Under the Volt’s hood is a three-cylinder turbocharged engine that is used to provide power when the massive 400-lb. lithium-ion battery peters out, which is estimated to be after 40 miles or so. When that occurs, the little three-banger allows the Volt to motor on, and works to recharge the depleted battery, though the engine never powers the vehicle – it simply recharges the battery for electric propulsion. After the day is done, the Volt plugs into a regular 110-volt outlet and is good to go after six hours of current refreshment. Furthermore, Chevy’s juiced ride is designed to run on E-85 ethanol, the new E-Flex system is designed to also accommodate diesel or hydrogen, and in some cases, coal or natural gas.
