The REVAi, known as G-Wiz in the United Kingdom, is a small micro electric car, made by the Indian manufacturer REVA Electric Car Company between 2001 and 2012. The REVA sold about 4,600 vehicles worldwide by late 2013 and was available in 26 countries. Sales in the UK, its main market, ended by late 2011. Production ended in 2012 and was replaced by the Mahindra e2o.
In many countries the REVAi does not meet the criteria to qualify as a highway-capable motor vehicle, and fits into other classes, such as neighborhood electric vehicle (NEV) in the United States and heavy quadricycle in Europe.
The vehicle was originally known as simply the REVA, but was then improved and renamed the REVAi. Taken together, the original and current models made the best selling electric vehicle in the world until late 2009.
