Audi is considering building its first U.S. auto factory, likely somewhere in the South, according to The Wall Street Journal.

Gernot Döllner, Audi’s chief executive, told the newspaper that the carmaker was moving “full throttle” toward a final decision.

The plant would likely be located near one of parent company Volkswagen’s plants. The automaker has a factory in Chattanooga.

And should the Trump Administration continue with a 25% tariff on imported automobiles, the company could build Audis in Chattanoooga in the short-term, he said.

Audi has a plant in Mexico and has exported its Audi Q5 SUV to the U.S.

Volkswagen has also started building a plant in Blythewood, S.C., to build Scout vehicles.

However, building a new plant could take around four years. Döllner said the South makes sense as a destination as there are already auto suppliers in the region.

A decision on the plant—including its location, if the decision is to go ahead—will be made this year, he said.

About 53,000 Alabamians are directly employed in the auto industry, according to the Bureau of Labor Statistics. The state is home to manufacturing plants by Mercedes-Benz, Honda, Hyundai, and a joint manufacturing facility by Toyota and Mazda.
