"An all-new platform was considered, and there was talk of moving to the CD6 platform being used for the Ford Explorer".
"The new coupe rides on the same platform and uses the same engines (all with slight modifications), meaning that the new Mustang will, in all likelihood, drive similarly to the outgoing model"
I remember reading a while back that the SUV platform was considered. I wondered at the time if that meant lots of extra weight?
Supposedly, cost entered into the decisions also.
