FWIW, Toyota also *limits* battery recharging to roughly 80% of maximum so as to prolong the batteries overall life.

Are they actually prolonging battery life / cycles, OR are they preventing premature battery pack replacements? the studies I have seen suggest that laboratory life is much longer even at "elevated" charge levels

One affects the other, so it isn't an OR proposition, but an AND.

By not charging to 100%, you are prolonging battery life AND preventing premature battery pack replacement.

Lab conditions are controlled, and the real world throws many more variables into the mix that likely reduce the longevity of any part.

Road Test not 400 miles

Tesla has been able to improve driving range by about 40 to 50% on the Roadster over the official 245 mile EPA-rated range.

Nothing about aerodynamics, just the battery pack.
