[Vwdiesel] Honda diesel MPGs

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