Subject: yet another engine choice - VW "twincharger" HOLD IT!!

When are we going to learn to get off the HP drug habit? Here we are at
$3/gal. (and increasing) gasoline in the US and yet we eat up V8 engines in
'06 Chevy Impala's and 170HP Twin-Charger diesel VW's! I have a 2005.5
Jetta with the 1.9L PD engine that gets 47 MPG overall during the past 3800
miles, at 100 HP in a sedan that holds 5 people. There are all sorts of
people on this list that have gone through the pain and agony of installing
TDI engines with and without the electronic controls in their Vanagon's to
get better than 17 MPG from the stock motors. I thought the race for HP
went away during the first oil embargo in the 70's? Supply & demand are at
our heals now and those with large engines that get under 32 MPG are costing
all of us more to fill up our vehicles with gas or diesel. Am I off base by
suggesting we wake up and start thinking globally and act locally? I was
told that in the early 80's and bought my first VW (Rabbit Diesel LS). I
haven't had a V8 (or an 'American' car since) and never will! I'm doing my
part to keep your fuel costs down through reduced demand. What are you
doing to keep my fuel cost down? And that of the rest of us? It might be
nice to own a Twin-Charger in a Golf for fun. It does not make sense as a
commuter vehicle, or for long trips. IMHO.

VW in my blood!
