My sons powerwheels has 18 volts
. I bet its faster than yours, lol! By tail happy you mean its light and comes around easy? If so no doubt, the 350 was worse. In my area (with in 15 miles of my house) there were four 350z's crashed in only two months. Im sure half was from crap driving. Anyways the 370 seems to be a little better in that department
