Great question and an important one as it relates to automotive especially. Content is the only way you are going to get non-branded keyword growth for your domain and a backlink or two.
Blog posts, or research pages, are great ways to build on your internal linking as well in order to move that juice and authority around your site.
That brings a better average position, higher chance of appearing in AI output, which continues to build on the non-branded growth, etc, etc.
Google will not penalize for AI content. (I encourage the use of AI for brainstorming, outlines, mind maps and content refreshing)
However, content "at scale" is going to raise a flag, which is something that has always raised the red flag for Google.
For any dealer looking to add content via a blog, or otherwise, my advice is to make sure you have a structured series of content, steer away from content that singles out the YEAR of a model (unless it's a brand new release) and always, always add internal links + a lead form at the bottom.
You just never know when you are going to log into Clarity and watch a user with informational intent fill out a form on your site.
