Using Photoshop, I performed some crude measurements of the charging screen to estimate the Model 3's current state of charge to be about 31% with 95 miles of rated range. That extrapolates out to about 306 miles of rated range (!!) for a 100% charge.

Reasoning:
- The gauge fits about 3 of the green section (each measured by a different-colored line of identical length), plus another 25% of the green section.
- If x is the current SOC, then 3.25x ~= 100% SOC --> x ~= 31% SOC
- 95 miles / 31% = 306 miles
- The dashed line (target SOC) appears to be set to about 90%, which roughly with fits the calculations above.
If what we're seeing here is accurate and headed to production, then it would appear that the 75 kWh battery will indeed break the 300-mile barrier, which is exactly the kind of information that Tesla would want to keep out of public view... until now, apparently...
