The Highlander Limited's optional 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 Toyota Highlander 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 Highlander has standard Whiplash Injury Lessening Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Discovery Sport doesn't offer a whiplash protection system.
To help make backing safer, the Highlander Limited/Platinum's cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Discovery Sport doesn't offer a cross-path warning system.
Both the Highlander and the Discovery Sport have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear parking sensors.
For its top level performance in the IIHS moderate overlap frontal impact, side impact, rear impact, roof-crush crash tests, an “Acceptable” rating in the newer small overlap frontal crash test, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Highlander its highest rating: “Top Pick Plus” for 2015, a rating granted to only 64 vehicles tested by the IIHS. The Discovery Sport has not been tested, yet.
