Oh I just found this article about the energy in the manufacture of a 2008 Toyota Prius:
http://www.wired.com/autopia/2008/05/the-ultimate-pr/
"As Matt Power notes in this month’s issue of Wired, hybrids get great gas mileage but it takes 113 million BTUs of energy to make a Toyota Prius. Because there are about 113,000 BTUs of energy in a gallon of gasoline, the Prius has consumed the equivalent of 1,000 gallons of gasoline before it reaches the showroom. Think of it as a carbon debt — one you won’t pay off until the Prius has turned over 46,000 miles or so."
I know 113 million BTUs or 1,000 gallons of gasoline sounds like a lot, but that's about 10 tons of CO2.
The
jtvang125's GS400 is suppose to average around 18MPG, which according to "fueleconomy.gov", at 15K miles, is 10.4 tons of CO2. A 2010 Prius which averages 50mpg emits 3.8 tons of CO2 for the same distance.. Alright, so let's just say the Prius emits 13.8 tons of CO2 for the first year of driving (combine fuel consumption + manufacture of car). Ok, so the Prius is worse than the GS400 that already exists, but that's for
the first year. After another 15,000 miles, the GS400 will emit another 10.4 tons of CO2, making a total of 20.8 tons of CO2 while the Prius will emit another 3.8 tons of CO2, making for a total of 17.8 tons of CO2.
So tell me, how is a NEW Prius "less green" than a used GS400? After 30K miles, the brand new Prius is already more green than the already existing GS400.. The point of that "wired" article is to point out that used vehicles that are
already efficient are more green in the short term than the Prius, i.e, they're more "cost effective".
I doubt it. The Prius will need new batteries by 100,000 miles and will probably only last until 150,000 where the typical driver will start to feel "nickel and dimed to death". The Hummer, which is built to take some off road abuse, will likely last a lot longer than 150,000 if its life is solely on-road.
The Prius has a warranty of 150K miles on the batteries for California cars and 100K elsewhere, and the vehicles' batteries have shown to last as long as 300K miles serving as taxis in various cities. The Prius vehicles could have lasted longer than 300K miles but they're retired as required by law once the odometer reaches 300K miles. (Applies to all taxis in New York and I believe California)

After mentioning that a number of Prius taxis have racked up more than 300,000 miles on their original battery packs, Thompson notes that the batteries are warranted for 150,000 miles or 10 years in states using California emissions standards and for 100,000miles or eight years in the rest of the U.S.

Jeremy Clarkson seems to hate anything that greens up or in any other way adds an eco label to his cars – and some environmentalists
don't exactly appreciate the television host either – so it's with some amusement that we learn that the
Top Gear team has named the Toyota Prius the "City Car of the Year." Turns out, the Prius really can appeal to almost everyone.
