Nissan has projected that accumulated sales of its eco-car in Thailand will reach 100,000 units next month.
The Japanese carmaker attributed the success to the right timing, pricing and specifications of its March and Almera models.
Nissan, the pioneer in eco-car manufacturing and distribution in Thailand, offers both the five-door March hatchback and four-door Almera sedan.
The carmaker has sold 94,718 units to date _ 66,612 Marches and 28,106 Almeras.
The March was launched in early 2010 and the Almera late last year.
"Nissan remains firm and cooperative towards the Thai government's eco-car development project and is confident of maintaining its leadership in the eco-car market," said Takayuki Kimura, the president of Nissan Motor (Thailand).
Nissan's sales set a record 51,482 units in the first half of this year, up by 40% year-on-year.
The previous record was in the first half of 1996, when sales reached 50,126 units.
