By 1934, the French government established various restrictions on commercial vehicles,[1][2] among them a decree that imposed limits on design, including: the overall width of a road vehicle should not exceed 2 metres 35 centimetres and the overall length 10 metres.

In September 1934, the company unveiled a forward control truck for 1935 at the Paris Salon, the ABF (5-tonne payload truck),[1][2] and announced a second, the ABG tractor unit (hauling capacity of up to 10 tonnes), which was unveiled at the Brussels Salon in November of that year.

In 1937, the French military commissioned a couple of ABFs adapted to use natural gas as part of a push for alternatives to petroleum-derived fuels.

[1][2] The Societé Algerienne des Transports Tropicaux, a company focused on trans-Saharan travel, commissioned ABGs bodied as mixed vehicles with a second row of seats in the cabin, which was lengthened accordingly, making them able to take three to four passengers.

The ABF and the ABG have the same inline-four engines: a 5.9-litre petrol unit and an 8.4-litre diesel, both delivering 85 metric horsepower (63 kW)[8] at 2,000 and 1,600 rpm respectively.

[1][2] It was initially powered by the same petrol engine mounted by the ABx, delivering a power between 85 metric horsepower (63 kW)[8] and 99 metric horsepower (73 kW) at 2,400 rpm.

[13] After World War II, Renault introduced a ZP-based bus/coach called 215 D (later renamed as the R-series).
