The top speed of the Lexus NX450h+ is electronically limited to about 125 mph (approximately 201 km/h).
The NX450h+ is a plug-in hybrid SUV that combines a 2.5-liter petrol engine with electric motors to deliver around 302 horsepower. The top speed is limited to balance efficiency, safety, and everyday usability, and can vary slightly by market due to local regulations and software tuning.
Official figures and market variations
Below are the official top-speed figures and the factors that can influence them across regions and conditions.
- Official top speed: around 125 mph (201 km/h) in most markets where the NX450h+ is sold.
- Market differences: minor variations may exist due to local speed limiter settings or regulatory requirements; typical ranges are roughly 120–125 mph (193–201 km/h).
- Test conditions and real-world performance: the published figure is obtained under controlled testing and assumes certain drivetrain and battery states; actual speeds can vary with load, terrain, temperature, and battery state of charge.
In practice, the NX450h+ prioritizes balanced performance and efficiency. The top speed is sufficient for highway cruising, while much of its appeal comes from strong acceleration and EV-assisted torque.
How the powertrain enables high-speed operation

Top speed is124mph for all versions.
What is the difference between NX 350h and 450h+?
The big difference comes in the power of the motors and the battery that feeds them. Where the NX 350h uses a circa-2kWh battery and either two (in front-wheel drive) or three (in all-wheel drive) electric motors, the NX 450h+ exclusively gets a powerful triple-motor AWD setup and an 18.1kWh lithium-ion battery.
