[concours] Rational Class Basis

There’s been a lot of discussion about class splits and consolidations. One
factor hasn’t been covered very much which is critical in Champion Division
but negligible in Driven - that of the engine compartment and engine
technology.

For example, some have proposed splitting XJS by age or XJ6/8 (new style)
based on the 1995 X300 body redesign. In both cases, the proposals ignore
the most important factor in what distinguishes winners from losers in
these classes - engine compartment detailing. It ignores reality to believe
that a V12-powered car in similar overall condition and with a similar
amount of preparation can successfully compete (neglecting the MAJOR factor
of judging variation) with an AJ-6/16 powered variant in the same body
style. There’s simply far more than twice the stuff to work on and to find
fault with in the V12 and the V8 is still another completely different
story compared to the 6.

Going back in time, the same truth holds. A carbureted XJ6 is quite a
different animal to judge compared to its EFI brethren. In many ways, the
engine compartment is more like a Mark X. THAT story is complicated by the
presence of EFI and carbureted V12 variants.

In the REAL world, the outside shape of the body plays little role in a
car’s placing in a show. Deductions are almost universally made for
condition, along with the inevitable tire and wheel deducts which have
nothing to do with the car’s age. That is one reason inexperienced judges
are typically assigned to the exterior.

Things are a little less clear-cut in the interior, where authenticity
problems creep in on cars that have been freshened or restored, but
interior approaches often crossed across model lines and changed during
model runs. The XJS is a classic example of this. Same for the XJ Series
cars.

Anyway, what I’m suggesting is that any radical class consolidations should
be based on more than superficial similarities. V12 cars are truly unique
in Champion Division and perhaps there should be one (or more) V12 Classes
with all models containing V12s represented.

My proposal here is that a major consolidation is unlikely soon so if we do
it, do it right! That is one reason I numbered the classes in my “minor
change” post the way I did - it moves towards a consistent approach of
numbering classes - ie 2 is XK-engined sports, 3 is E-type, 4 is XK-engined
saloons, 5 is AJ6/16-engined saloons, 6 is XJS, and 7 is “new engines.”
Unfortunately, the minor mod ignores that a V12 IS different but it is a
step in that direction.

That’s why I mentioned that the modern saloons should be split when they
went to V8s not the X300 body style which still had the XJ40 interior
anyway.

You have a point on the V12 vs Xk.
