I know that diesels are very reliable and don't have the stigma they once did. But even with the mileage, the cost of diesel seems like it would offset any gains there. I could be wrong and I don't have the research to back it up.
I think part of it is that people like them, I like them and was quite impressed with the power delivery - for an economy choice.
Let's do an estimated fuel cost exercise:
You decide the jetta is the car for you. Now which engine?
- 2.0T epa 24/32 FUN
- 2.5 epa 22/30 BLECH
- TDi 29/40 kewl
Since this is my exercise I'm going to discard the 2.5 5cylinder because it is a raspy dog disappointment of an engine that I would not buy - and real world doesn't do much better than 25mpg on the highway. The 2.0t gets close or better than epa, the TDi typically gets better, but we'll stick with epa estimates.
If I rock the 2.0T, I'll put premium in it every time - as I do my MS3.
Current prices near me:
$4.17/gallon for 93 octane goodness
$4.85/gallon for diesel
10 gallons exercise
4.17 * 10g = 41.70
4.85 * 10g = 48.50
Range
2.0t city = 240 miles; cost per mile ~ 17.375 cents
2.0t hwy = 320 miles; cost per mile ~ 13.031 cents
TDi city = 290 miles; cost per mile ~ 16.724 cents
TDi hwy = 400 miles cost per mile ~ 12.125 cents
12,000 miles fuel cost
2.0t city = $2085.00
2.0t hwy = $1563.72
TDi city = $2006.88
TDi hwy = $1455.00
Conclusion:
Even with the high cost of diesel fuel, the TDi is the more frugal choice than the 2.0t. You can save money and contribute to society by using less fuel.
Opinion:
It's not worth the minor cost difference from an enthusiast standpoint. Less than $100 a year difference for an average number of miles. If this is a family/wife car, then choose the TDi + DSG. On the other hand, it could be interesting to play with diesel, mod it, experiment with bio mixtures, etc. I would rock the TDi at autocross and maybe even some track days.
Yeah sorry I was bored
