No car sales data available for Belarus, but the observation of Belarusian streets through recent YouTube videos show a structure very distinct from Russia and more alike neighbours Latvia and Lithuania: Lada has completely lost its grip on the Belarusian car market which appears to be very fragmented with a few models standing out slightly.
In this context, the Toyota Corolla, Kia Cee’d, Ford Fusion and Toyota Camry seem to be among the most successful cars in Belarus, with the Ford Focus, VW Golf and Passat, and Opel Insignia also worth mentioning.

As far as older models are concerned, we can see a lot of Peugeot 206, Audi A4, Citroen Xsara Picasso, Chrysler Voyager, VW Sharan, Toyota Avensis and Renault Scenic. Belarusians are very fond of station wagons too.
This speculation is solely based on the observation of recent YouTube videos of the streets of Minsk and a couple of other Belarusian cities. If you know more about the Belarusian car market, please make sure to get in touch!
