To say the Shelby GT500 is powerful is obviously an understatement. Under full throttle it does, in fact, do a pretty good job of holding you against the back of your seat. The exhaust emits a noticeable rumble at idle, an alluring song replaced by roaring and supercharger whine as pressure is applied to the go pedal (were he alive today, Beethoven could’ve taken a few pointers from Ford’s exhaust tuners). With that kind of temptation at our disposal we only saw 14.2 mpg after a week of driving, but some might be surprised that fuel economy was actually that good. EPA figures are not currently available.
