One electrically decoupleable sway bar (for 4WD applications) and an active one (for SUVs).
Porsche Cayenne, BMW X5 and X6 come with optional active sway bars.
Remember many SUVs usually have huge sway bars of 40 mm and more due to their high center
of gravity. Normally this leds to increased "copying" of the road surface which passengers feel as
they sit high in these cars. An active sway bar is soft in straight direction while hard in corners.
You're right - the 991 Carrera comes with "Porsche Dynamic Chassis Control (PDCC)", a similar
active sway bar system.
BTW, the new 991 GT3 even has an active rear steering giving some "toe out" in tight corners
and increased "toe in" at higher speeds.
