December 2012 alt-fuel vehicle sales continued to trend well ahead of 2011 figures and pushed 2012's sales of hybrids, diesels and plug-ins past the half-million vehicle threshold. Plug-in vehicle sales totaled 6,769 units for December, which was more than twice as high as a year earlier and just 15 units shy of October's monthly record of 6,784. Last year's plug-in sales, which were just shy of the 50,000-unit threshold (not including lower volume cars like the Tesla Model S) were spurred by consistent demand for the Chevrolet Volt extended-range plug in and a late surge of sales for the Nissan Leaf battery-electric.
December sales marked a 45-percent increase from 2011.
US alt-fuel sales last month totaled 55,096 units, up from November's 46,216 vehicles. December sales marked a 45-percent increase from 2011 and represented last year's second-highest monthly total, behind March's 57,130 vehicles.
