The first of what we'd term "real cars" from Tesla, the Model S promises to deliver up to 350 miles of highway range--at 50 mph--and about 250 miles of range at 70 mph. Best of all for those looking to replace a gasoline-powered car with a Model S, driving at slower speeds could expand the range beyond 400 miles--up to about 460 miles at 20-25 mph. Of course, acceleration from a stop will reduce this figure, but it shows the 85 kWh battery pack is capable of some serious energy storage, effectively tripling the range of the much smaller Nissan Leaf under similar conditions.
In EPA test cycles, the numbers are a bit less impressive, but by no means lackluster: using the new 5-cycle test method, Tesla says the Model S with the big battery pack rates 265 miles range. Tested under the older two-cycle method used for the Tesla Roadster, it would get a rating of 320 miles.

Tesla says it has plans to deliver as many as 6,000 Model S sedans this year, with production ramping up to 20,000 cars in 2013. The first year's run was sold out in late 2011, with 6,500 pre-orders on the books.
