Ariel, the gang behind the Atom open wheel sports car, is aiming to make the vehicle even lighter.
How? By building the chassis out of titanium – a costly process that could reduce the car’s overall weight by almost eight percent. Titanium has the highest strength-to-weight ratio of any metal, but it’s agonizingly difficult to work with. If it’s exposed to oxygen while welding, the metal combusts before it melts — which means the fabrication process requires a special argon-filled welding chamber.
Because of that, Arial isn’t sure if the chassis will be sold as a limited edition or as an option.
One way or another, brand boss Simon Saunders tells AutoCar that the company’s goal is probably to build an Atom that weighs 500 kilograms (1,102 lbs).
