In Formula One racing the terms "constructor" and "entrant" do not mean the same thing. A "constructor" builds a car or engine. An "entrant" is the person or corporate entity that enters a race. They register a car and driver with the FIA. They are responsible for making the car ready to race, and keeping the car in good condition during the race weekend. Because of the role and activity of the entrant, the term "team" is often used when talking about an entrant.
