2. The T27 Armored Tank
T27 was an enormous eight-wheeled armored tank developed in 1944 by the Studebaker Corporation for the US Army. Its production did not, however, go past the prototype. It was canceled in the favor of a competing design by Chevrolet.
Intended to replace the M8 Greyhound, the T27 Armored Car was armed with two .30 caliber machine guns and a 37 mm cannon and wad also powered by a Cadillac gasoline eight-cylinder engine. It could accommodate a crew of four.
After its completion in late 1943, this prototype armored car developed for the US Army was taken to the Aberdeen Proving Grounds in 1944 for testing against the T28 Armored Car. T28 was found out to be more mobile than the T27. However, they both proved their superiority to the mobility of the M8.
