How much horsepower does the Lexus NX 300h hybrid have?
The NX 300h's total system horsepower is 194 hp (145 kW).
The hybrid pairs a 2.5-liter Atkinson-cycle engine with an electric motor and a CVT, delivering a blend of usable performance and efficiency. This article explains where that horsepower comes from and how it translates to real-world driving across markets.
Powertrain basics
The NX 300h uses a 2.5-liter Atkinson-cycle inline-4 engine paired with an electric motor and a continuously variable transmission. Lexus lists a total system output of 194 hp for the hybrid powertrain, a figure that reflects the combined capability of gas and electric propulsion.
What contributes to the horsepower
Two primary components drive the NX 300h's power: the gasoline engine and the electric motor. The following list highlights their roles in achieving the overall figure.
- Gasoline engine: 2.5-liter Atkinson-cycle inline-4 provides the baseline power for the hybrid system
- Electric motor: delivers propulsion assist, boosts torque at low speeds, and enables regenerative braking
- Hybrid control system: blends engine and motor output through the CVT for smooth, efficient acceleration
These components work together to deliver the NX 300h's total horsepower rating, while also prioritizing efficiency and everyday usability.
Market variations and real-world performance
The official horsepower figure is largely consistent across markets, though slight variations can appear in local listings due to year tweaks or regional testing standards. In most regions, Lexus cites 194 hp (145 kW) for the NX 300h combined output. Real-world performance depends on factors such as drivetrain layout (front-wheel drive vs all-wheel drive), battery state, and driving conditions.
Summary
Final takeaway: The Lexus NX 300h hybrid delivers 194 hp of total system power, achieved by the collaboration of a 2.5-liter Atkinson-cycle gasoline engine and an electric motor, managed by a CVT. This setup aims to balance adequate acceleration with fuel efficiency, suitable for daily driving and urban commuting.
