What is the gas range of the NX 450h+?
The NX 450h+ is Lexus’ plug-in hybrid that combines a gasoline engine with an electric drive. When the battery is depleted, the car continues as a conventional hybrid, delivering a substantial but variable gasoline-only range depending on driving conditions. In practical terms, you’ll typically be looking at several hundred miles on petrol after the electric portion is exhausted.
Beyond its electric range, the NX 450h+ blends a 2.5-liter gasoline engine with electric motors and a battery pack to offer both zero-emission miles on battery power and extended trips using gasoline. The exact gasoline range depends on factors such as driving style, terrain, climate, and wheel choice, so manufacturers provide a range rather than a single fixed figure.
Understanding the NX 450h+ powertrain
The NX 450h+ is a plug-in hybrid that uses a gasoline engine in conjunction with one or more electric motors. It carries a sizable battery pack that can deliver a short electric-only range for urban or commuting trips. When the battery is charged, you can operate in electric mode for a portion of your drive; once the battery is depleted, the vehicle operates as a conventional hybrid, relying on the gasoline engine and hybrid systems to extend range and efficiency.
Gasoline range when the battery is depleted
The most relevant numbers for understanding gasoline range are the fuel tank size and the vehicle’s efficiency in hybrid mode. Below is a quick snapshot of the key figures that influence how far you can go on petrol after the battery runs out.
Before the list, note: the following figures are typical benchmarks used by the model in U.S. markets and may vary by market, trim, and wheel size.
- Fuel tank capacity: 14.8 gallons (56 liters).
- Estimated hybrid-mode fuel economy: approximately 30–34 mpg combined (varies by wheel size and trim).
- Gasoline-only range (approximate): about 450–500 miles on a full tank when the battery is depleted, depending on driving style and conditions.
- Note: The EPA does not publish a separate gasoline-range figure for the NX 450h+; real-world range will vary with speed, terrain, temperature, and load.
In practice, the NX 450h+ can cover several hundred miles on gasoline after the electric portion is exhausted, with the exact distance shaped by how you drive and where you drive. The number can swing toward the lower end in heavy traffic and uphill conditions, and toward the higher end on flat highways and economical driving patterns.
Electric range and charging
In addition to its gasoline capability, the NX 450h+ offers a limited electric range that reduces fuel use on short trips. Understanding the electric range and charging options helps quantify total daily usability and how often you’ll rely on electricity versus petrol.
Before the list, here are the core electric-range and charging basics you should know.
- Electric-only range: about 37 miles (60 km) on a full charge in typical testing; actual range varies by market and test cycle (WLTP vs. EPA).
- Battery capacity: around 18 kWh (usable capacity varies by market/version).
- On-board charger: up to 6.6 kW in some markets (some regions may have 3.3 kW as standard).
- Charging times: Level 2 (240V) roughly 2.5–4 hours; Level 1 (120V) charging can take all day (often 12–18 hours) depending on the charger and state of charge.
Concluding the charging section: With a typical Level 2 charger, you can recharge in a few hours, restoring electric-range for everyday commuting, while the gasoline engine provides range for longer trips when needed.
Bottom line
The NX 450h+ is designed to maximize your electric driving for daily use while offering a robust gasoline range for longer journeys. Its fuel tank capacity and hybrid efficiency translate to several hundred miles of petrol range once the battery is no longer contributing, making it flexible for both city driving and road trips.
Summary
The NX 450h+ blends an ~18 kWh battery with a 2.5-liter petrol engine to deliver about 37 miles of electric range and a gasoline-only range of roughly 450–500 miles on a full tank, depending on driving conditions. Real-world range depends on how you drive, climate, terrain, and wheel choice, but the vehicle is designed to offer a seamless transition from electric to gasoline power for extended trips.
