The 500e supermini features several upgrades to complement its battery powertrain, including low-rolling-resistance tyres, a new front bumper, low side sills and aerodynamic rims.
In addition to this, Fiat has given one of the show cars a loud orange and white paintjob.
The 500e is due to go on sale in California from next year. However, there are currently no plans to bring it to the UK.
The news comes a week after Fiat announced the production of its millionth 500 model, since launching in 2007.
