The lane-hogging 2015 Ford Expedition and the even-longer Expedition EL provide room for eight adults and acres of cargo space. The 3.5-liter twin-turbo V-6 makes 365 hp; a six-speed automatic with rear-wheel drive is standard and four-wheel drive is optional. Some may scoff at a V-6 in a rig of this size, but its 9200-lb towing capacity (when properly equipped) should silence naysayers. Also, its independent rear suspension soaks up bumps better than its competition and frees up more cargo space.
