For enhanced safety, the front and rear seat shoulder belts of the Volvo XC40 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Dodge Hornet doesn’t offer pretensioners for its rear seat belts.
The XC40’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Hornet doesn’t offer pre-crash pretensioners.
Both the XC40 and Hornet have child safety locks to prevent children from opening the rear doors. The XC40 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Hornet’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The XC40 has standard Post-impact braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Hornet 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 XC40 and the Hornet have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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, rear cross-path warning and available around view monitors.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the XC40 the rating of “Top Safety Pick” for 2017, a rating granted to only 235 vehicles tested by the IIHS. The Hornet has not been tested, yet.
