context_page_description: Automotive superlatives include attributes such as the smallest, largest, fastest, lightest, best-selling, and so on.
  This list is limited to automobiles built after World War II, and lists superlatives for earlier vehicles separately. The list is also limited to production road cars that:
  Are constructed principally for retail sale to consumers for personal use transporting people on public roads. No commercial or industrial vehicles are included
  Have had 25 or more instances made by the original vehicle manufacturer offered for sale to the public in new condition
  Are street-legal in their intended markets and capable of passing any official tests or inspections required to be granted this status
  Calendar years rather than "model years" are used except when explicitly marked as otherwise.
