Default POLL: What is the best c5 a6 engine

What do you guys think is the best one audi put in the c5 a6.

There are four engines (2.8, 3.0, 2.7t, 4.2), but really only two (2.7T and 4.8) make sense to choose for the better one.

Personally i say the 4.2 is the better engine, in the long run there is no real replacement for displacement. Nonetheless I love my turbo. Love em.

4.2 is the more reliable one.. 2.7T is the best for power/modability

I'm partial to turbos for the reasons stated by NO.KIMCHEE.

There is no "best" engine IMHO. Depends on your priorities.

Default For reliability

The 4.2 seems to be the best of the lot. It has a pretty long history dating back to the V8 model. Plus you can get it with turbos too!

Best of both worlds! ;-)

Default As April said, depends on your priorities. For example, I spent plenty of time behind the

wheel of BD's new 4.2 - all highway miles - on the drive back from Chicago. I must say that the 4.2 on the highway is a better engine than my 2.7T... lower RPMs at a given speed, tons of power on demand, decent fuel economy (comparable to the 2.7T), less noise, etc. etc.. It was a noticeable difference. The car begged to run all day at 80-85 mph-that seemed to be its "natural speed".

Conversely, for most of my driving (back roads, stop and go, etc.) I'd take the 2.7T: more low end grunt, better fuel economy under those conditions, plenty of power, etc.

So it really depends on the situation and your priorities. I'm still very happy with the 2.7T but if I were going on a cross country trip I'd be happier with a 4.2 (for that trip).

Maybe the best solution is the 4.2T as Dave Lee pointed out! ;-)

Default Do you want fast w/ little upgrading (4.2), or faster w/ some upgrades but less reliability (2.7T)?

Also, the V8 only comes in Tiptronic...but the 2.7 can be found in 6-speed (the selling point for me). My next C5 will likely be a V8.
