[W126 Coupe] V12 SEC

[Satish Tummala]

There is a 55lb difference between the 117 and the V12 motor.  There is a
13.5 lb difference between the 117 and the 119 motor.  The weight of the
two additional camshafts and valves makes up most of that difference.  The
valve covers and block are actually lighter in the 119 than the
117....perhaps the use of different/newer alloys?

The battery gets moved to the trunk in the V12 conversion helping to
offset some of the weight.  I haven't weighed the car as of yet.  However,
it does sit exactly where it did before with the other engines in it.

Remember that cars with V12s typically had ADS adaptive suspension
systems, a lot more optional equipment, like rear A/C, etc.  That makes up
lots of weight also.
