Iveco / Magirus 90-16 (LWR) new conversion kit C.HEL.24N.RSOL-24 for 24 volt vehicles

The Club of Four was an alliance of four European truck manufacturers: Saviem, Volvo, DAF, and Magirus-Deutz.

Officially called the Société Européenne de Travaux et de Développement (ETD), the team was based in Paris. Founded to develop a shared range of light trucks, its main success was a shared cab design. Cabs can be one of the most expensive parts of a truck to design and build; the alliance allowed one cab design to be shared among four different truck manufacturers, allowing economies of scale. In 1978, Saviem was merged with Berliet to create Renault Véhicules Industriels (RVI), but the new company continued as a member of the Club. Magirus-Deutz became part of Iveco.

The cab was used on a wide range of different trucks. It was even used on Mack trucks in the USA. It remained in production for almost a quarter of a century. Although initially intended for medium trucks it was also used on light trucks, even the 6-tonne Magirus 90M6FK.
