Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The EQE Sedan has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The EC40 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the EQE Sedan and the EC40 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, front seat center airbag, 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, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
The Mercedes EQE Sedan weighs 565 to 764 pounds more than the Volvo EC40. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
