Got my HCH2 last week...and I expected to get okay MPG for the first tank since the whole 300 miles break in period the car needs various RPM's . So I showed friends how it worked and pushed the RPMs up on occassions up to 3 or 4. I honestly attempted to drive it like a normal car and even took it on the expressway everyday pushing it over 75 and then going in to the first lanes when I wasnt rushing.

I filled up after reaching a half tank and got 51.0 MPG on the dash and about 53.3 calculated from the gasoline receipt. Tires came in already inflated at around 40psi and I used A/C when needed.

Pretty impressive or just lucky???
