Which engine offers more headroom?
The 4.0 TFSI V8 biturbo, clearly. Being forced-induction, there is boost pressure to work with, which does not exist on the naturally aspirated V10.
What is the 5.2 V10?
It is the ten-cylinder naturally aspirated engine of an earlier S8 generation, closely related to Lamborghini's V10.
Is the work reversible?
Yes. We always keep the original ECU file, which matters particularly on a car in this segment.
