May 2016 wasn't lucky enough to bring numerical growth to plug-in car sales in the U.S., as 11,423 were delivered (some 1% below 2015).

However, we should note that sales expressed as a percentage was up, as May 2016 only had 24 selling days in it, as compared to the 26 selling days found in 2015.   Accounting for selling days, sales increased 7.2% (or an adjusted ~12,375 sales).

Roughly 50,000 plug-in were sold in the first five months of 2016 - which is up 13% year-over-year.

Market share in May stands at 0.74%.
