Dacia models sold outside of Europe use the Renault logo. In Europe and North Africa Dacia is a well established name with a strong following. Sales were up 6% in 2016 and 12% in 2017. The range is based around five models as listed below.
The small Sandero hatchback model is the most popular, with just over 40% of all sales. The Duster SUV didn't keep pace with total sales but still accounted for over a quarter of them. The Dokker leisure activity vehicle and panel van range is on the up but the Logan 4-door / wagon variant of the Sandero is not doing quite as well for the brand at the moment. Finally the Lodgy MPV is growing nicely, albeit on low numbers.
I have no idea how far Renault wants to spread the Dacia brand. In Europe, Renault takes the middle ground mainstream route and Dacia the budget road. In emerging nations Renault uses Dacia models and is therefore the budget brand. If these models are to be introduced into mature car markets elsewhere around the world, one would assume the Daicia brand would be used in the same way as it is in Europe. For now that doesn't seem to be a priority.
