We head to the 2012 Los Angeles Auto Show
for a sneak peak at the latest cars and concepts to hit the green scene. Chevrolet
Spark EV Chief Engineer Chuck Russell gives us the lowdown on Chevy's first all-electric vehicle and BMW's Manuel Sattig shows off new variations of the plug-in BMW
i3 and i8 concept vehicles. We also check out the all-electric Fiat 500e and heavy-duty Mercedes-Benz
Ener-G-Force fuel-cell concept.
