EV Sales In February, 2016

From an earlier post:

Look at it this way. A study by Michael Greenstone and Thomas Covert of the University of Chicago and Professor Knittel concluded that at current battery prices, for an electric vehicle to be cheaper to run than a gas-power car, oil would have to cost $350 a barrel. 

Do automobile buyers understand that? Let's look at the February, 2016, EV sales. Remember: automobile sales hit new records this past month (February, 2016). I assume EV sales in February also participated. Let's look. First number, January, 2016; second number, February, 2016:

• Chevrolet Volt: from 996 to 1,126 (increase)
• Tesla Model S: from 850 to 1,550 (delivered)(increase)
• Nissan Leaf: 755 to 930 (increase)
• Tesla Model X: 370 to 400 (delivered)(increase)
• Chevrolet Spark: 139 to 216 (increase)

Numbers for all models not yet reported, but right now:

• Total EV sales (some hybrids): 6,291 to 5,392 (decrease -- but as noted several companies still need to report, including Ford (probably about 1,200); Volvo (about 300).

Mercedes appears to be the outlier showing mixed results, but decreased sales of the Mercedes B250e.
