So if an ICE car can have a reserve fuel tank, why not a reserve battery pack for the Model S? This could be an add on down the road! How about installing an adapter or jack into the trunk cavity where the jump seats are stored? This connector would tap into another circuit that leads to the main computer system and be shown as the Reserve Power or Reserve Range. Using Tesla's battery tech, and maximizing that cavity's volume, could we squeeze another 50-75 miles out of this reserve battery? My thoughts are that if the Model S can tow a couple of kids (100 lbs?) plus luggage, perhaps we can better use that space for reserve range.
We need range that gets closer to ICE cars: 350 to 400 miles on a single tank. However, for my daily driver, the Model S fits the bill and then some!
