The redesigned 2018 Expedition full-sized SUV shaves 300 pounds off its predecessor’s weight to bolster efficiency and performance, while piling on new comfort, convenience, and safety features. The updated 3.5-liter EcoBoost V6 engine adds a fuel-saving start/stop system, and it is mated to a 10-speed automatic transmission. Ford claims this will be the most powerful Expedition yet, putting output above 365 hp. The modern cabin provides seating for eight, with Ford claiming that third-row passenger room has improved. Both the second- and third-row seats can be folded flat with a button push. Available safety features will use both camera and radar technology, and they include automatic braking, lane-keep assist, active cruise control, and blind-spot monitors that can see to all the way to a trailer’s flanks. An extended-length model, dubbed MAX, is also available.
