Tesla Model S X 3 road trip planning

I've chosen the cheapest configuration for all three Tesla models:

  • Tesla Model X 75D with a 75kWh battery - 237 mile range - 83.000 USD
  • Tesla Model S 70 with a 75kWh battery  - 248 mile range - 75.000 USD (including the 3000USD battery upgrade)
  • Tesla Model 3 50 with a 50kWh battery - 215 mile range - 35.000 USD

So if we're talking about a 500 mile long trip, you'll have to charge your Tesla at least twice (assuming you start with a full tank), by a total of: 
  • 127% on the Model X 75D
  • 117% on the Model S 70/75
  • 150% on the Model 3 50
The Model X and S can supercharge by default, so they can receive 120kWh from the supercharger, which means 50-60kW in 30 minutes. That is around 70-80% charge ... requiring you to charge after 220/230 miles for 30 minutes and once more for 15-20 minutes, assuming you only use superchargers.

For the Tesla Model 3 50 you don't have supercharging included in the price, so you can only charge at inferior charging stations, which output around 20kWh of power, getting you from 10% to 100% in about 2.5 hours. So on the 500 mile trip, you'll be stopping to recharge for about 4 hours total.

SUPERCHARGING THE MODEL 3 COULD BE EXCITING

If 120kWh supercharging will be as efficient as with the Model X and S, the Model 3 could charge from 0% to 100% in just 30 minutes, because it has a smaller battery. This may be extremely compelling for future Model 3 owners to opt for the 2500 USD free supercharging option. For the 500 mile long trip it would mean just 30+15=45 minutes of total charge time, instead of 4 hours at inferior charging stations.

THE CLOSEST UPCOMING MILESTONE FOR MODEL 3

The Tesla design team and engineers have their work cut out for them. In 6 weeks they have to finalize the entire car's structure and manufacturing process for V1.00. Elon Musk recently said, that any good ideas that come after the 6 week deadline, will be implemented only in future revisions of the Model 3.
