2018 Lincoln Navigator IV Dimensions, Size & Specs

The Lincoln Navigator IV is 2029 mm (79.8 inches) wide with mirrors folded, and 2383 mm (93.8 inches) wide with mirrors opened. This significant increase in width when mirrors are extended affects the space needed when driving through narrow lanes or parking in tight spots. Folding the mirrors reduces the width to a more manageable size, allowing for easier garage entry and parking in narrow spaces. It’s important for drivers to be aware of this difference to avoid mirror damage or collisions in confined areas.

The curb weight of the 2018 Lincoln Navigator IV ranges from 2579 kg to 2656 kg (5687 to 5857 pounds). This substantial weight is typical for a large luxury SUV packed with extensive features and a powerful drivetrain. While the substantial mass contributes to a stable, smooth ride and enhances safety, it can also impact fuel efficiency, typically resulting in lower miles per gallon compared to smaller or lighter vehicles. Additionally, heavier vehicles may have slightly reduced agility, especially in tight cornering or quick maneuvers, but the Navigator's suspension is tuned to balance comfort with responsive handling.

With all rear seats in use, the 2018 Lincoln Navigator IV offers a luggage capacity of 547 liters (19.3 cubic feet), which is ample for several suitcases or groceries. When the rear seats are folded down, the cargo volume expands dramatically to 2925 liters (103.3 cubic feet), providing extensive space for larger loads such as furniture, sports equipment, or long trips requiring bulky gear. This high versatility makes the Navigator ideal for families and individuals needing a large, adaptable cargo area.

The Lincoln Navigator IV features a ground clearance ranging from 244 to 246 mm (9.6 to 9.7 inches). This relatively high ride height is sufficient to clear most common road obstacles and rough terrain, enhancing light off-road capability and reducing the risk of underbody damage. For passengers, the elevated seating position provides excellent road visibility, though it may require a step or running board for easier ingress and egress, particularly for shorter or elderly passengers.

Fitting the 2018 Lincoln Navigator IV into a standard residential garage can be challenging due to its large dimensions, especially its length of 5334 mm (209.8 inches) and width of up to 2383 mm (93.8 inches) with mirrors open. Most standard garages are approximately 5500 mm (18 feet) deep and around 2400 to 2700 mm (8 to 9 feet) wide. While the Navigator may physically fit in depth, the width with mirrors extended is close to or exceeds many garage widths, requiring mirrors to be folded to fit comfortably. Proper measurement of the garage and careful maneuvering are essential.

Compared to the Navigator III, the Navigator IV is slightly larger, enhancing passenger comfort and cargo space. The IV generation increased in length and width to 5334 mm (209.8 inches) and 2029 mm (79.8 inches) respectively, whereas the previous generation was slightly shorter and narrower. The increase in size improved interior volume and road presence but also meant a higher curb weight, between 2579 and 2656 kg compared to the roughly 2500-2600 kg range of the III generation, reflecting added technology and luxury features.

The 2018 Lincoln Navigator IV offers two main rim size options: 20-inch and 22-inch wheels. Corresponding tire sizes include 275/55 R20 for the 20-inch rims and 285/45 R22 for the 22-inch rims. These large wheels contribute to the vehicle’s upscale look and help deliver improved ride quality and road grip. Larger rims are typically paired with lower-profile tires, which may enhance handling precision at the expense of slight ride comfort.

The 2018 Lincoln Navigator IV competes directly with other full-size luxury SUVs like the Cadillac Escalade, Lexus LX, and Mercedes-Benz GLS. Its length of 5334 mm (209.8 inches) and sizable cargo capacity, especially with rear seats folded (2925 liters/103.3 cubic feet), place it among the largest in its class. Compared to competitors, the Navigator typically offers a combination of spaciousness, strong towing capability, and refined luxury. Its ground clearance and ride characteristics balance comfort and some light off-road utility, while its interior technology and features are designed to match or exceed benchmarks set by rival models.

The Lincoln Navigator IV's weight of up to 2656 kg (5857 lbs) and substantial size present certain challenges in daily urban driving. Maneuvering through tight city streets, heavy traffic, and parking lots requires extra care due to its bulk and wide mirror span of up to 2383 mm (93.8 inches). Parking solutions might require the use of folding mirrors and potentially larger parking spaces. The vehicle's height and large front overhang also mean clearance in low-ceiling garages or tight parking structures needs to be considered. Despite these challenges, advanced parking assist and camera systems in the Navigator help mitigate difficulties in urban environments.
