2995ccm V6 FSI Roots Kompressor
333ps
420Nm
0-100km/h: 5.4s(manual)
S Tronic will be 0.2s faster but, we need to see will it be in the offer from the start.
Regarding S5 it will use 4.2L V8 till end of its model life. Maybe some power/torque increase in MY2010...
Same engine will go also in A6 with 290ps.
