Specifications

Like any other premium cars, Nissan Leaf has sleek and stylish exteriors. The frontal part of the car is featured with LED headlamps that comprise wing mirrors for dividing the air flow and redirecting the air to reduce wind noise. The Leaf has an aerodynamic panelling which enables the car to cut the wind and reduce drag. The front bumpers are raised to regulate the aerodynamics in the frontal region. The Leaf consists of two charging ports, a regular port that takes around 7 to 8 hours to get fully charged and a quick charge port, taking half-an-hour to get charged.

The Nissan Leaf features the EM61 electric motor, which provides a remarkable mileage of 80 kmpl. The Leaf employs an 80 kW front-mounted synchronous electric motor that is powered by lithium ion battery pack having a capacity of 24 kWh. The battery pack consists of air-cooled and stacked laminated battery cells containing lithium manganate cathodes. The maximum speed the car can acquire is 144 km/h. The Leaf can be accelerated up to 100 km/hr within 12 s. The Leaf ensures non-bumpy and smooth ride with the help of 16-inch Bridgestone Ecopia tyres.

The Leaf makes use of an advanced telematics technology called Carwings for monitoring charging status, battery state and remaining charge. It employs electronic brake distribution system, anti-lock braking system, brake assist and an electro mechanical hand brake. The Leaf offers a safe drive with the help of traction control system along with vehicle dynamic control. It also employs a powerful air-conditioning system.

Summary

Besides being the top selling electric car and 2011’s World Car of the Year, the Nissan Leaf seemingly has its own pros and cons. The car road test team which tested the performance of the Nissan Leaf reports that the car is free from vibrations, which enable the user to enjoy the drive smoothly and comfortably. However, the Leaf is reported to have poor battery life as well as restarting issues. Nissan engineers identified the problem as resulting from a programming error in a sensor in the air conditioning system. Safety issues with the anti-lock braking system were also reported by several customers complaining that the brakes still remain in full force for certain time period after releasing the brake pedals. As a result, there exists a risk of rear collision occurrence.

With the rising fuel prices, the need for electric vehicles is increasing persistently. In order to meet these needs, Nissan offers an electric car that does not compromise with safety and driving range. Upon rectifying the minor issues discussed above, the Nissan Leaf can emerge as a best substitute for gasoline vehicles.
