There's almost no choice with respect to powertrains. All Expedition models come with a 5.4-liter flex-fuel V-8 that makes 310 horsepower and 365 pound-feet of torque. This is matched to a six-speed automatic transmission that is responsive and smooth, driving either the rear wheels or all four wheels depending on the model.
Despite its size, driving the Expedition is relatively easy—thanks to light but precise steering, and a suspension that does a great job reeling all that weight in. The net product is a mammoth SUV that doesn't always feel mammoth from behind the wheel. The only major criticism, other than the lack of engine power, is the Expedition's rather spongy brake feel and plentiful nosedive in hard stops.
