I just checked the user reports from the EPA web site: http://www.fueleconomy.gov/
 
51.6 MPG - 46 vehicles - 2010 Prius
40.3 MPG - 24 vehicles - 2009 Jetta TDI auto
40.2 MPG - 16 vehicles - 2009 Jetta TDI manual
37.3 MPG - 13 vehicles - 2009 Jetta SportWagon TDI auto
 
Lowest / Highest user reports:
 
38/63 - 2010 Prius
34/50 - Jetta TDI auto
33/57 - Jetta TDI manual
28/46 - Jetta SportWagon TDI auto
 
Weird, even the owners of these vehicles are showing a strange MPG bias towards the 2010 Prius. As for pollution, I guess I don't care since my car is at home in Huntsville AL. I don't live in Japan, China, Korea, Mexico, Europe, Canada or any other foreign place. I'd recommend asking those folks if they care about manufacturing pollution ... any of them around this forum today?

Bob Wilson has a news flash for everyone - the Prius gets better combined mileage than a Golf. Stop the presses.
 
All Prius guys listen up for just a second as I break it down for you:
 
The Prius DOES get better gas mileage than the tdi.
The Prius DOES release fewer harmful emissions than the tdi.
 
BUT............the tdi is still better than 98% of cars on the road today at both of these key issues ---------AND it is a blast to drive. Can you all admit that this is a good combination of attributes? Can you understand why a person would find this car a really great all-around automobile worthy of one's hard earned coin? Shock me and do it.

I am glad you went to all that trouble. You have pointed out the fallacy of the EPA fuel economy ratings. Many of US including VW corporate have complained that the new calculations are very accurate for the hybrids and out in left field for the diesel cars. As your little exercise graphically points out. The average VW Jetta TDI owner gets about 19% better overall mileage than the EPA estimates. While the Prius is within 3% of the EPA rating. Which gives Toyota a leg up on sales of the Prius to buyers that would cross shop. As they will believe the EPA estimates. Hopefully the EPA gets it right someday. Not holding my breath.
 
PS
I would give up more than 10 MPG for the added braking, safety and handling the VW TDIs offer.

The Toyota closer to the 2009 Jetta TDI is really the 2009 Camry hybrid (and the Camry hp and performance wise Jetta TDI's torque drawfs the hybrids by 71%, 236# ft to 138 # ft).
 
www.fueleconomy.gov
 
2009 Jetta TDI EPA 29 C / 40 H / 37 mpg comb
 
2009 Camry Hybrid EPA 33 C / 34 H/ 34 mpg comb
 
"MPG Est For Drivers Like You"
 
 is more like:
 
2009 Jetta TDI 34 C / 50 H / comb 40.3 mpg
 
2009 Camry Hybrid 31 C / 41 H / comb 36.7 mpg
 
So Jetta TDI has 9.8% combined better mpg.
 
If one drives primarily H, Jetta is 22% better than Camry Hybrid
 
If one drives primarily C (surprise surprise) Jetta TDI is 9.6 % better
 
The Jetta TDI costs $2,390 less MSRP and $1,327 INVOICE less than the Camry Hybrid.The Hybrid's T or typical option package adds $1,150 MSRP/ $989 INVOICE

I have read the 2010 Golf TDI will start to hit the show rooms anywhere from Dec 2009 to Jan 2010. Edmunds.com does not yet list the pricing.

First, this is a discussion about two hatchbacks: the Golf TDI and Prius. Not the Jetta. Not the Camry.
 
Second, the Camry is a mid-sized car in every sense of the word, especially in length and interior room. The Jetta is a compact car in length and interior room.
 
Third, why do you (and others) continually forget about a major part of the Prius' and TCH's powertrain: the electric motors? You only talk about the power and torque of the ICE part of their powertrains. That is like talking about the power and torque of the TDI, but only the diesel part--forget about the turbo and forget about DI.
 
If you want to compare the Jetta TDI to the TCH (maybe because a comparison to the Prius is less favorable to the Jetta?), it's easy to create a discussion for that if there isn't one already.

NO, as I said before, the reality is the hp power match ups for the TDI and Camry Hybrid are closer. Indeed if you want to compare engine size and mpg the 2010/2011 VW TDI Polo are more matched. However the mpg is 71 vs 50 for the Prius. So the last real year of comparison would be the 2003 model year. Again the www.fueleconomy.gov shows them to be neck and neck mpg wise.

If you insist...
 
TCH Hybrid System Net Power: 187 hp
TCH Hybrid System Net Torque: 138 lb-ft + 199 lb-ft from 0-1500 RPM
 
So power between TDI and Camry isn't even close, and on starting from rest (when you really need max torque), the torque isn't close either.
 
But they are pretty close on the TDI vs. Prius:
 
Prius Hybrid System Net Power: 134 hp
Prius Hybrid System Torque: 105 lb-ft + 153 lb-ft

That is true only if you are a stop light drag racer. I need the torque when I have to kick it from 50 to 75 going up a long grade to pass a slow truck or Prius. That is when you really fall in love with diesel engines. You have to experience it to understand.
 
You should test drive one sometime and you will be a believer. The Rabbit gasser is no match for the TDI out on the road.

You really owe it to yourself to test drive the 2009/2010 TDI. I think you may just have much different perspective.
 
"TCH Hybrid System Net Torque: 138 lb-ft + 199 lb-ft from 0-1500 RPM"
 
So if you are saying the electric motors torque functions past 1500 RPMS AND delivers 199# ft of torque past 1500 rpms and is added to the gas engine torque past 1500 rpms then yes 337 # ft of torque is greater than 236# ft of torque.
 
Is that what you are saying?
 
Keep in mind the Camry Hybrid does the 0-60 in 8.4 seconds
and the
 
TDI does it in 8.9 seconds.
