Offhand I would say "iterative development". A great deal of this car's capabilities are controlled by software, and from video I've seen of team Edison they followed a software model called "agile". In that model there is a constant process of refinement and rework; the initial software is functional but over time constantly improved. Among those improvements are significant increases in performance. You'd be surprised how different the efficiency of functionally identical code can be.Thanks for the info. Seems to answer the question.
So here is another question: At this point it's clear the MME will hit the range targets. Ford has suggested the test scores for emissions aren't entirely relevant for the EPA range. Assuming the EPA range is in fact equal or greater than the targeted range -- which is a good assumption -- how you explain the discrepancy?
I also suspect that iterative philosophy applies to the entire project, thus a great deal of time has been spent over the course of the last 6+ months tweaking not only the software itself but also the configuration of that software (ie tweaking parameters). Among those parameters are the balancing of acceleration, handling, and of course fuel economy.
Another point to consider: Ford knows the real numbers and that they will be out in less than a month; why would they insist that they'll meet the targets only to look like liars in a few weeks?
