Let's consider a basic law in automotive physics: A vehicle weighing some 6,000 pounds will rarely provide the same driving dynamic of a vehicle weighing 4,000 pounds. Most variants of...
... the 2013 Ford Expedition and Expedition EL start out weighing almost three tons – when loaded with passengers and cargo they will weigh much more. To that end, anticipate the additional mass when steering, accelerating or braking. Thankfully, Ford's engineers have done their best to disguise the Expedition's heft without actually reducing or eliminating it. The big Ford's center of gravity is lowered with the incorporation of an all-independent suspension, while the SUV's 5.4-liter V8 supplies sufficient torque (365 lb-ft) to adequately move that mass. Directional control is provided by power-assisted rack-and-pinion steering, while stopping is accomplished via 4-wheel anti-lock disc brakes.
Notably, if opting for 4-wheel drive, the Expedition's approach and breakover angles are slightly diminished, whereas the long-wheelbase Expedition EL's are (incrementally) enhanced. Be careful out there.
