The Mercedes-Benz G-Klasse was an offroad vehicle manufactured by Mercedes-Benz. Several 2013 G 550 models were utilized by the staff of Jurassic World. They were silver in color, with a blue stripe down the side, and featured the park logo on the front doors.
The G 550s used by the Camp Cretaceous staff were distinct from the rest of the ones in the park. They lacked the blue stripe and had the camp's unique logo on the doors, and covered the Mercedes emblem on the grill with the Jurassic World logo as well. They also featured much heavier duty bull bars than the G 550s used elsewhere in the park. One was also seen parked outside of the Raptor Research Arena.
The campers later used another one - in regular Jurassic World livery - they'd found abandoned, but crashed it thanks to Blue.
