    Hi all,
    Getting a X75D shortly (June/July) and wondering about the "true" range

    Looking at the Tesla trip planner vs ABRP I'm not sure how accurate they are to each other.

    Wondering if the Tesla trip planner takes the car down to 0% in its calculation VS ABRP where its 10% (by default)

    Could anyone verify what one of the 2 attached plans are more correct or if you would say something else.

    Cheers

    *Both destinations are the same - Tesla doesn't seem to know the correct suburb for some reason

    I would add 10 minutes to each Supercharger stop for your first road trip until you get more comfortable with the cars consumption whilst you ar driving and for any unexpected events like rain or cold.
    Put the destination in the nav system in the car when you get it and it will do a similar calculation as you got from the web sites. I have found the nav system to be particularly accurate but haven’t gone below 15% on any trip where accuracy becomes critical.

    Hi @Icey, congrats on the car.
    The X75D will give you about 300kms without stress, in most conditions.
    Anything over 300kms will depend on conditions being good (low wind, normal temps, no rain etc).
    The S gives about 20% more range for the same battery, but the X sure is nice.

    EVTO aligns better with the results of ABRP than the Tesla planner. EVTO uses weather along with traffic so it could depend on when you take the trip as far as SoC values at the chargers and the times of course vary by how fast the chargers actually perform when you get there.

    Note that you are also getting close to the point where battery heating might play a role (10C) so if it's could when you take the trip, be careful. EVTO has a new battery heating calculation for these situations.

    If it is cold when you plan to leave on your trip, organise your charge the night before to complete just before you leave to ensure it is at the optimal temperature to start. That way, the car will not have to waste energy to bring the battery temperature up to the correct level.

    @meloccom - How often does it need to pre-heat in australia? I would of thought almost never...

    Fairly frequently in winter, below about 15 deg C IIRC.
    You may not notice it in normal driving other than unusually high consumption for the first few kilometres but on a long trip it can occasionally trip people up.

    @Icey plan your charging so it finishes just on departure, the battery pack has a little bit of pre-conditioning then.
    Also be very mindful of correct tyre pressures, that can have an effect on range.

    Yes 2 major contributors that are often overlooked, tyre pressure - low rolling resistance is key. The other huge one is wind, both wind speed and direction. From those details, headwind or tailwind component can be derived. Of course on a long trip, this can be highly variable…and calculating accurate & meaningful variations isn’t trivial. That’s why no app or website bothers with wind & weather data…with, as far as I know, 2 exceptions, ABRP - you have to input it manually and you can’t set windspeed for future legs of your trip. Not to mention ABRP is incredibly tiny & difficult to read on a phone.

    The other exception is EVTO, as mentioned above. It sources wind & weather automatically and will use forecast data to accurately calculate the effects the weather will have on your charge times & range for your entire journey taking into account weather for remaining or planned future segments. I put all the Queensland Electric Superhighway locations in Favourites and now I can quickly & easily plan trips all the way to Cairns. Definitely worthwhile.

    Actually you can set winds manually in evtripplanner too...so not entirely sure but it might be more accurate to say EVTO is the only one to automatically use weather forecasts for your entire trip including future legs.

    We did Melb to Adelaide and return last year in early September. Strong headwinds had a big impact between Horsham and Murray Bridge (equally, made the trip back much, much easier). We have a 100 and could just get 400km into the wind (but slowed to 90km to conserve battery - makes a huge difference vs 110kmh or even 100kmh)), so 300kms range from a 75 sounds right (and you have the advantage that the superchargers have now been built - we were using motels and the Keith showgrounds!).

    Also, re the cold, the regen braking doesn't work nearly as well until the battery warms up, so that also needs to be factored in if you have undulating hills or downhills early in the trip as the energy recovery isn't good (this is esp the case if you ever go skiing).

    Having said all that, no way I'd want to go touring in any other vehicle given how much easier they are to drive - esp on long trips.
