Two Piece Connecting Rods

Really interesting technology development for an internal combustion engine....

Interesting! 30% torque is a lot, wonder how much the added compression accounts for. What I see is nylon blocks that lock the original wrist pin. Then lower it below piston skirt with an adapter. If NASCAR starts to use them, their a winner! Until then just another design made possible by computers and CNC. Long rods - short rods it all makes a complete circle!

Yeah, to me it reads as a good concept but "concerned" about developing piston slap and keeping all the rotating/interactive parts concentric.
Such a simple concept. No reason they can't make it work.
As MG notes the race track is the best proving ground.

Looking at their site, with the con rod installed in the piston the top part of the Conrod is nearly static relative to the piston. So you could achieve the same outcome with a tall piston with short skirts and a low set pin. Still going to add weight exactly where you do not want it regardless of how you do it.

"Better Leverage"?
That's bullshit. It doesn't matter what the shape of the conrod is between the gudgeon (wrist) pin and the big end - the "leverage" is the same.
It could contribute to better evacuation of exhaust gases in the second half of the "slowing" exhaust stroke and first half of the "accelerating" induction stroke - giving higher effective compression. Under these conditions the conrod will "straighten", otherwise will be "bent" (either due to compression or inertial forces) hence slightly shorter.
I don't think it will affect piston slap at all, unless you assume torque is applied to the piston through the gudgeon (wrist) pin. I don't think this will happen.
Interesting concept though!
