The 2017 Lincoln Navigator is a full-size luxury SUV that's available in two sizes: the standard-wheelbase and the extended-wheelbase Navigator L. Both lengths have three-row seating, with captain's chairs in both the first and second row. This places the Navigator's standard seating capacity at seven passengers, but an available three-person 40/20/40 split second-row bench seat increases seating capacity to eight.

The 2017 Lincoln Navigator is a quiet, smooth and pleasant SUV to drive on the highway. Its turbocharged V6 provides plenty of power for swift acceleration, towing and maintaining speed on long uphill grades. We also like the way it goes around turns. Though undeniably heavy, it certainly feels more nimble than the Cadillac Escalade, and its independent rear suspension and optional adaptive suspension dampers combine for an excellent ride on the open road. Get the Navigator off the highway, though, and its appeal dims. There's just no getting around its massive size, which makes it a handful to maneuver and park in crowded cities.

From a strictly viewed-not-touched perspective, the 2017 Lincoln Navigator is welcoming and classy. Even the seats and high-quality leather upholstery continue the narrative that the Lincoln is a truly luxurious vehicle. Unfortunately, there are multiple hard, low-quality plastics that you come in contact with quite a bit in the cabin. Many of the knobs, trim pieces and instrument stalks feel like they've come right out of the Navigator's less-expensive sibling, the Ford Expedition. Depending on your expectations that can detract from the luxury experience a bit.

The center console, with Sync 3 front and center, offers a clean, logical layout for navigation, audio, phone and climate controls. There is a learning curve with Sync, but the new system is designed similarly to a smartphone, using gestures such as pinch-to-zoom or swipes. Once you connect your phone it can access your weather, music and other integrated smartphone apps. Unfortunately, Lincoln doesn't offer integrated systems in the Navigator such as Apple CarPlay or Android Auto yet.

When it comes to sheer size and how it translates to interior space, the Navigator is almost unrivaled. Passengers in the standard first- and second-row captain's chairs enjoy comfortable accommodations with plenty of room to stretch out. Even in the standard-wheelbase version, the third row feels remarkably spacious. The captain's chairs in the second row and abundant headroom help with the awkward climb to the third row. And then there's the cargo space.

Easing cargo-loading chores is the standard power-folding third-row seat that folds flat into the floor with the touch of a button, and returns upright just as effortlessly. Behind the third row in the standard-length Navigator, there is 18.1 cubic feet of space. Fold the second and third row down and suddenly that figure bulges to 103 cubes. The extended Navigator L has more than 42 cubic feet of cargo space behind the third row and an expansive 128 cubic feet when you fold the second and third row. The closest competitor is the Escalade ESV, with its 120 cubes of cargo.
