The 2024 Lexus RZ 300e, with its 18-inch wheels, gets a combined fuel economy rating of 125 MPGe. This rating makes the RZ 300e an efficient electric vehicle, a good option for buyers who want luxury, quiet operation, and lower fuel costs for an EV. If you want the Lexus experience without using gasoline, consider this vehicle.

City and highway performance

The EPA rates the RZ 300e at 137 MPGe in the city and 112 MPGe on the highway. This difference shows the RZ 300e’s advantage in stop-and-go traffic, where regenerative braking captures energy. City drivers will appreciate the higher city MPGe; the RZ 300e works well in that environment. The RZ 300e remains efficient on the open highway, but its range is affected by higher speeds and less regenerative braking. Suburban drivers will find the highway numbers valuable.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Lexus RZ 300e at $600. This is based on driving 15,000 miles per year and using national average electricity prices. This low annual fuel cost is a major benefit. Compared to a gasoline-powered luxury SUV, the savings can be significant, freeing up money for other things.

Real-world expectations

The EPA provides ratings, but real-world MPGe can change based on driving, weather, terrain, and accessories like air conditioning. Aggressive acceleration and high speeds reduce efficiency, while gentle driving and good temperatures improve it. Battery performance can decrease in extreme cold, slightly lowering range in winter. However, the RZ 300e’s efficient powertrain and energy management systems help minimize these issues, delivering good fuel economy.

How it compares

The RZ 300e’s efficiency compares well against other luxury electric SUVs. For example, the Genesis GV60 Performance gets a combined 97 MPGe, making the Lexus more efficient. The Jaguar I-PACE is rated at 76 MPGe combined, further showing the RZ 300e’s advantage. The RZ 300e excels even against plug-in hybrid competitors when running only on electric power, often exceeding their electric-only range and MPGe. Lexus buyers often compare similar vehicles, and the RZ 300e’s efficiency is a key difference. See RZ MPG across all years.

Tips to maximize efficiency

Use regenerative braking. The RZ 300e uses a regenerative braking system that converts kinetic energy into electricity, recovering energy during deceleration. Adjust the level of regenerative braking with the steering wheel paddles to maximize energy capture in stop-and-go traffic. This will extend your range and reduce wear on your brakes.

Precondition the cabin while plugged in. Heating or cooling the interior while the vehicle is plugged in reduces battery drain when driving. This helps maintain range and efficiency, particularly in extreme temperatures.

Watch your driving. Smooth acceleration and consistent speeds maximize efficiency in any electric vehicle, including the RZ 300e. Avoid hard acceleration and braking, which use more energy. Monitor the energy consumption display and adjust your driving.

Keep tires inflated. Properly inflated tires reduce rolling resistance, improving efficiency. Check your tire pressure regularly and maintain the recommended level on the tire placard. This can improve the RZ 300e’s range.

Use ECO mode. The RZ 300e has an ECO mode that optimizes vehicle systems for efficiency. It may slightly reduce performance but can improve range on long trips. Explore all Lexus fuel economy data.
