http://www.teslamotors.com/ to find out all about that electric supercar.
Cost about 100 000 $
0 to 60 in under 4 seconds
Battery Life Useful battery, 100,000 miles
Range 245 miles (combined city/highway )
So, its a super car, with all that comes with it (brake, suspenssion, balance, handling, ect), but its an electric motor that made it run, and its a real beast, because electricity got way more pentential then gasoline.
Still got nice numbers, the battery change is about 100 000miles, not bad if you consider that few people, time and money are put in this technology. When (I hope it will come one day...), or if, this start to have some sells on the market, and if GM and the others big name put the money into it, we could have some great battery with long range at a good price. Its all about supply and demand...
