Which RS4 generation offers most headroom?
The forced-induction ones — the 2.9 TFSI and the 2.7 V6 biturbo — clearly offer more than the naturally aspirated 4.2 FSI V8.
What is the 4.2 FSI V8?
It is the naturally aspirated V8 of the previous RS4, a much-admired high-revving engine. Gains are more modest than on a turbo unit.
What is Stage 2 and do I need it?
Stage 2 assumes mechanical modifications such as intake or exhaust. If your car is standard, Stage 1 is what applies.
