[1] Three trucks were built with normal control (with the cab behind the front axle); the fourth was built with forward control (cab-over-engine design (and sleeping accommodation)).

The trucks were intended for off-road use, in the oil and mining industries, in particular petroleum exploration in the Sahara.

The trucks were designed and built in secret, and with a tight deadline; the first was finished after nine months, at the factory in Courbevoie.

It was then shown at various other car shows - Lyon, Avignon, Helsinki, Casablanca, Frankfurt, and Geneva.

The second T100, having worked in Algeria, was later returned to the Berliet Foundation's museum in 1981.
