As this engine grew, the original "New Generation" sedan evolved through 1600, 1800, and 2000 derivatives. A new CS coupe variation arrived in 1965, combining the 2000 sedan's running gear, floorpan, and some inner panels with a handsome new pillarless body designed by BMW's Wilhelm Hofmeister and executed by Karmann of Osnabrück. Unfortunately, this 2000CS had but a 120-horsepower four and was thus somewhat underpowered, while its face was one only Frau Hofmeister could have loved.
But BMW is nothing if not persistent, and in late 1968 it corrected most every 2000CS flaw in a six-cylinder successor, the BMW 2800CS. To accommodate the longer engine, new sheetmetal was grafted onto the existing body ahead of the cowl, adding 2.9 inches in wheelbase but nearly five inches to overall length.
