A green vehicle or environmentally-friendly vehicle is a road motor vehicle that produces less harmful impacts to the environment than comparable conventional internal combustion engine vehicles running on gasoline or deasel or one that uses certain alternative fuels. Presently, in some countries the term is used for any vehicle complying or surpassing the more stringent European emmision standards.
Cars with similar production of energy costs can obtain, during the life of the car (operational phase), large reductions in energy costs through several measures:
The most significant is by using alternative propulsion:
· An efficient engine that reduces the vehicle's consumption of petroleum or that uses renewable energy sources throughout its working life.
· Using biofuels instead of petroleum fuels.
· Proper maintenance of a vehicle such as engine tune-ups, oil changes, and maintaining proper tire pressure can also help.
· Removing unnecessary items from a vehicle reduces weight and improves fuel economy as well.
