Lincoln Navigator

Redesigned for 2018, the Navigator ups the ante over its Ford Expedition sibling, with more luxury and showmanship. The cabin is quiet, elegant-looking, and full of high-tech features. There is a bit of rocking feeling at low speeds, but the ride improves and is more comfortable on the highway. Handling, however, is cumbersome, even for a large SUV. The twin-turbo V6 generates 411 hp on regular fuel, and is paired with a 10-speed automatic transmission. This combination easily moves the Navigator down the road and is capable of towing 8,300 pounds.

A freshening in the 2015 Navigator brought a turbocharged six-cylinder in place of the V8. However, fuel economy increased by only two mpg. Unfortunately, the update didn't include advanced crash-avoidance systems such as forward-collision warning. In this upscale class, such equipment should be readily available, if not a standard feature. The top-shelf Reserve adds 22-inch wheels, Lincoln Drive Control adjustable suspension, and upgraded interior leather and wood. The Navigator's cabin is spacious with room for eight and a third row that's usable even for adults.
