The Lincoln Navigator is a full-size luxury SUV with room for well-heeled families and the muscle to haul their toys. Significantly refreshed last year, the Navigator received much-needed interior and exterior updates, plus a new turbocharged V6 engine that does more with less. The Navigator can tow up to 9,000 pounds and is available in two lengths. While its technology improves this year with the easier-to-use Sync 3 infotainment system, the Navigator still lags competitors such as the Cadillac Escalade and Mercedes-Benz GL in other key technology and safety aspects. Unlike the Navigator, those rivals boast automatic emergency braking, lane-departure warning, radar-based cruise control, and even have the capability to massage the front-seat occupants.
