Well, as many have said, one really shouldn't compare the 2 vehicles, since Volt is a plug-in hybrid and LEAF is an EV. Thus, I don't believe that it's relevant to say "whether the LEAF OR [not "of"] the Volt will be the overall plug-in champ."
Having said that, I wonder if the 20000 figures is still an up-to-date # to be used? I've seen many articles using 12000 as a sales target for the LEAF. Still hard to achieve (that means 2000 vehicles / month).
With the slower momentum at end of year (economy, holiday season, and 2012 roll out now), Nissan maybe looking @ less than 1000 vehicles/month, unless the 2012 roll out nationwide does change everything.
Volt, OTOH, won't be able to match that 10000 sales target at all. Not Even Close. Supporters have been using the factory stoppage as an excuse, but that was July/Aug. With production at max output based on resource allocated, 1100 vehicle is extremely disappointing. TO reach that goal, Chevy has to sell 2500 vehicles per month. I haven't seen a $40K+ vehicle (MSRP) hitting that sales # for a LONG time.
The bright side is that there are still people buying. I just hope that this sales momentum isn't limited to the W. Coast and a few East Coast cities only.
Mr. Loveday, you did an excellent job. It is not easy to take stats like these and make meaning out of them in a unbiased way.
Contrast that with the Eeyores out there with their "sales failure" articles already published today.
