Arai has a very good point about using that engine. It is clear they want to be the fastest. The trick rear wheels is a bit speculative. The engine will be at least a 1.6T or 2.0T. The HP will be in excess of the rivals which is currently 265HP. This points to something very promising. It also indicates the 2.0T to be the likely candidate, that power may be a bit keen for a 1.6T to achieve without pushing it too far.
