I just won the purple concept car from the US/UK race and it's pretty cool, but for some reason when I get up to 4th or 5th gear the controller starts vibrating and I can't seem to get any power. Speed starts dropping, as do my revs and I can't seem to keep it above 115. wtf? I didn't tweak the car at all, just raced it as I got it. Any clues?
