The body of the "Puma" infantry fighting vehicle is 7.35 meters long, the width of the armored vehicle is 3.7l meters, and the height of the vehicle is 3.05 meters (to the top of the commander's line of sight). Its size is medium in infantry fighting vehicles, but it is very distinctive in layout. For example, the body is very simple and smooth, with almost no protrusions; The front part of the car body is a slightly curved inclined plane, and the air intake and exhaust louvers of the engine are arranged on the front right side of the car body; Small turret size, etc. These designs not only make it invisible, but also provide a broad field of vision for the occupants.

The cockpit is located on the left side of the front of the car body and separated from the power cabin by a partition. The turret is arranged on the left side of the middle and rear part of the car body, so that the right side is used to arrange a rectangular hatch for passengers to enter and exit.

There are three periscopes in front of the driver, and the middle 1 can be replaced by a low-light or thermal imaging periscope. Because the turret is a remote-controlled unmanned turret, commanders and gunners can only do it in the car. Among them, the captain's cockpit is arranged on the right side of the middle of the car body (and then on the right side of the cockpit), and the hatch for its access is very large. Six periscopes are arranged in a semicircle, which provides the captain with a very good observation range and enables him to better understand the external situation.

The gunner's cockpit is located on the left side of the middle of the car body (the front is a solid cockpit). A periscope is arranged at the top of the cockpit and the left side of the car body, and the rectangular periscope on the left side is larger, which can provide a good side observation range. The passenger compartment can take six fully armed infantry, four of whom are located in the middle and rear position on the right side of the car body and the other two are located in the left rear side of the car body. Germans attach great importance to the humanized design of "Puma" infantry fighting vehicle. The passenger seats in the car are all suspended and equipped with seat belts, so that the infantry fighting vehicle can still ensure the safety and comfort of passengers when driving off-road at high speed.

In order to facilitate the observation of the crew, two periscopes are arranged above the center of the rear part of the car body. Unlike most infantry fighting vehicles, Puma has no shooting holes on both sides of its body, so its infantry can't fight by car. In order to make passengers fight in good condition under hot conditions, Puma is also equipped with air conditioning system.
