"      The Formula E electric racing series will arrive this September with 10 teams signed up to participate in the inaugural season. So far, though, only one car exists\u2014the Spark-Renault SRT_01E. The Spark will serve as the model for all of the other Formula E cars during the first season. After the first season, the series will be open, meaning Formula E teams will be able to modify their cars and try out new technologies.  Housing a 440-pound battery pack that only lasts about 20-25 minutes, the Spark can hit 140 mph and accelerate from 0-62 mph in 3 seconds. Once the battery gets low, drivers will have to pit and swap out cars. Former F1 racer Lucas di Grassi is the official test driver for Formula E and took the car for a spin around the Mandalay Bay&amp;#039;s parking lot during this week&amp;#039;s CES. The car&amp;#039;s high-pitched whine lacks the raucous excitement we&amp;#039;re used to from race cars, but with viewers having the ability to give their favorite drivers a mid-race power boost via an online vote, we&amp;#039;re interested to see how the first race goes this fall in Beijing.
