Cars aren't usually released January 1st, if you release a car halfway through the year and named it for that year it would be outdated pretty quick as far as the model year goes. And that's another thing, there is a "model year" just like a "fiscal year". They don't necessarily start or end at the beginning or end of the year. Usually the model year is whatever year the car will be discontinued in, so if a car will be sold from mid 2012 to about mid 2013, it's a 2013 model.
