Power for both 2010 Lincoln Navigator models comes from a 300-horsepower, 5.4-liter V-8 engine that drives either two or four wheels through a six-speed automatic transmission. Hauling is second nature to the Navigator, with a maximum tow rating of 9,100 pounds.
Handling is solid and stable, though it's a large SUV, not a sports car. The size and 6,200-pound curb weight of the vehicle also tax the 5.4-liter 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. Body roll is what you'd expect from a big, heavy SUV, but four-wheel independent suspension helps provide a smooth ride.
As AutoWeek tells it, the Navigator is a "surprisingly agile handler." Cars.com finds the ride "pleasant...but nothing spectacular." Size does have its advantages, however, with ConsumerGuide noting the way the Navigator's "sheer size and weight tame most surface imperfections."
A weaker-than-expected V-8 engine dampens the party a bit, however. Edmunds calls Lincoln to the carpet, saying the 2010 Navigator "lacks the standout performance expected" of luxury SUVs these days, especially in comparison to offerings from Cadillac, Infiniti, and Mercedes-Benz. Cars.com agrees, noting that the engine is "woefully lacking in the power department."
Making up for this lack of power is a very smooth and well-tuned six-speed automatic transmission. Cars.com points out that with this single transmission, the Lincoln Navigator can be equipped to tow "up to 8,950 pounds."
Both two- and four-wheel-drive variants are available. Fuel economy pays the price you'd expect of a big V-8 engine and 6,200-pound curb weight. ConsumerGuide's tests show an average of "12.5 mpg, low even for this class." EPA ratings are only available for the two-wheel-drive model, which rates 14 mpg city and 20 mpg highway for an expected combined average of 16 mpg.
