REVAi: Кішкентай электр көлігінің тарихы мен ерекшеліктері

is a small micro electric car, made by the Indian manufacturer Reva Electric Car Company between 2001 and 2012. By late 2013 Reva had sold about 4,600 vehicles worldwide, in 26 countries. Production ended in 2012 and the REVAi 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.

The REVAi is a small three door hatchback measuring long, wide and high. The car can accommodate two adults in the front and two children in the rear. The back seats can be folded down to provide cargo space. The maximum passenger and cargo weight is
The REVAi is intended for city trips and commuting, particularly in congested traffic. It is registered in Europe as a heavy quadricycle (category L7). It may be exported to the United States, with a speed limiter that limits the speed to twenty five miles per hour, for use as a neighborhood electric vehicle (NEV).

The first model, produced from 2001 to 2007, was simply called REVA (G Wiz in the United Kingdom). Its power flowed through a 400 amp motor controller to a DC motor rated at , with a maximum of Power came from eight 6 V, 200 Ah, lead acid batteries located under the front seats and wired in series to create 48 V. This model did not have the strengthened chassis that allows subsequent models to pass a crash test at .

In January 2009, a new model was launched, the REVA L ion. It is similar to the REVAi, but powered by high performance lithium ion batteries, which reduce the car's curb weight to , offer greater acceleration, reduce charging time to six hours, and extend the nominal range to The performance of these batteries is also less affected by variations in temperature. An off board charging station is available, which requires three phase power and gives a 90% charge in one hour.

The REVA is exempt from most European crash test rules, because its low weight and power registers it in the European "heavy quadricycle" category instead of the "car" category. The UK Department for Transport found "serious safety concerns" after crashing a now discontinued G Wiz at into a deformable barrier on 24 April 2007, which is part of the normal test for production cars. Likewise, a test commissioned by Top Gear Magazine that followed the Euro NCAP crash test specifications found that the occupants would suffer "serious or life threatening" injuries in a 64 km/h (40 mph) crash. In October 2010, a fatal accident in London occurred between a G Wiz and a Škoda Octavia, with the driver of the G Wiz, British scientist Judit Nadal, being killed. The coroner Andrew Walker was quoted as saying about the G Wiz at the inquest: “What concerns me is that this vehicle was destroyed in this collision in a way that I have not seen a vehicle destroyed before” but he did not recommend further action regarding the vehicle's design. Subsequently, the government ordered an investigation into the safety of small electric vehicles. The BBC programme Top Gear has consistently and incessantly lambasted the G Wiz, named it the Worst Car of 2007 and then even blew it up later in the same episode; co presenter James May referred to it as "the worst car for this year and indeed for every other year whilst we have breath in our bodies — it is the most stupid, useless and dangerous car ever to stalk the earth. It is totally terrible, and disgusting." In July 2004, The Independent reported Archie Norman owned a G Wiz to commute around London, and outside London, he drove a Volkswagen Golf. In October 2013, Top Gear Magazine placed the G Wiz on its list of "The 13 worst cars of the last 20 years." In December 2016, twenty G Wiz vehicles were destroyed in an episode of The Grand Tour and continuing on the theme of lambasting the car, which the presenters started whilst working together on Top Gear.
