Renault AH series
Light/Medium 4x2 Truck, about c50,000 built 1941-47
Introduction
The Renault AHx was a series of light to medium-duty trucks produced by Renault between 1941 and 1947 under German supervision, assembled in Boulogne-Billancourt, France. Producton entirely went to the Wehrmacht, and a few to the Kriegsmarine and Luftwaffe. The Renault AHx series represents a fascinating intersection of wartime exigency and automotive evolution and was emblematic of industrial adaptation under occupation—continuing production under German command. The efficient cab-over design predated and influenced post-war commercial truck development. Many were repurposed for civilian use after the war, bridging the gap into modern Renault commercial vehicles.
AHS: Light-duty version, ~2 tonnes payload. Equipped with a 2.38 L inline-four engine (~52 PS). Gasifier versions (AHSH) offered ~35 PS
AHN: Medium-duty, around 3.5–4 tonne payload, using a 4.05 L inline-six (~75 bhp). Also available in gasifier form (AHNH) at ~52 PS
AHR: Heaviest model with ~5 tonnes payload, similarly equipped with the 4.05 L inline-six (~75 bhp) and also offered in gasifier form
Development
Renault introduced forward-control cab designs in the 1930s, which continued into the AHx series. These trucks were developed as simpler, more economical successors to the pre-war AGx/AGR range. The story of these vehicles can be summup as "born in freedom, built under occupation". In the mid-1930s, Renault received an order from the French army for the Renault AGR in 1937. This small 3.5-ton payload truck was appreciated by the army, which purchased several thousand. But in 1939 and the invasion of Poland, France went at war, prompting the army to order new vehicles. From June 1940 onwards, France was occupied and experienced difficult times. All the French industry was forcibly pressed to take part in the German war effort. At Renault, the Boulogne-Billancourt factory went under German supervision to continue production of utility vehicles, including the band new Renault AH series.
The Light One: Renault AHS
The Renault AHS prototype was presented in December 1939 (pinterest). It was developed to replace the Renault AGC for the French army. Its unladen weight was 2,480 kg and payload 2,500 kg but remained a single prototype, not selected for production. Series production started under the occupation from August 1941 and went on until March 1944. As the smallest in the series, it measured 5.60 m for 2.03 m in width, 2.41 m in height. It was only available as a cab version with a dropside platform, roll bars and tarpaulin, usable length 3.51 m by 1.86 m on the flatbed, dropsides 0.60 m high.
Its unladen weight was 2,400 kg with a payload of 2,000 kg. It was powered by the 1937 Renault Primaquatre 603 4-cylinder petrol engine of 2,383 cc rated for 46 hp at 2,800 rpm, coupled with a gearbox with 4 forward speeds and one reverse, 1:6.83 single reduction axle. Top laden speed was 60 km/h, fuel consumption 22 liters per 100 km. Total production was 7,985 units. No hooded cab but a cab-over with sloping flat face. This was the most produced of all three variants.

The 5t variant: Renault AHR
The Renault AHR prototype was presented in December 1939, with an unladen weight of 3,940 kg and payload of 5,000 kg. It remained a single prototype, not selected for production. Series production started in April 1941, until March 1943. This later production version measured 5.60 m in length, 2.03 m in width, and 2.41 m in height. This cab-only version had a 60 cm dropside platform, roll bars and tarpaulin. Its unladen weight was 3,860 kg, payload 5,000 kg. It was powered by a Renault 4,086 cc 6-cyl. gasoline engine rated for 75 hp at 2,800 rpm, 4-speed forward, 1-reverse gearbox, single-reduction axle. Top speed was 60 km/h fuel consumption 30/35 liters per 100 km. Total production unknown (archives burned in July 1944).
They had the largest wheelbase of the AH series, (4.44 metres instead of the 3.73 metres of the AHN). The petrol version achieved a top speed of 60km/h, of which only 42km/h remained with the gas generator. The gas generator was placed directly behind the cab, limiting the possibilities for coachbuilders. This installation used 76 cms of the vehicle’s length, leaving 3.58 meters of structure space, while the petrol version kept 4.30 metres (5.00 metres for the AHR). The rear axle was doubled (four tyres total) unlike the AHS and AHN. And the rear flatbed, all metal, had six diamonds instead of five on the AHN. The frame remained the same apart with an extra arch.
The AHR used the well-known "85" engine (for 85mm bore). Like the AHN, the AHR were equipped also had the 6-cylinder of the Viva Grand Sport displacing 4,086cc for 75hp at 2,800 rpm. For the trucks retained in Vichy service for the military, or in civiloan service under derogation, fuel shortage meant they were all converted during wartime production to received gas generators to run on charcoal. This however trigerred a considerable reduction in power with the 6-cylinder downgraded in effect down to 52hp, and thus, too anemic to carry its max load. This was a mixed installation as the generator came with a 10 litres petrol tank and 75kgs of charcoal. Yet they consumed 45kg per 100km making for a range of 150k ms half than when using gas.
In wartime, for the civilian market in the free zone, all Renault AHR ran on wood gasifier and finally with Renault-Imbert wood gasifiers, easily recognizable by the pre-cleaner protruding horizontally at the front of the vehicle. There was also a gas cooling radiator arranged flat on the front grille. These 6-cyl. engines only developed 52 hp, twice that of the 4-cylinders.
The Renault AHR differed profoundly from its predecessor by having no hooded cab and instead a semi-forward cab with sloping flat front. It was produced on the same line as the AHN and AHS, but offered the highest payload. The cab ahd completely flat body panels common to the other two, the grille had simple horizontal bars, tere were buried in small round headlights, no bumpers, four sections windshield with upper sections opened by the driver and passenger in the summer for ventilation.
Given its late arrival, as the SAET had yet ordered, on March 14, 1940, six AHR to Vincennes for testing and actual use, they never had time to be deployed in numbers. Its use by the French Army was pretty limited, and most units that awaited it still in May 1940 never received the vehicle. This was also part of the chaos of manpower, with many drivers found having no vehicles and many trucks without drivers. Subsequentely these vehicles remained in parks, iother in rear line depots, oe at the factory parking itself, and were captured intact by the Wehrmacht.
As a way of consequences, they ended all German service in pristine conditions. Even those in the French Army had little time already to be worked out, and many were captured dry of any fuel, unsabotaged, unburned. They were used by order of the Heeresversorgung in regular roads, given their lack of off-road capabilities, and thus, if many were sent on the eastern front from late 1941, they quickly showed their limits, notably their absence of equipments to cope with very cold temperatures (preheater, cold starter etc.) and suffered badly as a result. In German service they all ended with a notek light, installed on the right side generally and in some case, had welded frames for tooling boxes, strappings for shovels and pickaxes for Intendantur teams, as well as jerrycans. Since they were road-bound they mostly served between railway hubs and rear line depots whatever the front.
It should be noted that Billancourt considered two vehicles derived from the AH range, like the 6x2 derivative of the AHR 1 with for a 6 tonnes payload. The frame remains was the same, just elongated to receive a trailing axle behind the driven axle. The prototype was named AHZ but ran with a gasifier in March 1941 for trials, and if production was not ordered, it was kept by the factory to facilitate wood supply. There was also the 6x4 210 H, fitted with a Renault-Imbert gasifier and pre-cleaner at the front overhang with a flatbed AHN 1/AHRH l body but rear axles with single wheels. It was tested in March 1945 but never produced either.

The intermediate: Renault AHN
Renault held a prominent position with the AGR before it developed a new military vehicle, simpler to produce and inexpensive, to replace it. The first prototype was presented in February 1940 as the AHN, barebone and dumb simple with its flat surfaces, flat cab, no protruding hood, and sloping forward to the point it was called a "semi-forward cab" or "semi-COE". The payload was good at 4 tons, heavily inspired by AHR presented at the end of 1939.
The Renault AHR had for main difference had a longer wheelbase (4.44 meters instead of 3.73 meters for the AHN). The petrol version here reaches a top speed of 60 km/h, while for the gas-powered version the top speed is only 42 km/h. The equipment has been placed directly behind the cab, which reduces the loading length, and occupies 76 cm of the vehicle length. This leaves only 3.58 meters of the bodywork length, compared to 4.30 meters for the petrol version (4.30 versus 5.00 meters for the AHR).
It received Mines approval on February 14, 1941 and thus, production was monopolized by the Wehrmacht from March. The first sub-version was the Renault AHN1, but its payload was reduced to 3.5 tons. Its engine was a four-liter six-cylinder rated for 75 hp, enough for 59 km/h. It was also ordered by the Vichy regime to replace its elderly fleet requisitioned by the German army.
In May 1941, a gas-powered version was added to the AHN1 offering as the "AHNH1" (only 271 produced until December 1942) for the civilian market but without a gassifier, so it could not avoid the gasoline shortage, ending rapidly or converted. The first series AHN (AHN1) went until July 1944, with 15,610 vehicles, with their headlights embedded. Production remained low due to the bombings at Boulogne-Billancourt, and workers sabotage, notably by depositing sand in the engine casings. German denomination was Renault Lastkraftwagen 3.5 t AHN.

Models & Production
Wartime Production: Initially intended for the French military, the AHS prototypes appeared by 1939, replacing the AGC. After France's occupation, the Wehrmacht took charge of production and used these vehicles under designations:
AHS as Lastkraftwagen 2 to (2 tonnes)
AHN as Lastkraftwagen 3.5 to (3.5 tonnes)
AHR following suit for heavier payloads
Production Volume Estimates: Approximately 23,000 AHS, 4,000 AHN, and 1,000–2,000 AHR were produced and supplied to the Wehrmacht. Post-War Use: After WWII, updated versions (AHS3/4 and AHN2/3) were produced for civilian markets. In 1947, the AHx series was replaced by the Renault Galion. Additionally, the AHx cab design influenced the later Renault 208 E1, a 7-tonne payload truck.
The AHN led to sub-variants such as the Renault AHS-1 (Feb. 1942 - July 1944) gas-powered with the same engine but gas generator type 703 reducing power to 35 hp at 2,800 rpm, payload 2,000 kg. The rear axle ratio was 5x43 for a top speed of 51 km/h unladen, 48 km/h laden, and a limited production of 347 vehicles.
The other sub-variant was Renault ASH-2 (Sept. 1944 - Sept. 1945) same as the ASH 1 but woth a full gas generator, power output 35 hp, with new headlights and steel wheels replaced by artillery-style wheels (common on the AHN). Production was limited to 275.
The Renault AHS-3 (Nov. 1944 - June 1946) was an "Updated" liberation version of the ASH 1 Produced to 6,253 units. It was replaced by the Renault AHS-4 (March 1946 - February 1947) postwar, with a lowered platform requiring modified wheel arches. Production: 3,700 units. For the basic model, the Germans registered it as the Renault Lastkraftwagen 2t (1941-1944) with a pproximately 23,000 all AHS types combined.
For the AHR, the largest, the majority was intended for the German army, with exact numbers estimated around 1,445 vehicles produced, plus 2,000 for the German army between 1941 and 1944 based on plate numbers. After the liberation, production stopped in accordance with the requirements of the Pons Plan, with assigned Renault the manufacture of 3.5-ton trucks only. There was a Gas-powered version with a power output of 52 hp at 2,800 rpm and top speed of 40.9 km/h (25.4 mph) unladen. Production owas just of 142 vehicles used by the civlian sector in France. Surviving ones were converted back in 1945. The other sub-variant was the Renault AHZ (from March 1941), a 6x2 variant adding a second axle on the extended chassis of an AHR for a payload 6,000 kg. Single prototype, which was used inside the factory for internal transport of parts.
For the AHN, the first series was of 15,610 vehicles from February 1941 to July 1944, before bombings stopped it. It was resumed by November 1944 after the liberation of the Billancourt plant by the Allies. Renault then launched the AHN2, reserved for the French war effort, and then surplus were sold on the civilian market. Modifications were minimal and there was a total until June 1946 of 8,400 units, plus in parallel the gas-powered version AHNH2, produced between October 1944 and May 1945 with 211 units. From June 1946 appeared its ultimate evolution, the AHN3 with a dropside platform lowered by 22 cm, length reduced by 12 cm, width increased by 12 cm, manufactured until January 1947, with c2,000 for the civilian market. It was replaced by the Galion.
The Lastkraftwagen AHx in service
As we saw earlier, production of the Renault AH was almost entirely focused on the needs of the Wehrmacht, including a few used by the Lufwaffe and by the Kriegsmarine for specific needs. The simplicity of the vehicle interested German autorities, that saw its potential for arge productions in order to replace lost vehicles, but its limitations were also well understood. They were supposed to have been military vehicles, but were not designed for off-road use and only integrated tooling and stowage bins. They had no winch and stuck to good roads for their service, used in France and throughout occupied western and easter Europe, but rarely in Russia given its limitations.
