The X4 M’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Kona N doesn’t offer pre-crash pretensioners.
The BMW X4 M 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 Kona N doesn’t offer knee airbags.
The X4 M has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Kona N doesn’t offer a whiplash protection system.
The X4 M 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 Kona N 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 X4 M offers an optional 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 Kona N doesn’t offer automatic braking for stationary objects directly to the rear.
The X4 M has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Kona N doesn’t offer all-wheel drive.
The X4 M offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Kona N only offers a rear monitor.
Both the X4 M and the Kona N have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, 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 X4 M weighs 1257 pounds more than the Hyundai Kona N. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
