All aluminum bodied Roadster features high strength, security and superior surface quality. High stressed areas are attached to the tubular steel chassis using a steel sub frame, which is providing the strongest, most durable and stable body in the market. All inner liners are in 6061 aluminum alloy including floor panels, fire wall, rear bulkhead, front wheel wells, doors, hood and trunk, processed by a CNC laser cutting system for accurate cut outs.
Behind the aluminum door panels are steel inner structures for personal protection. The chassis provides CAD engineered impact protection. In case of a rear collision the fuel cell will not advance straight toward you but through the under floor section of the car and the front section will fold down, absorbing a front impact. All brackets, hinges and panels are computer designed and CNC machined.
