I am going to order a second Audi, an Allroad 2005 in mid july/August. I am still debating whether to get the 2.7T or the 4.2. I am planning to take a fully loaded model except for GPS. The diference in price is not an issue (about $2500, some of the paying options with the 2.7T come included with the 4.2). I am planning to keep the car between 5 to 10 years....

If its a TIP then with the 4.2 if its a 6 speed then get the 2.7T.

... and you can put 87 octane into the 4.2. Though I'm sure most would frown upon doing it.

unless you want a stick, live at altitude or want to mod......go with the 4.2........imo of course..

. . .with your qualifications as stated, that is.

If you want a stick, go with your only choice, the 2.7T. If you only want an auto, go with the V8.

Perhaps if you really plan to keep the car as long as you say, I would urge the V8 since I am less confident in the life span of the turbo. In any case, I would, near 50K miles, consider purchasing the then available Audi-factory-service plan du jour.

My experience with the V8, too, is that the milage for the performance makes this a pretty easy decision.

I must tell you, however, that my wife and I, with four Audis with navigation under our belts and with the dropping of On*star as an option, would encourage you to consider the Navi system as a safety, convenience and NOW security option.

The system, often derided as "navi-lite" works well and once you use it, it really does become one of those "don't leave home without it" features.

Now, having said that, if you live in a relatively rural area or rarely go outside of your comfort zone, well, maybe its value is diminished.

There are dozens of times that the navi kept me from a stupid attack, got me out of a "bad part of town" or saved time. Whenever we travel to unfamiliar places, the navi allows me to concentrate on driving rather than "hunting."

Navi systems, are expensive (relatively) considering the true cost of the electronics that comprise them -- but, IMHO, they are worth every penny.

Just a thought or three. . .

. . .every one of the managers and technicians go to great lengths to tell me about the "false economy" of putting regular in the V8. They claim the engine management system does retard the spark (effectively) to prevent pre-ignition (ping). But that the cost of this is extra fuel is used and the power is diminished.

I have read the postings here and elsewhere from people who put regular in their 4.2 equipped Audis and even claim "no perceived" difference.

Beats me. . .I currently don't have the 4.2 anymore and of the three I had, I never used anything other than the highest super gas I could find at the moment (usually 93 octane).

I would seek professional advice on this matter -- for I certainly see no value in buying more octane than is required, but if the truth is that the 4.2 uses more gas and produces less power with regular, I would agree, 'tis a false economy, indeed.

Drive both and decide which feels better to you.

Regular @ 2.00 per gallon (NJ) = 20 MPG
cost=.10 per Mile

Premium @ 2.19 per gallon (NJ) = 22 mpg
cost is .099545

Its a wash... I go premium because the fun factor does increase.. and it keeps the engine in its proper tune.

Most of the feedbacks confirm my first choice of going with the v8. I wish I could take a manual trans. but my wife might be driving this car as well so it is going to be automatic, plus I plan to keep it....turbos will have to be replaced at some point and my experience is they do put more strain on the engine. Car manufacturers used turbos to get more power out of an engine without spending a lot of money on extra design/engineering....

Thanks for the feedback.
