The mid-level Model S is rated for 208 miles of total driving range.

The Environmental Protection Agency has released its efficiency and range ratings for the mid-level Tesla Model S, which uses a 60-kWh battery pack.

The all-electric sedan will carry a 208-mile total driving range rating, which is slightly less than Tesla's initial 230-mile estimate. Economy is rated at 95 MPGe combined, close to the 99 MPGe achieved by the significantly smaller and lighter Nissan Leaf.

Those figures compare with 265-mile range and 89 MPGe ratings for the top-spec 85-kWh Model S, which hit the market back in June.

The 60-kWh version is expected to launch in late January, while the entry-level 40-kWh variant will arrive in March. The latter has yet to receive ratings from the EPA, though Tesla estimates its range at 160 miles.

Following Tesla's $110.8 million loss during the third quarter of 2012, company founder and CEO Elon Musk tweeted on Tuesday that the EV maker was narrowly cash flow positive last week. The company is hoping to stay in the black by continuing to ramp up Model S production; though just 250 examples of the model S have been sold thus far, Tesla aims to deliver a total of 3,000 units by the end of the year.

Tesla has ambitiously targeted Model S sales of 20,000 units next year.
