I'm sure I've heard it called houndstooth a few times and I thought that's what it was called. I'm thinking it just a generic name some use.
I admit I've never really never paid attention, as the pattern, white and cloth car seats isn't my cup of tea. I build engines, some would say obsessive about them, but honestly that obsession has never carried over to the difference in years, options or the brand of nut on a hood latch and the exact way it was clocked from the factory.
I'd be a poor choice as a concours judge, but I'm OK with that.
