In the August issue of Collectible Automobile there is an article on
the '61 Continental that goes into the background and evolution of the
design, and they show a few illustrations of the Thunderbird concept
that Elwood Engel created, which later became the basis (in part) for
the 1964 Imperial.
In the illustrations, particularly the side view, you can really see
the styling themes later used in the Imperial. In some photographs of
other mock-ups, you can also see some "Engel-esque" things that were
never used on the Continental or Imperial but showed up later on other
Chrysler products, such as the rear end of the turbine car and the
taillights of the '68 300 (#67 bulbs, no doubt).
It's amazing to me that a guy could have an idea in 1958 or '59 and
keep it kicking around in his head for 10 years until he's finally able
to execute it.
It's also interesting to learn that Robert McNamara, later Sec. of
Defense, nearly killed the Lincoln completely. If he had succeeded,
that would have meant Lincoln would have vanished in 1961 and Cadillac
and Imperial would be left to battle it out for supremacy of the luxury
car market. Just imagine it, Star Trek fans, an alternate universe
where Imperial is made #2 overnight and later rises to #1!
In that universe, there would be no IML! There would be no need for
one. People who owned old Cadillacs would pull into gas stations and
folks would say "For that much money, you could've bought an Imperial!"
The mind reels. Any time travelers out there want to go back & change
McNamara's mind?
