Oops - thanks for pointing that out.

Even the runt of the litter Mitsu Mirage's engineers put it on a strict diet, with high strength steel in the structure and trimmed weight throughout. Thus the sub-2k lbs weight in U.S. trim and the flimsiest plastic wheelcovers this side of DIY coroplast discs. But losing a hundred and fifty lbs from an econobox isn't as exciting as dropping ~700 from a giant pickup.

Also I see nothing about aerodynamics.
Yup - huge oversight in the list.

I wonder if that is because it means so little in the EPA testing as they really don't have a 75 MPH sustained interstate mileage test even if that is what millions of cars are out there doing everyday.
I think we need to compare the ratings of 2 vehicles that have the same drivetrain but different aero characteristics (and which AREN'T also cheating by using the "same drivetrain = same rating" loophole that was closed because of Ford's silliness).

But the EPA 5-cycle highway segment actually has a stretch at ~60 mph, a run up to ~80 mph, followed by another stretch at ~70 mph. Looks like aero does count, provided the manufacturers use realistic coastdown data to set up the dyno ... ahem, cough Hyundai/Kia cough.

Still tons of room for improvement.
