The concept behind this design is to create a more modern counterpart to classic minimalist sports cars like the Lotus Elan, keeping the precise driving experience but with the benefit of more modern crash safety and reliable mechanicals. The miata has done a fantastic job but I want something less compromised feels more alive.
To provide a tight feel the chassis needs to be very stiff. I am using a spaceframe design, which uses triangulation to make a stiff, light structure out of small tubing. It is a very efficient way to transmit loads between suspension hardpoints. Unlike many existing space frames, I am using substantial side sills that provide stiffness and strength to the what is generally the weakest part of an open car. The wide sills also protect the occupants from side impacts by preventing intrusion and absorbing crash energy. My spaceframe also surrounds the engine bay, allowing a higher mounting point for the spring units which results in a more linear spring rate. It also provides a more direct load path for frontal impact energy to the windshield frame and roll cage. I will have structures front and rear to absorb crash energy to protect the occupants.
