A friend of mine once had a large old Cadillac which did this. It
was as I recall a straight 8 6 litre engine which had the option of
selection "ecomode" from the dashboard by switching to 4 or 6
cylinders which activated valve depressors. (
In true American car fashion the car had the handling of a barge and
a shiny front bench seat, so a seat belt was necessary not for crash
protection but to hold the driver in place when cornering. As
America doesn't have roundabouts I don't think the designer
considered corners to be important.
When using the ecomode with 4 valves selected the car would gradually
slow down if being driven on level roads so you had to adopt a
coast/burn technique. On gentle hills it would eventually come to a
stop if 6 cylinder mode was selected. There was no discernable
difference in fuel consumption between any of the modes but the
vibration in anything other than 8 cylinder mode made driving it a
different experience.
Heh, it didnt sound too healthy. I've driven such an engine, and it was
fine on less cylinders, though certainly not as smooth.
