The clear lines without any additional features and the outstanding spaciousness, like the top-of-the-range W 108/109 saloons, were designed by Paul Bracq. Four- and five-cylinder petrol and diesel engines were given the model number W 115, whereas the large six-cylinders and the Coupé which was built from 1969 onwards are classified as W 114 – and popularly known as “Stroke Eight” after the year 1968 when they first appeared. The “Stroke Eight” was given front disc brakes as standard, double wishbones on the front axle and a modern diagonal swing rear axle. The interior showed changes too, with head restraints front and back, automatic seat belts and a centre console that still influences the style of today’s models. And for customers who found the boxy shape with the drag coefficient of a garden shed too minimalistic, from 1969 the two-door version was available without a B-pillar and with a sloping windscreen and more sophisticated equipment.
