Volkswagen will propose to U.S. authorities a new catalytic converter system that could be fitted to about 430,000 cars capable of cheating diesel emissions tests, Chief Executive Matthias Mueller said on Sunday.
"We have one (catalytic converter) in the works and we believe that that will be a part of the technical solutions," Mueller told reporters at a VW event on the eve of the Detroit auto show.
Asked whether he expects the new catalytic converter to bring 430,000 rigged U.S. cars into line with emissions standards, the CEO replied: "Yes, we believe that this is possible."
Mueller is meeting U.S. Environmental Protection Agency (EPA) administrator Gina McCarthy on Wednesday, where he plans to make his proposal.
Mueller expressed optimism that VW and the EPA would be able to bridge their differences. McCarthy has previously bemoaned that both sides have failed to develop "a satisfactory way forward" despite months of talks.
"I think we can now offer a package that will come very close to what the EPA is expecting from us," the CEO said.
