I would like to see the official Renault specs on that 67 mpg figure. Reason is, the last time I saw a figure like that from an ICE, it was a simulation for the Scuderi split cycle engine technology which was 65 mpg. If that 67 mpg figure is indeed reality from Renault (which I would applaud, by the way), then imagine when Scuderi and Tour Engine come out with their split cycle air hybrid versions in both gasoline and diesel. HCCI so far hasn't even come close.
