2014 Spark EV built Oct 1, 2013 with 48,500 miles still charges to "82 miles" using A123 batteries (that were discontinued for 2015 model year). So "no degradation" or else GM installed an unusually large buffer atop the A123.
Snow driving yesterday was excellent with no loss of traction or control compared to my usual in-town prudent driving.
As with Tesla it would seem that GM is just not going to deliver batteries that fail prematurely.

A123 is LiFePO4 chemistry, one of the longer lived lithium ion chemistries, so no real correlation between that pack and what they are putting in the Bolt.
