For enhanced safety, the front and second-row seat shoulder belts of the Audi Q7 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 Q7’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 Audi Q7 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 Q7 has a standard Secondary Collision Brake Assist, which automatically applies 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 Q7 offers an optional backup collision prevention system 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.
A passive infrared night vision system optional on the Q7 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The Discovery Sport doesn’t offer a night vision system.
The Q7 offers an optional Top View Cameras 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 Q7 and the Discovery Sport have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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 and rear cross-path warning.
The Audi Q7 weighs 504 to 977 pounds more than the Land Rover Discovery Sport. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
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 Q7 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.
