Types of green tunning includes:
- Electric vehicle conversion. An electric vehicle conversion is the modification of a conventional internal combustion engine (ICE) driven vehicle to battery electric propulsion, creating a battery electric vehicle. In some cases the vehicle may be built by the converter, or assembled from a kit car. In some countries, the user can choose to buy a converted vehicle of any model in the automaker dealerships only paying the cost of the batteries and motor, with no installation costs (it is called preconversion or previous conversion).
- Hybridization: change to a hybrid electric vehicle. One can use an aftermarket kit for the powertrain or use a hybrid adapter trailer.
- Pluginization of hybrid cars. A plug-in hybrid electric vehicle (PHEV) is a hybrid which has additional battery capacity and the ability to be recharged from an external electrical outlet. In addition, modifications are made to the vehicle's control software. The vehicle can be used for short trips of moderate speed without needing the internal combustion engine (ICE) component of the vehicle, thereby saving fuel costs. In this mode of operation the vehicle operates as a pure battery electric vehicle with a weight penalty (the ICE). The long range and additional power of the ICE power train is available when needed.
- Extension: adding a baset trailer to extend the range of a battery electric vehicle or a plug-in hybrid electric vehicle.
