The front of the RZ’s cabin is equipped with an alternative system to conventional convection heating. Radiant heat warms occupants faster and reduces energy consumption
Life on board the Lexus RZ is better thanks to design details and technical innovations that increase comfort and functionality. Radiant heating is a good example of this.
The new RZ, Lexus’ first battery-electric model on a dedicated EV platform, is also the first Lexus to incorporate this heating method.
Unlike traditional convection heating systems, which heat the air, the new RZ features two panels in the front of the cabin that use infrared radiation to heat only the solid objects around it. Thus, the driver and front passenger warm up more quickly than with conventional climate control systems.
In addition, it consumes around 8% less energy by directing heat only where it is needed, reducing the load on the climate control system and helping to maximize the vehicle’s range.
This heartwarming innovation is also a good example of how Lexus designers keep the Omotenashithe Japanese spirit of hospitality.
In this context, hospitality refers to giving RZ front-seat occupants a comfortable feeling, especially on cold days, similar to throwing a blanket over their laps.
This is achieved by concealing the two radiant heaters at knee level, in the lower part of the dashboard and the steering column. In case the driver or passenger physically touches the panel, its temperature is automatically reduced to 43°C, to prevent them from getting burned.
The RZ’s radiant heating complements the conventional cabin climate control (whose use can be limited when radiant heat is generated), and is also added to the heated seats and steering wheel.
The system is integrated into Lexus Climate Assistant, the multi-zone climate control system that automatically adjusts the cabin, seat and steering wheel heating, as well as the air conditioning, to ensure optimal thermal comfort for all occupants at all times.
Radiant heating is offered as an option on the Executive trim of the RZ, and is standard on the Luxury trim.
