107 MPG combined is a remarkable figure for any vehicle, and the 2023 Lexus RZ 450e AWD (with 18-inch wheels) uses this efficiency to offer a luxury electric experience unlike any other. This isn’t about pinching pennies for budget-conscious drivers; it’s about embracing cutting-edge technology and reducing your environmental footprint without sacrificing a premium driving experience. The RZ 450e targets a specific buyer: someone who values sustainability, advanced technology, and the Lexus brand’s reputation for reliability and comfort more than ultimate driving range or bargain-basement pricing.

City and highway performance

The EPA estimates the RZ 450e achieves 115 MPG in the city and 98 MPG on the highway. This difference highlights the EV’s benefit in stop-and-go traffic, where regenerative braking captures energy that would otherwise be lost in a traditional combustion engine. The lower highway rating is typical for EVs, as aerodynamic drag increases significantly at higher speeds and requires more energy to overcome. These figures are estimates, and your actual mileage will vary based on driving style, weather conditions, and terrain. Aggressive acceleration and frequent use of climate control can significantly reduce your EV’s range and MPGe.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Lexus RZ 450e AWD at $700. This calculation is based on driving 15,000 miles per year and using the national average electricity price. Of course, this figure can fluctuate depending on your local electricity rates and driving habits. Charging at home during off-peak hours, if possible, can substantially reduce your annual charging expenses. This $700 figure doesn’t account for potential savings in maintenance costs, as EVs generally require less upkeep than gasoline-powered vehicles, with fewer moving parts and no need for oil changes or spark plug replacements.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world MPGe can vary. The RZ 450e’s range is also something to consider alongside MPGe. Drivers who frequently undertake long journeys exceeding its predicted range may find range anxiety a concern. For those who primarily drive in urban environments or have access to convenient charging options at home or work, the RZ 450e’s range and MPGe figures should prove more than adequate. The RZ’s intuitive energy consumption display helps drivers monitor their efficiency and adjust their driving style accordingly. You can review RZ MPG across all years to see how efficiency compares.

How it compares

The RZ 450e enters a competitive landscape, facing off against other luxury electric SUVs. The Cadillac LYRIQ, for example, boasts a similar size and luxury feel, but delivers an EPA-estimated 96 MPGe combined in its RWD configuration. The Genesis GV60 Performance AWD achieves 97 MPGe combined, prioritizing sporty performance, while the Tesla Model Y Long Range offers greater range and attains 122 MPGe combined. The Audi Q4 e-tron offers a more budget-conscious option, achieving 100 MPGe combined. The Lexus RZ 450e appeals to buyers who prioritize the Lexus brand’s reputation for reliability, refinement, and ownership experience, even if other EVs on the market offer slightly superior MPGe or range figures.

Tips to maximize efficiency

Use the RZ 450e’s regenerative braking system to its full potential. By anticipating stops and allowing the vehicle to decelerate naturally, you can recapture significant energy and extend your range. Familiarize yourself with the different regenerative braking modes and find the setting that best suits your driving style.

Precondition the cabin while the vehicle is plugged in, especially during extreme temperatures. This process warms or cools the interior using grid power rather than draining the battery. Maximizing your efficiency will help get you closer to the mileage numbers for the broader Lexus brand. You can view all Lexus fuel economy data on our site.

Maintaining optimal tire pressure is important for maximizing efficiency, which can add up even in an electric vehicle. Under-inflated tires increase rolling resistance, requiring the motor to work harder and consume more energy. Check your tire pressure regularly, particularly during temperature fluctuations.

Reduce unnecessary weight. Carrying excessive cargo in the vehicle decreases efficiency. Remove any items you don’t need on a regular basis, such as sports equipment or tools, to minimize the load on the drivetrain.

Monitor your driving habits. Aggressive acceleration and hard braking consume more energy. Adopt a smoother, more gradual driving style to maximize efficiency, especially during highway driving where air resistance is a factor.
