Nelson Piquet Jr., the Brazilian/British F3 champ, NASCAR driver, former F1 driver and current GRC RallyX driver, demonstrates how a Formula E car swap will occur during the race.

This is the first time we've seen the car swap demoed.

Each Formula E team will use 2 vehicles throughout the course of a single race, so a swap will be done by each team.

It should be interesting to see this swap under race conditions.  Our guess is that the speed of this swap could make it or break it for the race team.
