Stupid question (not a native speaker) but I read that prototype race cars hold different class names according to the regulations of the series in which they race (e.g Can-Am) but are essentially called 'prototypes'.

The definition of a prototype is an early form of a vehicle from which other forms are developed. Reading this definition I think of camoflaged production cars being tested on the road/track.

Racing prototypes are categorized as 'purpose-built race cars', but why call them 'prototypes'? Is it because they're in continuous improvement with no final form or what?
