Am I going to get 100 MPG once I install the Enginer Kit?
Enginer never advertises 100 MPG performance like its competitors. There are many factors affecting fuel efficiency including temperature, terrain, driving speed and charge frequency. Enginer made trade offs between short range fuel efficiency and total ownership cost. You should receive a 30 to 50% fuel efficiency improvement with the Enginer kit. You can get higher MPG if you charge it more frequently (charging at work) or drive exclusively in the city.
