Taking Lotus’ overriding design philosophy of featherweight construction to the next level, designer Jack Lamburn has come up with a car concept that features impact-absorbing fabric body to reduce its weight. Dubbed the “Esira,” the Lotus concept features the bodywork finished in two advanced and reactive materials, the d3o and the metal rubber. The d3o is a non-Newtonian material used in protective motorcycle gear to bulletproof vests; while on the other hand, the metal rubber stretches and molds like rubber. Therefore, the bodywork reacts to the movement of the suspension system and conducts electricity to adjust its shape using the onboard computer.
As the car moves, the bodywork changes its shape to maintain the smooth airflow as well. It also includes a tubular frame to add support to the bodywork. Presenting a bit more traditional interior made in carbon fiber, the Lotus runs on a hydrogen fuel cell powertrain with two asynchronous electric motors transmitting power to the rear wheels. The Esira replaces the handle with a lever, located under the seats, to open the doors, which gives you the feel of riding in a fighter aircraft. While the lower center of gravity helps in increasing the agility of the car.
