When you have seven brands under one roof, it is going to be difficult to have brand separation, especially when some of these brands had formerly been in direct competition with each other.
Radical is a technologically advanced company using cutting edge stuff, and that is exactly what Track was marketed as for quite a while.
Ebonite was the flagship of the fleet, which is what Brunswick always was as well.
DV8 is edgy, and aimed at the young, hip demographic, which is where Columbia300 seems like it was heading to. Bright, brash and bold colors, young generation staffers, and “in your face†attitude marketing.
Hammer, I believe, is one that could actually stand alone if it had to. It seems to have a following strong enough, and enough panache and attitude, that it could probably make it as a freestanding brand (think Motiv).
Seven brands is a lot, especially when all seven are in the same business. That’s exactly why GM did away with Pontiac and Oldsmobile. They competed directly with Chevrolet and Buick respectively, without enough market share to go around.
Brunswick may, eventually, shut something off, but I think it would only be after they cemented that customer market share to one of their “alternate†brands.
