The Lina is a pretty special, lightweight, bio-based electric city car.  And one that weighs just 683 lbs (310 kg)...yes, you read that figure right!  But it is still able to carry four people, and drive up to 50 mph (80 km/h).

The electric vehicle was developed at the Eindhoven University of Technology in the Netherlands, using bio composites (flax) for the entire chassis, body and interior.

Even if such big weight reduction would not be feasible in series production, even doubling the Lina's weight would be major improvement from a fuel economy standpoint compared to conventional cars today.  So there is perhaps something to be learned from the experiment.

"TU/ecomotive utilizes a combination of bio-based composites and bio-based plastics to create their chassis. The bio-based composite is made from flax, a plant that can be grown in the any moderate climate.

The bio-composite has a strength/weight ratio similar to glass fibre, but is manufactured in a sustainable manner. A honeycomb shaped core produced from bio-plastic, known as PLA and made entirely from sugar beets, is placed in-between two flax composite sheets to provide stiffness to the strong composite."

The Lina's power-train utilizes two DC electric motors (8 kW total) and a lithium-ion battery pack (48 V and 1.9 kWh).

The Lina was presented at the Shell Eco-marathon 2017 at the Queen Elizabeth Olympic Park in London.
