Happy 40th birthday to BMW M Division

BMW 3.0-litre CSL

In the beginning, there was this - the 3.0-litre CSL.

It was a homologation special built by the manufacturer's racey subsidiary, BMW M, so the car could compete in the European Touring Car Championship.

Established in 1972, M only had eight staff, and this was its inaugural project. The CSL was lighter than the standard E9 by using thinner steel to build the body, shaving off the chrome chintz, binning the soundproofing, fitting alloy doors, bonnets, and boot lids then replacing the side window glass with Perspex.
