Autoweek fails physics 101

Re: Autoweek fails physics 101
So in the "WIND" paragraph, drag is a function of velocity squared but in the next paragraph the Jeep always gets "17-18mpg" . . . something is wrong with the 'theory' and the 'practice.' The simpler explanation is the Jeep has a real problem at low speeds.

Re: Autoweek fails physics 101
In reading some of the almost-troll posts on these forums and many media stories, I'm flummoxed at how quickly *actual experience* gets ignored:
"You know, according to the physics and the math and the kilojoules and mass newtons and inch-pounds torque and KmWa-hours, the mileage on these hybrids just isn't ever going to be higher than a Hummer." "The Prius is only as efficient as a normal car on the highway." "These things are worse for the environment 'cause you have to build the batteries."
Yeah. 'Cause, as we all know, *every* small car gets 50 mpg highway. I mean, it's just no big deal. And when you work the physics, the HCH shouldn't get more than 35 mpg, so of course that's all it gets.
I don't think hybrids are gonna save the world, but how tough is it to step back and say, 45+ mpg, which most small-hybrid drivers have a reasonable chance of averaging, is, y'know, 50% higher than the actual typical average for cars and 150% higher than the actual typical average for trucks. People who are so quick to not notice this, you got to figure their mind was made up before they started their research.

Re: Autoweek fails physics 101
Doug, you are SO right on this. I've been harping this exact thing to others. So many people want to believe that hybrids are more hype than substance. I think it helps them justify "doing nothing" about their own MPG situation. "Well, if hybrids only get 40-45 MPG, then what's the point? I'll just continue driving my Cherokee (at 15 MPG)."
