Hmmm..

1968 Jaguar XJ6 4.2: weight 1537 kg.

2008 Jaguar XJ-R: 1659 kg.


Small problem there... The X308 steel predecessor to the X350 ally XJ was
about 200kg heavier than the X350.

After the "Series" XJs, which would have steadily put on weight from the
s1 you quote above, the late '80s/early '90s XJ40 was north of 1800kg.

Sure - but the XJ40 had most of the crash-resistance measures in place.
The OP's position was that crash protection couldn't add that much
weight..
