This is why I'd like to see the GOM have a setting to manually set the m/kwh if desired...

If you want to see how mileage estimates and energy remaining graphs are done right in an EV take a look at the pics in this thread

http://www.teslamotorsclub.com/showthre ... rmware-6-1

* % remaining right under the speed in the center focus of the dash
* navigation tells you how many % will be used by current trip plan, charge remaining at the end of that trip positive or negative and if you need to charge before then.
* navigation is smart enough to tell you if slowing down will allow you to make a trip near the maximum range.
* trip chart with projected power use for the trip vs actual, updated in real time as you drive. Awesome visualization that really educates, builds confidence, or shows how bad your trip plan is off.
* navigation understands elevation changes, weather, temps and the current car (tires, battery capacity, etc) and can use these to make the above trip planning more accurate.

we don't need a 17" screen in the leaf to achieve this but you can't waste space with stupid tree/vine/whatever the eco logo of the day is graphics that don't provide useful information for current driving and trip planning. You will have to have a usable MFD but I'm assuming since there is a backup camera already we have that covered.

for those not wanting to chase pictures this one says a lot to me. Even with the shorter range of the Leaf, software like this would go a long way to making the car seem more usable.

^ I'd get a kick out of a plot like that. It sure wouldn't resemble a straight line where I live! (But neither would it have much utility.)

I get along fine with a fuel gauge that uses energy units and has fine gradations. Gids work well, as would kWh displayed to one figure to the right of the decimal (tenths). I can figure out how much energy it takes to make the legs of my trips under various weather conditions. Since the miles/kWh can have gigantic variation, depending on terrain and weather, designing some sort of super GOM seems less useful. But it would be easier for newcomers to short-range EVs, I suppose. (And I guess that's why Nissan included the current wildly misleading GOM in the LEAF, which generates so much confusion, dismay, and angst among new LEAF drivers here.)

yep. In Summer, I set my efficiency to 4.4 MPK and Winter at 3.5 MPK. Both figures are actually a few tenths lower than what I average but always want a "bad case" scenario to judge especially if my trips (almost always is for work!) are time sensitive

not to harp on the obvious; its easy to do it right when you got that much money to spend. But having tried it before; inputting NAV really sucks unless you can do it the night before (like I do online now which automatically gets sent to my Droid) instead of 4:30 AM when leaving for work.

But ya, great system and with that kind of money involved it has to be. But for us poor folks...

At ~21kWh usable charge, the Leaf actually has the equivalent of ~5/8ths of a gallon of gas onboard.

*******

What the Leaf really needs is a direct heating defroster, on the windshield and maybe the front side windows, too. This would largely eliminate the cold weather hit on range - if you dress warmly, and can get by otherwise on the heated seats and steering wheel.

I'm not aware of a car that can go 84 miles on 5/8ths gallon of gas.

the less straight it is the more useful it would be. It takes elevation into account and will give you the slopes to expect during the trip giving you more confidence in the final estimate for remaining charge at the end of the trip. It also tells you the expected percent charge in 1% increments so you have a better idea of your reserve and time needed to charge at the other end.

The system lets you input Home and Work the two most common destinations and knows the locations of all the fast chargers around you the next most likely destination/point of origin. It's not like you have to do that much work to add a new destination and let it use your current position as the origin.

Carwings online has similar features in their route planning, takes into consideration elevation and the like. With some work on the user interface and making it quicker and more reliable they could do something similar to Tesla.

The perfect app for me would be Waze like with the ability to interrogate the cars SOC, battery temp etc in real time and calculate (and repeatedly recalculate) a route that would get you to your destination as fast as possible without running out of charge.

The Volkswagen XL1 will go 84 miles on 3/8ths of a gallon of diesel :shock:

Of course it is outrageously expensive and unavailable in the US.
And having set down in the driver's seat at its first showing in the US at the Society of Environmental Journalists meeting in Chattanooga, it is the most difficult to get in and out of vehicle I have set down in.

But it does go farther on a set amount of energy than the LEAF :shock:
