The unveiling of the Z Proto was proof that Nissan was committed to the continuation of a legacy. A legacy that cemented the intentions of the Yokohama-based company to be a different kind of automaker. Different, as in showing a sporty side and making it their focus at a time when vehicles from Japan were attracting global customers in increasing numbers.
Ford also did a shrewd move on making Bronco its own "brand." I understand why, since the Bronco serves a completely different purpose within Ford’s sales infrastructure. Mustang has a similar standing within Ford, as they are being developed into their own "brand" with the coupes, convertibles, and the Mach-E electric crossover.
