On Monday a typically upbeat Ford boss Alan Mulally told the assembled industrial bosses of the CBI how he’d had to announce $17bn of losses (or negative earnings, as they probably call them) in his first week in the job in 2006, and how he’d had been able to announce a profit this year, thanks to significant streamlining, hard work and leadership.

He reminded (or, in some cases, explained to) them how the Ford Fiesta shared around two thirds of its components across all its global variants, and how the new Focus, the fruit of Ford’s one car strategy, would have 80 per cent common components around the world.
