A highly-anticipated announcement at the US's premiere auto show in the Motor City was called off late Monday, and the two sides planned a conference call with reporters instead for the following morning.

"We don't have enough details yet to go out in front of more than 500 journalists, so we decided to call it off," Ford spokesman Mark Truby told AFP.
