The first 1,000 cars will be the "Signature Series" equipped with a battery with a 300-mile range, and will feature "an extensive complement of options", according to Tesla sales boss George Blankenship.

Prices will start from $49,900 for a battery pack with a 160-mile range, rising by $10k for the 230-mile version and finally the range-topping 300-mile variant, which adds $20k to the base price.

Tesla expects to sell approximately 5,000 units in 2012, ramping up production to 20,000 units starting in 2013.
