A 662-horsepower production Mustang, powered by the most powerful production V8 in the world. What if it’s too dangerous to drive on public roads? What if it only belongs on the track, and even then it scares the day lights out of all but the most gifted drivers?
Well, it turns out the 2013 Ford Mustang Shelby GT500 is completely drivable. After all, it’ll lay down two black stripes from here to the county line, and won’t even break a sweat doing it. But it is far from the utterly unruly beast we expected.
Let’s call it a sophisticated beast. We try not to get too hung up on numbers, but we’re talking 662 hp at 6,500 rpm and 631 pound-feet of torque at 4,200 rpm. Those are monster numbers that simply cannot be overlooked.
Ford’s Special Vehicle Team (SVT) that built the GT500 didn’t just bore the old 5.4-liter out to 5.8 liters. The SVT engineers also increased the compression ratio to 9.0:1; added high-lift cams from the Ford GT, a larger oil pump, piston squirters, two 5.0-liter fuel pumps, larger injectors and three quarts of oil capacity; swapped in a 2.3L TVS supercharger; fitted a larger intercooler; and designed a massively upgraded cooling system.
And despite over 100 extra horsepower versus the outgoing GT500, the new car actually sees a 1-mpg improvement in both highway and combined EPA ratings, to 15 city/24 highway/18 mpg combined, yes a more efficient GT500.
