Anyone want to guess what this could entitle in terms of effected components and material?
Lightweight materials in "high-rpm parts of the powertrain"
Crankshaft, Pistons, Valves, Camshaft, Turbos, Transmission are a few high rpm powertrain components I can think of. I wonder what materials not already used in the standard engine he is eluding to, titanium sounds too expensive.
