I'll second Cobram on this.

BMW info here:  http://www.bmw4life.com/nikasil.htm

Some of the first patents on this technology (AKA: Alusil) were from work 
done by GM/Reynolds with a Reynolds 390 Silicon alloy (etched).

Nikasil, was used as I recall, on early Porsche 911/917 race cars and 
manufactured for them by; Mahle. Which was a thin-film coating type technology (As 
BMW later used too).

Later 911/928 cars (and Ferrari) migrated to the Reynolds 390 
silicon-and-aluminum alloy design, manufactured by 'KS' 

Who manufactures many V-Aluminium blocks today including Audi.

KS Aluminium-Technologie AG (ATAG):


A more scholarly look at the technologies can be read here:
