There has been a lot of buzz surrounding Tesla’s Model 3. Whether it’s the production woes or its competitive pricing, it has been the most talked about car of the year, and now a key detail has been confirmed by the EPA.

The Environmental Protection Agency confirmed the range Tesla initially is 310 miles. Initial numbers often differ from the numbers official cars come with. That is not the case with the Model 3’s bigger battery, which will be the most efficient EV available right now.

To acquire the estimated 310-mile number, the EPA combines the number of miles the Model 3 will get from both city and highway driving. City driving will get 131 miles per gallon equivalent (MPGe) and 120 miles per gallon equivalent on the highway.

Unfortunately, the 310-mile range will cost extra. The base Model 3s that starts at $35,000 (and can go down as low as $25,000 when you take into account government rebates) will come with a battery capacity of 220 miles. The 310-mile range Model 3 will start off at $44,000.

Those numbers are on a par with Chevy’s Bolt, which offers a 238-mile range and starts off at $37,500. But it will be infinitely harder to get your hands on a Model 3 because Tesla can’t produce them fast enough to meet demand.
