Gotta be better numbers in that car! Gotta be!" That's what we all said when intrepid road tripper Carlos Lago reported his results of the "GT500 Quadrathalon". We're never sure of test results obtained on the road. We don't know a lot about the tester the carmaker sent us away with. Are the tires fresh, or have they been heat-cycled 100 times, and getting old, hard, and slow? Was the car broken in properly or at the hands of a bunch of mad journos attacking a racetrack for the first time? Even though Carlos is a solid, consistent tester, we wanted another crack at the new 2011 Ford Shelby GT500 Mustang on our own test track, using our regular gear, etc. So we did it. And found a pinch and an inch here and there, but nothing overwhelming.
In summary, MT resident road tester and hot-shoe Scott Mortara got the 0-60 down to 4.1 seconds and peeled off consistent quarter-mile runs of 12.35 seconds at 115.75 mph. Grip? Yeah, we got grip. The new tires really are better: 1.01g average on the skid. Braking virtually identical at around 103 feet from 60 mph. With slicks, this 3800-pound musclemaker would run well under four seconds to 60. All friggidy day.
