The Ford Expedition receives a mild refresh for 2015 that includes LED fog lights and a revised rear hatch on the outside and an updated center stack with an optional 8-inch screen on the inside. The biggest news is a new 3.5-liter EcoBoost twin-turbo V6 engine mated to a 6-speed automatic replacing the old V8 drivetrain. A new Platinum trim marks the top-of-the-line.
