Canada EnerGuide Tesla Model 3

[Jerk]

I’ve only done 1 trip in my model 3 awd and was able to charge at hotel overnight, so range was not an issue. Friday I’m going on a day trip with only level 2 charging available. I pulled out the window sticker to check the energuide consumption numbers and was shocked to see the numbers, they just didn’t seem to add up. The model 3 awd was rated at 2.1 Le highway which translates to 18.53 kWh per 100km consumption. I believe the usable battery capacity is 78.2 kWh, divided by 18.53 kWh for highway which translates to 422 km @ 100% charge on ideal driving conditions.
I was surprised to see the EnerGuide show a high 18kWh consumption rating.
Let me know if I’m barking up the wrong tree.
Is the Tesla trip display good at predicting range/batt?

Is the Tesla trip display good at predicting range/batt?

The number displayed next to the battery is an EPA rating mix of highway and street driving, so not as accurate for highway driving.

The trip computer is great, and reliable once you punch in the address.

In my observations, the Energy display (app launcher button -> Energy) is accurate. If you're driving a long distance, set it to "average range" and if you're using the built-in navigation, tap on Trip at the top right. That, I've found, is quite accurate in its predictions. Actual usage vs Initial shows you how your driving conditions+driving habits contribute towards the range you are getting.
