The first purely battery-electric car to be put into mass production in the U.S., the Nissan Leaf was introduced as a 2011 model with a slow rollout across the country. By the end of 2011, the Nissan Leaf will be available for sale in every state. Though it has a starting price of $32,780, the car qualifies for a federal tax credit that can lower the price effectively to $25,280. Tax incentives in many states can reduce the car price further.

While the Leaf's range is approximately 100 miles per electrical charge, Nissan views this alternative-fuel car as a fuel-efficient auto suitable for most drivers who typically use the Leaf as a commuter car, recharging it when they return home for the day.

Standard features include push-button start and stop, climate control, remote keyless entry, power windows and door locks, cruise control, a 60/40 split-folding rear seats, a navigation system and six airbags as well as stability and traction control. A battery pack powers an electric motor that produces 107 horsepower and an impressive 207 foot-pounds of torque. Recharging a fully depleted battery takes about seven hours at a 220-volt, home-charging dock.
