Never could figure out how to find the article itself, just this comment and picture.

Assuming this is true, it seems like some sort of physical threshold due to the limitations of physics in the trade-off between transportation power requirements and safety concerns rather than some evil plot of the auto manufacturers.

They’d sell a lot more cars if they could offer SUVs with mini-car mileage.

But the left doesn’t respect science anywhere near what they say they do, do they?

Lies, and damned lies.

The title is a bit misleading, because it ignores significant fuel economy penalties that are built into vehicles due to government regulations. Remember the early days of air pollution regulations which required automobile manufacturers to blow extra unburned fuel into engines, and then burn up the excess in catalytic converters, in order to decrease nitrous oxide emissions? Those were the days of 8 and 10 mpg passenger cars.

If you look at fuel economy before this time, and then compare it to current fuel economy, which uses three-way (simultaneous oxidation of unburned hydrocarbons and reduction of nitrous oxides, requiring oxygen sensors and computer controlled fuel ratios) catalysts, the fuel economy improvements haven't been so great. If you include this technology requirement, the fuel economy improvements have been enormous.

“precious fossil fuels”

Fossil fuels are about as precious as dirt. I’ve lost track of the number of reports of vast oil reserves discovered in and around the U.S.A., only to be left in the ground by (Democrat) law!

MPG/Weight

[mad_as_he$$]

Bull$hit. The Model t got like 8 miles to the gallon. Now if you take ALL miles traveled and divide by the fuel used you could get that number taking into consideration truck traffic. However, there are less gasoline stations per vehicle than EVER before so how does that compute?

I don't believe it. Who writes this stuff. An unknown expert in what? I went form 14 mpg on a 58 Chevy to 24 by some adjustment. I was not under EPA dictates at the time and gas was a whole lot better.

[Uri’el-2012]

it always takes a fixed amount of energy to move a given weight over a fixed distance

Isaac Newton knows more about gas mileage the the EPA

[mewzilla]

Gee, I wonder why Bubba never raised CAFE standards when he had the chance...

[Iscool]

I owned a couple of Ford Falcons which got 30 mpg...They likely weighed more than a model T...

Whoever authored this article is lying, or nuts...

Are we comparing cars traveling at the same speed? My sportute gets good gas mileage at 20 mph.

[wildbill]

I drive a 1994 Pontiac Formula (big powerful V-8) which still gets 21-22 actual mpg on the road and 15-18 in town.

I drive about 5000-8000 miles per year. I don’t think immobilizing this beautiful powerful car and picking up a slightly higher mileage car is going to make any meaningful difference to the planet.
