the VR6 is to heavy would make it much to nose heavy, which would completely ruin the concept of a modern light vehicle.
Currently confimred are only the 1.4TSI with different power ouput some diesel versions and a 200hp 2.0l TFSI. VW currently thinks about a topversion with a 250hp 2.0l TFSI engine most likely called Scirocco R250.
BTW the Scirocco starts its race carrer befor going on sale. VW race the next 24h at the Ring with 3 factory Scirocco raced by some well known race drivers like WRC world champion Carlos Sainz, 3time 24h of the Ring winner Hans-Joachim Stuck, Ginelle de Villers, Dieter Depping etc.
VW hopes to repeated the GTI´s last years sensationell 8th place overall(and overwhelming class victory) with their Golf GTI..the 24h Scirocco shares the whole technic of the last season GTI.
At the same race the Scirocco Mk I started Volkswagen touring car racing history.
