If the car is assembled in Russia, this is Renault Logan. Dacia Solenza is assembled in Rumania and Ukraine. At the first glance they are twins, but as I understand, the used platforms are different. However, 1.4 l engine is the same, just slightly different torque. Actual engine choice at Logan is wider and depends on market. If I am not mistaken Russian Logan may be equipped with 1.6 l engine too. On other markets there are also more powerful version of gas engine and a diesel.
