Not seen this idea before & it may be a load of BS. Apparently Porsche are developing it.

You would think they would be spending all funds on EV technology these days, based on what politicians tell you.

Looks a large degree of eccentricity if it’s real.

Doesn't strike me as practical. Perhaps they can make it work, but the Freevalve idea seems like a far more practical way to achieve variable compression.
