Ford has only built two generations of its GT supercar, and Kelley Blue Book’s Karl Brauer — who owns one himself — puts the 2005 original against the 2017 successor to see exactly how far the engineering moved in twelve years. From a supercharged V8 to a twin-turbo V6 and an all-new carbon monocoque, the changes go well beyond styling. Owning one shapes how Brauer sees both cars, and it shows throughout the comparison. Watch how differently a decade of engineering plays out.
