I found this pretty cool.   a lot of economoy car tech will come from this.

 

~45% improved hp and tq purely based on true variable valve timing.

Those are some pretty crafty Germans. Very cool stuff. 

Swed's haha.  Germans hat.

An even craftier people. Just imagine the infinite amount of engine tuning you could do with vvt and a vgt turbo. 

I can't believe nobody has come up with this until now. The tuning and performance possibilities are endless if they can make it reliable.

Ever seen any info on rotary valves?  

Only as it pertains to the Rotax 2-stroke engines. They used rotary valves in their snowmobile engines and a lot of their aircraft engine applications, I believe. They seemed to work fine, but I believe they have gone back to the more conventional reed valves in their sled engines...but don't quote me on that. I was never much of a Ski-Doo fan...! I'm more of a Polaris Pro and Arctic Cat M-chassis fan...and I've always run V-Force reeds in my sleds.
