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 Toyota Sequoia 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 Sequoia doesn’t offer pre-crash pretensioners.
Both the Q7 and Sequoia have child safety locks to prevent children from opening the rear doors. The Q7 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 Sequoia’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.
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 Sequoia 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 optional Maneuver Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Sequoia doesn’t offer backup collision prevention brakes.
Full-time four-wheel drive is standard on the Q7. Full-time four-wheel drive gives added traction for safety in all conditions, not just off-road, like the only system available on the Sequoia. Four-wheel drive of any type costs extra on the Sequoia.
When descending a steep, off-road slope, the Q7’s standard Hill Descent Assist allows you to creep down safely. The Sequoia doesn’t offer Hill Descent Assist.
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 Sequoia 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 Sequoia 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 Sequoia have rear cross-traffic warning, but the Q7 has Automatic Brake Activation (automatically applies the brakes) to better prevent a collision when backing near traffic. The Sequoia’s Rear Cross Traffic Alert doesn’t automatically brake.
For better protection of the passenger compartment, the Q7 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Sequoia uses a body-on-frame design, which has no frame members above the floor of the vehicle.
Both the Q7 and the Sequoia have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, 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 and rear cross-path warning.
Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Q7 is 2.8% less likely to roll over than the Sequoia.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Q7 its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 44 vehicles tested by the IIHS. The Sequoia has not been tested, yet.
