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 Automatic Braking After Collision, 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 use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Discovery Sport doesn’t offer backup collision prevention brakes.
The XC40 has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Discovery Sport’s blind spot costs extra.
To help make backing out of a parking space safer, the XC40 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the Discovery Sport.
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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors and available around view monitors.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the XC40 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 87 vehicles tested by the IIHS. The Discovery Sport has not been tested, yet.
