Vaq electronic controlled diff lock

[Melon Head]

Has anyone had a chance to give one of these new cars a thrashing in the twisties to compare XDS vs VAQ?
Is the VAQ a TRUE diff lock or just another version of XDS?

Just came across this:
"A VAQ-equipped Golf has already lapped the Nürburgring eight seconds faster than prototypes with a conventional diff." - autocar.co.uk
