That's a hallmark of just about all of the current generation of the
common rail engines (see VW TDI, Mercedes Bluetec). Level of
sophistication varies a lot of course; the TDI has been around for
almost a decade so you wouldn't expect it to be quite as awesome as
the Bluetec which is just now starting its day in the sun. Indeed,
things have come a long way since my 1980 Rabbit Diesel.
So here's the Big Question: why aren't we getting these with the Smart
ForTwos that are coming in next year? This is the *only* car that has
gotten me even the least bit excited in recent years (I've borrowed
one in Europe - I actually *fit* height wise which is no mean feat for
a tiny car and simply not doable in, for instance, a Prius.
Can't be that hard to get one past the EPA...

this is just cool.

Even the current versions of the venerable Cummins B are pretty
sophisticated these days.
