Dacia chief executive Nicolas Maure has said the brand could grow capacity by 150,000 extra units a year globally pushing volume by 15% to 1.15 billion.
Dacia registered 17,146 units in the UK last year. The brand saw a 245% increase in registrations in Q1 this year from 1,978 units in Q1 2013 to 6,821 in Q1 2014.
Maure said: “We have some more capacity in and also in the rest of the world: India, Brazil and Russia. We also have CKD (completely knocked down) production starting in Algeria in 2014.
"Then we have to look at the model mix. We are increasing Duster capacity . And we could add shifts in Romania to maybe four or five."
Dacia's annual sales have risen from around 80,000 a year, mostly in the Romanian domestic market, when Renault took over, to more than a million spread across four continents in 2013.
But the Dacia name is known only in Europe and around the Mediterranean rim. Elsewhere the cars are badged as Renaults.
Renault began to take control of Dacia in 1999, first with a 51% stake which has since risen to 99.3%.
