I'm not sure that I believe their assertion that cars have gotten lighter. Perhaps the real land-yacht monstrosities have been weeded out (and replaced with SUVs). But it seems like comfort and safety concerns, coupled with more power and better fuel economy have been causing equivalent cars to become heavier (and more expensive) over time. As an example, one of my first cars was an 84 VW GTI. It weighed ~2000lbs. Tr…
I have made this argument before on the internet and I have learned that it is a European vs American perspective. American cars in the 70s and 80s were monsters . Definitely heavier than modern cars. For example, here are 10 popular cars in the US from 1984. http://www.caranddriver.com/features/1984-10best-cars-1984-h... Audi 5000s: 2850-3100 lbs Dodge Daytona: 2830 lbs Honda Accord: 2300 lbs Honda Prelude: 2220 lbs…
I'm in Canada, and although I wasn't very old in the 80's, I remember seeing lots of Caprice Classics and Crown Victorias, which were around 3500 pounds, possibly more? My family have a Chevy Malibu wagon, which was a mid-size car but was definitely 3000+ lbs. Smaller cars were starting to become more popular, but there were still lots of monsters around.
So there were lots of heavy cars roaming the US and Canada in the 80s - but a new car of equivalent weight will usually use a lot less fuel, and be a lot more pleasant to drive.
