AAAWWWWW! Not another VTEC!!!
Understeer is when you hit the wall with the front of the car
Oversteer is when you hit the wall with the rear of the car.
Horsepower is how fast you hit the wall
Torque is how far you take the wall with you -

That is amazing. The idea of a variable length intake manfold is very smart. Shorter in the low RPM's for more TQ, higher in the upper RPM's for more hp. I hope this catches on with other car maakers.There is a video somewhere that is pretty cool.
I believe shorter runners would make more power up top, and longer down low?

I wish there were some engineering drawings showing how this system worked. The variable length intake runner stuff isn't new.. although i can't think of an application off hand.
The continuously variable valve lift and cam phasing are interesting and a definite departure from how VTEC used to work. Note that AVTEC is not the first introduction of continuously variable valve lift into a production engine... Valvetronic from BMW has been doing this since 2002 or so, and I wouldn't be surprised if they weren't the first.
I've heard that F1 engines use pneumatic valve trains.. i wonder if/when we'll see that in production cars. If anyone has links to drawings of how these systems work, that'd be fantastic.

Volvo I believe will be the first company to market w/ Pneumatic valves. Garberg would probably know more.
