In Sports mode, when using the paddles, it only shifts when you tap the paddles...I think it only activates first gear when it sense a certain speed before the engine stalls (it IS an automatic gearbox after all).

Interesting... I must have misunderstood all the DSG info I have read then, as they all seem to imply a pre-loading/selection process:

From http://www.autozine.org/technical_sc...ear_manual.htm

"Take this example: assuming the car is accelerating at 2nd. The clutch controlling the even gears is now engaged while another clutch is disengaged. From the data taken at throttle position and rev counter, the computer knows that the driver will select 3rd soon, thus it will connect the 3rd gear. Because at this moment the clutch for odd gears is disengaged, the pre-selection of 3rd will not affect the 2nd gear currently running. When the driver touches the gear-shift paddle, computer signals the even-gear clutch to disengage and simultaneously the odd-gear clutch to engage. In this way, gear is changed from 2nd to 3rd instantaneously, without any OFF period, without any delay - the only delay is caused by the smooth disengagement and engagement of the two clutches. Therefore power delivery is smooth and uninterrupted.

Pre-selection of gears quicken the shift a lot."

Yep, that's why I believed SMG/F1's single clutch system was better at the track, as it shifts up or down exactly when you tell the car to do so... you can bounce off the rev limiter all day if you wanted. However, if it's true that I have misunderstood the DSG info I've read, then DSG shouldn't predict what gear you want next and behave like a faster SMG/F1 transmission. However, if it does predict and preselect, that's the problem. Like I said, when I tested the A3 with DSG, this seemed to be the problem, but who knows if that's been addressed already.

Here're two sound clips from the new V8 on a dyno simulating a lap at the Nurburgring, and 0-200 kmh acceleration:

The first details and pictures of the production E92 M3:

It looks like the CF roof is a standard feature. It also looks like it will have adaptive dampers, like the new Bilsteins or Porsche's PASM (which are Bilsteins).

I'm not sure the car does anything for me, but I want to see it in real life before deciding.

Due to low expectations, I like just about everything I hear about this car, but the more the car becomes reality, the more I realize this is not a true M3. This is more a tribute to the original M3's (E30 and E36) and a technology test bed for BMW. It still may be the car for me when it becomes available in the next year or two, but I think the heritage and history behind the car is muddied in this iteration.

When the E46 M3 came out, it was a monster that could not be tamed, but it already showed signs of a less competent M3. Then the market was flooded with sporty coupes and sedans in the years since, and now BMW has compromised the car even more in order to beat their competition. I understand the decision, but the badge on the rear is less an indication of the exceptional car that wears it, and more a designation that this is simply BMW's premier luxo-sport coupe.

That said, I challenge BMW to prove me wrong.

How was it less competent? By any measure it was way faster than previous M3s (track and straightline).

I said it showed signs of being less competent. It was a clearly larger, heavier, more luxury oriented car than the previous versions. Also, the direct racing ties were gone due to homologation rule changes, changes to BMW's racing programs, and changes to the market of the production vehicle. The E46 really became the first M3 that was a standalone luxo-sport car from BMW that happened to have the same badge as racetrack-bred sports cars. The same arguments can be said, although less so, for the E36 version, but in my opinion the major divergence occurred with the E46.

I'm not bashing the car, I'm just stating my feelings on the history of the badge and where BMW seems to be taking it. The E46 M3 is a fantastic car, and I think the E90 will be a blast to drive, but I don't think BMW used the same philosophy to build the E30 and the E90 M's.

Floor pictures from the Geneva auto show look much better:



I'm almost afraid to find out how heavy it is since the 335i coupe is over 3600 pounds.

That would look wicked pissah if it had the Camaro "Screaming Chicken" on the hood.
