The 2011 Nissan Leaf is the world’s first mass-market all-electric automobile, to be built in the hundreds of thousands globally/annually by Nissan beginning this winter. And may I say, thank God and Carlos Ghosn, chief executive of Nissan. Not so much a game changer as a game starter, the Leaf is a five-seat, five-door passenger EV sedan sold from California to Maine, with a nice, round 100-mile estimated range; 0-60 mph acceleration of around 10 seconds; and a top speed of 90 mph. The U.S. price is $32,780 (not counting the $7,500 federal tax credit for EVs) and includes a host of value-added, segment-competitive features, such as Bluetooth, navigation, 16-inch alloy wheels. Such a car would have been science fiction five years ago.
