Some basic physics : more electrons = more protons and neutrons = more mass.
Skepticism Persists as Nissan’s Ghosn Leads Charge Into EV Age: "According to Ghosn, the Leaf's 100-mile (160-km) range covers 90% of the daily driving needs in Japan and most other major markets. The problem is that other 10%.
“Buyers would basically be paying the price of a Lexus for a second car,” one Nissan official admits.
While the basic story line is right, Ghosn has omitted a few details that could make the road ahead a little bumpier – namely, that the Leaf’s 100-mile range is achieved without engaging the car’s air-conditioner and heater, which knocks off 30%. Also, the life of the battery for automotive use is estimated at only four to five years."
