There are many factors that contribute to the Sparrow’s high efficiency. Below is a brief summary of how these factors combine to create one of the most efficient vehicles on the planet.
After a 50 mile drive, the Sparrow will recharge to a full pack in two hours on a J1772 station. When running at about 60 miles per hour the Sparrow will have consumed roughly 200 WH of electricity per mile which equates to $.02 per mile when charging off peak.
Comparing this to the price of gas, Sparrow gets about 150 miles per gallon.
This efficient little bird lives on bird seed!
