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 Purosangue 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 Purosangue doesn’t offer a back seat reminder.
The BMW XM has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Purosangue doesn’t offer knee airbags.
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 Purosangue 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 Purosangue doesn’t offer backup collision prevention brakes.
Both the XM and Purosangue have rear cross-traffic warning, but the XM has Cross Traffic Warning with braking function (automatically applies the brakes) to better prevent a collision when backing near traffic. The Purosangue’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the XM and the Purosangue have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, 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 1241 to 1244 pounds more than the Ferrari Purosangue. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
