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 Sorento Plug-In Hybrid doesn’t offer pre-crash pretensioners.
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 Sorento Plug-In Hybrid doesn’t offer a front passenger side knee airbag.
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 Sorento Plug-In Hybrid 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.
Both the XM and the Sorento Plug-In Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, around view monitors, rear cross-path warning and driver alert monitors.
The BMW XM weighs 1589 to 1592 pounds more than the Kia Sorento Plug-In Hybrid. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
