The top-of-the-line Tesla Model S all-electric sedan reaches 0-60 mph in 4.4 seconds and has a top speed of 130 mph. Today we can add another number to the spec sheet: 89. As in, 89 MPGe (Miles Per Gallon equivalent).

That’s how the EPA officially rated Model S cars with the largest 85 kWh battery today, along with an expected range of 265 miles on a charge. Tesla had originally predicted a 300-mile range, which may still be possible if you’re dainty with the accelerator.

The 85 kWh battery is available in both the Model S Signature ($87,900*) and Signature Performance ($97,900) trims that will begin delivering to customers this Friday. An 85 kWh Model S Performance ($84,900) and 85, 60 or 40 kWh Model S ($49,900-$69,900) will begin delivery later this year. The EPA has not yet released figures for the 40 and 60 kWh battery-powered Model S vehicles. Tesla predicts an electric range of 160 and 230 miles, respectively.

The EPA rating places the Model S below its all-electric competitors in the U.S. market. The Honda Fit EV recently set an all-time record with its 118 MPGe rating, while the Mitsubishi i-MiEV scored a 112, the Ford Focus Electric is 105, and the Nissan Leaf weighs in at 99 MPGe.

Of course, none of those offer much in the way of performance, and none will turn heads like the drop-dead gorgeous Model S is sure to do. Its 265-mile driving range is more than double each of the other EVs, as well.

The Tesla is exponentially more expensive than its electric competition in every trim except the 40 kWh Model S, but for this combination of style, performance and eco-friendliness, that’s small pittance to high-income and green-minded buyers.
