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 Land Rover Discovery Sport doesn’t offer pretensioners for its second-row 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 Discovery Sport doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Volvo XC40 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Land Rover Discovery Sport doesn’t offer height-adjustable seat belts.
The XC40 has a standard Whiplash Protection System (WHIPS), which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The Discovery Sport doesn’t offer a whiplash protection system.
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 Discovery Sport 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 XC40 has a standard CTA Auto Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Discovery Sport doesn’t offer automatic braking for stationary objects directly to the rear.
The XC40 offers an optional 360-Degree Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The Discovery Sport only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the XC40 and the Discovery Sport have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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.
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 Discovery Sport has not been tested, yet.
