During the 1952 edition of the Carrera Panamericana, eventual race winners Karl Kling and Hans Klenk suffered a bird strike incident when the Mercedes-Benz W194 was struck by a vulture in the windscreen. During a long right-hand bend in the opening stage taken at almost , Kling failed to spot vultures sitting by the side of the road. When the vultures were scattered after hearing the virtually unsilenced W194 coming towards them, one vulture impacted through the windscreen on the passenger side. The impact was enough to briefly knock Klenk unconscious. Despite bleeding badly from facial injuries caused by the shattered windscreen, Klenk ordered Kling to maintain speed, and held on until a tire change almost later to clean himself and the car up. For extra protection, eight vertical steel bars were bolted over the new windscreen. Kling and Klenk also discussed the species and size of the dead bird, agreeing that had had a minimum wingspan and weighed as much as five fattened geese.
