The superwhat?

Another comparison: nine 88-92 manual transmission Festiva owners reported avg FE of 40.45 mpg (US) at fueleconomy.gov. Compare to EPA combined estimates of 38-41, depending on the year.

Darin what's the CdA of the metro is it about .33 or so?
I've notice that with the Daewoo (1.6L), smallest engine I've driven, if you make the slightest imput to the gas there is a drastic increase in fuel and manifoild pressure with no response compared to the bigger engines. There is a huge lag and It's almost like you need to just think about the desired imput and then wait and it will get to where it needs to be with out much decrease on the FE if your patience.
I wonder it the test on the dyno for epa are really precise and that the average driver of the 1.6l and down engine, to stay with the traffic flow, make an imput and the delayed reaction, because of the lack of HP, they keep putting the foot into it to get the "normal" acceleration which really kills the FE.
Or it could be as simple as with the Prius that people think that anything over 40MPG is outstanding and don't try as hard because it twice what everybody else is getting.
Just rambling, it will be interested to see what up come up with.
