Hey ribit - Yeah it does cause it's got the high performance turbo engine - but I do, from time to time sneak in a tank of regular - and it doesn't seem to mind.
It is incredibly fast. On our first road trip, over in Arizona, where the law is a bit easier on the speeder than in CA - I was cruising at 85 and tapped the gas and in seconds was doing 105. My bride asked me to ease off, so I did. It'll do over 150. It is a rocket ship.
