Ultrafast electric auto is planned

Aero EV by Shelby SuperCars is designed to accelerate to 100 km/h in 2.5 seconds.

By the end of 2009, the US race car producer Shelby SuperCars (SSC) plans to build the world’s fastest electric car. With 1000 HP, the Aero EV (Electric Vehicle) will accelerate from 0 to 100 km/h in about 2.5 seconds and achieve a top speed of more than 330 km/h. Completely novel are the loading times for the battery, which the company specifies at 10 minutes. The power pack of the Aero EV is an in-house development at SSC. According to the manufacturer, the battery concept All-Electric Scalable Powertrain (AESP) is unique worldwide due to its scalable power, low weight, compact form and minimum loading time.

Experts question short loading times

Hubert Berger, head of the curriculum Electronics & Technology Management at the technical college Joanneum, also affirms that the future belongs to electric vehicles. "Such world record vehicles, although they will not be mass produced, clearly demonstrate what electric motors in vehicles are capable of."

According to the manufacturer, the range of the auto with a full battery will be between 240 and 320 kilometers. Within ten minutes at 220 volts, the company claims that the battery will be fully loaded. Berger considers this specification impossible: "For a range of 250 kilometers, you need at least 30 kWh of energy; that would require a 300 kilogram battery and loading time of nine hours, assuming the power comes from a 220V outlet," estimates Berger. Using three-phase current would reduce loading time to three hours, according to Berger.

"I think that we can make it faster, leaner and greener than other manufacturers," states SSC founder and chief designer Jerod Shelby. SSC Green will be the product line in the coming years as the company extends the All-Electric Scalable Powertrain to other vehicles. Plans call for medium-class autos with up to 200 HP, limousines and SUVs, as well as trucks with 1200 HP, buses and military vehicles.
