Gents,

I'm cautious with this one and without trying to start a war just wondered how much different a 335d feels when you boot it from a start compared with 330d?

I know specs are similar low down and I assume the 335d will pull more at higher speeds but wondered how much different they actually feel 0-60? Or 0-100.

Also do they both have two turbos? What's the difference with the engines?

A thousand thanks

No 330D is single turbo.
I had a 330 before , 335 now, both cars were generally quicker than I'm prepared to go on a public road most of the time.

330 was S drive, handled much better out of the box than my x drive, ACS springs have narrowed gap though.

Used to see the traction light on the 330 a bit, never seen it yet on the x drive.

Test drove a 335d before eventually buying a 330d. Both xDrive so no traction issues for either. From 0-30 I'd say there's not a lot in it off the line, from there onwards the 335d is noticeably a quicker car.

Neither had the top end I was used to coming from an M135i and in the end it came down to a good deal on a fully loaded ex-demo that saw me into a 30d. If I could've, I'd have bought a 35d but I'm happy with my lot. Both great Diesel engines.

[jamiem1987]

as above very little between them in actual fast "feel" - i had a 330d and upgraded to a 335d last year and to be honest the 330d was a much better drivers car but im sure this will but to due to the springs which will be sorted soon.

You'll only feel the difference above legal speeds in my opinion.

As far as the E9x is concerned, the 335d is reasonably quick up to 100.

Over 100, it's awesome.

I seem to find it "wanting" more low down grunt at sensible overtaking speeds, i.e. 45 to 70

Not driven the 330d, but its my understanding that the two turbos on the 335d are fixed vane and therefore are better for power delivery across the narrower rev range that they operate. The variable vane single turbo of the 330d must operate across the entire range od revs and this reduces its ability to deliver the same amount of airflow. Therefore from start off the 335d smaller turbo will be better at delivering power than the single turbo of the 330d, so the 335d will pick up better with less lag. I thought this was the whole point of the bi-turbo system.

Maybe its not that noticeable when driving them separately as they are both quick, but the two alongside each other then the 335d will pull ahead from the outset, otherwise what's the point?

I think your right. I have been reading up and apparently the 330d has a twin scroll, single turbo whereas the 335d has two separate turbos and therefore reducing turbo lag. The twin scroll has two separate chambers but only one turbo...I think.

I ll second that about the 335d. Up to 100 it's quick. After 100 it's manic. Up to about 135ish there's no let up. I'm too chicken after that.

Keep going, you'll love it :-)

Visiting Germany in June so will test and feedback :-)

330d N57N engine has a single VGT/VNT (variable geometry/nozzle turbo).

335d N57Z engine has the bi-turbo setup. Smaller turbo is similar to the 330d with a VGT/VNT. Larger 'second' turbo is a fixed vane design.

The bi-turbo setup allows for more instant pick up and boost at low rpm, from the smaller turbo, plus a wider boost range at higher rpm and loadings from the large turbo. Result, best of both worlds!

I recall the engine debates when the first 35d engines were introduced. The high end urge was where users found the real difference, even with the low end being slightly improved. I remember one user who had driven both engines in Germany, commenting it was 120+mph, where the 535d (in his case) showed how much better the 35d engine was in real world driving performance.

Exactly this - honestly i'm missing my 330d as i mentioned above it was a much better drivers car, regretting the change to x drive its killed the drive (for me) but i can see how people like the stability and traction.

Maybe i havent noticed much difference between the 30d and 35d because my 30d was s drive hence less weight?

Hoping it may free up a bit over time.

[teaston]

I found my 330d "felt" as quick as my 335d low down, probably because of the shove when the single big turbo kicked in.

The figures on the speedo disagree though obviously.

There is strong opinion that the 30d is the 'sweet spot' in the diesels. Certainly shows in the 5-series where both are RWD. For UK driving the 30d suits many drivers, sweeter engine and more frugal, lower overall costs, little difference in day to day driving.

I've driven the 535d and 530d, the 535d has the edge IMO, but is it necessary? Perhaps more a 'nice to have' model. Of course there are those who must have the most powerful model and even then (for some) it needs tuning. For many users a 30d does the job required, without any real compromise.

couldn't have put it better myself, if i could reorder this car it would be with the 30d engine and s drive... x drive really is completely un neccesary for me, maybe for a real upgrade in performance i should go M140 or 340i?

[Ajs_435d]

I've always said I didn't really need a 435d and a 430d would have been fine. A 6 pot diesel is great and very smooth. A remapped 435d is hot hatch beating performance but with much better Mpg and less excitement.

[dopper99]

Those that prefer sdrive can go for a 330d and put the MPPK on it then it's near 335d performance as power to weight is similar.

It's what I did with the F10 30D with a tuning box, quick enough if that's possible and refined

[evdok]

I have the 30D & brother has the 35D, both xDrive. The 35 is much faster after a ton, 40-80 also gets the edge, as for driveability the 30 feels more nippy but compared to the 35 it feels a tad weaker...unless you do long/motorway trips the 30 will be more than enough.

Both great driving machines.

thats why i dont think i'm noticing much power difference with my new 335d, the x drive must add a load of weight as its no where near as nimble as the s drive 30d

How many miles on the 335?
