I find my 150hp '00 peppier than my '02 170hp.
The clutch seems different though and the car seems a whole lot lighter (and smaller). The '00 is not quattro, but I doubt that the 300lbs accounts for all the difference.

also heard people say cvt has pause.. ive not noticed at all in our 2.0.. must be a 1.8T thing...in
hot weather only? how many people here have experienced lag on 1.8T cvts in heat?... or anytime else... or with any other engine?
I havent from a standing stop in a 2.0.

FWD does make a big difference - Quattro has more drivetrain power losses, (more)
more rotational mass to get going from a stop, etc. I'm positive that's part of why your FWD '00 feels peppier than the Quattro '02.
(along with the added weight on the car overall, of course.)

I would have mentioned the drivetrain losses, but the way I figure it
What the car loses in the drivetrain, it makes up for in grip for fast startoffs, leaving weight as the major factor in making the car more sluggish...
however, now that I think about it, the drivetrain losses would over power any extra grip you had on start off unless you really launched the car in a way that would make the wheels spin in a FWD car.

Getting 17" OZ Superleggera wheels makes CVT even more efficient...
Unsprung weight on the wheels definitely takes advantage of car's hp capabilities (more so than stock wheels and tires) and translates to better car handling (along with Dunlop SP5000).

True, Audi always claimed that, but it's something like 25-30% losses for quattro (m)
which I think really affects it compared to FWD (which is around 15%, if I recall).
In my view, that higher loss completely negates the extra 20hp. Though that didn't stop me from getting quattro on my 3.0.
I'm willing to bet that Audi is trying to work on that by improving upon the Torsen differential design. I remember reading a few years ago that Audi was working on it for the next generation A4 (i.e. our cars), but it didn't happen.

Same here. Both are A4 1.8TQMs. I think CPU ULEV changes have hurt effective torque ...
It's now an ultra-low emmissions drive-by wire car (now, both the driver and the electronics share control of the throttle). It's my belief that we've lost torque in certain driving conditions (hot-rodding and squirreling around) as a result of these changes.
I'd love to hear the results of a drag race between on '02 and an '00 similarly equipped.
Note: The A4 is heavier now but I calculated the power to weight ratios for both and the '02 (on paper) still comes out on top.
Oh, one other point, it seems to me that the new '02 is more sensitive, power wise, to temperature and humidity changes than was the '00.
