My Ride: On Order, due in May - 2007MY 530D SE, Silver Grey, Black Dakota, Auto, Brushed aluminium shadowline,sports seats / wheel, hi fi speakers, mats, space saver wheel and a few more bits
I notice when flooring my new 530D that the DS mode keeps on the revvs longer. Just curious, as diesel are more tourqey in the lower revs, is DS mode actually quicker then D? Or is it quicker to manually change in DS mode to get the fastest acceleration

Would be nice to actually time the 0-60 of D and DS... I'd say the petrol models definitely benefit from holding the revs...

DS is good for starting in as it changes faster while as in M, even you are fast you are not that fast as the Stept. It is true however that in M mode you can also change before the tranny would

Note also that the petrol cars have four fuel maps--2 for D and 2 for DS. So, for example, if in DS, then one map (call is NDS) is for normal starts and the second (call is RDS) is for very rapid starts. And, let the corresponding modes in D be called ND and RD. OK, well, NDS is more aggressive than ND, and RDS is more aggressive than RD in the Step petrol cars. So, at least with the petrol Steps, DS again is for optimizing performance/acceleration. I am not sure if this is the way things work on the diesels.
Finally, in the pertrol Step cars, automatic shifting occurs at redline when under full acceleration. In this regard, one cannot out perform the Step through manual shifting--because if one delays trying a manual shift too long, say until 6,100 RMP, then the Step will not allow the manual shift to occur. In other words, one can shift manually with the step under full throttle, but the shift will have to occur so early that it could not conceivably be optimal. Go figure???--manual shifting with no opportunity to beat what automatic shifting can do on its own. I am not sure how any of these observations apply to the diesels.
I'd be interested in hearing whether, and to what extent, you guys think that the things that I mentioned in relation to the Step petrolers hold in the context of the Step dieselers.

IMO, BMW sets its Step cars up to maximize performance/acceleration in DS--including the automatic shift points. If not, then why have a DS mode at all? So, if the gears are held longer in DS, then, IMO, it is because BMW thinks that the DS hold lengths are optimal for performance/acceleration.

I am sure you have explained the correct scenario's for petrol - love the free revving stuff, but I don't get near 6,000 rpm. I think I need further advice from one of our diesel brothers. Unfortunately I aint got steptronic either

As I understand the optimal shift point should be where the HP (measured at the wheels) in the gear you are in would be less than that available in the next gear up OR where you would otherwise run out of rpm.
In most cars the effect of gearing is such that the HP in the next gear up is less anyway - so in most cars the optimal shift point is the redline.
In the 550 peak HP is at 6300rpm - close to the redline - so the DS pattern - which shifts close to (or at) the redline would seem optimal.
In the 530d peak torque is delivered at 2000rpm (or 1750 in the new one) and is flat until around 4500rpm when it dives off quickly well before the redline of 5500rpm.
Peak horsepower is generated at 4000rpm. Since HP always = torque at 5250rpm - I THINK that this explains why the peak HP of the diesel is comparatively low given the level of torque - because it is generated lower in the rev range.
So on engine HP alone - a redline shift in a 530d should be suboptimal - and an optimal shift would be at 4000rpm.
I have found some shift point calculators on the internet - but these require that you understand you gear ratios - and I have no idea what these are for my car. Without this - I cannot work out if the gearing is such that the HP at the wheels is always going to be lower in the next gear up anyway - or if the the optimal shift point is REALLY lower than the redline.
My gut feeling is that it IS lower than the redline and hence that the kickdown and DS modes of the step are not ideally set-up for the diesel cars - but I would really like to be able to know this for a fact.
In a petrol car with step (say the 550i) peak HP is very close to the redline

The above is for the original 530d. The 535d obviously has a far better spread - peak torque arrives a little earlier at about 2200rpm and keeps going strong to about 4000rpm - almost 500Nm. Peak power is at 4000rpm.
Therefore, I don't see the point of super-revving the 530d?
