How many kWh is the Lexus NX plug-in hybrid?
The Lexus NX plug-in hybrid (the NX 450h+ in most markets) uses a battery pack rated at 18.1 kWh gross, with roughly 17 kWh usable energy. This capacity underpins its electric-only driving capability and charging behavior.
Battery size and range
The following breakdown highlights the key numbers and what they mean for daily driving.
- Battery capacity: 18.1 kWh gross lithium-ion, with usable energy typically around 17 kWh depending on market and conditions.
- Electric range: In the United States, EPA estimates for the NX 450h+ are around 36–37 miles (58–60 km) on electricity alone; European (WLTP) figures can differ based on testing cycles and conditions.
- Usage in hybrid mode: Once the battery's usable energy is depleted, the vehicle seamlessly blends electric and gasoline power in traditional hybrid operation.
In practice, this means the NX plug-in hybrid can handle many daily commutes without using gasoline, while still offering the extended range benefits of a hybrid when longer trips are needed.
Regional differences and notes
Battery capacity remains essentially 18.1 kWh gross across major markets, but published electric-range figures vary by test cycle (EPA versus WLTP) and vehicle conditioning. Always check the exact specification for your model year and region through official Lexus materials or your dealer.
Why the numbers vary
Different testing methodologies (EPA in the US vs WLTP in Europe) produce different range estimates, and real-world results will depend on factors such as climate, driving style, terrain, and battery state of charge at trip start.
Summary: The Lexus NX plug-in hybrid carries an 18.1 kWh gross battery with about 17 kWh usable energy, offering roughly 36–37 miles (58–60 km) of electric-range in US testing, with regional differences in published figures. For precise numbers, refer to your local Lexus spec sheet for the specific year and market.
