Definitely not Porsche related, but we're thinking of buying Cindy a Dodge Magnum wagon. Hopefully a year away, to give MOPAR time to work out any new model bugs. Evidently, it's optional V-8 comes with a "multiple displacement" feature. Thus cuts off 4 cyclinders when in cruise mode, supposedly giving a 20% boost in fuel economy. Okay, so you kill the fuel intake and spark to 4 cylinders? Wouldn't this move make for more wear in those cylinders?
How does this work? Any engine guys care to give me their thoughts on this????
