BERLIN (Reuters) - Shares in some German automakers and suppliers were indicated lower in pre-market trade on Thursday after U.S. President Donald announced 25% tariffs on imported vehicles, a move that threatens to hurt Germany's already struggling auto industry.

Hildegard Müller, described the US decision to impose tariffs on cars as "a fatal signal for free, rules-based trade." This decision impacts a significant export market for German manufacturers at a time when they're grappling with declining profits.

In a further blow to Germany's struggling auto industry, US President Donald Trump has announced steep tariffs on foreign car imports and parts, provoking threats of retaliation from trading partners.
