Bracq's clean-lined six- and eight-cylinder saloons.

The range ran from carbureted six-cylinder 250 and 280 models to fuel-injected SE and long-wheelbase SEL variants, then to the 3.5-litre M116 V8 of the 280 SE 3.5 and SEL 3.5, and finally to the North American 280 SE 4.5 and SEL 4.5 with the larger M117. Crumple zones, improved suspension, and a more modern cabin marked a clear step forward from the Heckflosse cars it replaced.
Between 1965 and 1972, 359,819 were built.
