A source told Reuters on Tuesday that Continental was continuing to ponder all options for its future corporate structure and kept reviewing its combustion-engine business.

"As of today it is wide open, if and which changes could result from these early evaluations," Rolf Woller, head of investor relations said in a written statement after trading hours. "To date there are no plans which could be submitted for approval."

Bloomberg News had reported earlier in the day that the firm was in exploratory talks with advisers on a strategic revamp which could result in creating a holding company and listing its more profitable divisions or combining some operations with rivals.
