In a previous article, we reported that current Model 3 owners are getting Supercharging speeds of around 460-480 miles per hour on Gen 2 Superchargers. That's a big improvement over Model S owners that only see low 300s for a Supercharging speed.

Why is the Model 3 so fast? First of all, the Model 3 can pull as much power as the Model S (115-120 kW), and second of all, the Model 3 has a much better MPGe than the Model S, so each kWh downloaded counts for more miles.

That's nice, but how are we predicting these big increases for the Model 3 on Gen 3 superchargers? In the previous article, we noted that a Tesla/EPA document quoted a maximum charging amperage capability of the Model 3 equal to 525 amps. One astute commenter, @Henrik, suggested that a good way to verify this was to look at the line size of the charging cable that runs from the charge port to the battery.
