The Ford Expedition is a full-size three-row SUV, manufactured by Ford. Introduced for the 1997 model year as the successor of the Ford Bronco, the Expedition was the first full-size Ford SUV sold with a four-door body. For its entire production life, the Ford Expedition has been derived from the corresponding generation of the Ford F-150 in production, sharing some body and mechanical components. The fourth-generation Ford Expedition began production for the 2018 model year. Similar to the configuration of the Chevrolet Tahoe and Suburban, the Ford Expedition is sold in regular and extended lengths (the Ford Expedition EL/Max); sold since 2007, the latter functionally serves as the replacement for the Ford Excursion.

Since 1997, the Lincoln division has marketed the Ford Expedition as the Lincoln Navigator, the first full-size SUV sold by a luxury auto brand in North America (the Expedition was never sold as a Mercury). The third Ford vehicle to use the Expedition nameplate, the full-size SUV follows a 1992 F-150 Eddie Bauer concept vehicle and a 1995 trim level package on the two-door Ford Explorer Sport.
The all-new full-size SUV was unveiled on May 9, 1996, and launched on October 2, 1996, as a 1997 model.[8][9] It replaced the aging two-door Ford Bronco. The XLT was the base model. The Expedition featured optional three row seating, first row captains chair seating, available second row captains chair seating, leather seating surfaces, illuminated running boards, heated side view mirrors, power moon roof, dual zone climate control and Ford's Mach audio sound system with rear subwoofer. Many of these features were standard on the Eddie Bauer version.
Expedition was available with automatic full-time ControlTrac four-wheel drive with two-speed dual range BorgWarner 4406 transfer case and a center multi-disc differential. ControlTrac was introduced in 1995 and included four selectable modes: Two High, Auto, Four High (lock) and Four Low (lock). Two High mode and Auto mode with auto-lock was not available.[10]
The 1999 model year received a facelift similar to that of the 1999 model year Ford F-150. Included in the update was a new front grille which now dropped lower in the center, grille work, as well as a new front bumper that incorporated the fog lamps into the lower valance and larger center air intake. Both the 4.6 liter and 5.4 liter V8 engines received updates including more power and torque. The two High mode for automatic full-time ControlTrac four-wheel drive equipped models was dropped, leaving only Auto, Four High (lock), and Four Low (lock) modes. The dashboard also received an updated radio and air conditioning controls and revised gauge cluster and a digital odometer for the first time.
The redesigned second-generation Expedition was developed under the U222 program code name from 1996 to 2002, under Ford chief vehicle engineer Steve von Foerster and chief program engineer John Krafcik from 1998 to 2002.[3][19] Design work began in 1997, with a proposal by Tyler Blake being chosen by management and frozen for production in 1999. UN93-body mules were spotted testing in 2000, with full prototypes running from late 2000. The new Expedition was unveiled at the 2002 North American International Auto Show, in January. It was launched in May 2002 for the 2003 model year[4] and featured a new four-wheel independent long-travel suspension system, becoming the first full-size sport utility vehicle to use a fully independent suspension.[20]
The new independent rear suspension (IRS) was perceived as being controversial by some at the time of its introduction.[21] A misconception was that the Expedition's towing and off-road capabilities would be reduced, in comparison to the previous generation's rear live axle. Nevertheless, underbody obstacle clearance improved by half an inch, and up to two inches under the axle differentials.[22] The new suspension reduces rear unsprung mass by 110 pounds (50 kg), and allows for a full 9.4 inches (240 mm) of suspension travel (how much the wheels can travel up or down) improving its ability to traverse uneven terrain for improved control and ride quality.[23][24] The four-wheel independent long-travel suspension itself is a purpose-built version of race suspensions found on off-road desert race vehicles.[25]
Towing capacity increased by 800 lb (360 kg) for a high towing capacity of 8,900 lb (4,000 kg) when properly equipped with the appropriate axle ratio and heavy-duty trailer towing package.[26] Payload capacity was increased up to 1,614 lb (732 kg). Expedition also gained a hydroformed fully boxed frame providing a 70 percent improvement in torsional stiffness. Heavy Towing versions received a heavy duty 9.75" Rear Differential and Axle combination compared to the 8.8" of the standard version.
The automatic full-time ControlTrac four-wheel drive system remained available, with an uprated two-speed dual range BorgWarner 4416 transfer case. The new transfer case featured an updated intelligent locking center multi-disc differential with front-to-rear "torque biasing" capability in Auto mode. A new dedicated microprocessor with new control software was added allowing the system to detect different terrain and surface conditions to predict traction loss before it happens. Two High mode was also reintroduced. Four-wheel electronic traction control was now available as an option, and simulated front and rear differential locks.[25]
The new four-speed automatic transmission, now called 4R75E, featured fully electronic Smart Shift technology. A turbine speed sensor improved transmission control and provided the basis for the fully electronic shift scheduling. The transmission's microprocessor speeds were improved for better responsiveness and precision of the control system. The transmission was continuously learning, and would calculate the torque in the next gear and schedule shift points based on the Expedition's projected performance in the next gear.[32] For 2005 model Expeditions the 4R75E transmission is designated by the letter "B" on the manufacturers safety compliance certification label, located in the driver's-side doorjamb. For 2006 model Expeditions, the 4R75E transmission is designated by the letter "Q".
The high-strength hydroformed fully boxed Ford T platform (chassis) was a modified version of the half-ton platform from the Ford F-150. The new T1 platform replaced the one dating to the original model, and provides 10 percent more torsional rigidity. T1 incorporates a four-wheel independent long-travel suspension system (first introduced on the second generation) with redesigned suspension geometry and an all-new five-link rear suspension with new rear lower control-arms. As with previous model years, the suspension system could be had with adaptive pneumatic air-ride springs.
Selectable automatic full-time Control Trac four-wheel drive continues to be offered, and uses a two-speed dual range BorgWarner 4417 transfer case with intelligent locking center multi-disc differential and "torque biasing" capability. Four-wheel electronic traction control is standard and off-road underbody skid plate armor is optional. A new default off-road program with throttle response recalibration was added, and is automatically activated when Four Low (lock) mode is selected. Expedition can achieve an off-road crawl ratio of 41.06:1 with a low range ratio of 2.64:1 and rear axle ratio of 3.73:1.
The selectable automatic full-time ControlTrac four-wheel drive system continues to be offered, but gains a trio of new off-road electronic systems in the form of Hill Ascent Assist (HAA), Hill Descent Control (HDC), and Ford Truck Apps (FTA). FTA gives off-road orientation/geometry, 4x4 system status, and traction control system status in real-time. The four-wheel electronic traction control system (brake differential locking control) was recalibrated to take into account the new EcoBoost V6's higher torque output and earlier torque delivery.
The heavyweight 6,155-pound (2,792 kg) as tested, 2015 Expedition Platinum with 3.5 liter EcoBoost V6 and selectable automatic full-time ControlTrac four-wheel drive was clocked from 0 to 60 mph (0 to 97 km/h) in 6.4 seconds. The full-size SUV can clip 100 mph (160 km/h) in 18.2 seconds, 110 mph (180 km/h) in 24.3 seconds, and is electronically safety-limited to 113 mph (182 km/h). Expedition has a near perfect 50:50 front:rear balanced weight distribution and center of gravity positioned at 28.5 inches.[58]
Expedition Platinum averaged 39.2 mph (63.1 km/h) in a 610-foot (190 m) slalom run and pulled 0.78g in roadholding skidpad testing. High speed emergency braking from 70 to 0 mph (113 to 0 km/h) was completed in 170 feet (57 yd; 52 m). In comparison, the Expedition's main rival took a full 10 feet (3.3 yd; 3.0 m) longer, completing the same emergency brake test in 180 feet (60 yd; 55 m).[58]
The Expedition is 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 is available to augment the 4x4 system. Both the center and rear locking systems are teamed with four-wheel electronic traction control (ETC), which simulates a locking front differential by ABS "brake locking" the front differential. The Expedition's off-road electronic aids Hill Descent Control (HDC) and Hill Ascent Assist (HAA) are joined by the Terrain Management System adapted from the Ford Raptor. Terrain Management is capable of working with 4L mode, like the Ford Raptor, and has seven drive modes to choose from which include Normal, Eco, Sport, Tow/Haul, Gravel/Snow, Mud/Ruts, and Sand. The four-wheel drive system has three direct drive modes which include 2H, 4A, and 4L. The 4H mode has been dropped from the selection, as the Terrain Management computer now controls the electronic center lock of the four-wheel drive system. Terrain Management engages the electronic center lock for a 50:50 front:rear torque split while in 4A direct drive mode, when the Mud/Ruts or Sand modes are selected. The 4L direct drive mode engages the electronic center lock regardless of the off-road drive mode selected. A "tap to lock/unlock" button is located near the drive mode dial for operation of the electronic rear lock.[68] 2ff7e9595c
