Plug-in hybrids visit DC
As for the price, the current estimate is 10-20% more than hybrids. There's also some interesting discussion about how these cars could be integrated with large-scale renewables to help balance the power grid.
From the calcars.org press release:
On May 18, CEOs of the Big Three automakers came to Washington DC to meet with Congressional leaders and discuss the industry's woes. We saw an opportunity to introduce Congress to a solution using existing technology that can make a big dent in our oil dependence and also help Detroit back to prosperity -- should it choose to take the opportunity. After a whirlwind fundraising campaign CalCars flew in one of its plug-in Priuses from California, and the journey began. This was the first time plug-in hybrids were seen in public in our nation's capitol.
