A Prius?
Where do we put all the lead and acid from the batteries when they need to be replaced?

i read about this over at http://www.nascarspace.com that is an insane amount of money, i doubt they even really get a return on it

You neglect to mention that Toyota's recent entry into the world of NASCAR racing is a major step toward getting the 'good old boy' segment into a vehicle actually made in the U.S. instead of just designed here. It is likely that Chrystler and others focus advertising toward NASCAR fans because they are the ones most likely to -continue- buying from U.S. vehicle manufacturers instead of checking the competition, and with Toyota edging in on this market segment, they'll probably continue the trend. Furthermore, it is considerably unlikely that someone who drives a Prius is ever going to switch for something that gets 1/3 the gas mileage, so why waste valuable marketing dollars there?

As an aside, Chrystler's marketing tactics where NASCAR is concerned do not focus on their trucks, but instead their Dodge Charger and similar vehicles. GM pushes their Chevy Impala and Monte Carlo as often as they mention the Silverado. Ford has a bunch of commercials about both its cars and trucks also. So far, it has been only Toyota who has marketed solely its full-size Tundra truck to NASCAR viewers.

now that the japs have built a powerful gas guzzling v8 engine the world is out of oil
to think it all started with the defeat of WWII NATO shares the MG engine design with japan who was ban from the manufacture of weapons of war began the asian industrial dominance sucking the blood from the free world

an electric car recharged by an oil burning power plant gets the equivalent of 8 mpg with the same carbon footprint do the math smart a$$

Aluminium is one third the mass of steel/iron. If an aluminium car is as heavy as a steel car , the aluminium car would look three times as thick as the steel car. For pound by pound, aluminum is much stronger than steel. But we really need one half the weight of steel car to make an aluminium as strong as a steel car. A 4000 pound steel car be as strong as a 2000-2500 pound aluminium car. Both would look identical and aluminium car would look a bit thicker on the skin. When an aluminium car crash, it crash like an accordion whlle a steel car fold up or twist. An aluminium car would save more fuel than an identical steel car two times the weight. We use steel because it is cheaper but we had to add hybrid junk or whatever to improve gas mileage. An aluminium car would be a lot simpler and cost less.
Why dont we use more aluminium? Because we are not producing enough new aluminium yet to support another industry like car makers. We have only enough for jets, ships, etc.. We need to build more smelters to produce more aluminium but couldnt because aluminium prices are still too low to be profitable.... Invest in ALCOA now!!

just think of all the Gas wasted at the race, yet they want us t buy gas misers, yet they can blow how many gallons of gas at Indy. it doesnt make Cents does it. peons will always be peons, the rich get richer and and only they have a right waste for profit.
