My VX even on 33's feels good on acceleration. It can get up and go pretty well and when it was on the 18's and smaller tires it really moved out. It's no speed demon by any means but it is quick for what it is (some people's definitions are different, it's not "fast" but I can't compare it to my old Camaro, 2 different types of vehicles). I think there may have been something up with that VX.
