Here's a quote I have from an Australian owner:

!  The block is the biggest V8 ever made.  It was made in 4 capacites. By 1980
!  the fuel crisis resulted in a small bore with mine having a capacity of only
!  6036cc.  Previous versions were 7.0, 7.7, and 8.2 liters.
!  With the 'modulated displacement' function operating I should be getting
!  mileage of 16 l/100km around town, instead of the 22.4 I am now obtaining.

16 l/100k is (16 l = 4.23 US g, 100 k = 62.1 m) = 14.7 mpg (US), but the
22.4 figure is 10.5 mpg (US). Fuel economy was percieved as a real issue 
back in 1980.
