CalCars and PHEVs Frequently Asked Questions

Tony Karrer Delicious EVdriven

Dont PHEVs just shift pollution from gasoline cars to power plants? But its monumentally less pollution , even on the national (half-coal) grid. The enthusiasm for ethanol ("flex-fuel" cars use E85, which is 85% ethanol and 15% gasoline) is welcome. We are not exploring PHEV versions of gasoline-only (non-hybrid) cars.
