However 2005.5 the got facelifted with B7 S4 (current model)... the one with big center front grill..
I know quite a bit about S4 as I was considering it a while back. And I test drove brand new 2004 and 2005.5 model as well.
Regardz,
The Torque Convertor is basically like the clutch of the autos.....it locks up once a desired speed is reached. When you brake boost a car it starts to heat up, that is why if you lay on it for more then 5 seconds you could possible damage the drum and bend the fins inside the TC.
Now does anyone offer a Aftermarket/Higher Stall for the c32?
The stock 2.7 liter twin turbo motor on the older S4 was only 250HP stock, but easiliy modified to 350+HP. They're also lighter than the V8 model.
So, the only S4 to fear is a modified, B4 S4.

The Best of Mercedes & AMG
The manual revs to 7200 rpm redline, the auto cuts off at 6800, and being an auto with torque converter and not the sportiest transmissions out there (tiptronic) they are about 0.6 or 0.8 seconds slower to 60 mph compared to the manual s4. I think they tested the s4 at like 5 seconds with manual tranny, and 5.6 or 5.8 with tiptronic. So AMG must always take the tiptronic. Manual depends on the driver, but still with equal drivers c32 or c55 should edge out the s4 after 60 mph.
It's slower to 60mph and slower to the quarter mile. The S4 is simply heavier and underpowered relative to the C32/C55. The only scenario where the S4 will have an advantage is in the wet.

and does Benzo post here anymore??
I just test drove an '06 S4 today (with a 6 speed auto)
... I was dissapointed with the transmission as it did not shift at the 7000RPM redline, but overall good smooth shifts. Pulling power was not to bad but not too exciting.

I wouldn't take on a C32 or C55 in the dry in a straightline and expect to win. They're quicker than even their impressive on-paper stats suggest.
Someone made a good point about the S4 being slightly peaky at low revs for a V8. It's cos it's fairly high output for a NA V8, which is why torque is 302lb rather than c.330. Same story with the RS4 which is 317lb despite its 414brake, but I wouldn't recommend racing that off the lights. Of course, it's costs a fair bit more too.
any high revving engine will produce more HP than torque. their torque curve is pretty consistant with their hp curve. low revving V8 like the now old 5.4 liter AMG unit that's used in the C55/SLK55/CLK55 produces more torque than HP. I think this is pretty much true for all engines.
the only thing S4 loses on is the weight.
for Auto S4 you'll need to put the gear in the manual mode for it to shift into the redline.

From the first light we lined up and he looked over and asked me "are you ready?"... i reply "anytime when you are, hey wait is that thing AWD"... he smiles and grins!!! Light turns green and low and behold, my RWD C32 holeshot the AWD S4 by 1/2 a car and I kept on pullin and pullin.
At the next light, he tells me "dammmnnn that thing moves". We line up again and he tells me lets go again. This time i hear him powerbraking nasty (holding both the brake and gas at the same time to load the launch, very affective on AWD automatic cars with lots of low end torque, say from a V8). So I brake boost and load up the torque converter a bit. Light turns green and low and behold I get an even better launch and holeshot him by 1 car this time and kept on pulling.
Great way to end the night!! It goes to show how somebody whos learned their car in and out can make a difference. I cant wait for winter cool weather to roll around.
good kill man
I had a 2000 A6 2.7T which has the S4 drivetrain. I sold it in 2005 after losing all confidence in it's ability to stay in one piece. Turbo plumbing, coolant plumbing, transmission, control arms... Keeping in rolling was a $500/month habit! Once you roll up your sleeves and see how it all gets put together, it become pretty clear why it keeps breaking! Rube Goldberg engineering.
Maybe it's just a matter of time, but the C32 seems like a tank in comparison.
I currently have MTM chip and neuspeed exhaust (stage II) I'm putting in an RS4 clutch and AWE aluminum flywheel and down-pipes in a week or so. K04s this spring - I'm thinking it will be my track car after getting a taste of what driving a performance-stick is like. Seriously, it costs like nothing to mod this car. It's not even close to the same level of car as my C32 - interior is not as nice, uncomfortable driver's footwell, no head-room, not as fast, not even in the same category as far as seats, etc...it's going to smash the C32 in a line when I go stage III.
Moderate thread-jack there, sorry.
