Streiff, who is also chief executive of PSA Peugeot Citroen, made the comments at a news conference following a conference at the European Commission in Brussels.
The ACEA said the conclusion of the conference had been to call for a supportive framework from the EU to secure the auto industry’s future.
The ACEA said a supportive framework should consist of four pillars: better regulation, reciprocal trade relations, a low-interest loans package and market incentives.
