Nice find Deejay!
I think? F1 has been using an air system for some time. It prompted me about another motor I found ages ago... it took some "re-finding"...
A two stroke engine with no pistons (as we know them) or cams...
Pivitol piston I thought the two stroke engine and "Green" technology would never be linked together! I figured the humble 2 stroke engine had both feet in the grave, looks like the Kiwi's put a new slant on things....
