General Motors or Chevrolet?

General Motors have taken a full page ad in the newspapers to convince the world that their Indian operations are going strong, no reason to doubt their solvency, yada yada. If you look at the ad, you will find exactly one mention of 'General Motors': the line below the CEO's name and designation (well, two if you count the GM logo in a picture of one of their factories). It's 'Chevrolet' everywhere else: it's almost like they want to dissociate themselves from the G-word -- which is sort of schizophrenic, considering the intent of the ad.
