The important things to remember is the S55's 3.0L displacement, inline-6 design, twin-turbos, closed deck block, sodium filled exhaust valves, double-piston high pressure fuel pump, and lightweight rotating assembly.

As stated as the start of the video, the S55 uses 75% of the same parts as the N55, and it's basically just an N55 that BMW modified specifically for use in high-performance application that will see track time.
