Folks, a truck carrying 20 tons gets between 6.5 and 7.5 mpg. A Prius carrying a 200 lb man claims to get 50 mpg. So, a truck running so badly that its only getting 5 mpg while carrying 20 tons of freight will carry that 20 tons 5 miles on one gallon. For the Prius to carry 20 tons (40,000 lbs.) of 200 lb humans 5 miles, it would need to take 200 trips, which would be 1000 miles. The Prius would take 20 gallons of fuel to do the same work, if it was running perfectly and getting the claimed 50 mpg. So, the truck is 20 times more efficient than a Prius from the start, even if its running bad, and the Prius is perfect. Obama is cracking down on fuel-guzzling trucks? Your groceries are going to be more expensive if he does. The truck manufacturers are building the most efficient engines we can afford for them to, and transportation companies are doing everything they can to get every bit of that efficiency out of them. Its in their best interest, because a few 10ths of an MPG can save millions for a company with a fleet the size of Walmarts. Theres no conspiracy to keep trucks inefficient. Quite the opposite. Oh, in a city, such as Los Angeles or Houston or Dallas, a post-2010-model trucks exhaust contains fewer pollutants than the air contained before it went through the truck engine.
