EPA docs reveal how Tesla's long-range Model 3 covers 310 miles

The electric vehicle has an 80.5 kWh battery and a 258-horsepower motor.

Elon Musk once said that Tesla couldn't fit a 100kWh battery into the Model 3, but he didn't specify what kind of battery the car will have. Now, a bunch of EPA certification documents have finally revealed that the long-range version of the all-electric sedan is equipped with a 350-volt, 230-amp-hour battery pack. If you compute for the battery's kilowatt-hour value using those numbers, you'll get 80.5kWh of max capacity. That's what gives the long-range Model 3 variant the power to travel 310 miles between charges, only 5 miles shorter than the 315-mile range of the Model S and X. Tesla upgraded those vehicles' batteries to 100kWh in late 2016.

In addition to demystifying the long-range Model 3's battery, the EPA documents have also revealed that the EV relies on a 258-horsepower motor. The documents detail the test procedures the vehicle underwent, as well, along with their results.

EPA's docs are all about the $44,000 long-range model, though, and contain nothing about the standard variant. Considering the standard version can only go 220 miles on one charge -- and costs $9,000 cheaper -- it most likely has a smaller battery pack. If you do get the long-range Model 3, you'll have a car that can run up to 140 mph and has the ability to go from rest to 60mph in 5.1 seconds on top of being able to cover 310 miles in one go.
