In the past we've reported on heat maps depicting concentrations of other plug-in vehicles in the United States, such as the BMW i3.  VoltStats.net, a database of Volt owners who have voluntarily allowed the website to collect usage data from their vehicles through OnStar, now offers a heat map for the Volt as well (above), in addition to their previous map that has a push pin for each town that has a Volt.

Similar maps also exist for the Spark EV and Cadillac ELR, though their limited sales to date do not paint as interesting of a picture.

A quick look shows many of "the usual suspects" for popular locations, as well as a few possible surprises.  Are you surprised by any of the popular locations?

VoltStats.net shows (by default) this Owner Map, with a Push Pin for every Town that has a Volt.
