For enhanced safety, the front and second-row seat shoulder belts of the Mercedes EQB have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Kia Niro EV doesn’t offer pretensioners for its rear seat belts.
The EQB’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Niro EV doesn’t offer pre-crash pretensioners.
The EQB offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Niro EV doesn’t offer all-wheel drive.
The EQB offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Niro EV only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the EQB and the Niro EV have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available lane departure warning systems.
The Mercedes EQB weighs 921 to 1117 pounds more than the Kia Niro EV. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
