Grizzlies are several meters longer than the Mako; however, when stripped of its antenna and turret, they are roughly the same height. With these optional features, the Grizzlies are taller than a Mako. Six people, including the driver, can fit inside the vehicle. The Grizzlies are compartmentalized into a driver/antenna/engine compartment and a passenger/turret compartment. There is a crew hatch in the driver/engine compartment. The vehicle's power cells are located in the front of this compartment. These cells power the systems aboard the vehicle and provide propulsion power to the wheels located on either side of the passenger/turret compartment. All six wheels of the vehicle are protected by wheel covers.
