Tesla: I would like to have (more) advanced dashboard "gauges" MODE

This would not be for everyone. Current clean design is good and what I'd like to have may be confusing or complex to some, but I am interested in it... Specifically:

a) The consumption "gauge" should also indicate the rated (or ideal, if chosen) consumption for the current speed. Essentially the rated Wh/km (or Wh/mi) multiplied by current speed. Could be indicated the same way as the cruise control setting, for example and would be more helpful than current indicator when people try to maintain or beat the rated range.

b) Split (stacked) indication as to how much energy is being consumed for actual motion (motor, regen) vs. everything else (heating, cooling, etc). Since regen is negative it may and will overlap the other one always but that can be represented by rendering it as semi-transparent, thus a sort of colour coding...

c) Either change or make a new "instant" Wh/km (or Wh/mi) consumption and projected range. I do know that this will jump up and down like crazy but, what can I say, I'd like to have that option.

d) Current energy graph averages segments differently for different range settings (10/25/50 km or whatever it is in miles). This tends to reduce the amplitude of the graph with greater range. I would like these to stay the same year as the screen has sufficient resolution to properly shrink/stretch the graph horizontally (only) without affecting amplitude.

e) A log of recent trips and charges instead of having just 2+1 of them. I'd like to see a split of how much energy was used for what (again, driving vs. otherwise) and would like to see the "vampire" drains too. I forgot to connect my car to the charger one night (wasn't important) and I think I lost some 50km (~30mi) in 24 hours in garage (not driven at all, went down from 280 to 230).

For other readers - this is just my interest. The car is great fun to drive and this is in no way required, just something I personally would really like to have. It may interest *some* others too...

I was thinking of something similar to your "a" suggestion while I was driving to Santa Barbara. The orange dial with number of kw used doesn't seem that helpful; I'd prefer if it could show Wh/mi, and have an "ideal" setting that lets you know if you are above/below the value for rated miles. Sure, I can use the energy graph for that, but it would be nice to use the screen space for map or something else.

Hopefully Tesla will allow third party app developers and make this information available to them so we can get all kinds of cool info about the car.

Main dial showing Wh/distance would be very confusing as it would keep going up with speed reduction and would make no sense at all while standing still. This is why I opted for (a) as I defined it above...

Isn't that already an option? I believe it averages over the last tenth of a mile. Is that not instant enough?

Doesn't the energy per distance generally go down with decreasing speed? Or are you talking about really low speeds, where the energy used for propulsion is much less than the constant overhead like heating or cooling?

In any case, if someone is interested in energy per distance, why would it be confusing to be shown exactly that?

No. This is actually similar to what "Chunky Jr." wants as well. I'd like it to be as instant as the energy consumption and/or speedometer updates.

Yes, but that is not what I am interested in - I like to see the details and instant effect of various "speeds of acceleration" on this. This applies at any speed. And nothing is really constant. Not even heating and cooling as that depends on many factors.

Furthermore, Ye said:

I agree it is interesting to have it. I want the same in (c), just in a different place. It would be hard to fit this on the central gauge and may not make much sense there. But it can easily be added to the energy chart and it can disappear altogether when not moving.

I'm curious why ICE don't seem to have all these gauges and displays.

@tes-s ... because they aren't as interesting :) ... As I said it isn't required, just something I'd like to have. ICE cars are very inefficient and throw energy away everywhere, all the time. Furthermore, there are no clean splits between "heating" (for example) and "driving" energy consumption so nothing to show there...

There are many interesting things in an ICE - plug timing, fuel mixture, mileage, etc. I guess ICE drivers don't care - or the manufacturers assume they don't care.

I guess I'm sort of stuck in my old ways - I look at mi/kWh periodically just as I looked at mpg periodically. Other than that, I just steer, step on the gas accelerator to go, and brake to stop. I'll have to learn how to use all the gauges, and maybe have my wife stay awake to monitor them all.

I've often thought about the wasted prime real estate that is now the dash display: I never look at the analog speed display and I think the instantaneous power gauge is close to useless. When I drive long distances and have to mind energy consumption, I always have a target Wh / mile in mind and then adjust my speed accordingly. So if the dash could at least display instantaneous Wh / mile (the equivalent of instantaneous mpg in an ICE car), it would make it much more convenient than having to depend on the energy gauge on the touchscreen that's updated only every 1/10 of a mile, I think.

So for my part, a customizable dash display, including some of the OP's suggestions plus instantaneous Wh / mile would be ideal.

Cruise control mode for Wh/mile not MPH! You'd probably be rear-ended...

Battery / Motor temperature for playing on the track. :)

Then you'd know when to hit the LN2 for that extra boost on the straightaway ;)

(No, I neither driven on a track nor have liquid nitro cooling installed, though both sound like fun).

@tes-s: +1

my old 5 series did have the fuel consumption per mile gauge.

@ye.
you are correct, the gauge goes to "infinite" when the car comes to a stop.
