Thats the big flywheel that generates that effect not the low friction stuff. Needed to smooth out the 3 cylinder balance cycles. Also when you lift off your electronic throttle, the motorised throttle plate is held slightly open for emissions reasons.
The clever part about these engines is their ability to run in Lamba under boost conditions, their dynamic compression ratio is also quite high in normal driving giving a high compression ratio over much a greater driving range.
