Ariel is currently developing a titanium chassis which they say it's 40 percent lighter than Atom's tubular steel frame.

It will reduce the overall weight of the car by 8 percent and will find its way into a limited edition of the Atom, according to Ariel boss Simon Saunders. The frame and welding process were developed together with Caged Laser Engineering with some funds from the Technology Strategy Board's Niche Vehicle Programme. The technology could also be implemented in Ariel's upcoming motorcycle.

They are aiming at an overall weight of less than 500 kg (1,102 lbs) for the new Atom using a naturally-aspirated Honda engine and a few other lightweight components. However, Saunders said most likely the car will tip the scales at around 500 kg since it would be difficult to go down below this figure.
