German carmakers are experiencing a significant decline in sales in China, with some reporting their steepest drops in years. The extent of the decline varies, with some outlets reporting sales plunges of 30-41% in the second quarter, while others note that certain carmakers have suffered their worst sales drops in over a decade. The cause of the decline is not entirely clear, with increased competition cited as one possible factor, although the impact on the broader Chinese car industry is uncertain.
