The BMW type E9 was produced from 1968 to 1975, the last coupés were delivered in 1976. The first version is the 2800 CS that replaces the 2000 C / CS range. It differs by its front, due to the extension of the engine compartment to accommodate the new inline 6-cylinder inherited from the 2500/2800 sedans. This engine, type M30, will do a lot for the fame of BMW. His last descendants will be the engine of the M5 in 1995. As for his predecessor the chassis E9 is assembled at the site of the famous coachbuilder Karmann. The E9 type has been expanded over the years by several engines: the 3.0 CS carburettor replaces the 2800, and the 3.0 CSi adopts the electronic injection.
The 2.5 CS makes its appearance in 1974. It is the last of a lineage that will be replaced by the BMW 6 Series.
