While much of the US was shivering under Arctic conditions, there were no such problems in Nevada on Monday as the new Formula E fully-electric race car made its d?but public appearance on the city's main thoroughfare, the Las Vegas Strip.

The Spark-Renault SRT_01E was put through its paces with a high-speed display around the Mandalay Bay Resort and Casino and up to Caesars Palace Hotel and Casino.

It was the first chance that invited guests, media representatives and fans had been able to see what the new car can do in the hands of a driver such as former F1 star Lucas di Grassi, who was given a police escort for his outing.

The Formula E world championship is due to launch in September 2014 and will run into the spring of 2015 and will consist of ten teams, including Drayson Racing, Andretti Autosport, Dragon Racing, DAMS, Super Aguri and Virgin.

The 20 drivers will compete on 10 city-centre circuits around the globe, including two races in the US in Miami and Los Angeles.

"Since the FIA launched Formula E just over a year ago, the progress and interest in the series has been overwhelming," said Alejandro Agag, CEO of series promoters Formula E Holdings. "When we started we had no cities, no teams, no broadcasters and no car.

"Now we have all these things so to be able to showcase our new car to everyone involved, and of course the fans, is a very proud moment."

Agag said that this week' event in Vegas would be the first of many roadshows we have planned over the coming months, as the organisers "want as many people as possible to see, and hear, what we believe is the future of motorsport."

Capable of speeds in excess of 150mph, the zero emission single-seater has been built by French-based Spark Racing Technology in association with a consortium of some of the leading names in the motor racing industry.

Dallara has been responsible for the chassis, while Williams has been behind the battery design, McLaren for the powertrain and electronics and Renault for overall system integration. Tyres for the series are being provided by French manufacturer Michelin.

Vegas is currently hosting the International Consumer Electronics Show (CES) and the Formula E car will be displayed on Qualcomm's stand in the Central Hall of the Las Vegas Convention and World Trade Centre for the duration of the show.

Qualcomm Incorporated is one of Formula E's Founding Partners, and is also the championship's Technology Partner.
