Ford has been producing good diesels in Europe for years. They own Volvo who engineered a superb 2.2 TDI engine that they put in their Mondeo - I have the same engine in my Jaguar estate. It's over 150PS and I regularly get over 50mpg. It's quiet and smooth with incredible torque - 400Nm at about 2500rpm.
Ford have left it too late to produce the engines in North America as they can't afford to build a new engine plant. I think we'll see the demise of Ford soon unless they start behaving in a more agile and innovative way.
