Have a friend who has a brand new 2009 Shelby 500. I took a ride in it with him and he punched the throttle all the way to the floor at about 10mph and the tires won't even spin. Car accelerates pretty good but you would think tires would brake loose real good with the torque this car makes. Traction control is not truned on. Is this some kind programing to try to keep from damaging parts on car. We also have a friend who has a 2007 Shelby and this car if you do the same thing the car is all over the road spinning the tires. Has any one else have this year 2009 Shelby run across this same thing or does yours spin the tires with no problem. We are trying to figure is this normal for this year or does he have some kind of problem.
