Officially called the Spark-Renault SRT_01E Formula E, it will form the basis for every one of the 40 cars in the Formula E grid next year. It's not yet clear if there will be any scope for teams to deviate from the Spark-Renault's pattern.
Performance numbers will be announced at Frankfurt, but according to the FIA the Formula E cars will be able to accelerate to 100km/h in three seconds, and will have a maximum speed of 220km/h.
Compared to a modern F1 car those numbers may not seem especially exciting, but as all Formula E races will be conducted on street courses, it's arguable that higher speeds won't be necessary.
Battery technology will be crucial to success. Each Formula E race is expected to be just 45 minutes in length, with two pit stops to allow drivers to swap out of their depleted car and run 100 metres (!) to a fully-charged car.
So far ten cities have been confirmed as Formula E venues, with Rio de Janiero, Rome, Los Angeles, Bangkok, Beijing, Berlin, London, Miami, Putrajaya and Buenos Aires all on the calendar.
Only three teams have been confirmed for the 2014 season: Drayson Racing, China Racing and Andretti Autosport.
