In the models charts, over the first 9 months of 2026, the BMW X1 (+3.1%) is in the lead with a dominant 3.6% share, distancing the Dacia Sandero (-12.8%) disappointing at 2.2%. The hero of the period is the new BMW iX3 at #3 and 2% share vs. #11 and 1.3% over H1. In fact, over Q3 the iX3 edges past the X1 to hold the overall pole position at 3,439 sales vs. 3,438… The Tesla Model Y (+42.4%) stays in 4th place while the Mini Cooper is down to #5.
