The size and 6,200-pound curb weight of the vehicle tax the V-8 engine at times compared to other vehicles in the class. Shifting is slick and easy, though, turning low revs at highway speeds to reduce engine noise. The Navigator handles solidly and stably, but you'll never forget you're in such a big, heavy vehicle. Body roll is what you'd expect from a big, heavy SUV—and expect heavy nosedive and lots of body motion during quick stops, or any change in direction for that matter—but the four-wheel independent suspension helps provide a smooth ride.
In Navigator and longer-wheelbase Navigator L models, a 310-horsepower, 5.4-liter V-8 engine drives either two or four wheels through a six-speed automatic transmission. Hauling is second nature to the Navigator—the maximum tow rating is 9,100 pounds.
