The 4x4 T17E1 was produced for the British, who dubbed it Staghound I. (Staghounds II and III were British modifications of the Staghound I and were armed with their 3" tank howitzer or the turret from the Crusader tank with the OQF 75mm Mk.V, respectively.) Standardization as the M6 was proposed in the US, but this never occurred. Each engine was provided with its own Hydramatic transmission and gear reduction case, and power was routed from these to a single two-speed transfer case. The engines could be operated singly as well as together. The hull was designed so that a frame was not required; elements including the suspension, transfer case, and steering gear were attached directly to the hull. Early T17E1s were equipped with an elevation stabilizer for the main gun.
