The fourth-generation Expedition, known internally at Ford Motor Company as the "U553", was unveiled on February 7, 2017 at the Dallas Cowboys training facility, Ford Center in Frisco, Texas, ahead of its Chicago Auto Show debut.
Production of the new Expedition started on September 25, 2017.
The vehicles arrived at dealerships in November 2017.

The all-new Expedition was developed in secret under the U553 program codename and features body-on-frame (BOF) architecture with high-strength lightweight material construction consisting of boron steel and aluminium.
The four-door body is constructed from alumimium-alloy, while the frame is constructed from boron steel.
The U553 will move to the all-new half-ton hydroformed T3 platform (chassis), which is a modified version of the half-ton platform underpinning the P552 2015 Ford F-150.
The T3 platform will use a new four-wheel independent suspension system design.
Updated powertrain systems (engines and transmissions) including a Hybrid variant with proprietary parallel hybrid electric-drive system to help increase fuel efficiency are expected.
Expedition will gain Ford's new 10-speed 10R80 SelectShift automatic transmission which will feature artificially intelligent shifting, electronic range select, manual shift mode, and be controlled via a rotary dial on the center console.
The next-generation Expedition's chief engineer is Jackie Marshall DiMarco, who is also the chief engineer for the next-generation F-150 pickup.

Spy photographers captured early, engineering test mules of the U553 in late 2015, which sported a crude highly modified non-production intent F-150 SuperCrew body atop the production intent T3 platform chassis.
In late 2016, spy photographers managed to capture photos of the actual first pre-production prototypes of the U553, wearing the production intent body on the production intent platform.
The styling and appearance of the U553 Expedition is inspired by the U502 Explorer along with elements of the P552 F-150, the vehicle on which the new Expedition is based, and will have a more aerodynamic and streamlined silhouette, with raked windshield and sloped roofline which will lead to a rear liftgate spoiler.
The U553 Expedition's C-pillar will be more forward slanted, echoing the forward slanted C-pillar of the U502 Explorer introduced for 2011.
In addition the Expedition's body will feature sculpted sides with character lines, similar to the U502 Explorer, as opposed to the straight slab sides of the current Expedition.
Expedition's front grill and headlamp design is inspired by the facelifted P552 F-150, with the front bumper retaining a similar design and appearance to its predecessor, the U324 Expedition, after its facelift.
It also expanded the standard size version's wheelbase by 3 inches and its length by 4 inches while decreasing the height by one inch (losing 300 pounds in the process) in order to allow more leg room and space.

Expedition (U553) will be one of the very first vehicles in North America to use a new next-generation high speed Controller Area Network 3 (CAN-3) vehicle data bus system.
The CAN-3 electrical architecture is akin to a human nervous system and allows the Expedition's various on-board microprocessors and electronic vehicle control systems to communicate or "talk" to one another through electronic data that is sent and received.
With high speed CAN-3, Expedition can learn and react faster than before.

The Expedition will be available with selectable automatic full-time four-wheel drive that routes torque through a two-speed dual range transfer case with electronic locking center multi-disc differential.
A new electronic locking rear differential will be available to augment the 4x4 system.
Both the center and rear locking systems will be teamed with four-wheel electronic traction control (ETC), which simulates a locking front differential by ABS "brake locking" the front differential.
Expedition's off-road electronic aids Hill Descent Control (HDC) and Hill Ascent Assist (HAA) will be joined by the Terrain Management System adap
