The original pilot models were submitted and named accordingly. As as result, Ford and Willys were asked to product their own pilot models for testing, the results of which would determine the contract. While the 'Blitz Buggy' did satisfy these requirements, Bantam was not able to match its production and budget needed by the War Department. (115 N m) of torque, along with an empty weight of no more than 1,300 lbs (590 kg). Nicknamed the “Blitz Buggy”, this vehicle concept which was the first bid accepted by the Army, as it satisfied the Army’s Ordnance Technical Committee specifications that the vehicle have: four-wheel drive, a crew of three on a wheelbase of no more than 75 inches and tracks no more than 47 inches, a fold-down windshield, a 660 lb payload, and an engine capable of 85 ft lb. Prior to the production of the MB/GPW, other attempts were made to satisfy the Army’s need for a light utility vehicle including the first prototype presented by the American Bantam Car Company.

Soon to become the ubiquitous, world-famous jeep, the Willys MB and Ford GPW models were very effective on the ground, with many standardized features such as 6.00x16 tires, 60 honest horsepower at 4,000 rpm, a gasoline can bracket on the left rear, provision for trailer lights, spark interference suppression, a blackout light system, twin top bows and sealed spring shackles. During WWII, the Ford GPW and Willys MB played a powerful role in increasing the efficiency and mobility of the US Army, adopting distinctive features, some recognizable even today, that would continue to influence the design and silhouette of the modern “sport utility vehicle”.
