[Vwdiesel] Lusting after efficiency

[Tad]

Doyt, interesting you don't mention it by name, but we have one too, and
it's a good car.  Quite different from a VW diesel, but good in it's own
way, and basically equivalent MPG.

As for the diesel hybrid... I think there's a good reason we haven't seen
one of those on the market.  For one, diesel wouldn't gain as much from the
start/stop technology because it's far more efficient at idle.  Two, I
suspect longevity issues from the stop/start due to, among other things,
issues with keeping the system up to temp (which is hard enough in cold
weather with a conventional diesel).  Third- cost.  The additional cost of
a diesel plus the additional cost of a hybrid setup is a double-whammy.

It makes me curious  though, is there such thing as a miller-cycle diesel?
