What size battery is in the Lexus RZ 450?
The Lexus RZ 450e uses a 71.4 kWh gross battery pack, with roughly 64 kWh of usable energy for real-world driving.
That battery size shapes the SUV’s EPA rating, charging behavior, and daily practicality in a compact luxury EV package built on Toyota’s e-TNGA platform.
Battery capacity and chemistry
Battery chemistry and packaging
The RZ 450e relies on a lithium-ion battery pack integrated into Lexus’s adaptation of Toyota’s e-TNGA architecture. Lexus typically describes the pack as a high-energy, thermally managed unit designed to balance performance, range, and durability, but it does not frequently publish an exhaustive breakdown of the exact cell chemistry in public specifications beyond “lithium-ion.”
Key figures you should know about the RZ 450e's battery and build are outlined here.
- Gross battery capacity: 71.4 kWh
- Estimated usable capacity: about 64 kWh
In practical terms, roughly two-thirds of the battery's energy is available for driving between charges, depending on temperature and driving style.
Range and charging implications
How size translates to everyday use
Understanding the battery size helps explain the vehicle’s range and charging performance in normal driving conditions.
EPA-range and charging considerations in context of the RZ 450e:
- EPA-estimated range (all-wheel drive): about 196 miles per charge
- DC fast charging capability: supports rapid charging on compatible public chargers (peak rates vary by market and charging conditions)
Real-world range varies with climate control use, outside temperature, terrain, and driving style, while charging speeds depend on the charger and the battery’s temperature at the start of charging.
What this means for buyers
Understanding the battery size helps buyers estimate daily usability, cost per mile, and charging plans for commuting and trips.
Summary: The RZ 450e’s 71.4 kWh gross pack, with around 64 kWh usable, aligns with its EPA rating and typical charging expectations for a luxury electric SUV in its class.
Summary: The Lexus RZ 450e is equipped with a 71.4 kWh gross lithium-ion battery, offering roughly 64 kWh of usable energy. This sizing supports an EPA-rated 196-mile range (AWD) and enables DC fast charging on compatible networks, balancing luxury, practicality, and efficiency in Lexus’s first dedicated EV.

What kind of battery is in the Lexus RZ?
lithium-ion battery pack
Every RZ now comes with a 77-kwh lithium-ion battery pack instead of the 71.4-kwh pack on the current 2025 Lexus RZ. More cells result in higher output with the revised front motor throughout the lineup, and water cooling for the battery and motor system also enables more sustained performance.
What is the battery life of the Lexus RZ 450e?
The 63.4-kWh battery pack delivers an EPA-estimated range of 220 miles with a full charge. With a DC fast charger, the RZ 450e needs about 30 minutes to fill from 20% to 80%. With a Level 2 home charger, it takes about 9.5 hours to fill the battery.
What is the battery capacity of the RZ?
The Lexus RZ has different battery capacities depending on the model: the RZ 300e has a 72.8 kWh battery, while the RZ 450e has a 71.4 kWh battery. For the 2026 model year, Lexus is introducing a larger 77 kWh battery pack to the entire RZ lineup for enhanced performance, including the RZ 350e and RZ 450e models, as well as a new performance trim with the same pack.
