In February, Nissan announced it had delivered 50,000 Leafs globally, and just six months after, this had been increased to 75,000.

According to Travis Parman, director, Corporate Communications for Nissan Americas, the company crossed the 75,000 unit threshold some time this month – and in advance of full reported sales stats – thus it does not have handy the exact date for the new benchmark.

The all-electric Leaf is the only mid-sized pure EV sold in all 50 states, and was launched in this market in December 2010.

Its starting price is a mainstream-level sub-$30,000 and for all the hoopla of more expensive EVs, the Leaf has a growing fan base for those looking for everyday transportation without using gas or emitting hydrocarbons.

Its sales took off with the first adopters snapping up their examples in 2011, but the car’s popularity lagged through much of 2012 until Nissan switched over production to Tennessee early this year.

On the global level, the Japanese automaker has actually established relatively closer to point-of-consumption production facilities in the UK, Japan and U.S. and has trimmed prices while updating the car for 2013.

This year it has set several monthly sales records in the U.S. and its jump from 50,000 to 75,000 sold within this year may be one of its strongest indicators of success to date.
