Body (NPK)

From NAGTROC

The new Nissan GT-R was engineered to offer superb high-speed stability, excellent ride comfort for a performance car and top levels of safety. Considering the extraordinary performance of the Nissan GT-R, Nissan decided that a new body structure was essential. The new Nissan GT-R uses a mix of lightweight and advanced steels, carbonfiber and die-cast aluminum for the key structural components.

Carbonfiber is used for the front end of the body structure , including the radiator support and the front of the engine bay. The advanced lightweight material gives great strength, especially in any front-end impact. Carbonfiber is also used for the rear aerodynamic diffuser undertray. Special glassfiber is used for the engine undertray, and helps give the Nissan GT-R a virtually flat bottom, further improving aerodynamics (Cd is an excellent 0.27 and that's matched to good downforce, crucial on a high-performance car).

Light and very strong diecast aluminum is used for the front suspension strut housings, and the rigid cross brace members for both front and rear suspension further to improve rigidity. The door inners are also made from diecast aluminum, giving superb side impact safety protection.

A high-precision body that guarantees supercar performance:

On the racetrack the Nissan GT-R holds firm in straight runs and tight cornering at speeds as high as 300km/h (186.4mph). Nissan designed its chassis geometry for low tire wear and its power-train geometry to minimize vibration. This and aerodynamic body sculpting helps keep interior noise to minimize at 300km/h, assuring a comfortable ride, and allows for raising and lowering windows even at 250km/h. From basic assembly to sealing, the Nissan GT-R body is built with far higher precision and lower tolerances than any previous model.

New production procedures for high-precision body fit:

For a high-precision body, the Nissan GT-R's special production procedures incorporate new ideas.
