What is the 2.7 V6 biturbo?
It is the twin-turbo V6 of the earlier S4 generation, a much-admired engine with genuine tuning headroom. It is covered in our catalogue.
How does the supercharged 3.0 TFSI respond?
Very well. Forced induction gives it real headroom, and it is the most represented engine in our S4 catalogue.
What is Stage 2 and do I need it?
Stage 2 assumes mechanical modifications such as intake, exhaust or intercooler. If your car is standard, Stage 1 applies.
