Volkswagen AG’s Audi won’t increase prices in the US in July after its sales there nosedived in the second quarter.

The German brand’s deliveries in the lucrative market fell 19% in the three months through June, the sixth consecutive quarterly decline there. Audi cited a challenging economic environment as well as model changeovers for the drop.

President Donald Trump’s tariff moves have raised costs for Germany’s export-oriented automakers. Like Porsche AG, Audi has no factory in the US, and its top-selling Q5 sport utility vehicle there is imported from Mexico. Sales of the model slumped 29% in the second quarter.

Audi is currently weighing to start local production in the US, and in May said it will choose a site this year. Chief Financial Officer Jürgen Rittersberger at the time said the automaker is evaluating potential production synergies with Volkswagen’s Scout brand and an existing VW factory in Tennessee.

German manufacturers like Audi, Mercedes-Benz Group AG and BMW AG are under pressure to protect sales in the US amid waning demand in China, where local brands led by BYD Co. are wooing customers with lower prices and sophisticated in-car technology.
