Along with cams that are, for the lack of the engineering term, spheres linked so as to push the cam a bit, and it has a totally different lobe profile. A gut invented those and is trying to market them so as to retro fit them to existing engines.

Great Idea just a decade too late.
+1 vote. I belive F1 engines use a version of this technology, pneumatic vavles with no valvetrain and no camshaft.

i know one of the newer BMWs (M5 maybe? ) uses a system like this.
