The X1/X2 was BMW’s best-selling model series, followed closely by the 3 Series/4 Series. BMW rose in Europe and the United States in the first half of 2026, but it wasn’t enough to offset its continued downfall in China. The X3/iX3 Are BMW’s Stars So Far This YearAs you can tell, BMW still doesn’t provide a proper breakdown for each model series when it posts global sales results, choosing instead to bundle two related lineups together. While a direct successor isn’t planned, much like a new 8 Series Convertible isn’t happening, BMW isn’t abandoning this niche. We won’t know until 2027 or even 2028 whether ALPINA’s sales will be bundled with those of the BMW-badged 7 Series.
