The all-electric Tesla Model S sedan will start at only $57,400, or $49,900 after a federal tax credit. This is half the Roadster's $109,000 price and lower than the Fisker Karma Hybrid.

The yet-to-be-fully-unveiled Model S, with its all-electric powertrain, will surely garner more green-cred than the Karma (especially since Fisker is using a dirty old GM four cylinder) and a price tag of $87,900. Never mind the Karma has an unlimited range — the Model S is all-electric and cheaper!

The original projected price for the Model S was $60,000 but, after the Federal tax credit of $7,500, the four door Model S will cost buyers a mere $49,900. This news will undoubtedly charge the batteries of any would-be buyers, though we suggest they lock in their orders early . [Tesla via Carscoop]
