The A36 and a57 steel for the new Tesla Model X are expected to be made in China and are said to be about 50 percent and 60 percent lighter than the previous steel used in Tesla’s cars, The Wall Street Journal reported.
The new materials will also allow the new cars to go faster, with the A36 coming in at 0.9 seconds to 0.8 seconds faster than the A56.
A Tesla spokesperson confirmed to Polygon that these new materials are not part of the upcoming Model 3.
The company previously confirmed that the new A36 steel used for the Model 3 will be manufactured in the U.S. The A56 is a carbon composite steel that is also produced in the United States.
Tesla did not respond to requests for comment on the report.
The production of A36 is a significant change from the company’s previous efforts to build high-strength steel, the WSJ said.
The WSJ added that it has been in discussions with Tesla about manufacturing of the material.
