Nissan will unveil a completely redesigned version of its all-electric Leaf in a heavily promoted event later tonight.

Why it matters: The overhaul arrives at a time when analysts are upping estimates of the EV market's growth in coming years and decades, and countries including France and the U.K. are rolling out more aggressive clean transportation policies.

The automaker faces big challenges, even though the Leaf is the leader in cumulative worldwide EV sales since its 2010 debut, with over 280,000 sold. These days Nissan has lost ground to Tesla and other rivals who offer models with much more range than the current generation Leaf's roughly 100-miles-per-charge capacity.

Nissan has already revealed that the new version will feature tech including its single-pedal operation mode called "e-Pedal," and its "ProPILOT" assisted-driving system.
