The models which are sold in the UK are the Sandero hatchback, Sandero Stepway crossover and Logan MCV estate.
The most recognisable difference in each of the updated models is the adoption of a new headlight and grille design, which brings them in line with the Duster to present a unified Dacia family look.
New headlights, incorporating LED daytime running lights, form a pattern of four rectangles. Dacia intends for this to become its headlight signature across the range. Tail lights also have a similar rectangular theme. The bumpers have also been redesigned.
Although scant on details, Dacia promises that the interiors have also received updates to features, materials, ergonomics and storage areas.
It is not yet clear whether the updates will involve any new engine or gearbox choices, with the rest of the detail to be outlined when the new models are presented at the Paris motor show media day on 29 September.
