Who's got a new X5 coming with the 4.0d
 

Anyone the new 4.0d motors yet!

You mean the 40d. That's the official designation. Calling it a 4.0d sounds like you are talking about a 4.0-litre engine. Sorry to be so pedantic.

I know this is an old thread but I was thinking if BMW decided to stop ringing the neck of the 3.0d (40d) and made a diesel variant on the 4.4 V8 as they have with the 3.0i, based on litre per Kw it would develop around 330Kw & 880Nm you would nearly think it would be a sufficent line for the X5s 3.0d & 4.4d and possibly the 4.4M(petrol). I might bring it up at the next meeting :D

I'd be surprised if BMW would bother with a V8 turbo diesel in these times of environmental and fiscal responsibility, but I may be wrong. The 40d is as good if not better most of the V8 turbo diesels anyway. But you're right, given the same specific power/torque as the 40d, you would be looking at 330kW and 880Nm for a 4.4-litre V8 td.

I'm surprised BMW hasn't gone to a V8d by now as part of their line up when you consider that both VW 5.0d V10 toureg & AUDI Q7 6.0d V12 are out there on the market. Also the power race going on with the Euro SAVs hence the introduction of the X5M, so I think BMW sees a level of importance in the power stakes which is why they keep uping the anti in their model range. I agree that the 3.0d that BM runs is an amazing power plant I've only modified the exhaust and remaped the ECU result 203Kw & 615Nm which in a lighter E53 the vehicle is incredible to drive. On another note I went into a Mazda dealership recently to price a new 5 cylinder td one tonner due out in Dec they told me Mazda will no longer be offering a petrol version in any of their commercial range in the future, a trend that others will probably follow.

V10 td Touareg didn't last long. Old tech Unit injection engine, effectively just a pair of VW's long serving 2.5 inline fives on a common block. Audi's 6.0-litre V12 has also been a bit of a sales fizzer.
As for Mazda, even with their current range of BT-50s, it's all turbo diesel ... a 2.5-litre four in 2WD or a 3.0-litre four in 4WD. Same at Ford re the Ranger. No petrol Isuzu D-Max's either. Mitsubishi is also only diesel in the Triton 4WD range while Nissan and Toyota only offer petrol V6s in one model in their 4WD utes.

I've heard tri turbo diesel for next year, starting with x6
 

Likely good for 290kw, 650 to 700 nm

With all this amazing technology going into diesel engines and as a result increasing sales, that will give them justification to charge us even more for diesel fuel right! I wonder with eight speed autos, tri turbos and what ever else they come up with, how the threads will read on the forum in years to come.

Yep
 

Julia will tax the *hit out of diesel by simply not droping the price. Labour Sux

:iagree: thats true but if Julia is going to move the country Foooooorward she will have to, at least one of their policies has worked....thinking....no can't think of anything :D

As suspected
 

tri turbos are coming ..starting with M diesel performance range .. will be interesting to see Aus pricing on these ..I reckon $150k for the X5 50d ... which once again is a big ripoff compared to our US counterparts (even through they won't get the X50d in its current format, more likely next gen X5 will get the try turbo for US market)

It will be interesting to see what the non-M 50d does in terms of power and torque, if there is one.

$150K?? geez... if its the same as an X5M (save the power plant) I can kind of relate... but from what I've read they're quite watered down these M performance cars?

Back to the OP topic, yes I'm sitting in mine now! Black march build 40d, innov, side view, heated seats front n rear, third row, self lev, tv, pro nav, soft close, 21" 239, oyster, tinted, pro hifi. I will mod the dp filter and have it tuned......just after I test drive a 50d :)

Hi Fraser,

My M50d is in pre-delevery, had the 5mm caster bushes made got them yesterday and I am awaiting on the hand made ceramic pads. The M50d runs the brakes off the X6 V8 Hybrid that was sold in the USA, so they had to get the pad blanks to put the ceramic material on.

They said in an email today that the pads are hugh as the front rotors are 385mm in diameter.

Anyway no long now, probably another 10 days.

Why the castor bushes? My 40D with 21"s will tramline a bit on grooves on the road, but other than that I haven't experienced the "pull left".

I would say first off, you have'nt got the Adaptive Drive suspension components which causes camber drift and also the lefthand side wheel base is shorter than the righthand side by about 5-7mm on the X5.

The X5 is setup to be driven on the other side of the road (lefthand drive), so when you drive on our side (Australia) on a lefthand cambered road it drives left, its fine on a dead level road.

The X5 has no adjustment, not like the Merc's that have castor kits for Australia. If you drive your X5 on the righthand side of a normal Hwy where the camber goes to the right you will find the x5 will drive straight and not go to the right, thats the castor setup of the 5mm shorther wheelbase on the lefthand side of the X5' wheelbase.

Now when you drive on the lefthand side of the road with a lefthand camber the x5 drifts left, it should stay straight, to fix this you need to lengthen the lefthand side and shorten the righthand side wheelbase, hence a castor kit.

And I have had techs all over the X5 some 5 years ago (RACQ & Fulcrum R&D) and had several different frontend components flown out from Germany by the BMW engineers to try to fix the problem, in the end Fulcrum developed these bushes.

My old X5 (M-Sport 35d) had these castor bushes from the day I picked it up and when I sold it 2 weeks ago it had done 73,000klm, I put new set of tyres on at 69,000klm, the ceramic pads were a third worn and the rotors were still within spec.

As you can tell I am very finicky when it comes to vehicles and expect a car sold in Australia to suit Australian standards, just putting the steering wheel on the righthand side of the car means nothing, you have to take into account that our roads have heavy camber, rotation of the motor and the way the adaptive drive torques and the fact the X5 is shorter on its lefthand side and the brand of tyre.

The average city driver would probably never realise the above, even Mercedes does not advertise the camber problem, and I have owned many Merc's. You drop the Merc off, complain it's pulling left and when you pick it up they stay they fixed it ( they don't tell you they put a $79 castor kit in). They take the chance you don't pick the fault and that not all cars pull or camber left, the average housewife hits potholes and there goes the alignment anyway, there another $150 they can make out of you at the next service.

No adaptive drive for me, although my brother says its a good thing in his X6 - but insists the ride is still better in his HSV Senator. Have you gone the ceramic pads to try and get away from the brake dust?

Yes, as metioned in my previous post I did 73,000klm on the ceramic pads and they were about a third worn down, the rotors were still in spec as well, I got the BMW dealer to do the roadworthy couple weeks back when I sold it.

I have attached 2 photos, the yellow caliper was my current M-Sport 35d that I had just sold, this had ceramic pads installed.

The second photo is on the front brake on the new X5 M50d, as you can see the caliper is nearly double the size. My new M50d shows up in the next couple of days, the calipers will be removed and painted, the new ceramic pads are being hand made and should arrive by the end of the week from the US.

Any different brake performance? And dust?

Big rotors too. ;)
The rotors on M50d are 385 mm at front vs 395 mm on X5 M.

Had a look at the X5 M rotors & brakes yesterday at the local BMW dealer, the calipers on the M50d actually hold a larger brake pad. The caliper on the M50d is only a twin-piston so it looks like the pad itself is bigger as one would assume the performance of the M50d caliper would not be of the same caliber as the X5 M system, they are a different design.

ASIF they are going to do several rotor sizes. My 40D (which is sold as a sport in Australia) is 365mm rotor on front. The M will have the bigger size, the M50D will have the same rotor.....

The M50d has 385mm front rotors (have measured mine and bought ceramic pads for it), the X5 40d came with 365mm, the X6 40d comes with 365mm in Australia

In Europe the X5 40d & X6 40d has 365mm rotors due to there Autobaun high speeds, also for Europe the X5 & X6 50i comes with 385mm rotors.

The 2008 X5 35d models came with 365mm but the 2009 X5 model was dropped back to 348mm for Australia

The 2007 X5 30d, the first of the E70 series came with 348mm for Australia.

US gets 348mm & 365mm on diesels & 365mm on the 50i models, but that can change for one year to the next.

Its seems to be a bit of a mixed bag, the 30i & the 30d have 348mm rotors and the 40d & 50i have 365mm. As you go up the power scale the rotors get bigger, as mine has 385mm with twin piston calipers wheras the others only have single pot. X5M has 395mm.

Looking at my rims I don't think you could fit 19" rims on, it would be close but I think heat due to lack of ventualtion would be problem, hence 20" wheels are standard.
