A big and a great post

i wonder where you get your "official" times from

Anyways, what i have been stating for a long time , is that BMW is usually very cautious in their 0-100km/h times. They are normally lower than official specs.
But when it comes to the "language" they use to describe their cars, you have to be careful. I am sure you know very well that you dont have ANYWHERE near
400nm at 1500rpm, LET alone at 800rpm. This is marketing gimmicks.

As for me i have test driven both, and strangely enough, i found the 535d to be quite linear, and not push you back into your seat like the 530d (231bhp)

r.a.i.d

Yes, off course the language "500 nm almost at iddle speed" is total BS.

The official times were printed in brochure that was given to me, and are also present in web site
www.bmw.fi.

btw, dont you find it little bit odd that according to that german site 530d is only 5 series that
have the same accleration with manual and automatic ?? These web sites contains many times information
which are not accurate, same goes with brochures too..

The push in your back comes from torgue that rises up very rapidly in a short rpm scale. It gives you the feeling that we are going fast. In that sense 535d might be more linear as you said, and with 530d when that one turbo starts to spool gives you the push-effect.

same as for the 540i/550i... almost the same with manual and auto. It is quite normal for powerful engines to be able to use the auto better than a 523i for example. Anyways i phoned my sales advisor (bmw.bg) and he stated that its 6.8s for 530d , and 7.1s for the old engine so your website has got things slightly wrong!

r.a.i.d

Well, the web site might be wrong - and from old model.
It is very common that somebody editing these sites pick up the wrong figures (btw bmw.fi gives 530xd 6.6 seconds). My sales agent apparantly cheated me to by a slower model with a huge pile of euros more

But i dont exactly believe that those figures in the german site are right either. Off course we would need to know the test conditions etc...

But magazine tests, and those wich have been conducted by the forum members, show us that BMW figures are not exactly right. So basically we are with our feelings if we dont get any data from elswhere. But to claim that a car with 41bhp and 60nm less is quicker?? - okay we all can express our opinions, thats what forums are for.

Ok after reading all the post i've come to some conclusions:
1. IMO it's best for us is to compare only bmw official data, and bmw official power charts since if we look and search we can find many tuners with different dyno runs with different results. So why not take bmw's original dyno charts into consideration? Just because it might be too optimistic? Where is the proof for that? Too optimistic for what only the 535d and not for 530d? Again where is the proof for that? IMO bmw.com it's the most credible source.

2.I'm 100% positive as logic dictates me and as bmw's official data tells me that the 535d will be faster to 100km/h than a 530d.

3.535d indeed feels more linear to a 530d because of the set-up of the tt. The push in the back from a single turbo diesel is always a slight feeling that you are somehow going faster but it might be just a feeling not a reality, because the power/torque comes in a big lump and in a more narrow rev band.

4. We should take into consideration the bmw figures from the INTERNATIONAL webpage. Why should we compare figures from local sites? Can i bring the romanian page into discussion?! It's a mess anyhow and gets updated only for Christmas :thumbsdown:...So i hope i made my point clear about the sources.

But 70kg more!

Although, it is true that the 535d is slightly quicker to 100km/h, from a standing start they're not that far apart! However, once the 2nd turbo really kicks in (i.e. in real day-to-day giving it some stick driving) then the 535d's worth shines through! The updated 286hp 535d will have the best of both worlds

r.a.i.d

Actually when you look at the 530d specs you can see that although 530xda weights 85 kg more than
530d it accelerates 0-100 with same 6.8s? (With petrol models the xi:s are considerably slower) So "small" weight difference seems not to be very much factor with engines which have that much torgue.

And most of the people tend to take their cars fully loaded wich means those official weight figures dont mean a thing any more.. comfort seats, class roof, logic7, 20 inch wheels etc..

Off course the new 286bhp will be a tad faster - as always. (335d touring 210kw weights 1720kg, and 0-100 is 6.3s. Must be pretty close to what sedan 535d would be) So the marketing people can again force us to do
another important upgrade

Weight is weight, torque or no torque... The official figures should be taken with a grain of salt. I believe the '4 wheel drive' version benefits from additional traction from rest offsetting the weight. However, increments will be affected...

yes, since you have no wheelspin when you launch
