I had a 2011 3.0 TDI Execuline that met and unfortunate end a month back.

I picked up the replacement yesterday and drove home 1400 km. 2014 3.0 TDI Execuline.

Both on stock OEM rims and tire sizes.

Two things I noted:

  1. The fuel economy seems noticeably better: 8.2L/100 km (28.7 US mpg) on the 2014 drive home compared to best ever 9.5L/100 km (24.8 US mpg) on the 2011. Both hand calculated
  2. Range per tank: the range on the 2014 is 33% greater than the 2011, which the fuel economy doesnt completely account for. (1200 km vs 900km) I checked back on my Fuelly records and the most fuel my 2011 ever took was 76 litres. That would be from virtually empty. This morning I filled the 2014 and it took 80 litres, but the fill was not from empty. I still had 220 km range.
The range per tank diffrence, backed by my fuel records lead me to believe that the 2011 had a smaller fuel tank. The specs for both units state 99 litre capacity, but given the most the 2011 ever took was 76 litres from what appeared to be empty suggests a smaller tank.

What does the Treg-averse say?

Both my vehicles are Canadian market. The two particular sizes you note, in conjunction with the noted fuel economy differential, seems to align with the range differences.
My 2011 had a 85 litre tank.
My 2014 has a 99 litre tank.

Yeah besides the tank differences your 2011 had the CATA engine and your 2014 has the CNRB engine
I anticipate that is the source of the difference in fuel economy. It feels more powerful and has better fuel economy, which is a rare combination.

North America should all be 100L. My 2004 V10, 2006 V8, and 2015 TDI have all had 100L tanks.

There is no way my 2011 had a 100 litre tank. I usyally fill before empty, but I have run it down one or twice on the highway to 0 KM range. The most fuel I have ever put in the tank was 76 litres.

no 11s and 12s had 85l tanks
I have covered ~350k kms between both 2L & 3L CRs and have ran EVERY SINGLE tank to near zero.....
Both CP4.1 & CP4.2 have never complained.
same ive had 3 cr 2.0 tdis and 2 3.0 tdis and go below 1/4 tank every time

Do you have some sort of proof? ETKA lists 100L tanks for 11-12.
lol only the fact that i own both and have filled both...it has a 85 liter tank your hard pressed to put 80 in it....ive owned my 12 for over 6 years and put 180k on it and ran it below empty nearly dry all the time it does not have a 100 liter tank.

Which 100% aligns with my experience on my 2011

If you run one of these to empty prepare for a lot of expensive repairs. I guess I understand the curiosity,but is it really worth blowing up the HPFP ? You can precisely figure your mileage buy the fill up method by zeroing the mileage counter when you fill and how many liters it takes, EZZEE,peasey. My 2016 gets filled at about a quarter of a tank and takes about 20 gallions.

lol i dont subscribe to the mass paranoia...ive filled tdi for 15 years below the fuel light almost every tank, never had a single issue with the 5 or 6 ive owned...fuel quality is far more of a factor by far

To improve power AND fuel economy even more, check Malone stage 2. However, this will void the warranty.

You might not appreciate the fuel economy right away if you enjoy the extra power too much hehehe
