Team story
Origins
Karl Hall entered Bill Mackey in the 1951 Indianapolis 500 with car number 71. The Hall name consequently appears in the World Championship archive, because Indianapolis counted towards the drivers’ championship between 1950 and 1960. This was an American oval-racing programme, not a team contesting the usual European Formula 1 Grands Prix.
The Formula 1 journey
Mackey secured the last of the thirty-three places on the grid. In the race he completed 97 laps before the clutch shaft failed; he appears nineteenth in the classification. He therefore did not finish the full distance.
That 1951 appearance remained the only World Championship start associated with Hall in the local data.
Historical timeline
Three chapters in the story of Hall
Three episodes to revisit the people, cars and races that shaped this journey.
First appearance · Indianapolis 500
Bill Mackey · Indianapolis 500 1951. The recorded position is P19; this number alone does not show whether the driver completed the race distance. This is the first recorded race start, or the first entry if the team never started a race.
Sporting landmark · Indianapolis 500
Bill Mackey · Indianapolis 500 1951. The recorded position is P19; this number alone does not show whether the driver completed the race distance. This marks the first win or podium where one exists, otherwise the highest recorded placing for this constructor.
Latest recorded appearance · Indianapolis 500
Bill Mackey · Indianapolis 500 1951. The recorded position is P19; this number alone does not show whether the driver completed the race distance. This is the last race start attributed to this constructor in the archive, not necessarily the end of the organisation behind it.
A distinctive way of racing
The designation requires care: Formula 1 records Hall-Offenhauser, while the official IMS history identifies the chassis as Stevens/Offy and Karl Hall as the entrant. Offenhauser is the engine; Hall is the entry’s name. The two ways of cataloguing it do not automatically establish the existence of an independent Hall factory.
What remains
Its record is Mackey’s race, with qualification secured and a mechanical retirement. Comparing IMS with the Formula 1 archive also preserves a characteristic feature of Indianapolis: cars could be remembered by their owner or sponsor, as well as by their chassis builder.
