At the Nissan future event in Oslo Nissan confirmed, that it will unveil the Nismo version of new Leaf at the Tokio car show.
There will be some unique design features on the Leaf Nismo, like red trim pieces and black bonnet and roof, but more or less it will look quite similar to regular version. Nissan will probably base sporty version of Leaf on the "e-Plus" version with higher battery capacity and more powerful engine.
But we all will know more by the end of October.
