Are you serious? That's horrific...
- keenerd 10y agoIf you think that is bad, you should reconsider your car. A big truck is 3x more efficient than a Prius. Take a look at the numbers and analysis presented by "Why are cars unable to match the efficiency of the 18 wheeler?" http://arstechnica.com/civis/viewtopic.php?t=41085 http://arstechnica.com/civis/viewtopic.php?t=41085
- chiph 10y agoOn a pounds per mpg basis, the truck is moving 9400 pounds (8.5mpg truck, 80,000 pounds), while a Prius is moving about 67 pounds (60 mpg, 4,000 pounds). If you look at the weight of cargo being moved, the ratios are even more in the truck's favor because it can carry 40,000 pounds, or about half it's weight (the Prius can't even come close).
- sverige 10y agoMost trucks can haul about 48,000 - 50,000 pounds, since typical weight for truck and trailer is about 30,000 - 32,000 pounds. Some lightweight OTR trucks weigh less, and day cabs even less than that. Definitely more fuel efficient than any car. Trains win the grand prize, but they can only run where the rails are obviously.
