The Sportster uses lithium-ion batteries from AEVehicles and motors and controllers from Azure Dynamics. The Sportster is available now and, although less powerful than the Dune Racer, it will still go more than 100 miles on a charge and charge up for $3 (according to Xtreme's numbers). That low recharge price will need to be used a lot to make up for the initial price of the electric sand car. The Dune Racer EV costs a modest $115,000 (yes, more than a Tesla Roadster) while the Sportster should be around half as much. Considering that Xtreme also sells a $225,000 gas-powered sand car, the 2008 Sandmaster Sandcar, that offers 800 HP. Yowsers. Xtreme is also working on a street legal package for the electric Dune Racer, in case you're into that. Check out a video from Xtreme after the break.
