I was musing over the thread about IM5/6 consumption of around 2.8 miles/kWh and wondering if anyone has done a study to find the sweet spot in terms of battery capacity vs. range - or at least a graph plotting the relationship graphically.
In other words, are we really gaining much by increase of capacity beyond say 80kWh or is it just a law of diminishing returns? Obviously a 100kWh vehicle will be heavier, so there will be a loss of efficiency. But then that vehicle will be more expensive and hence need to be bigger and more lavishly equipped to justify the price, which in turn will make it even less efficient.
