Electric cars need steel bodies

The next generation of electric cars will need specifically designed steel bodies to exploit their green potential, according to the world’s biggest steel makers.

A new research project, the Future Steel Vehicle (FSV), is testing redesigned structural parts in an electric car’s bodywork, including the sills, front crash structure, roof and battery carrier, to cut weight and save energy.

Engineers are also weighing up a variety of steels to balance their strength in an EV body against the energy used in its manufacture. This will reduce the whole-life energy costs of an EV.

Previous steel industry projects have advanced the design of lightweight steel car bodies, doors and suspensions.
