Who needs a VR6 when youve got a TDI....

Returning to this exciting topic... , what kind of fuel consumption do
people get out of their 1.9 tdi motors when driven hard? As mentioned in
my last post, the Bora 110 tdi I hired last week only returned 35mpg over
600+ miles of varied roads. Anyone? (real distance/fuel bill figures, not
MFA type numbers pls.)

 

My friend and I drove to Donington, 200 miles at 90mph. Mk3 16v did 30mpg, TDI 150 did 45mpg.

 

Well, I was surprised by your post I have to admit.

Over 18,000 miles my Audi A4 TDI PD 115 has averaged 49.3 mpg. (This is not computer figures, but tank to tank comparisions. Out of interest the computer in the Audi is pretty good, about 1-3% optimistic, depending on where I get my fuel oddly enough)

On a long motorway cruise at 70mph I get 62 mpg
Round town I get about 47mpg.

Hoofing it about I struggle to get it into the 30s, usually around 42mpg. And this is driving quick enough to keep pace with mk2/mk3 8v GTIs on full bore.

I did one track day with it (SE suspension, not good!) and got 28mpg. My Mk1 GTI average 9mpg!

The PD engines with 115/130 seem to be the best in terms of compromise between economy and performance. The 150 is noticeably less economical. The pre PD engines are not as efficient either (eg. Your 110)

Cheers,

Drew.

we were hoofing it Drew (for 90, read 90+), he normally gets around 50ish, I used that exanmple as it gave an interesting direct comparison over exactly same roads at exactly the same speeds.

I must be a proper leadfoot then , diesel efficiency obviously can't
mask that completely. I think it would be fair to say that a relaxed driver
reaps the benefits of diesel characteristics far more, both in delivery of
performance and MPG. Loonies like me (get in, place housebrick on right
hand pedal) close the gap a bit I suppose.

 

I'm only assuming this was a 110 as it was a base model Bora diesel, - it
was a 2004 model, so is this a correct assumption, or am I mistaken??

edit- did the obvious and checked the vw site- OMG it must have been a
100. no wonder I'm still waiting for it to hit 130km/h on the autoroute,
two days after handing back the keys

obviously the vr6 driver isn't bothering to drop a couple of cogs - let me race him

 

Maybe you would beat him, maybe you wouldn't, whichever way it would be closer than most VR6 drivers care to contemplate. TDI 150 pulls like the proverbial train, once you're ahead the smokescreen seriously slows the opposition down.....

 

I always know I've successfully made my point when the abuse starts!

sorry but it's monday morning so that's about as intelligent a comment as i can come up with atm

 

Yes, it would have been a 100. A bit underpowered for that kind of thing, hence the economy would suffer! The 130 would have been a lot better!

It does surprise me that they bother making the 100ps version, the worst
problem I had with it was that you really had to blip the throttle a bit to
get on boost in order to pull away uphill etc, which, if you got it anything
other than spot on, meant either spinning and squealing embarrasingly,
or bogging down equally embarrasingly

 

This is a bit of an achilles heel with the TDIs, start technique can be tricky. I tend to do more clutching slipping than with a petrol.

Cheers,

Drew.
