Lamborghini lifts the lid on a supercapacitor-enhanced Sian Roadster

The outrageously-styled Sian is Lamborghini's most powerful supercar in history, aided by a supercapacitor hybrid powertrain. Now, it's back as a roofless Roadster that's somehow even sexier – but don't get your hopes up, it's sold out.

These forest-like rows of carbon nanotubes were created on an elastomer substrate that was pre-stretched in one direction and then allowed to contract. This process creates stretchable supercapacitors that hold more charge in less space and remain functional even when stretched to eight times their original size
