The XM’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 XM 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 XM has a standard PostCrash iBrake, 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 XM has a standard Active Park Distance Control 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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the XM. But it costs extra on the Macan Electric.
Both the XM and the Macan Electric have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, rear cross-path warning and driver alert monitors.
The BMW XM weighs 698 to 1090 pounds more than the Porsche Macan Electric. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
