I noticed the same thing, it is weird but minus the passengers in the back that are usually around 100 to 200 pounds(3 ppl for a sedan/wagon and 2 for a coupe/convertable) and a full tank of gas. That's where most of the weight comes from is the rear seats from passengers that's why it seems soo unbalanced imo. I am planning to do a little research on it as well lmk if you figure something new out.
