ARL V 39
Designed as a self-propelled gun for the DCRs, the Infantry's armoured divisions, 72 ARL V 39 (including 24 unarmed command variants) were ordered on 15 October 1939 to arm 8 battalions each with two batteries of 3 vehicles (two battalions per DCR). On 9 May 1940, the order was increased to 108. The ARL V 39 was to have 50mm armour and be armed, like the SAu 40, with a new "high power" APX 75mm gun of which only two prototypes existed, both mounted on the SPG prototypes. None were produced other than the single prototype, evacuated to Morroco and abandoned there.
Derived from the 1929 fortress gun (itself a development of the old 1897 field gun) with a semi-automatic breech and an automatic loader added, the "high power" APX 75mm gun fired a mle 1915 HE round with a reduced charge at 400 m/s and the mle 1915 AP round at 570 m/s (50mm penetration at 1000 m) and its two sights and stereoscopic rangefinder allowed a direct fire range of 2000 m. Horizontal traverse was 7° to the left and 7°6 to the right, -10° to 30° vertically. 200 rounds were carried. One original feature of the gun was the fact that the barrel could be retracted inside the hull to reduce the vehicles length when moving.
FCM F1
Twelve of these 140 tonnes behemoths were ordered on 27 April 1940 to replace the aging FCM 2Cs. This tank, designed to lead assaults on the Siegfried Line in 1941, was to be armed with a high-velocity 90mm gun (mv 710 m/s, penetration 100mm at 1000 m) in the rear turret and a 75mm SA 35 in the front turret (the mock up above shows a 47mm gun mock up instead) with a 25mm AT gun on each side of the hull ! The design wasn't finalised however and armament variants included a 105mm gun in the forward turret of in the front hull. Its front armour was to be 120mm with 100mm side armour and its two 550 hp engines would hopefully allow it to race along at a mighty 24 km/h...
Renault G1R
The 1936 requirement for a D2 replacement in the "battle tank" role called for a 20 tonnes tank, capable of 40 km/h, with the armour of a B1 bis, a 47mm SA 35 turret gun and a hull-mounted 75mm gun. However, Renault's design evolved into a 35 tonne tank with a turret mounted "high power" APX 75mm gun... which was rejected on 14 May 1940 because it was too far from any official requirement !

Chevrolet developed an armored car that would have excellent cross country capabilities. It was also intended to replace the M8.
Was standardized in March 1945.
