    Recently almost all charging has been in the 60% to 80% area, the 85 pack was due for a range charge and seeing as we had a free day it was a good opportunity to get a few questions answered.
    Question 1. What has been the loss of usable capacity?
    Question 2. How far can this car go on a charge? This is a question we get asked constantly from many different people, it's hard to explain that it's not that important, and will be less important when fast chargers are common place across the country, we normally give an answer of 400-420kms if we needed to go that far, as a matter of interest during yesterday's trip we passed through 4 different locations with fast chargers, in the South West it's just not necessary to use the full battery capacity.
    Driving conditions were excellent yesterday, warm and dry, fairly flat terrain, mostly smooth surface, lots of holiday traffic but flowing smoothly, highest speeds 105kmh but lots of 80-90 around the outskirts of built up areas.
    To be honest if we drove the coastal road North of Perth getting 400kms would be hard work, the course road surface and relentless wind takes its toll on energy consumption.
    Anyway the answer to Q1 is a 3.7% loss of useable capacity after 69,000kms.
    Q2. When next asked how far we can go on a charge we can honestly say 452kms with the airconditioner switched on.

    That's impressive. I have a model S85. Single motor. When I charge fully it indicates around 385 km of range. I haven't tested to see how far I can go without recharging. What range was your car indicating when you had it fully charged before you drove the 452 km?

    Full charge shows 380kms typical range, ALTHOUGH ( in nice big letters) from what I understand charging the battery in the mid range (60% to 80% ) and rarely going below 20% before recharging throws out the accuracy of typical range to a small degree, a more accurate check is calculating the energy consumed compared to the original useable.
    It's probably not worth the effort unless your car has 50k or more on the odometer and you have the opportunity and time available to check.
    It's really pleasing to see how well the Tesla battery packs are holding up across the world, and to think in terms of battery developement they may be leading the way but in reality the tech is at the lower end of a very steep learning curve, the future is exciting for motorists, the big carmakers are going to have to work hard to build cars that last as long as the battery packs, their excitement will not be so evident.
