The BMW New Six CS (internal name BMW E9) is the two-door sport coupé in BMW's New Six line, produced from 1968 to 1977 alongside the four-door E3 sedan. It featured straight-6 engines of 2.5, 2.8 and 3.0 litres in road form, with larger units used in racing. It was successful in racing and helped establish BMW's status as a sporty driver's car. The CSL model is very collectable today.
