In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Navigator L are reminded to check the back seat if they opened the rear door before starting out. The SQ7 doesn’t offer a back seat reminder.
The Navigator L’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The SQ7 doesn’t offer a driver alert monitor.
Both the Navigator L and the SQ7 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear 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 and rear cross-path warning.
The Lincoln Navigator L weighs 733 pounds more than the Audi SQ7. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
