Wiki to the rescue... Looks to be less inclusive (just gives one weight rather than a range)

94-96: 4221lb
00-05: 3465lb

Anyone interested in collaborating to collect this data (weight, FE, year, etc. etc. etc.)?

How many people compare the weights of cars they are considering. Not like high end bicycles... hehe

my point is that there may not be 1 specific high horse power car that drew those hp numbers up but probably a mix of quite a few (yes we'll pretend mustangs have a substantial hp also (just kidding if theres any 'stang fans here)) do affect the numbers

I'm actually more curious of where the data came from (to find methodology)... On the subject of the F body, they came off the table in '02 - but the hp number keeps rising.... So there's gotta be something else...

I would like to see that graph a bit more flat. I wonder what fuel economy the auto industry would be getting if average HP was still around 130hp.

I remember my 1980 Chrysler Cordoba weighing around 4,000 lbs and it was classified as a midsize car! Not only that but it's 5.2L V8 only made 120 horsepower when new.

What kind of fuel economy did it get?
