4. Electric Vehicle (EV)
As discussed by the IPCC (Intergovernmental Panel on Climate Change), the level of CO2 emissions will need to be reduced below 550ppm by 2100, in order to minimize global warming. In order to meet the IPCC's goal, Nissan estimates that they will need to reduce CO2 emissions in new vehicles by 70% from the levels emitted in 2000 by the year 2050.
In the short term, the most effective method to reduce CO2 emissions is to improve the fuel efficiency for existing internal-combustion engines (including diesel) or to introduce hybrid vehicles. However, this will only reduce CO2 emissions by 30 to 50%, even if the potential of future technologies is taken into consideration. In order to achieve this 70% reduction, zero emission vehicles are necessary for the medium- and long-term.
Announced in May 2008, the new midterm business plan, NISSAN GT 2012, set "Zero-emission vehicle leadership" as a target. Under this commitment, Nissan will introduce all-electric vehicles (EV) with zero CO2 emissions in FY2010. The EV will be mass-marketed in FY2012.
Lithium-ion batteries that exhibit reduced size but with increased capacity and power are essential to the EV. Nissan has been developing this technology since 1992. In April 2007, Nissan established a joint-venture company, Automotive Energy Supply Corporation (AESC), with NEC and NEC TOKIN. AESC will commence the mass-production of lithium-ion batteries in 2009. Nissan has been developing this battery technology ahead of its competitors. The company aims to maximize the battery's performance and safety with high power and energy density. The battery utilizes a laminated structure, which has superior cooling efficiency and manganese type electrode material with stable crystal structures. Its high stability and durability, even under the harshest conditions, have been confirmed.
Nissan is developing the EV while targeting a maximum speed of over 140km/h and a driving range of 160km. As the driving range for the typical driver is less than 100km, a range of 160km should satisfy most consumer needs. In order to counter the driving range issue, Nissan continues to develop further their advanced battery and accelerate the establishment of a network of charging stations through a variety of partnerships including many governments, some of which have already been announced.
The EV's appeal is not only its zero emissions but also its powerful and smooth acceleration due to the electric motor. As the advanced laminated compact lithium-ion batteries are installed under the floor, the EV also exhibits stable cornering. Compared to standard gasoline engines, the EV's attractiveness is also featured in its quietness. One participant who test drove the EV said, "Before I drove the EV, I imagined a kart. But Nissan's EV is well built with good driving performance that is ordinary not evident with the standard gasoline engine. I'm looking forward to the start of EV sales".
Depending on the country and various assumptions, the cost of the electricity for charging the EV is cheaper than the fuel required for a standard gasoline engine. The advantage is even wider when the EV is charged by nighttime electricity.
While the test vehicle used at the briefing was based on an existing model, the EV Nissan will sell in 2010 will feature an original design. The EV can be designed drastically different than traditional vehicles due to its technology, as exhibited by the PIVO2 concept car, which is equipped with In-wheel Motors.

5. Summary of environmental technologies
Prior to commercialization, the technologies mentioned have not been frequently seen. However, Nissan is implementing comprehensive environmental technologies, which incorporates driver behaviors while using clean energies.
Please continue to expect the best from Nissan and its future vehicles.
