Read about XDS a plenty in reviews and on forums too and it's many benefits and all mention just front wheels - On reading the GTD reviews there has been plenty of mention of an XDS + that works on all 4 wheels
Did not see it mentioned on GTI reviews (thought is does have the XDS+) so have the journalists only just found this out? Or is it just me missing it!
Seems as if it will make more of a difference in the wet and even the snow according to this
"The XDS system that was first introduced in the Golf VI was further developed into the advanced XDS+ system for the new Golf GTI. Technically, the XDS+ electronic differential lock is a functionality that is integrated in the electronic stabilisation programme (ESC) for improved vehicle dynamics. XDS+ is an extension of XDS, which is familiar from the previous model; its functionality has now been extended to cover all unbraked driving states. The new system improves agility and reduces the need for steering angle inputs by targeted brake interventions at the wheels on the inside of the bend of both axles. In addition, XDS+ is effective over all conceivable road friction values; it results in more precise handling, even on snow. The well-known benefits of XDS – such as significantly reduced understeer and improved traction – were also perfected.
