Traditional cars run on gasoline, while hybrids use gasoline and battery power. Now plug-in hybrids have revolutionized hybrid technology, as they recharge via electrical outlets and run on electricity for the first several miles before expending gasoline.
Power
Traditional cars run on gasoline with internal combustion engines, while hybrids run on gasoline and battery power with internal combustion engines and electric motors. Plug-in hybrids run on battery power for the first 10 to 40 miles before relying on gasoline.
Fuel Efficiency
If traditional cars average 25 miles per gallon, hybrids average 45 and plug-in hybrids average 100 mpg. Compared with traditional cars and hybrids, plug-in hybrids run on the equivalent of less than $1 a gallon.
Emissions
The California Air Resources Board claims that hybrid cars reduce greenhouse emissions by one-third and plug-in hybrids by two-thirds compared with traditional cars.
Price
Due to the expense of batteries, hybrids cost several thousand dollars more than traditional cars, while plug-in hybrids cost an additional 10 to 20 percent, as of 2010, according to the California Cars Initiative.
Considerations
Though plug-in hybrids save gasoline money, their high retail price means it will take years for plug-in hybrid owners to compensate for the initial cost.
