Attention: TDR Forum Junkies 
Leave it to those crafty Germans to make a diesel engine lighter, quieter, more fuel efficient and ultimately green with... nano-tribilogy??? From the current Lubes n Greases magazine, page 33:
"It’s all due to an innovative MB-patented technology called Nanoslide, in which “twin-wire arc spraying” is used to melt iron/carbon wires and to spray the droplets by gas flow onto the cylinder surfaces of the lightweight aluminum crankcase. This results in a nano-crystalline iron coating which can be finely finished to a nearly mirror-like, smooth surface, says the German automaker.
For the past five years, Nanoslide was used exclusively in the 6. 3-liter V8s that go into the pricey Mercedes-AMG. With experience now in around 75,000 AMG engines, the coating technology has been extended to all of MB’s series-production V6 diesels. The ultra-fine finish is created by a special honing process which leaves a thickness of only 0. 1 to 0. 15 millimeter. That’s a far cry from the heavy grey cast-iron liners — up to 5 millimeters thick— that are applied in most diesel engines. The honing process also exposes pores in the nano-material which are able to retain oil, and thereby ensure optimal lubrication of the piston assembly, Mercedes-Benz explains.
Daimler AG, Mercedes-Benz parent, is leaning on Nanoslide to help it meet
Euro 6 emissions targets for 2014. With it, the diesel-powered Mercedes-Benz ML 350 SUV can achieve a combined consumption of 6. 8 liters of diesel per 100 kilometers — 24 percent better than its predecessor — and its CO2 emissions have dropped from 235 to 179 grams per kilometer. "
