What is the fuel economy of Lexus RX 450h+?
The Lexus RX 450h+ is a plug-in hybrid SUV that blends electric driving with a gasoline engine. Here are the latest, market-specific figures to help you gauge its efficiency. Real-world results will vary with charging habits, climate, and driving style.
Fuel economy at a glance (U.S. market)
The following figures reflect the United States EPA ratings for the RX 450h+ and serve as a baseline for comparison with other plug-in hybrids. Numbers can fluctuate with wheel choice, charge level, and temperature.
- Electric-only range: about 36 miles (58 km) on a full charge
- Combined (gas + electric) fuel economy: approximately 74 MPGe
- Gasoline-only fuel economy (when battery is depleted): about 29 mpg
In daily use, many owners maximize efficiency by charging regularly and using electric power for short commutes, with the gasoline engine stepping in for longer trips. Actual results depend on how you drive and charge.
What this means for drivers
With a plug-in hybrid setup, the RX 450h+ offers significant electric driving for short trips, which can dramatically reduce gasoline consumption if you regularly plug in. When the battery runs low, it switches to conventional hybrid operation, where fuel economy naturally depends on speed, terrain, and load.
Global perspective: Europe and other markets
In Europe and other regions, WLTP testing is used, and figures typically show a strong electric-range capability and lower CO2 emissions compared with pure hybrids. Exact numbers vary by country, trim, and wheel configuration, but buyers can generally expect a similar pattern to the U.S. model: a meaningful electric range and favorable overall efficiency when charged regularly.
How to maximize fuel economy with the RX 450h+
For the best balance of electric range and gasoline efficiency, consider the following practices:
- Charge the battery regularly, ideally daily, to maximize electric driving
- Use Eco or EV modes for city driving to prioritize electric power
- Plan longer trips to minimize frequent cold starts and use highway cruising efficiently
Ultimately, the RX 450h+ is designed to blend practical daily usability with the ability to drive on electricity for shorter trips, while still offering the flexibility of a gasoline engine for longer journeys.
Summary
The Lexus RX 450h+ delivers critical plug-in hybrid efficiency: roughly 36 miles of electric range, about 74 MPGe combined in the U.S., and around 29 mpg gasoline-only when the battery isn’t charged. Europe and other markets follow a similar pattern under WLTP, though exact numbers vary by region. Regular charging and mindful driving can help maximize the electric portion and keep overall fuel use low.
