coupe family were

The first members of the 6-Series coupe family were the 630CS and 633 CSi. Like the 3.0CS and CSi that preceded them, the new coupes featured bodies by Karmann and were very easy on the eyes. Eventually, body production was taken over by the parent company, but by then the stylish shape of the coupes had been well defined. All versions of the first 6 Series were built on a platform similar to that of the 5 Series and powered by variants of the BMW inline six engine. The first offerings of the series offered modest performance with a 176-horsepower 3 litre providing the muscle. One of the last, the M6, was a lot more entertaining with 256 ponies on tap and a performance-tuned suspension that helped ensure the power could be put to good use. In 1989 the first 6 series was discontinued, and the new 8 Series became the sole offering in a coupe configuration.
