Looking at our first really long trip from Yass to Brisbane via Dubbo, Tamworth etc and then back down the coast before going inland via Katoomba…I’m quite comfortable with the 400-430km range under most conditions so it will be interesting to see the car’s performance since I have moved to night before 100% charges now and recharging at 10-30%.
Hmmmmm...... You won't get 400-430 driving at 100-110 on those open country roads without serious amounts of tailgating.
You have the same "77" as me, yeah? I've done the trip from Sydney to Adelaide multiple times now and the most I ever plan on doing between charges is 300km, and even then I make sure I've either charged to 100% overnight or am at least @ 90% SoC.
For example Hay to Mildura I overnight at Hay and start at 100% arriving at 15% max. Mildura to Hay I charge to 90+% and get to Hay with around 3-4%.
Power usage on those country roads is way higher than on the Hume when you are typically in a nice convoy with the air already being broken up and the road surface much smoother.
Where are you planning on charging?
You won't get from Yass to Dubbo even starting from 100% unless you intend to put along at 80k's the whole way...
Also, highly recommend signing up for the Tesla "membership" to get 18c per kWh off. It's well worth the $10 for the month if going on a long trip and using the open Superchargers.
Indeed, I strongly recommend planning the route around them (and the multi-node Kempower based units typically run by Chargefox and Evie).
Avoid like the plague the old single node Tritium NRMA chargers.
