Sure, the 2016 will be different in lots of ways, but I'm struggling to find info on differences between the v1 Volts. Is there a single, comprehensive table somewhere that breaks this down? Or any info at all?

I ask because when I shop for common accessories that I would expect to fit all years of v1 Volts, I see compatibility with 2011-2013 for example, suggesting that it's not compatible with 2014-2015.

That particular one was for floor mats of all things, which I really expect are not different, but just poor e-com site maintenance. However, browsing the boards here, I've seen references to a few electronic features that were upgraded in later years (Hold mode?), and it would be comforting just to know what the differences are across the board so that every accessory I'm interested in doesn't entail a long Google session with ambiguous results!

Thanks for any pointers at all!

The floor mats have not changed. There are a lot of small differences between all the models. For instance the 2011-2012 have a 16kwh battery and use 60%. Late 2013 & early 2014 have a 16.5kwh and use 65%. The 2015 has a 17.1kwh and uses 65%. 2011 does not have kwh used on the center display. 2011 & 2012 have automatic charge door openners. 2013-2015 have a hold mode. 2011-2012 have the black on the body molding. 2011 & 2012 don't have an extreme cold setting for erdtt and erdtt starts at 25 degrees. This is off the top of my head.

2011: 5 years onstar, 16 kWh battery
2012: 3 years onstar, added button locks on door handles (keyless entry), tail lights slightly different, kWh used stat added
2013: 16.5kWh battery, added hold mode, mylink, no more dual tone color scheme, selectable ERDTT
REMOVED: 30gb HDD, DVD playback, changed default 120v charge setting to 8 amps.
2014: manual charge port door, slightly increased battery depth of discharge, exterior color options changed, 5k price drop
2015: 17.1 kWh battery, 4G LTE + wifi hotspot

I'm sure I missed a couple of things.

Good list. Couple of notes. Some of the changes occured late in a model year. Like some late 2012 Volts got the 16.5KWh battery and updated mylink.

Also of note the 2013+ Volts have body coloured roof and tail gate vs. the black roof and tailgate on all 2011 and 2012 Volts.

Edit:
Another - 2011-2012 Volts came with a 120V EVSE made by Lear (with a 8/12A selector). The 2013-2014 switched to a clipper creek EVSE. The 2015 has a different unit yet which I think is still a clipper creek unit.

All model years use the same 65% window.
The different % theory arose from a comment by WOT about the charge depth being lowered about 4% (~18% from ~22% in older years)
People logically assumed this meant 4% more battery, but no one has ever provided proof that is the case. Doesn't stop it from continually being spread.
Multiple people, myself included, have measured via OBD and a 2014 does not charge any more than 65% (83.5% top end)

I welcome people to continue to call me wrong, if they have measured proof
I've given up trying to explain this to people every time that rumour comes up, don't even know why I'm writing this now.

we should make a good list for the FAQ.

We had a Very good "Whats new list when The 2012 came out " with pictures ( I think a Volt dealer made the file ) ?

FWIW, GM has said that 2011-2012's use 10.3 kWh and 2013's use 10.8 kWh

10.3/16 = 64.4%
I had always heard that it was 10.4 kWh for the 2011/2012 Volts which would work out to 65% usable. Not that I have ever really gotten to 10.4 kWh, but if I cheat and overcharge the battery I can get to 10.3 kWh sometimes.

Thanks for all the replies! I agree, this seems like a good FAQ item. It sounds like a pretty limited list, I wonder if GM has/publishes a list that breaks them down by VIN range or build date, for the changes that came mid-model year.

I feel more secure thinking about accessories, and also that I'm not going crazy looking for the charging port door button that the Chevy site's user videos still show.

Not correct for all the world models eg.. 2013 for Australia = yes we have 30Gb hard drive ! Winner !
