While the Navigator hasn't been crash-tested by the Insurance Institute for Highway Safety (IIHS), the National Highway Traffic Safety Administration (NHTSA) gives it four out of five stars for overall safety.
All Navigators, both standard and extended-wheelbase, with rear-wheel-drive or 4WD, get four stars for frontal crash and five stars for side crash from the NHTSA. But the 4WD models get four stars for rollover safety, while the rear-wheel-drive versions get only three out of five stars on the same test.
The 2014 Navigator includes the usual assortment of dual front, side and curtain airbags, along with anti-lock brakes, traction, and stability control with roll mitigation. There's also trailer-sway control, which helps the vehicle correct for the swinging motion induced when it's towing. And the luxury SUV's substantial size and short list of driving aides should make it a relatively safe option for both driver and passengers.
Some drivers might find outward visibility challenging in the Navigator because of its sheer height, but thankfully the big Lincoln comes with front parking sensors and a rearview camera system. And in case you have teens in the house or want valets to take it easy, Ford's MyKey system can limit things like top speed and audio volume when you're not in the vehicle.
