In a move that still appears bizarre, with the Model 3 launch, Tesla decided that talking about an electric car's battery pack in terms of kWh was passé. Until now, the brand has used kWh to badge its various models, so we know that a Model S 60 has 60kWh-worth of cells and a Model X P100D packs 100kWh between its wheels. The new order does away with that, much like when BMW ditched decades of badging logic. Instead, there's just a regular and long-range model, with EPA estimated ranges of 220 and 310 miles. But with barely a handful of Model 3s on the road—and a long wait in store of most of the preorder queue—the Internet is hungry for more details. After all, how else to bench race it?

On Monday, Autoblog appeared to have solved the mystery, at least in part. Tucked away in an EPA document (PDF) were the magic numbers for the long-range model: 80.5kWh, based on the fact that it's rated at 350V and 230Ah. The report also detailed the rear-wheel drive motor-generator unit, which is a 192kW (258hp) AC three-phase permanent magnet configuration.

But then, according to Electrek, Tesla corrected the record during a conference call with new investors: the standard Model 3 will have "just over 50kWh," and the long-range version will have 75kWh.

What we think Autoblog discovered is actually the maximum kWh rating for the Model 3's pack. Using the same V*Ah calculation for the equivalent document for the 2016 Model X 60D gives a figure of 87.5kWh—even though we know the model actually came with a software-limited 75kWh pack. And a look at the EPA report for a 2016 Model S 75 (the rear-wheel drive version) reveals 400V and 245Ah: 98kWh.

Still, there could have been even more confusion if someone had seized on the results of the Model 3's charge-depleting range test. According to the results on page seven, the Model 3 actually covered 495 miles (798km)! For comparison, the Model S 75 made it 343 miles (552km) and the Model X 60D went 268 miles (431km). The tests all appear to have been conducted on Tesla's dynamometer in Fremont, California, so the fact that the Model 3 ran 44 percent longer over the same test with a battery supposedly rated the same as the Model S suggests there's been a lot of powertrain optimization going on.
