NANOSLIDE coating on a Mercedes Benz engine

Sure, maybe it is your grandfather’s car.  But Mercedes Benz is now nano.  Not a nano car but has a nanomaterial.  NANOSLIDE technology involves spraying a thin layer of carbon and iron ‘wires’ on the cylinder surfaces inside of the engine.  How thin?  About 100 micrometers or 100,000 nanometers.  The NANOSLIDE surface looks shiny but it has tiny pores that trap enough oil to lubricate the surface.  The technology reduces the engine weight by 4.3 kilograms which they say saves 3% on fuel consumption.
