Electric-Car Range Extender Engines: OK Now, Can Do Better

A series hybrid, like the Volt or Karma, makes do with a smaller battery system that keeps the vehicle totally clean for almost all typical daily commuting, but still offers full normal range via the secondary, range-extending gasoline engine.
By 2014, we should see such series hybrids using gasoline or diesel engines, even turbines, designed solely to generate electric current.
These purpose-built range extending powerplants will be both very clean and much more efficient than what we see now in the introductory, "version 1.0" models of the Chevy Volt and Fisker Karma.
GM has said that the 2012 Volt will have a more polished gasoline engine and thus meet these more demanding standards. In not meeting these more rigorous emission standards, the Volt does not qualify for either the California $5,000 clean vehicle rebate, the electric vehicle parking permit, or a freeway single-occupant carpool lane permit.
