Edmunds calculates maintenance in the True Cost to Own.
 
Just comparing some '06 Jetta's against each other, I don't see any advantage.
 
TDI 4dr Sedan w/Manual
Average Cost per Mile* $0.50

2.0T 4dr Sedan w/Manual
Average Cost per Mile* $0.50
link
 
2.5 4dr Sedan w/Manual
Average Cost per Mile* $0.45
link
 
* This is a 5-year estimate (based on 15,000 miles per year). The automatic styles seem to be a penny or so cheaper to own and operate.

Is it the environmentalists trying to keep this "dirty" fuel out of our hands?
 
No it is the Dirty Environmentalist in the government on the payroll of the oil companies.
Gas is the byproduct in the refining process they want to get rid of. Diesel will be in short supply until they add more refining capacity. With a glut of gas there is no real urgency to sell more diesel.

I think this is a common red herring but it's not a "problem" for an engine designed to run at higher rpms to do so. It may be a problem for you as a driver but it's not a design issue. Otherwise Honda would have folded decades ago.

No, the issue was smoothness and a nice ride. If the engine has to rev to get its power, then that means it needs many gears(problem prone and expensive to fix mega-speed automatic) or has to rev to where most Americans think it's noisy.
 
A modern turbo-diesel is quiet, refined, shifts less, and generally is better in traffic and normal daily driving. They have done great things with the technology in Europe and it's nothing like what Americans remember. Though, to be honest, I love the sound of an old 4 cylinder 1970s Mercedes diesel... Like a small tractor and just as anti-yuppie at the same time...

Everything I see in all the reviews says that 6 and 7 speed transmissions are a feature, not a bug.

My initial impression of the Mercedes 7 speed in the GL320 CDI I drove was negative. I did not like the way it downshifted when I let off the accelerator. I like to feel more like I am coasting and not using the engine to slow me down. If I am going down a steep hill I prefer to downshift myself to use the engine braking feature. I plan to drive another Mercedes diesel after I test drive the X5 diesel. Maybe I will get around to it next week.

Thanks for the FYI. I will be sure to pose the question when I test drive the BMW 335 D for the second time. On the 2009 BMW 335D accelerator let off (6 speed automatic triptronic) I did not feel the slight engine braking the 5 speed manual VW Jetta gives.
 
On the VW (03 5 speed manual anyway) as most folks probably do not know, the system is a so called "drive by wire" system. One spin off: a coasting or no fuel draw situation, does NOT have the engine compression of older diesels. It does result in better overall mpg due to no fuel draw conditions (on longer grade descents). I would imagine the same is true for automatics (to a lesser degree)

I am not sure what the labeling "common red herring" you are referring, but I agree with Plekto. I do so comparing the Honda, Corvette and Jetta TDI. How the 2009 BMW 335 D with 425 # ft of torque accelerates, FULLY illustrates what Pletko is saying. The TDI vs gassers does also but at 155 # ft of torque is not as dramatic as 425 # ft of torque.

It is amazing how that varies. In my little WI town, when I last filled up, RUG was $1.80 and premium diesel was $2.19. Your difference is $1.10 and ours is 39 cents. And WI has the second highest state fuel tax in the nation.

Gary,
 
Thanks for your response. Here's some follow up questions:
 
 Doesn't diesel fuel come first in the refining process. Doesn't it take another step in the refining process to obtain our gasoline? If so, why is diesel more expensive?
 
If 80% of Europe's passenger cars are diesels doesn't that indicate that diesel is pretty efficient? Those folks pay huge taxes on their fuel so they are hyper sensitive to price.
 
Is there still an environmental downside to diesel that I'm missing?
 
Bob
