Chrysler Naming Fun

Rumour has it that the Chrysler Sebring midsized mediocrity will be renamed the 200C when relaunched under Fiat rule.  This is funny because the 300 is a large car, and the upcoming 500 will be a very small car.  

Chrysler clearly needs a consistent naming convention, and as an engineer I am ready to help.

Chrysler cars should be named in terms of 1/(size).  Therefore, since the 300C is a large car, and the 500 will be a very small one, the car-formerly-known-as-Sebring should be named the 400.
