The Renault factories tested large numbers of ADC's between 1922 and
1934 which were to shape the standards applied to their future models.
The 15 fist VH-type ADC's, single-bodied and reversible, were fitted
with a four-strocke, V12-cylinder diesel engine and a 4-speed gearbox
and were rated at 162 kW at 1500rpm. They were used on the Est, P.O.,
PLM and AL networks, followed by around a hundred other models,
including the VH 2211, at 195kW a more powerful machine.
