...for those of you fortunate to have already ordered a new GTi, was it performance pack or not?? Seems rude not to, imho,

should be first box ticked

Yes, it's not just a bhp thing

Factory slip diff and 10PS more for £980, bargain if you ask me!

[Gti Fly]

Bigger/better brakes too

[timbomfg]

Oh fair nuff, didn't spot that when playing with the configurator. I wouldn't mind knowing who makes the diff or whether it's a home-grown affair. I'd guess Peloquin tho.

Pity i'm not a fan of the rear end of the car. Be nice if they would give those options/engine on the estate!

The front diff is electronic,  and from what I've briefly read it looks like some sort of haldex type system (clutches, hydraulically controlled via ecu).   So it's got a series of clutches and an ecu which loads up the clutches and controls the amount of lock up between the front axles.

From what i've read, they specify it as a mechanical LSD. The eDIFF style you mention isn't really any different from the version we have on the MKIV on the later ABS controllers no?

Ediff works differently to ESP I think, as is doesn't cut power it brakes the spinning wheel to redirect the power to the wheel with grip

They put them both round the ring, the one with the pack was 8 seconds faster than the standard! How's that for throwing a few goodies in

Wow, that s big difference!

Here found some more info to help explain it better than I did:

http://drivelinenews.com/news/electronic-locking-differential-for-vw-golf-gti-mk7/

 

Volkswagen’s new Mk7 Golf GTI, due later this year, will be available
with an optional performance pack which includes the “VAQ” differential
(front axle transverse differential lock) in the front (driven) axle.

Unlike the electronic EDL or XDS traction systems, which use a
standard differential in conjunction with individual electronic control
of the front brakes, the VAQ is an active mechanical clutch pack-based
device located between the differential cage and the right-hand drive
shaft. The pressure required to actuate the clutch pack is produced and
regulated by an electrically-powered hydraulic pump. The VAQ is a Haldex
unit similar to that already used in VW 4MOTION four-wheel drive
systems.

8 seconds over the bridge to gantry on the NBR its really that much to be honest with you.
