The judges are an international panel of automotive journalists. In that time, 247 overall and category titles were bestowed on 18 manufacturers, or in some cases combinations of them. Here we list those companies in ascending order of how many awards they received, ending with one which spectacularly gained just over a quarter of the total.

(Note that we are counting only engines used in production cars. In the early days, three concepts also won awards, but these will be mentioned only in passing, if at all.)
