With the recent successes of diesel engine, it would be highly beneficial for Ford to start taking a serious look at diesel powered sedans and coupes. Though Ford has done an outstanding job utilizing twin-turbochargers and other means to gain efficiency with gasoline, diesel seems like a solid addition to the lineup. Now hydrogen. I was lucky enough to participate in a BMW Hydrogen drive where I was allowed to drive the 7 series with Hydrogen/Gasoline engine. It was unbelievable and that was nearly 4 years ago. I can only imagine where this technology is today. I would love to see a partnership with BMW in bringing hydrogen to the states.
