Wanna learn how to get 100 miles per gallon from your hybrid? We get under the hood with CalCars. These Plug-in Hybrid Electric Vehicles (PHEV) shift pollution from a tailpipe to a power-plant. Even charging off the national grid, which is about 50% coal, these cars produce under half the net pollution! And get this, not only is electricity under $1/gallon, but these cars are only going to get cleaner as the grid gets cleaner!
