How fast can a Lexus RX go?

In everyday driving terms, the current Lexus RX lineup is electronically limited to about 125 mph, with the high-performance hybrid RX 500h delivering quicker acceleration while still sharing that top-speed ceiling. Exact figures vary by model year, drivetrain, and market.


Top speeds by trim (approximate, latest model years)


The following figures reflect common specifications for recent RX models sold in the United States. Top speed is largely governed by an electronic limiter, and actual limits can differ by market or optional equipment.



  • RX 350 — Top speed about 125 mph (2019–present generations).

  • RX 450h — Top speed about 125 mph (hybrid variant).

  • RX 500h — Top speed about 125 mph (performance-oriented hybrid).


While the top speed remains similar across trims, the way each model gets there varies, with the RX 500h offering stronger off-the-line performance thanks to its hybrid powertrain.


0–60 mph times by trim (approximate, latest model years)


0–60 mph figures give a sense of acceleration rather than top speed. The numbers below are approximate and depend on factors like drivetrain configuration, tires, and testing conditions.



  • RX 350 — Roughly 6.8–7.6 seconds to 60 mph.

  • RX 450h — Roughly 7.2–7.9 seconds to 60 mph.

  • RX 500h — Roughly 5.5–6.0 seconds to 60 mph.


Notes: Hybrid and performance variants accelerate faster due to additional electric motor torque, while all models share the same general top-speed limit. Market year, trim level, and tire choice can shift these times by tenths of a second.



Several factors explain why different RX models behave differently on the road. Power output, drivetrain configuration, weight, and gearing all play roles, as do electronic controls that govern top speed and throttle response.


Powertrain and weight


Turbocharged engines in the RX 350 deliver strong mid-range power, while the RX 450h and RX 500h use hybrid systems that add immediate torque from electric motors. The added weight of hybrids can affect acceleration versus pure combustion models, but the instant torque from electric motors usually offsets that drawback at launch.


Market and model-year variations


Top-speed limits and performance figures can differ by country, emission regulations, and model-year updates. Always check the official spec sheet for your specific vehicle and market to get exact numbers.


Tire and testing conditions


Speed and acceleration figures vary with tire type, road conditions, and whether the measurements come from manufacturer testing or independent testing. Real-world numbers can differ from EPA or official tests.



Speed limits, fuel economy, and ride comfort are important considerations for daily use. The RX lineup prioritizes a balance of luxury, efficiency, and usable performance rather than canyon-carving speed, and most buyers will experience the vehicle as quick enough for everyday highways and merging.


Safety and legality


Most markets enforce speed limits far below the cars’ top speeds. It’s important to drive within posted limits and maintain full awareness of passengers, weather, and road conditions.


Fuel economy and ownership costs


Hybrid variants typically offer better city efficiency, which can influence overall cost of ownership. Performance gains should be weighed against fuel use and maintenance considerations.



The Lexus RX lineup generally tops out around 125 mph across its trims, with the RX 500h delivering quicker acceleration while not surpassing the same top-speed limit. 0–60 times range from the high 6 seconds for the RX 350 to the mid-5 seconds for the RX 500h. Exact numbers vary by model year, market, drivetrain, and tires, so consult the official spec sheet for your specific vehicle to get precise figures.
