Gun: 120mm L11 with autoloader
Crew: (commander, loader, gunner, and driver)
Weight: 46 tons
Suspension: Hydropneumatic
Engine: MT833 1000-1200 hp engine (MBX 833 RA-500 750hp engine or Saurer 500 hp engine (for balance purposes))

Power-to-weight: 21,7-26 hp/t (16 hp/t with 750hp engine and 10.8 hp/t with 500hp engine
Armor: Hull armor is unknown, but the official documents states that sufficient frontal protection against Various Armor piercing rounds was required. Turret armor is given, based on estimates, the thickest part of the turret is around 200mm and a gun mantlet of 400mm. Due to the shape of the turret, effective thickness should be rather good.
