Edit: Keep in mind that your over voltage figures are assuming that each cell charges equally; this will never be the case, unless you have some seriously high current capable balancing electronics.
Balancing would certainly be necessary, and I would probably resort to LED/diodes to do the work. I still need to look at the balance boards offered on Ebay. Perhaps they are more efficient, but I don't know if they would be good for 2.85v.

The other things I'm thinking is that the caps would only be over-volted when the car is driven, meaning that the majority of the time when the vehicle is sitting, the voltage would be trimmed to safer limits. Perhaps a very small over-volt for short duration is acceptable?

It would be nice if Maxwell had some 2.85v rated 350f caps to test on before shooting for the moon.
