What I'm about to say sounds outlandish, and to the best of my knowledge, no one at either of the companies involved has seriously considered such an idea. Still, this is something that should happen. With nearly the entire automotive industry marching toward electric vehicles, Ford should seriously consider buying Tesla.
For a decade, Tesla has failed to make a profit from producing a high-quality, mass-market vehicle. The carmaker has yet to build the first-rate supplier network it desperately needs to make the numbers work, because it takes more than a mere decade to complete the impossibly complex supply chain that established manufacturers enjoy. The only companies qualified to help Tesla overcome this gap in both quality and cost right now are those established manufacturers, and of the potential suitors, Ford would benefit the most.
