At a U.S. launch event for the Leaf electric car on Friday, a Nissan product planner Mark Perry told Paul Eisenstein of the Detroit Bureau that the Japanese automaker was looking at a similar idea. Lithium ion batteries are likely to remain expensive for the foreseeable future, so in a bid to make EVs more affordable, they could be offered with different battery capacities. Tesla is planning to offer three sizes for the Model S with ranges from 160 to 300 miles. The Leaf doesn’t have room for a pack larger than the initial 100-mile range, but future models may be designed to accommodate larger packs while the base versions would come with a smaller unit.
