I would like to know more detailed information about how the range for each scenario is computed and be given equations where we can plug in our own numbers, such as different ambient temperatures and how eco mode effects these, what does eco mode do in cold weather (you only said it reduces the a/c, not the heating), how will heated seats and steering wheel effect range when used in place of full cabin heating and in general what is the range using the cold weather package, not to mention when this package will be available. Basically, I want to be able to look at some cubic equation P(v), power required at a given speed, with the constant terms effected by climate systems (A/C, Heat) and idle energy (headlights, display), a linear term for rolling resistance and ascending and descending hills, a squared term that essentially captures changes in momentum due to acceleration and a cubic term with a coefficient of drag that calculates the air resistance, as well as multiple Coefficients of drag for each plane of the car (front, left, right, back, top, bottom) so that we can estimate how wind will effect range. When will the curb weight be finalized, and we'd like to know how adding more items to this weight will effect the power equation through changes in mass (if we know the base mass -- curb weight -- we can add in the additional mass directly). Finally, what is the battery capacity loss percentage under various scenarios, such as cruise control at 55 and massive stop and go traffic. Will we be able to see the battery degrade over time. For instance, will there be a way to see a 0.3% drop per month in range / charge, as your models seem to predict? Would we be able to see in that first month or year that the battery could store 0.3% or 3.5% for the first year? Is there a way for us to see how well our battery is holding up? Can we predict range if we don't know how much our capacity has shrunk?
