    @josephP... his comment wasn't an attack it clearly and concisely rebutted your comment. Stop being a troll, if you can't take someone retorting on a comment you make then don't make a comment in the first place. It is quite obvious that cars can have good mileage under perfect conditions, but most of us don't drive in perfect conditions and besides who buys a camaro or corvette to go "a few miles slower".

    @Shaman: Actually, you're incorrect in saying that it's greener to drive an older low-mileage vehicle rather than buying a new, higher-mileage one. The fuel a car consumes over its lifetime makes up roughly four-fifths or more of its carbon emissions profile, so fuel efficiency plays by far the largest role in its environmental footprint.
    For a more detailed explanation, see here:
    The MIT study referenced in that piece estimates that fully 75 percent of a vehicle’s lifetime carbon emissions come from the fuel it burns over its lifetime, with another 19 percent coming from the production of that fuel.
    Extraction of the raw materials that make up the vehicle adds another 4 percent, and only 2 percent of lifetime carbon is due to the manufacturing and assembly process.

    I'm not sure where some of the people commenting today crawled out of... @Joseph - Ask yourself a question - Will a Corvette get the same mileage as a Corolla under the same conditions? Then what are you talking about??? Corolla gets 30 MPG mixed under the same conditions that other cars with higher or lower MPG are measured, period. @Norman - Battery died... so what? Some renter left it discharged for too long and it got damaged. $50 batteries die; Toyota doesn't even make them. What does it have to do with the overall quality of Prius? I hope you don't think you're talking about the nickel-metal hydride battery since those can be completely dead on the hybrid and the engine will just drive it 100% of the time... I rented a Malibu once that couldn't drive straight and the tires were worn - so what does that mean? Am I going to badmouth all Malibus or GM now? @BigAssCanuck - They obviously don't make the Prius for you. Stick to your big engines - just keep in mind it does nothing for your size. @Shaman - Using your "logic" the greenest car would still be a mid- to late 90s Corolla built in the NUMMI plant instead of the bigger junk made at that time mainly in Mexico and Canada that would get you 185 HP out of the V8 - that does make Hummers look green.

    Prius Is Dirtier To Build Than Corolla...But Greener Than A Hummer. You need to fact check this article. You also need to quit misleading the public about the Hummer article. It was full of questionable statistics that made the entire piece silly such as the shelf life of a Hummer....by the way, a Hummer H2 is illegal to drive in almost every community in the country as they weigh over three tons. They are also illegal to drive on the Pasadena Freeway in California.

    If it was obvious and you just supported me, why are you attacking me instead of the article? This doesn't make any logical sense.

  • shaman Posted: 10/24/2010 8:27am PDT

    Greeneest thing to do is drive your good old V8 instead of crushing it and buying new japanese junk - think about it - first what a waste of perfectly good car all its components, then whole manufacturing process of this new toyota and atop of that shipping it from Japan…

  • BigAssCanuck Posted: 10/24/2010 6:54am PDT

    Maybe - but who really wants to drive a freakin Prius - seriously! I live in what can be considered a significant cold climate and Hybrid/Electric start loosing their edge in the cold - and once you put REAL snow tires on them...
    Plus - it is a Prius - the smug it generates amongst it drivers is intolerable!
    I'll stick to my small 8's and big 6's thank you - just direct inject them and when needed "something"-charge them and I'll be happy.
    Plus - Toyota/Lexus has lost their shiny quality gleam in my eyes. Just waiting for that next round of denied problems to surface!

    @Joseph P, Obviously...
    Actually, the Prius really does get an EPA Combined 50 and the Corolla really gets an EPA Combined 30 in its most efficient form, with the five-speed manual (26 mpg city, 35 highway). Since a recalibration of EPA ratings for 2008, we've found the EPA Combined numbers to be slightly higher than what we typically see in real-world combined driving conditions. Although the EPA numbers are estimates, they're scientifically reproducible, from rigid testing procedures and a set driving cycle.
    Yes, if you're cruising steadily and keep speed down, you can obtain impressive mpg figures in most vehicles -- more than 30 in a Camaro or Corvette, more than 40 in a Corolla (or 70 or more in a Prius, as we've seen a few times) -- but most real-world driving conditions, like traffic and hills, don't permit that.

  • Joseph P Posted: 10/23/2010 1:02pm PDT

    Whoever wrote this article obviously knows nothing about fuel economy. Mileage is completely determined by the road and the way the driver drives their vehicle. This is why the EPA has estimates, not precise miles per gallon, being it is imposssibly to determine. A Corvette or Camaro can achieve just as great mileage as a Corolla if driven nicely and a few miles slower. The first few sentences state a Corolla gets 30 at best, and seeing so, none of this article is probably accurate.

    I had the great misfortune of renting a Prius from Enterprise Renta Car at the Reno Airport. Very impressive until I was half way between Reno and Carson City (Read: Nowhere) when the battery quit. Nothing would work and the vehicle was virtually immovable. It took m,e four hours to get a tow truck that would tow it back to the airport. Never again!
    Another concern is: How can these giant baterry packs be recycled when the time comes and where?? It strikes me that whatever the process may be, it must be extremely an extremely toxic enterprise (Pun Intended)
