Energy Graph equivalent on center display?

    Has anyone figured out whether or not the TM3 center display will have an equivalent to the TMS/TMX IC Energy Graph? Maybe someone even got a photo last night?

    In case it isn't clear I'm asking about the image below (not mine). I imagine there will certainly be something like the touchscreen Energy app, which shows consumption data over time and during trips. But often I find the IC version more useful when driving, because of the orange and green arcs that show immediate information about power use and regen.

    In the controls menu the options are:
    • Lights
    • Locks
    • Display
    • Driving
    • Autopilot
    • Safety and Security
    • Service
    Maybe it's under driving??

    There is a real time green line as you are driving but that's not a graph over time.

    Thanks, that's exactly what I hadn't noticed. It was difficult to spot in the test ride videos I've seen so far.

    That's a subtle re-implementation of the Energy Graph: relentless minimalism I suppose. No units, which fits with no kWh ratings on the TM3 battery options.

    Somewhere in there I also hope to find trip meters. Looking for these things gives us something to do, while production ramps up.

    The beauty is that since it's software upgradeable they can always add features.

    Right, or remove them in pursuit of elegant simplicity.

    To be fair to the TM3 UX designers, all the different ways to monitor energy usage in the TMS/TMX UI can be more confusing than useful. I'm technical, so I like having data available even if I don't really need it. But I may not be the target customer.

    I'm an engineer, give me units dammit!

    They want customers to think more in terms of miles instead of kWh used. It's more of a relative measure...

    That said, the test drive screens were set to not display certain info... every video from an actual owner shows slightly different info. For example, they displayed battery percentage instead of miles.

    With apologies for going off-topic, I think defaulting to percentage display is a good idea. Looking to the future it might be even better to do without percentages too — maybe. Just plug your destination into the trip planner. If you need to stop for a charge, it will tell you where and how long. Bugs and unexpected circumstances notwithstanding. The display could still include a battery graphic, without any numbers.

    I wouldn't like that: I'd rather have the numbers. But that's where Tesla seems to be heading in their pursuit of simplicity, and maybe they're right.

    Certainly I've been happier since I switched my display from RM to percent. Showing RM induces needless range anxiety, and percentage SoC is less misleading than rated miles. RM tries to estimate SoC, driving style, and conditions along your route — all at the same time. It's pretty unlikely that the route I'm driving matches the EPA cycle, so at any given time it's almost certain to be wrong about the latter two. It'll often be wrong about the SoC too, at least within single-digit RM deltas.

    Percentage display only pretends to know the SoC, and it has less precision. Oddly that makes it less inaccurate. It may still be a little off the true SoC, but it has less scope to get things wrong in a big way. Sure, that makes me responsible for driving style and conditions along the route. But I'm the one driving, right?

    That's playing with fire... People would revolt.

    I would actually prefer a kilo-joule (kJ) option. kW•Hr is a stupid unit.

    I see you want a 270000 kJ car, nice.

    Better expressed as 270-MJ. They could badge it as 250, and 350 for the premium model. Some would hold out for 500, and start rumors about 1-GJ coming soon....

    This would be perfect if they could optimize the efficiency to 1 MJ = 1 RM.
