Jo Vonlanthen was a Swiss racing driver whose career on record comprises a single Formula 1 start for Williams on 17 August 1975. He failed to finish the race owing to engine failure and scored no championship points. He raced at a time when opportunities in the sport's top category were limited for drivers without substantial backing or connections to established teams, and his solitary Grand Prix appearance represents the sum of his documented professional involvement at that level.[1]
Vonlanthen's rating of 2,946 places him among amateur and club-level competitors; the absence of multiple races, points finishes or head-to-head records against established rivals in the record means his standing cannot be assessed against stronger professional fields. What racing preceded or followed his 1975 Formula 1 entry is not captured in this database's records, though contemporary sources suggest activity in lower categories such as Formula 2 and Formula 3 during the early 1970s.[2]
