You Prius guys do have a point about the clutch. I think that your PSD should last basically forever while us Honda guys will eventually have clutch (MT) or cone/belt (CVT) problems. It is nice to hear about the Toyota pack being modular.

BTW I don't think that the IMA pack is required to charge the 12v batt. The motor/generator combined with a DC/DC converter provides an alternator function. I'm almost sure that a Honda will run without the pack as long as the rest of the system is OK.

If anybody know more details on either brand of car running pack crippled please add your 2c. It looks like quite a few of us plan to keep our cars long enough that this will eventually be an issue.
