(1) Extrusion molding side sills with high strength and high rigidity
(2) Front side frame that effectively absorbs energy from a front impact
(3) Highly rigid center pillar fixed to the main frame
(4) Large area high strength rear frame that protects the fuel tank in rear collisions
(5) Highly rigid ultra-thin pillar accomplished by arc welding
(6) Double partition glass effective in improving body strength and rigidity and blocking heat and noise from the engine compartment
(7) As the outer panels could be assembled, reparability after light impacts was improved

Structure, type, measure, means, etc.:・ Rigidity was improved by a continuous floor frame that ensured a large frame section. Its ideal highly rigid design was realized by rigidity analysis of parts from the extrusion molded side sills to the subframe where the suspension was attached.
・Special aluminum welding machines were developed (arc welder and spot welder).
dot
Function, effect, etc.:・ This structure enabled the development of lightweight bodies for sports cars (white body weight: 210 kg).
dot
Points of interest, topicality:In the development stage, tests were conducted by the late Ayrton Senna at the Suzuka Circuit, who pointed out that the suspension spring constants and torsional rigidity were insufficient. Later, the Nurburgring Old Course in Germany was used as a test course to develop what became the world's most advanced vehicle body.
dot
Effect:・ High dynamic performance was obtained due to the use of lightweight aluminum in combination with high body rigidity and optimal suspension design.
