Compare the2026 Porsche Cayenne CoupeVS 2026 Audi SQ8

The Porsche Cayenne Coupe has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The SQ8 doesn’t offer knee airbags.

Both the Cayenne Coupe and the SQ8 have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning, driver alert monitors and available night vision systems.
