Except you wouldnt do that for the sake of your engine would you, poor
thing accelerating hard when cold!

Agreed, modern common rails are amazing little creations. Mind you I
manage to average 45 from a carb'd petrol engined small car that is 17
years old so you'd have hoped they could have got a little more out by
now :)

When cold the Prius engine speed doesn't change noticeably on even fairly
strong acceleration, like we do going up the hill from our house - that is
done by the electrics. The engine continues to do its warm-up process at
about 1200-1500 rpm. Of course, you wouldn't want to take any present day
car right onto the freeway when cold, that would stress the engine. In a
serial hybrid (not available in production today) it wouldn't matter at all.

What you save in fuel mileage you loose when it breaks, and parts are
needed( more expensive) also fuel filters and maintenance cost are another
looser, Diesel fuel is more expensive than gasoline in today's market, in
the winter you need blended fuel or worse #1 that's probably going to cost
$.75 a gal this winter, or expensive additives that keep the fuel from
gelling.I have owned 2 diesel and there great for mileage but when it breaks
no matter what it is, it cost more!
