Nissan unveiled the shape of a new Nissan Leaf which is expected to be shown to the public in less than a month. Next-gen Leaf silhouette is pictured on a recent teaser image. The press-release also states that Nissan engineers and designers worked a lot to improve the car’s aerodynamics – increasing the stability on high speed, improving the crosswind resistance and reducing the drag, thus increasing the range at the same battery pack capacity.
