Not so radical as the philosophy of the Transformers, but the specialists have decided to use the Siemens VDO invention in a new project that will increase the security of the cars in case of lateral collision, thaks to a system that transform the form of the doors into a franstion of seconds before the impact.

The scientists are using a special metal called "shape memory allaoy to create the testing vehicle. When a small current passes through the alloy, it swells into a pre-programmed shape. It can be put in small pistons and make them move quickly to flex panels outwards and reinforce the frame at crucial points."

It is a chance that with this techniques to see in the future aerodynamic designs and lighter chassis, things that will allow to save fuel.
