thoughts ?

also has any one got advice about the 3.0 L tdi as i have hear its under powered for a large car and also hear that they are good with 45+ mpg will i get the same return with a 4.2 on LPG ?

thanks

Guy, it depends on your mileage, but I'd have thought for taxi/chauffeur work, the TDI would be the only option, or perhaps a 3.2 FSI 2wd

I looked at that one a few days back. If it were SWB, I'd be really interested.

Massage ventiliated seats. Individual seats in the rear, Radar cruise.

No sun roof though.....

did not notice the sunroof not there, thats what air con is for, its no big problem but it is the LWB thats the only thing but it is a sport so it still has the ride i guess ?

vary hard to find anything on LPG at the moment thats the only problem

Individual rear seats are not much use for chauffeur work if you have 4 passengers

I did some fairly accurate calculations on LPG now with the price of £1.359 for petrol and £0.76 for LPG.

I'm basing my figures on the car getting 20% less MPG on LPG than Petrol and a figure of 25mpg (not that easy to get with a 4.2 Quattro V8 Petrol).

£1.359 = £6.178014 per Gallon for Petrol
£0.76 = £3.45496 per Gallon for LPG

1,000 miles on Petrol @ 25mpg will cost you £247.12056.

1,000 miles on LPG @ 20mpg (20% less than on petrol) will cost you £172.748

These figures are easy to multiply up and down so if you're doing 20,000 miles a year, just multiply by 20 etc.

Taking the figures above, on petrol you're paying 24.7p per mile. On LPG, you're paying 17.3p per mile.

For comparison purposes, 17.3p per mile is the equivalent of approx 36mpg so you're not matching the TDi figures.

Diesel does cost around 6-7p more per litre, but just for the record...

Diesel here costs £1.429, £6.496234 per Gallon.

1,000 miles on Diesel @ 45mpg will cost you £144.361, or 13.3p per mile.

The question is can you really get 45mpg from the 3.0TDi in an A8? I know about the figure of 25mpg from my own 4.2 S8. Maybe you can get a realistic 30mpg on an A8 with the higher gearing?

I hope that this helps your choice about vehicles.

The best I see on commuting and general running around is 32.2mpg in my A8L 3.0TDi.

On a run it gets up to about 38ish but then there are no motorways in Scotlandshire above Perth!

40 odd is pie in the sky :p

Really depends how fast you drive... I reckon at a constant 70, I'll get high 30's, maybe even breaking 40 on my 4.2tdi.

I love these people that think AC is somehow an alternative to a sunroof. THEY ARE FOR COMPLETELY DIFFERENT PURPOSES. ARGGHHHHH!!! :-(

I remember when Vauxhall thought it would be better to ship it's high end 90s Cavaliers with an airbag instead of a sunroof. Was most disappointed. My sun tan is far more important than my safety...:ROFL:

Rant over.

I'll get my coat.:cool:

Zip.

Nowhere near it and my track record shows I'm rather good at getting good fuel consumptions out of vehicles. Never had less than 30mpg from the 3.0TDi and never more than 38mpg. The norm for me is about 35-36mpg

I did a run from Bristol to London,upto Ambleside in the lakes,down to Stockport then back to Bristol the other weekend ,in total 700 miles from one tank,using shell v power diesel in a D3 3.0 tdi 54 plate.Not done the maths,but had to be near 40mpg,I guess +++

so reality is that the LPG is a better option then if it was based on 145 for 1000 miles at 45mpg then 20 mpg on lpg is better in my opinion and effectively its 40mpg because its half the price, because i do not like the sound of an oil burner so that will be the better choice then i think

thanks again once again the forum pays off

Guy, be wary, LPG is more than half the price and the gap will shrink, the government will make sure of that. Anyone else remember when diesel was cheaper, before it got popular?

Personally, I'd stick with diesel, especially if you factor in it's stronger residuals and easier to sell on, whereas I fear you might be sat on your W12 for some time waiting for a deep-pocketed buyer

Unless you have th Police Spec '8 then all it takes is a press of a button and the computer fairy calculates it all for you +++

The 3.0 Diesel sounds 'ok' but definitely dieselly... The 4.2 is pretty silent.. and whenyou take the engine cover off, you can get your star wars toys out and pretend it's the attack onthe death star....

The 4.2 will also be higher insurance premiums, but nowhere as bad as the W12

thats the thing the W12 is cheaper to tax and insure by 500 quid my quote on a 4.2 was 1100 quid and the W12 is 670 Quid ? how you figure that out ?

remember LPG is harder to find as well Guy

£670 for chauffeuring?
