My .02 on the Battle Royale between the S4 and M3. I don't really care about 0-60 times because I never sit at a red light, red line the engine, and pop the clutch. I am much more interested in real world action represented by 30-70mph times. I would think that the torque in the S4 would make it world class in that category.

Has anyone seen the 30-70 times for the S4 and M3?

In gears 4/5/6, the S4 works the M3. 80 kmh is roughly 50 mph. See link.<ul><li><a href="http://forums.roadfly.org/bmw/forums/e46m3/forum.php?postid=954698&amp;page=1">Auto Motor und Sport S4 vs. M3</a></li></ul>

from 60-125 mph. M3 does it in 12.9 seconds while the S4 does it in 14.5. M3 laps the Hockemhein F1 circuit 1.8 seconds quicker on a lap that's only 1:16.3 seconds long. That's a beating. The S4 is quicker on the rolling tests because of the extra torque of the V8. On the road, a good M3 driver won't be caught "off-boost".

"a good M3 driver won't be caught "off-boost"."

I don't understand that statement. The M3 is neither supercharged nor turocharged.

There is a LOT more potential left in the 4.2 than the BMW motor

I've driven the M3 convertible and wasn't particularly impressed for the astronomical price. I'd rather have the M5. Or better yet the M3-that-wasn't-homologated-after-two-years-of-stock-racing. God help us if BMW stuffs their V8 in an M3 and sells it on the street.

He means under 4000 RPM probably.

I think BMW has fixed this issue and had the cajones to extend the warranties to 6 yr/100k IIRC.

thus S4 will be a better option IMHO.
