FYI, the Pruis came out in Japan seven years ago. It's had plenty of time to work the bugs out and is now in its second generation. The plan is to use this version for 3-4 years and then redesign it again.
Newer technology, batteries, bit better power - and stuff that into a larger, heavier car. You guessed it - a Camry.(the 2004 Pruis is about 80% as large as a Camry). The 4 cylinder Camry will go bye-bye and you'll get hybrid efficiency and the same performance for the same price.
GM and Ford - kludge city. They are TEN YEARS behind Toyota on building hybrid designs and the best they can rush to the market will be a first generation design with tons of bugs and horrible efficiency. Honda is already nearing the end of its first hybrid design and gearing up for a second generation as well.(Maybe 2-3 years from now, about the time GM anf Ford make competing designs.
Oh - Honda and Toyota are making a profit on these(if a slim one). GM? $40K or sell at a loss.
