For 2015, the Nissan Leaf adds a more aggressive regenerative braking mode to the base model, and there may be a voice-to-text messaging and navigation voice command to SV and SL models. The SV also now gets 17-inch wheel, and I like it very much. The Leaf can travel 84 miles on a full battery charge. That may not sound like a lot, and for long-range suburban commuters without access to a charging station, it may not be. But it's enough range for most in- and around-town driving and short commutes, and still ranks as one of the highest in its class. I use lot of cars but really like this Nissan.
