BMW 3.0 CSL
The Bmw 3.0 CSL was a lightweight, performance version of the stadard 3.0 CS/3.0 CSi Coupe. It was originally developed in 191 as an homologation model for the German Touring Car Championship by a seperate division within BMW AG. This division was later icorporated as BMW Motorsport GmbH. The 3.0 SCL is generally considered to be the first M series car, although it does not carry the M badge. The "CS" suffix denoted "Coupe Sport", whilst the "L" was added to this version of the 3.0 CS in order to denote "Lightweight".
The car was fitted with an upgrated engine of just over 3 litres to permit further increases in capacity whilst still qualifying for Croup 2 racing, the regulations stipulating that engines can only be enlarged without penalty within their homologated class. Peak output quoted was 200 bhp (SIN) @ 5.500 rpm.
BMW developed four versions of the 3.0 CSL over five years, all to European specifications. The original 1971 model utilized the standard 2,985 cc M30 engine with twin carburetors and was produced only in left hand drive. A fuel injected model displacing 3.003 cc replaced the earlier carbureted version and was produced in both left and right hand drive versions between 1972 and 1973. The final version of the 3.0 CSL, in left had drive only and wth a larger 3,153 cc engine, was built in two distinct production runs during between 1973 and 1975. A total of 708 left hand drive units and 500 right hand drive units were built.
