Audi S4 B6 powertrain
Replacing the 2.7 litre 'biturbo' V6 engine of the previous generation B5 S4, the new B6 S4 powertrain gained an all-aluminium alloy 4.2 litre, 40 valve (five valves per cylinder) V8 engine (parts code prefix: 079.C, identification code: BBK), with twin chain-driven (at the rear of the engine) two double overhead camshafts (2xDOHC) (two per cylinder bank - 'quad cam'), roller-finger rocker arm cam followers, and included variable inlet camshaft timing. It also utilised a strengthened alloy crankshaft bedplate for the five main bearings, and a two-part baffled oil sump, and a light-alloy variable intake manifold (VIM), containing the sequentially actuated fuel injectors.
