absolutely every company has one of those. I'm familiar with the bmw one: VANOS something. from the 90s. variable compression is nothing new, just very prone to failure. the other downside was it was much harder to work on the engine, but nobody cares about that anymore.

No, that's totally different. That's just variable cams(e.g. what Honda calls VTEC). This is actually changing the combustion chamber geometry.

  so a lot more complexity to just change the volume inside the chamber in another way?
