Pair of Shelby GT500'sEnlarge Photo
Another Mustang that returned to the scene with the retro redesign the Mustang has seen over the last couple of years is the Shelby GT500. Back in the day the GT 390 and the Shelby GT500KR were some of the fastest Mustangs you could get, with the later having a 428 Cobra Jet V-8. However, the boys at Top Gear have yet again brought us back down to reality. Have you ever wondered whether the newest GT500 really makes that 500 horsepower that is advertised? What about those classics, how does one of those hold up over the years? Check out the video below and see the answers in living color (keep in mind that horsepower at the crankshaft and at the wheels will always differ).
