Gotta love Tdi economy

[benno]

0-100km/h in 3.5s

I find that hard to believe.

[Greg Roles]

in a way... but i can carry 4 people an luggage.. therefore being more efficient.

...with no drop in performance.........

still great figures for a hot car, even if your watch is a few seconds fast...

Who said my daily drive was a VW ????? .... I did say ride .... Suzuki GSR600 uses 4l/100km IN THE CITY, and probably does LESS than 3.5s 0-100km/h even though I'm a bit wary to push it that hard ....

Yeah, and only 1 passenger and a very little bit of luggage .....

BUT ..... its quick for commuting, quick anywhere else , cheap to run AND better for the environment than any of the cars on this forum ...

Also ..... my Polo makes in excess of 360NM so loading it up delivers very little drop in performance either ....... loading it up and fanging it does drive the consumption up, but that is what sports hatches are there for ..... not for silly fuel economy runs .... .... even though it seems it can do that as well. I admit though that that is not its main purpose in life.

Very clever mister....you win this round....

Regardless of your economy figures this thread is meant to be about TDI economy anyway so why drag a petrol car and motorcycle into it Back on topic anyways, I only have 7,500 k's up on the GT so far and the figures have never exceeded about 7.0 L / 100 kms (properly calculated not onboard figures) and that has been in stop start traffic, having a fang on occasions (very occasionally ) and a bit of highway cruising as well. I personally won't be going back to a petrol car again, my little Putt Putt diesel will do me fine and with the prospect of the economy only improving as the km's on the clock get up a bit further, I'll be even more satisfied

I also used a calculator, not the MFD to state my figures, but the MFD is not that far off, but I agree, it can be a little optimistic.

And given I've only had the car for less than two months, I doubt I'd go back to petrol also. I suspect that the diesel cycle engine will be the way of the future. Even now, they are finding their way onto light aircraft, most notably the Cirrus and Cessna are considering it also.

How expensive are other running cost? .......tyres? and how long they last.
How many airbags do you have on two wheeler?

And how long does it take to don your wet weather gear and take it off (or to change into dry clothes) ? When I used to regularly commute in Melbourne on a bike I used to (sometimes longingly) refer to cars as "the ultimate wet weather gear".

If they are considering running diesel in planes, I wonder how long it will be before we see a TDI motorbike ? Imagine the fuel consumption you could get out of an appropriately designed diesel bike !

Diesels for light aircraft will become more common because AVGAS isn't plentiful, cheap or good for the environment - it contains lead. Some existing aircraft (Cessna 172s etc) can be retrofitted.

Aircraft diesel engines run on Jet A1 fuel. Hmmm . . . wonder how my TDI would run on that stuff!

Do not even think about it as the fuel is too dry (no Sulfur or any lubricating properties). I must admit though when we have had to drain a tank to work on it I will use it in an old tech diesel by mixing in 2 stroke oil until there is an oily feel when rubbed between your fingers. I have used it in the Nissan Grenade as a get out of jail.
Also remember the pressures in the PD injectors is much more than in a turbine engine. The pump output is only 900psi approx and the nozzle working pressures are between 60-150psi on turbines.
Many years ago we had a batch of new sulfur free fuel and we had many pumps shear due poor lubrication and we had to add a teflon liquid, about a cap full to each wing in a Metro (Flying Tampon) until the refinery fixed the problem.

Now that our Eos has reached 10,000Km, I have run my first definitive fuel consumption test for the MY09 TDI & DSG combination. The test was done in a mix of 80% country and 20% town driving with the climate control permanently on.

Distance covered: 842Km

Fuel used: 42.65 litres [Shell diesel]

Fuel Consumption: 17.67 Km/litre, 49.92mpg [Imperial], 41.56mpg [USA]

Who needs a hybrid with their inherent compromises when you can get this economy and performance as well .

we just did a trip to Wagga Wagga and back via Sydney from Gosford in my mk3 TD. Achieved 5.14l/100km! 2 up with luggage and sound gear for my sisters 21st party. oh yeah, used the air conditioning for 90% of the trip (darned black car)
woot!

gldgti,

Not bad!
I just did a round trip Melb Syd Melb on Sat Sun for niece's 21st.
5 adults and boot full of airbeds, sheets, towels and clothing and averaged over the 1,832km 5.19l/100km using aircon all the way and mostly against a horrible headwind on both directions!
Oh and sitting on 2,100rpm for most of the trip on the Hume.
That's about 111km if the gearing suggested in Wheels a couple years ago is correct (53.1 km per 1,000km)

Cheers,

Neil.

Kero works great

I love weight and balance time, 5% ee100 ashless dispersant at 5% and bob's your uncle. I used to cart the 44 away with the siphon hose running from the back tray into the fuel tank from str8 under the metro wing

oooh i wish.

with the old dubs the longest 'box you get is mine (CHD code) and its 2800rpm at 110km/h..... no shame in flying the old TD flag when you consider that little factor i reckon

any TDI owners willing to try an economy run without using top gear???
