This isn't really a new concept because it was already displayed at the Geneva Motor Show in March, but Nissan also brought it to Los Angeles to preview "the next-generation of Nissan crossovers".
So we can say that surely we will see something similar to this passing by in our roads in a few years, probably replacing the X-Trail.
The Hi-Cross is a hybrid vehicle with a 2.0liter four-cylinder direct injection gasoline engine with an electric motor powered by a small lithium-ion battery similar to the one in the Leaf, connected to Nissan's next-generation Xtronic CVT (Continuously Variable Transmission).
