Body Structure
Lightweight and Highly Rigid Body
1. High Strength Sheet Steel
High strength sheet steel is used in order to ensure body rigidity and realize a lightweight body.
2. Body Shell Construction
^ Gussets have been provided on the front suspension tower to ensure vertical rigidity.
^ The front cowl panel has been fastened together with the suspension tower to ensure lateral rigidity.
^ Reinforcements have been provided around the quarter window to achieve a construction that dissipates the force that is applied from the rear suspension tower, thus ensuring rigidity.
^ Reinforcements have been provided along the entire back door opening to realize a highly rigid body.
3. Sub-frame and Brace
^ V-shaped braces have been provided in the areas in which the front sub-frame is mounted to ensure their mounting rigidity.
^ A brace has been provided to join the front floor side member to the rear floor side member to ensure rigidity.
