95 MPG combined marks the 2024 Lexus RZ 450e AWD with 20-inch wheels as a dedicated electric vehicle, a choice for buyers who prioritize luxury, technology, and lower fuel costs, accepting some range limitations as part of EV ownership. This isn’t a vehicle for long road trips but for suburban drivers seeking a stylish and quiet daily ride.

City and highway performance

The EPA estimates the RZ 450e gets 102 MPG in the city and 87 MPG on the highway. This difference is typical for an electric vehicle. EVs shine in stop-and-go city driving; regenerative braking reclaims energy that would otherwise be lost in a conventional car. Highway driving requires constant power to overcome air resistance, which strains the battery and reduces efficiency. These numbers show the RZ’s intended market: short to medium commutes and errands, where its electric powertrain performs best.

Annual Fuel Cost

The EPA calculates the annual fuel cost for the 2024 Lexus RZ 450e AWD (20-inch wheels) at $800. This is based on 15,000 miles driven per year and the national average electricity price. Electricity prices vary, so this estimate may not be perfect for everyone. Charging at home, especially with off-peak rates, can greatly reduce this cost, making the RZ even more appealing. This cost of $800 is substantially lower than what owners of gasoline powered Lexus SUVs would have to spend each year.

Real-World Expectations

EPA numbers are a standard, but real-world conditions will affect the RZ 450e’s efficiency. Ambient temperature (cold reduces range), driving style (hard acceleration uses more energy), and accessories like AC and heat all matter. Expect slightly lower numbers than the EPA estimates, especially in extreme weather. Many owners easily meet or exceed EPA estimates however. A benefit of electric vehicles is that consistent good driving will result in range and efficiency improvements.

How It Compares

The RZ 450e competes with other luxury electric SUVs like the Genesis GV60, Cadillac LYRIQ, and Tesla Model Y. The GV60 Performance AWD is rated at 97 MPGe combined. The LYRIQ RWD gets 105 MPGe combined and the Model Y Long Range achieves 122 MPGe combined. Models such as the Tesla Model X are available, but they are often more expensive or larger. These comparisons show the RZ’s place in the EV market: it favors luxury and refinement over pure efficiency. Buyers must consider these trade-offs and what they value most. Those who want to see all Lexus fuel economy data might be interested in how Lexus’s gasoline and hybrid options compare to the fully electric RZ. Or perhaps they want to see the RZ MPG across all years.

Tips to Maximize Efficiency

Take advantage of regenerative braking. The RZ 450e offers different levels of regenerative braking, letting you control how the car slows down when you lift off the accelerator. Maximize regeneration in city driving and anticipate stops to recapture energy and extend range. Learn to modulate the accelerator pedal for smooth, consistent power delivery.

Precondition the battery and cabin temperature before unplugging each morning. Use the Lexus app to preheat or precool the vehicle while it’s still connected to the charger. This draws power from the grid, saving battery range for your drive. Preconditioning while plugged in uses less energy to reach the desired temperature.

Minimize aerodynamic drag. Remove unnecessary items from the roof rack and ensure tires are properly inflated. This is especially important during highway driving, where drag affects energy consumption more. It’s easy to improve efficiency by doing these things.

Drive in Eco mode when suitable. The RZ 450e offers an Eco mode that reduces throttle response and limits power consumption. Use it during low-demand situations, such as highway cruising or gentle city driving, to maximize efficiency. It might not be the most exciting driving experience, but it will help extend your range.
