What is the range of the RX 450h+ plug-in hybrid?
The RX 450h+ offers roughly 42 miles (about 68 kilometers) of electric-only range in U.S. EPA testing and about 37–47 miles (60–75 kilometers) in European WLTP testing, with an 18.1 kWh battery. Real-world range varies with conditions and driving style.
This article explains the official figures, how they’re measured, and what factors can affect the actual range you’ll experience with the RX 450h+.
Official range figures by market
These figures reflect common regional test cycles and are typical references for buyers. Actual range can vary by wheel size, trim, and climate controls.
- EPA-rated electric range (United States): about 42 miles (≈68 kilometers) on a full charge.
- WLTP-rated electric range (Europe/UK): about 37–47 miles (≈60–75 kilometers), depending on wheels and trim.
In practice, many owners report real-world ranges that are somewhat below these figures, especially in cold weather or with demanding climate control use.
Battery and charging basics
Key hardware and charging capabilities influence how quickly you can restore electric range between trips.
- Battery capacity: 18.1 kWh (net usable capacity varies by market).
- Onboard charger: typically up to around 3.3 kW for AC charging in many markets.
- DC fast charging: not supported on RX 450h+; charging relies on AC Level 2 charging.
- Estimated charging times: roughly 4–6 hours on a Level 2 (240V) home charger, depending on starting state of charge and power supply.
Owners should plan charging around daily driving needs, noting that higher-power Level 2 charging improves convenience but may not always be available.
What affects the range in everyday use
Several factors can cause the actual electric range to differ from official numbers. The following items commonly have the biggest impact:
- Climate control and cabin heating/cooling consumption.
- Ambient temperature and battery temperature management.
- Heavy driving, rapid acceleration, and high-speed cruising.
- Wheel size, tire choice, and aerodynamics (larger wheels can reduce range).
- State of charge at the start of a trip and driving route) (city vs highway).
Even with these variables, the RX 450h+ remains competitive in its class for a plug-in hybrid, offering a meaningful electric-only portion for daily commuting in many markets.
Bottom line
For most buyers, the RX 450h+ provides approximately 42 miles of electric range in the U.S. and roughly 37–47 miles under WLTP in Europe, backed by an 18.1 kWh battery. Real-world range will depend on weather, driving style, and how much you rely on climate control.
Summary
The RX 450h+ delivers a practical plug-in hybrid range centered around ~40 miles of electric-only capability, with regional test cycles showing EPA at about 42 miles and WLTP in the mid-40s miles. Battery capacity is 18.1 kWh, charging is AC-only (no DC fast charging), and real-world range varies with conditions and usage.
What is the electric range of the Lexus RX 450h+?
38-mile
The system provides luxury performance and consistent acceleration off the line with an estimated 6.2 second 0-60 time. The RX 450h+ has an EPA-estimated 38-mile driving range rating on electric power only.
What are common RX 450h+ problems?
Lexus RX 450h battery drain problem
Some drivers report the battery of their RX 450h goes flat after two to three weeks of not being used, which is especially inconvenient in a hybrid car because the battery can't be jump-started.
How many miles per gallon does the RX 450h+ plug-in hybrid get?
The Lexus RX 450h+ plug-in hybrid gets an EPA-estimated 83 MPGe combined (gas + electric) and 35 mpg combined on gasoline alone. It also has an all-electric driving range of up to 37 miles on a full charge.

What is the difference between Lexus rx450h+ and 500h+?
The main difference is that the RX 450h+ is a plug-in hybrid (PHEV) focused on efficiency and electric-only driving, while the RX 500h is a performance hybrid with a more powerful, turbocharged engine and a traditional automatic transmission. The 450h+ offers 37 miles of electric range and an e-CVT, prioritizing long-term fuel savings. The 500h is built for sportier performance, with higher horsepower and torque from its turbo engine, making it faster and more engaging to drive, and uses a conventional 6-speed automatic transmission.
RX 450h+ (Plug-in Hybrid)
- Powertrain: 2.5L 4-cylinder engine with two front electric motors and one rear motor, using an e-CVT.
- Performance: 304 horsepower, 0-60 mph in about 6.2 seconds, and a 37-mile all-electric range.
- Focus: Fuel efficiency and the ability to run on electricity alone for daily commutes before switching to a hybrid mode.
- Driving Feel: Smooth and quiet, especially in EV mode.
RX 500h (Performance Hybrid)
- Powertrain: 2.4L turbocharged 4-cylinder engine with an integrated electric motor, paired with a 6-speed automatic transmission.
- Performance: Higher horsepower and torque, with a faster 0-60 mph time of around 6.0 seconds.
- Focus: Sporty performance and a more traditional driving experience with the turbo engine and automatic gearbox.
- Driving Feel: More powerful acceleration and a sportier feel, with the transmission providing a more conventional shift experience.
Which one is right for you?
- Choose the RX 450h+ if you prioritize saving money on fuel and want the ability to drive on electric power alone for many of your daily trips, and you value long-term reliability.
- Choose the RX 500h if you prioritize performance and a sportier driving feel over fuel efficiency, and you prefer a more conventional hybrid setup with a turbocharged engine and traditional automatic transmission.
