very interesting ... 4 valve dohc design is nice enough alone but the variable valve timing it has can lead to rather amazing tuning possibilities. swirl flapper valve info and diagrams are a kicker as well...

Very nice! Makes me want to run out and get an SLK350! Now where did I put that $50k I had lying around here...
