Team Bull members at Ceradyne, together with almost three dozen employees from I3 and Oshkosh, immediately began working round-the-clock shifts. Engineers rarely left the site, with team members instead grabbing a couple of hours of sleep outside in their cars for refreshment. A six person version and a ten person version were delivered to the Aberdeen Proving Grounds for testing.

After testing the initial two prototypes, the military awarded the partnership a $18.1 million contract to produce six more Bull vehicles of the six person variant by the first quarter of 2008 for further evaluation.

It has been reported that the complete vehicle weighs around 40,000 lbs and costs about $500,000 (three times more than a Humvee). The Bull prototypes had two side hatches at the front (meeting MRAP II specs), used mainly for emergency exits. This design gave more side protection than larger traditional doors. The Bull had no gun ports, but these could be added in the final production model.
