It's hardly an earth shattering discovery. I had a 2019 Mini Cooper S and I parked it next to a 1960s Cooper S like the one I had back in the day. The owner of that and I compared the two. The current "Mini" is longer, wider, taller and of course far heavier - 635kg plays 1295kgs.
Just the seats in the newer car probably account for 50+kgs extra weight. Add in all the trim that the older car basically didn't have, the a/c and all the other gubbins probably accounts for 100kgs or more. And that's before we look at the relative strengths of the two basic bodyshells. Although the old Mini was one of the safest cars of its day (as long as you had a frontal accident) I would prefer to crash the modern car!
Of course, the modern Mini is far faster and far more economical despite lugging all that extra weight around. Not quite as much fun to drive though...
