Neil, I don't understand your point or why you placed motorsport in quotes. The connector in the photograph is manufactured by Deutsch. It's one of their AS (autosport) Series products. Motorsport and autosport are interchangeable marketing terms with respect to describing a connector (i.e., they are minimally more compact and lighter than a mil-spec connector).
I use Deutsch connectors wherever possible. AS Series for critical connections, bulkhead connections or where I need a high pin count and the DT series for everything else.
