[Vwdiesel] Honda diesel MPGs

[David Cook]

Hey Arnie-

All good and valid points.  

That video, when givng the mileage, didn't say for
sure what car that the engine was installed in.  It
did mention the Civic a couple times, so I'll assume
that is their intention.

I'd say that a Civic would probably be the most
comparable to a Jetta.

I guess I stand kind of corrected too...

I just called the dealership, and the new Jettas are
rated at 42 MPG highway (I think that was w/auto), the
last generation was 46 auto, 49 manual.  (According to
the salesman.)  He mentioned that the newest engine
was rated at 10 hp more.

So, comparing a new Honda to a new Jetta, the mileage
is in fact very similar.

Also, I'm guessing that VW has some claim on "TDI" 
The Honda video kept referring to it as a "CTDi".  I
understand that Turbo Direct Injection can refer to
more than one type of engine.

I'd be interested in how the euro TDI engines do for
mileage.  I know they make more power (partially)
because they are able to take advantage of the higher
quality fuel mandated by european laws.

I guess in reality I was a little disappointed because
I was expecting the mileage to work out to something
like 100 MPG like that special test car they're
working on.

That and I do like VWs more than Hondas, even before I
discovered diesel!  ;-)
