I’m working on a new series of posts about automotive weight gain over the last 20 years, for vehicles sold in the USA. In the beginning, the focus will be on raw numbers rather than reasons why or if HP increased to keep up. First post will be mainstream compact sedans nameplates that have been in constant production since at least 1997. I hope to have it up Friday, but each one of these graphics is taking me entirely too long to put together, so it might slip into next week. I enjoy it, though, because I enjoy tinkering with graphs and pictures of cars. Surprisingly (to me anyway), there were only 6 non-premium compact sedan names going back that far. Once we get a few of these together, we can start to look at how different classes compare and focus on specific models for further scrutiny.
