DailyDirt: Making Lightweight Cars

from the urls-we-dig-up dept

Only about 15% of a car’s fuel actually goes towards propulsion, but making cars lighter would still significantly improve fuel efficiency. The trick will be maintaining the safety (or perceived safety) of lightweight cars… which also need to share the roads with trucks and cars that haven’t been on a diet. Here are some interesting links on materials that might make cars greener and lighter.

By the way, StumbleUpon can recommend some good Techdirt articles, too.

I can see the appeal of going green, but for me, there is nothing like having an enormous hunk of metal between me and and the other cars on the road. I do my best to keep a gap of air in the way too 🙂 but if that ever fails I trust in steel more than crumple zones and plastic bits, and no I don’t particularly care what the numbers say.

Though that maybe true to some extent, many of those safety crash tests are now conducted under slower speeds than what they used to be conducted under and they get similar results (I remember hearing somewhere that the testing speed standards changed and were lowered). and read the comments of that video for more insights into that test.
