The E63 AMG S-Model, available as both sedan and wagon, has 27 more horsepower and 59 pound-feet more torque than the base E63 AMG, which only comes as a sedan in the United States.
Both autos share the same unfortunate battery protrusion in the trunk area, and while it's less of an issue in the Fusion sedan than the wagon-like C-MAX, it detracts from the overall package.
