I found this new link yesterday. I did not find many new information but someone might find it very informative. It is interesting to see the Diesel Hybrid Vehicle in the road to the ultimate eco-car. http://www.toyota.co.jp/en/tech/environment/hv/index.html
Nifty. It's nice to see Toyota acknowledging the they need to produce a PHEV. Now if they would.. ahem.. "Just Do It".
