The EQE SUV’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The RZ doesn’t offer pre-crash pretensioners.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The EQE SUV has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The RZ doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the EQE SUV and the RZ have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
The Mercedes EQE SUV weighs 681 to 1491 pounds more than the Lexus RZ. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
