The Leaf went on sale late last year.
Tesla vice president for worldwide sales George Blankenship said in a Web posting Monday that Tesla plans to sell a Model S Signature Series with the 300-mile battery in North America starting in mid-2012.
Tesla will sell versions of the all-electric Model S with 230-mile and 160-mile batteries later in 2012.
A right-hand drive Model S also is due in 2012.
The Model S with a 160-mile battery will start at $57,400, or $49,900 after a $7,500 federal tax credit.
Blankenship said the 230-mile option is expected to cost $10,000 more, and the 300-mile option about $20,000 more.
The Leaf sells for $32,780, or $25,280 with the tax credit.
Blankenship said Tesla expects to produce 5,000 Model S sedans in 2012 and 20,000 in 2013.
