I recently drove a Volvo 850 Turbo for a week.  It had an onboard computer
that would indicate the fuel consuption in litres/100 kms.  For those of
you not familiar with measuring fuel comsumption in l/100kms, the lower the
number the better the fuel economy (this is the opposite of measuring mpgs).

I was shocked at how high the fuel consumption went on normal acceleration
(30-35) and on aggressive acceleration the numbers went higher still
(40-50) but when coasting to a stop, especially on a slight downhill grade,
in a high gear (4th or 5th) the numbers went near zero (1-5).  The overall
rate of fuel consumption, after a week of "spirited" city driving, for this
vehicle is about 14 litres/100kms (about the same as my Westy).

The bottom line, disengaging the motor would seem to save very little and
could cause extra wear and tear.  *** Warning *** This is MHO and I don't
know anything (that's what people tell me) :-)
