It's has aluminum cylinder sleeves
Anyone know what kind of life those have. Wasn't that what made the Chevy Vega a failure ??? Hopefully the technology today is different.
I found this. Hopefully the new Wing has hyper eutectic-aluminum cylinder bores "When properly finished, hypereutectic-aluminum cylinder bores present a surface to the piston rings that's roughly equivalent to glass [Figure one]. The resulting engine has lower friction, excellent sealing, improved dimensional stability, improved heat dissipation, reduced weight, better recyclability, lower manufacturing cost and higher durability - compared to the traditional aluminum block with cast-iron cylinder liners."
I wonder if "improved heat dissipation" means that the new engine will have round pistons instead of ones that are slightly oval ???
