Are the miles you're planning on driving from Sedona to Flagstaff (all uphill) or the other way 'round? Are the miles you're planning on driving cruising at a constant and sedate 45 MPH or are they all going to be on the drag strip? Are the miles you're planning on driving with an empty load, or are you about to hook up a trailer with a 500 gallon tank full of water? Personally, I'd be happy with a gauge that measured usable kWh capacity, with the actual numbers labeled. If the car leaves the factory with 50 kWh useable, the dial goes from zero to fifty. If you've used the car hard for a few years and you only get 30 kWh usable out of the pack, the dial still goes from zero to fifty but the needle never points past thirty. Couple that with a real-time display that shows you power output in kWh / mile, and most people will be able to intuitively answer any question they might think of. It's also a direct parallel with what people are already familiar with in ICE cars: a tank that is effectively calibrated in gallons (even if it's not labeled that way) and, in many cars, an instant MPG reading. b& _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
