DETROIT (Reuters) - BMW AG Chief Executive Oliver Zipse said Wednesday he is weighing options for the company’s mobility services joint venture with Daimler AG, including bringing in new partners or possibly a partial sale. BMW wants to continue to participate in the mobility services market “whether we bring in new partners or whether we sell it,” Zipse told a videoconference of reporters. “This is a very dynamic environment,” he said. “You will see where we make one or the other move.” The future of Free Now, the BMW-Daimler venture that includes car sharing, ride hailing and other services, has been uncertain. Last month, Germany’s Manager Magazin reported Uber Technologies Ltd had offered 1 billion euros for the venture.
