Everyone I've spoken to who is remotely mechanically minded (ie not me!) says the current crop of bi-turbo engines are fiddly fail prone things.
Not quite sure why VW would want to push 240ps like that, when the current proven design will definitely go there anyway (as DTUK and friends prove easily!).
Some other interesting new bits of VW (Bosch!) technology on that page though, you can see that the truly smart car is only just around the corner.
