Automakers including General Motors Co. and Hyundai Motor Co. reported a jump in US auto sales as the threat of price hikes from President Donald Trump’s tariffs drove consumers to showrooms.

GM’s deliveries soared 17% in the first quarter, with a 15% gain in retail volume, the company said Tuesday. Ford Motor Co. saw retail sales rise while Toyota Motor Corp. also reported slight growth in the first three months of the year.

Researchers including Edmunds and Cox Automotive had predicted volumes likely got a boost from anxious shoppers trying to get ahead of higher prices stemming from new US tariffs on imported vehicles, which go into effect this week.
