Yeah, cars nowadays are way heavier than they used to be for safety.
Taylor - that is somewhat the discussion I was pointing to. It can be a brain teaser.
1956 Packard Caribbean Convertible = 6000 pounds. Huge V8 getting 18+ MPG.
This is true, I did not mention CO2, we can emit more NOx but have less CO2. Back in the 80s CO2 was considered harmless, we had two and three way converters that made it, but now it's the evil buzz word. I'm just saying that we (not suggesting we do) can make "dirty" cars that have incredible mileage with current tech.
Just food for thought...... I do enjoy these types of discussions
The catalytic converters still make CO2 out of VOC and CO. Hard to believe the amounts are that big, and it helps keep the ground level ozone down.
