The long-range version of the 2017 Tesla Model 3 comes equipped with an 80.5-kWh battery pack and generates 258 horsepower, according to a new filing by the Environmental Protection Agency. That filing also shows that the Model 3 uses a permanent magnet (PM) electric motor instead of the AC induction motors used in all Tesla products to date.
Although Tesla has released an overwhelming amount of information about its new low-priced electric sedan, the automaker has shied away from revealing certain details, including the battery capacity of the Model 3 lineup. Instead, it simply advertises its versions as "standard" and "long-range" models.
But now, thanks to information published by the EPA, we know that the long-range Model 3, which can travel up to 310 miles on a single charge, will have a battery pack rated at 350 volts and 230 amp-hours, or 80.5 kWh of capacity. Tesla says that with its 258-hp, three-phase electric motor, the long-range Model 3 will go from zero to 60 mph in 5.1 seconds.
According to Electrek, Tesla has responded to the filing by saying the capacity of the Model 3's battery is actually 78 kWh and that the larger number doesn't represent the true, usable capacity of the battery pack. Either way, it's higher than Tesla CEO Elon Musk's original estimate of a 75-kWh capacity for the Model 3 battery.
There's still no word on the specs for the standard Model 3, which is priced from $35,000 and has a range of 220 miles. But, based on the new information about the long-range version, it's likely that the entry-level model will have a battery-pack capacity in the neighborhood of 55 or 60 kWh.
A previous version of this story incorrectly referred to the long-range version of the Tesla Model S as a 2018 model-year vehicle. The EPA filing lists it as a 2017.
