List of Volkswagen Group platforms
The German automotive concern, Volkswagen Group has, since the 1970s, developed a series of shared automobile platforms for their motor vehicles.However, more recent platforms have formally departed from this convention, although the older alphanumeric codes continue to be used informally.An example would be the B6 designation - this is used to identify the 2001-2005 Audi A4 (and the related Audi S4), which uses a longitudinal engine and transmission placement with a pressed steel front subframe; however it is also used to identify the sixth-generation Volkswagen Passat, but this uses a transverse engine and transmission placement with a very different cast aluminium alloy front subframe.Platforms developed by Volkswagen Group as joint ventures with other manufacturers have designations which do not conform to the above scheme.In 2007, Volkswagen Group introduced a more flexible "modular component system" architecture on which to base future platforms.
