Obiviously, more than You. The info I find state other wise 1980 deville weighs 4,200# a 2000 deville weighs 4,011 #Wrong again overdrive isn't the only reason they get better mileage.. Aluminum engines, radiators, intakes, etc,etc
Not even close, or you wouldn't have to use misleading statistics, commonly called apples-to-oranges.
A 1980 Deville was 4,178lbs (curb weight), and had an overall length of 221".
A 2000 Deville was 4,047lbs but was only
207" overall length. It's a foot and a half shorter, and only weighs 131lbs less.
Curiously, the 2013 Caddy XTS is just over 4000lbs, and is only 201" overall length. If cars were getting lighter, as you suggest, the weights wouldn't be extremely similar while the size continues to go down.
My 2012 Ford Taurus work car was 4,224lbs, and only 203" long. How could it weigh MORE than a 1980 Cadillac Deville that's over a foot and a half longer if cars are getting lighter?
I already gave you good examples of cars that have stayed about the same size, and gone up dramatically in weight, and now we see cars that are much smaller physically, but staying the same weight, or getting heavier. Short version, your argument that cars are getting lighter is completely wrong.
Not that we need more to completely disprove your theory, but what the heck....base model Ford F1/F100/F150, 4x2, short bed, standard cab, manually tranny, and 6cyl engine over the years:
1950 - 3,100lbs
1960 - 3,200lbs
1970 - 3,500lbs
1980 - 3,800lbs
1990 - 3,800lbs
2000 - 4,300lbs
2014 - 4,685lbs.
Yeah, those old vehicles were soooo much heavier than modern versions....LOL.
