Mercedes-Benz unveiled a trio of BlueZero environmentally-friendly concept cars. The car shown here is a pure plug-in electric car, the second is a hydrogen fuel cell-powered electric car and a third is a plug-in electric car with an internal combustion engine to generate power for longer range driving.
