I have a line on an awd s40
What would you think about making the only awd focus Xr5 in aus?

Volvotech

My Son's & I have said it would be great to convert an xr5 to Awd too it would be epic.

I'd love to do it but I feel it will distance me a little from the (potential) customers I'm trying to market to.
It might be a project to tackle a bit later on, potentially with another vehicle as the starting point.
The S40 (or V50) AWD would be the ideal donor for it though.

I know of a Mondeo XR5 with an AWD conversion in progress.

There's a HEAP of work involved in getting the Focus RS front and rear subframes into the XR5 in order to gain track width and better front end setup. I cannot imagine it being a great deal more difficult (if at all) to go AWD using an S40/V50 donor.

Are there standalone haldex controllers or do you have to swap all the Volvo ecus over?

Its just simply an on off thing, there is no "Split" to control
As such you could easily tie something into the CANBUS to monitor traction loss% and a few other parameters and decide if it should be on or off...

I thought gen 3 Haldex and onwards had more logic than just reacting to slip?

In other applications... YES... in the Volvo one... no, just because of the design of the system...
The setup of the system is such that the drive shaft is always fixed 1:1 with the speed of the front diff (effectively always locked center diff) and the Haldex physical unit just serves to lock the shaft to the rear diff or let it spin free

The difference in the generations is that the later gen3 cars got the electric fluid pump which keeps the pressure in the clutch mechanism up even when the drive shaft is not spinning so the system works even from a dead stop
the previous systems depended on rotation of the drive shaft to generate fluid pressure to engage the system
Thus in earlier cars the system could not engage from a dead stop to prevent slip, only to try and stop slip after the car was already moving

@AshDVS sorry for dumping all this in the vocus thread, maybe should be split into an "Make my P1 platform car AWD thread"

By logic I meant inputs from steering wheel and yaw sensors to pre empt the need for awd, I'm sure I've felt it working this way on a particular hill & corner I drive often near my place.
Maybe, maybe not

A couple of posts in another thread turned into some constructive thought and discussion around converting a vehicle on the P1 platform to AWD.

Thinking about a building a Frankenstein C30 T5 AWD or LS-LV Ford Focus XR5 AWD, this may very well be the place to look .

It'd involve an S40 or V50 AWD donor car, but might just be what you need to read to build the gripped-up pocket-rocket of your dreams.

C30AWD is definitely something I would do.

The C30 polestar is AWD

C30 Polestar is one of the few Polestar variants that is actually REALLY impressive.
Definitely need the Polestar front guards for it!

It's dumb
Blame volvo as the system is really just designed for low traction environments like snow or mud

I keep thinking my s40 should become fwd and a c30 should become awd

sucksqueezebangblow

I thought gen 1 and 2 Haldex were reactive and gen 3 onwards are proactive having the electric pump pre -pressurising the system

Philia_Bear

Gen 3 can just turn on and lock while car is at a stand still, that does not mean it turns it on if you say try to launch it... it requires that there has been detected slip within the last 10-15 seconds to engage

sucksqueezebangblow

Weird, if I hit this steep corner at speed and turn in hard I don't get any inside front tyre spin at all and it feels like the rear had become activated

I’m going to revive an old thread here as this is a project I’ve spent the last 2 ½ years researching and is very near and dear to my heart. Ash knows me from the XR5 Forum and my obsession with LV XR5’s and AWD platforms.

Over that time I’ve bought two TE Kuga stats, wrecked & rebuilt at least a dozen XR5’s, rebuilt a stat Focus RS MK2 as a track car and last year picked up a S40 T5 AWD 6sp repairer in the name of research. I also have a seriously built forged T5 engine that last time it ran made nearly 500hp and is about to go to the engine builder again to get more work done.

I’ve spent 100’s of hours searching the net looking at Volvo’s, Focus’s, Audi’s and anything remotely related to gain an insight in how to make this work. I have most of the parts required with the last few turning up this first quarter 2017 and then hopefully I can start the build. I’ve got a detailed build spec I’m working to and at the moment I’m down to two main issues that need resolving – fuel pump control module + sender units for fuel gauge, and a rear LSD.

Let the fun begin ?

What are you putting the awd into?

All sounds awesome. Just not sure how it gives a better outcome than just modifying an AWD S40/V50.
