The W116 was the first Mercedes-Benz model to be officially called the S-Class, the start of a long line which continues to the present day. It offered a choice of smooth six and eight-cylinder engines, culminating in the hugely powerful 450 SEL 6.9, as well as a more economical turbodiesel for the North American market.
