The Nissan Leaf was one of the first electric cars made by Nissan, and it is still one of the most popular choices for an affordable and practical electric vehicle today. The Nissan Leaf S is the base model with a number of enjoyable amenities and a commendable all-electric range of 150 miles. If you upgrade to the SV Plus, you'll get a stronger engine and battery that provide a bit more power and a longer electric range. There are three trim levels in the Nissan Leaf series, starting with the S. The second trim is the SV, which brings some additional interior upgrades and some different design features on the exterior.
