In British English, a trillion used to mean a million million million (i.e. 1,000,000,000,000,000,000). Nowadays, it's generally held to be equivalent to a million million (1,000,000,000,000), as it is in American English. Thus in British English there were a million billions in a trillion. Now the convention has become a thousand billion just like in American English.

And as with Ford, any manufacturing those companies keep in the United States will probably involve more expensive vehicles whose profit margins justify the higher labor costs of building them.
