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 Ultra 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.
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 XC40 are reminded to check the back seat if they opened the rear door before starting out. The Hornet doesn’t offer a back seat reminder.
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 Hornet have rear cross-traffic warning, but the XC40 has Braking Intervention (automatically applies the brakes) to better prevent a collision when backing near traffic. The Hornet’s Rear Cross Traffic Alert doesn’t automatically brake.
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, plastic fuel tanks, 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 available around view monitors.
