Lotus Esira Concept

Just so it's clear, this car is made of fabric. Its design formula follows the idea of a complex frame blanketed by material. It was designed by Jack Lamburn, a former Northumbria University student.

The concept showcases very futuristic lines and flow while maintaining ultra light-weight assertive sports orientation.

The concept is designed for 2025 so its focus is to be both agile and environmentally friendly. It does this by using two asynchronous electric motors powered by a hydrogen fuel cell.

It's rear-wheel drive, so it's still a sports car, but the motors have been placed very low down near the wheels, to lower the overall centre of gravity.

The wheels look strange, because they are. The body work has been moulded, aerodynamically, to accommodate the wheels. This is said to reduce drag so it can be fast and efficient.

So back to that fabric bodywork. Underneath, there's a tubular frame and carbon fibre platform. Elements of the interior are also made from a honeycomb composite, much like an F1 car, which is very strong and very light.

The skin of the body is made from two layers of material, or fabric. The first layer is something called 'd30'. This material is said to be 'high impact absorbing', so it will protect the occupants... somewhat.

The second layer is the most interesting element of all though. It's made of something called metal rubber. This means it can stretch, like rubber, but it also means it has metallic properties. And not those you may initially think of.

Because the material can conduct electricity, like metal, the surfaces can be adjusted via the on-board computer. So it has an adjustable body. This further enhances its ability to be agile and versatile in the corners.

It's all just a concept though, of course. And a very interesting one at that.
