The EQS SUV’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Macan Electric doesn’t offer pre-crash pretensioners.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the EQS SUV are reminded to check the back seat if they opened the rear door before starting out. The Macan Electric doesn’t offer a back seat reminder.
The EQS SUV’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Macan Electric doesn’t offer a whiplash protection system.
The EQS SUV has a standard Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Macan Electric doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The EQS SUV has a standard Maneuvering Brake Function that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Macan Electric doesn’t offer automatic braking for stationary objects directly to the rear.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The EQS SUV has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Macan Electric doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
The EQS SUV’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Macan Electric doesn’t offer a driver alert monitor.
Both the EQS SUV and the Macan Electric 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, rearview cameras and rear cross-path warning.
The Mercedes EQS SUV weighs 670 to 1080 pounds more than the Porsche Macan Electric. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
