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. The front cabin is roomy, but the standard seats are uncomfortable, and the push-button gear selector is fussy to use. Rear passengers are pampered with heated seats, a variety of connectivity features, and a hospitable third-row seat. Rear-wheel drive is standard, with four-wheel drive optional.
