Sunny's frame is constructed with lightweight materials, yet is extremely solid. Plus, Torsional rigidity is 30% greater than that of conventional models.

The Nissan Sunny is built with a highly stable, yet lightweight metal structure. The unibody construction uses weld bonds and sub frames to connect vehicle elements together.

The Sunny has also been designed to meet European offset collision standards and U.S. side collision standards.

Air flows all around a moving vehicle, including beneath it. So, with Sunny, even the undercarriage is aerodynamically calibrated to control airflow.

Robotic precision is utilized in the construction of the Sunny chassis. This manufacturing technique assures strength and quality every time.

Reinforced areas of the frame are made with solid steel, making the hull durable and protective.
