miles of EV range, and around 30–34 mpg when the battery isn’t charged. Real-world results depend on how often you charge, your driving style, and road/traffic conditions. For exact, year-specific figures, check the EPA’s fueleconomy.gov database or Lexus’s official spec sheets.
What is the difference between Lexus RX 450h and 450h+?
The main difference is that the "450h" refers to a standard hybrid model, while the "450h+" specifically denotes a plug-in hybrid (PHEV) model that can be charged externally for a significant electric-only driving range. The "+" model typically has a more powerful plug-in hybrid system and a higher price point, but offers greater efficiency and the ability to run on pure electricity for daily commutes. The regular 450h uses a self-charging hybrid system without external charging capabilities.
Lexus 450h+ (Plug-in Hybrid)
- Electric Range: Offers a manufacturer-estimated 37 to 38 miles of all-electric driving range after being charged externally.
- Performance: Delivers stronger performance and acceleration, with a combined 304 to 308 horsepower.
- Fuel Efficiency: Generally more efficient due to its ability to use electric power for short trips, but will still use premium unleaded gasoline.
- Charging: Requires external charging to utilize its full electric range.
- Price: Typically has a higher starting price than the 450h model.
Lexus 450h (Standard Hybrid)
- Electric Range: Does not have a dedicated all-electric driving range because it is a self-charging hybrid, not a plug-in hybrid.
- Performance: Has a lower net horsepower compared to the 450h+ model, with a total of 246 horsepower for the RX 350h model.
- Fuel Efficiency: Provides excellent fuel efficiency for everyday driving through its self-charging system, with no need for external charging.
- Charging: Does not need to be plugged in; it charges its battery using the gas engine and regenerative braking.
- Price: Is more affordable than the 450h+ model.
What is the fuel economy of the Lexus NX 450h+?
Meet the most powerful Lexus model on this list - the plug-in hybrid 2025 Lexus NX 450h+ with a fuel efficiency rating of 6.3/7.1 L/100KM (city/highway) and a combined rating of 6.7 L/100KM.
What is the real mpg of the Lexus NX hybrid?
The official combined fuel economy figure of the Lexus NX300h is 54.3mpg. Interestingly, the official extra-urban figure is 55.4mpg and the urban figure is 53.3mpg – so not much difference – officially – between the three. Our actual real-life average after a week of driving the NX hybrid was 31.1mpg.
What is the real range of Lexus NX 450h+?
between 42 and 46 miles
They are powered by an 18.1kWh battery which is on the large side for this class of plug-in hybrid. Thanks to its big battery, the NX 450h+ has a range of between 42 and 46 miles in the combined official WLTP tests, with CO2 emissions between 21 and 25g/km and fuel economy between 256.8 and 313.8mpg.
