The Nissan Leaf electric car and Chevy Volt plug-in hybrid went on sale within days of each other back in December 2010.
Now, we're expecting second-generation versions of both cars for 2016--and each will have significant upgrades.
The most significant upgrade to the Nissan Leaf will be a choice of battery-pack sizes, meaning more range than the car's current 84 miles.
Nissan product chief Andy Palmer told Green Car Reports that he could envision two or even three different pack sizes, giving buyers the option of paying more to get greater range--possibly 120 miles, maybe closer to 150 miles.
That could give the top-level Leaf about three-quarters the range of a low-end Tesla Model S. If its price were around $35,000--just half the cost of that Tesla--we think a lot of buyers would consider Leafs who now say 84 miles is just too little.
