Event ushers in a new era for Nissan and a new era for mobility

YOKOHAMA, (Aug. 2, 2009) – Nissan Motor Co., Ltd. today unveiled Nissan LEAF, the world’s first affordable, zero-emission car. Designed specifically for a lithium-ion battery-powered chassis, Nissan LEAF is a medium-size hatchback that comfortably seats five adults and has a range of more than 160km (100 miles) to satisfy real-world consumer requirements.

Slated for launch in late 2010 in Japan, the United States, and Europe, Nissan LEAF ushers in a new era of mobility – the zero-emission era. The car is the embodiment of Nissan’s radical, transformative vision for the future and the culmination of decades of investment and research.

"Nissan LEAF is a tremendous accomplishment – one in which all Nissan employees can take great pride," said Nissan President and CEO Carlos Ghosn. "We have been working tirelessly to make this day a reality – the unveiling of a real-world car that has zero – not simply reduced – emissions. It’s the first step in what is sure to be an exciting journey – for people all over the world, for Nissan and for the industry."

Key characteristics of the LEAF include:
1) Zero-emission power train and platform
2) Affordable pricing
3) Distinctive design
4) Real-world range autonomy – 160km (100 miles)
5) Connected Mobility: Advanced intelligent transportation (IT) system

The "LEAF" name is a significant statement about the car itself. Just as leaves purify the air in nature, so Nissan LEAF purifies mobility by taking emissions out of the driving experience. Pricing details will be announced closer to start of sales in late 2010; however, the company expects the car to be competitively priced in the range of a well-equipped C-segment vehicle. Additionally, Nissan LEAF is expected to qualify for an array of significant local, regional and national tax breaks and incentives in markets around the world. As an added benefit, because the vehicle has less mechanical complexity than a traditional gasoline-powered car, Nissan LEAF is designed to be friendly to the wallet as well as to the environment.

Nissan LEAF is powered by laminated compact lithium-ion batteries, which generate power output of over 90kW, while its electric motor delivers 80kW/280Nm. This ensures a highly responsive, fun-to-drive experience that is in keeping with what consumers have come to expect from traditional, gasoline-powered automobiles.

Unlike internal-combustion engine (ICE) equipped vehicles, Nissan LEAF’s power train has no tail pipe, and thus no emission of CO2 or other greenhouse gases. A combination of Nissan LEAF’s regenerative braking system and innovative lithium-ion battery packs enables the car to deliver a driving range of more than 160km (100 miles) on one full charge*. (*US LA4 mode)

Extensive consumer research demonstrates that this range satisfies the daily driving requirements of more than 70% of the world’s consumers who drive cars.

And, Nissan’s approach makes charging easy and convenient. Nissan LEAF can be charged up to 80% of its full capacity in just under 30 minutes with a quick charger. Charging at home through a 200V outlet is estimated to take approximately eight hours – ample time to enable an overnight refresh for consumer and car alike.

The engineers and designers behind Nissan LEAF worked to create a competitively priced real-world car that would enable Nissan to lead mobility into the zero-emission era. To ensure comfort, spaciousness and cargo capacity, Nissan LEAF employs a completely new chassis and body layout.

"Our car had to be the world’s first, medium-size, practical EV that motorists could afford and would want to use every day. And that’s what we’ve created. The styling will identify not only Nissan LEAF but also the owner as a participant in the new era of zero-emission mobility," said Masato INOUE, Product Chief Designer.

Even the smallest details can yield tremendous effect.

Nissan LEAF’s frontal styling is characterized by a sharp, upright V-shaped design featuring long, up-slanting light-emitting diode (LED) headlights that employ a blue internal reflective design that announces, "This car is special." But the headlights do more than make a statement. They are also designed to cleverly split and redirect airflow away from the door mirrors, thus reducing wind noise and drag. And, the headlights provide yet one more benefit in that they consume just 10 percent of the electricity of conventional lamps, which helps Nissan LEAF to achieve its world-class range autonomy.

Through bright trim colors inside, Nissan LEAF creates a pleasing and stylish cabin environment. An environmentally friendly "blue earth" color theme originates from the Aqua Globe body color of Nissan LEAF’s introductory model. This theme is carried into the interior through blue dashboard highlights and instrument illumination.

Nissan LEAF employs an exclusive advanced IT system. Connected to a global data center, the system can provide support, information, and entertainment for drivers 24 hours a day.

The dash-mounted monitor displays Nissan LEAF’s remaining power – or "reachable area" – in addition to showing a selection of nearby charging stations.

Another state-of-the-art feature is the ability to use mobile phones to turn on air-conditioning and set charging functions – even when Nissan LEAF is powered down. An on-board remote-controlled timer can also be pre-programmed to recharge batteries.

"The IT system is a critical advantage," says Tooru ABE, Chief Product Specialist. "We wanted this vehicle to be a partner for the driver and an enhancement for the passengers. We also wanted this vehicle to help create a zero-emission community, and these IT features will help make that possible."

Nissan LEAF is a critical first step in establishing the era of zero-emission mobility; however, Nissan recognizes that internal-combustion engine (ICE) technologies will play a vital role in global transportation for decades to come. Because of this, Nissan is implementing its zero-emission vision through a holistic approach, which provides consumers a comprehensive range of eco-friendly technologies from which to choose.

For some consumers, Nissan LEAF will be the perfect match, and the only car they will ever need. For others, Nissan LEAF will be a logical addition to the family fleet – the optimal choice for the daily commute, for example.

While zero-emission is the ultimate goal, the company is committed to ongoing innovation in eco-friendly technologies that increase efficiency and reduce emissions. As a result, Nissan offers a comprehensive suite of automotive technologies, including CVT, Idle Stop, HEV, Clean Diesel, and ongoing research and investment in FCV technology.

Zero-emission mobility programs under the banner of the Renault-Nissan Alliance include partnerships with countries such as the UK and Portugal, local governments in the Japan and the USA, and other sectors, for a total of nearly 30 partnerships worldwide.

In these partnerships major efforts focus on three areas:
1) Development of a comprehensive charging infrastructure through public and private investment,
2) Incentives and subsidies from local, regional, and national governments, and
3) Public education on the individual and societal benefits of zero-emissions mobility.

Nissan LEAF is the first in the company’s forthcoming line of EVs and is a major milestone in the realization of the Renault-Nissan Alliance’s vision for zero-emission mobility. The first of Nissan’s EVs will be manufactured at Oppama, Japan, with additional capacity planned for Smyrna, Tennessee, USA. Meanwhile, lithium-ion batteries are being produced in Zama, Japan, with additional capacity planned for the USA, the UK and Portugal, and other sites for investment are under study around the world.

Nissan Motor Co., Ltd. is a global automotive company with vehicle sales of 3.411 million in 2008. Nissan is present in all major auto markets worldwide, selling a comprehensive range of cars, pickup trucks, SUVs, and light commercial vehicles.

Nissan is committed to making a better world through its commitment to corporate social responsibility. This includes programs that focus on technological innovations that focus on people and care for the planet. Our vision for zero-emission mobility is an outgrowth of our CSR approach, which we call Blue Citizenship. Together, we are working with our Alliance partner, Renault, to make a better world through zero-emission mobility.

Aspect familiar de compactaEi bine, s-ar părea că Nissan LEAF EV este, într-adevăr, un pas foarte uriaş pentru lumea auto, la fel cum a fost, la vremea lui, Ford T, de exemplu. Chiar dacă pe piaţă există deja maşini electrice de serie (cum ar fi Tesla Roadster), acestea sunt oferite, deocamdată, la preţuri foarte mari.

Japonezii au demarat cercetarea în domeniul maşinilor electrice încă din 1992 – iar acum, la aproape 20 de ani distanţă, oferă prima maşină electrică de volum, dedicată publicului larg, care va avea un preţ accesibil (deşi cât va fi acesta, nu a fost comunicat deocamdată).


LEAF EV promite 160 km autonomieNissan LEAF EV este conceput ca un automobil de categorie compactă, având caroserie hatchback şi oferind până la 5 locuri. Dimensiunile sale sunt normale pentru berlinele de clasă compactă, utilizate preponderent ca maşini de zi cu zi: lungime 4.445 mm, lăţime 1.770 mm, înălţime 1.550 mm, în timp ce ampatamentul este foarte generos – 2.700 mm.

Maşina Nissan este capabilă de o autonomie de 160 km pentru fiecare încărcare completă a bateriilor, lucru suficient pentru a satisface nevoile a 70% din clienţi pe plan mondial. Ba, mai mult, conform cercetărilor japonezilor, 80% dintre şoferii actuali din America parcurg o medie zilnică sub 100 km, ceea ce face din Nissan LEAF EV o propunere excelentă în materie de maşină pentru navetă.

140 km/h viteza maximaNissan LEAF EV este alimentată de la un tip complet nou de baterii litiu-ion, capabile să genereze 90 kW (120 CP) şi alimentează motorul electric de sub capota faţă, care dezvoltă 80 kW (107 CP) şi un cuplu maxim de 280 Nm. Adică mai bine decât cel mai economic Volkswagen Golf 1,6 TDI (105 CP şi 250 Nm). Viteza maximă atinge doar 140 km/h, însă vorbim de o valoare mai mult decât suficientă pe orice autostradă.

Bateriile utilizate de Nissan LEAF EV sunt situate în planşeul maşinii, fiind realizate după o tehnologie complet nouă. Ele constau dintr-un ansamblu de 48 de module litiu-ion, fiecare modul de dimensiunea unui laptop şi format din patru celule. O încărcare completă, de la o sursă de 200 V, durează 8 ore, însă marele avantaj al acestor baterii este că se pot încărca la 80% din capacitate în doar 30 de minute, o performanţă excelentă pentru maşinile electrice.

Interior foarte modernSingura problemă, deocamdată, ţine de infrastructura pentru încărcare: este nevoie de un încărcător special, tri-fazic, estimat la 45.000 USD! Oficialii japonezi colaborează deja cu multe state din USA şi Europa pentru crearea acestei infrastructuri, care deja face parte din programele lor ecologice.

Deşi bateriile însumează o masă totală de 200 kg, inginerii Nissan declară că motorul electric este mult mai uşor decât un motor cu ardere internă, iar lipsa unei transmisii convenţionale va contribui la un centru de gravitate foarte jos, ceea ce va însemna că Nissan LEAF EV promite o manevrabilitate şi stabilitate foarte bune.

Economie de 50 USD pe lunaRaportat la condiţiile din Japonia, oficialii Nissan declară că Nissan LEAF EV va contribui la o economie în buzunarul proprietarului de aproape 5.000 yen pe lună (sau circa 50 USD). Este adevărat, nu vorbim de o economie foarte mare, care diferă de la ţară la ţară şi care, cel mai probabil, nu va justifica la început investiţiile enorme în infrastructură.

Costul maşinii de serie, prevăzută a fi lansată pe pieţele din Japonia, SUA şi Europa începând cu 2010, nu a fost comunicat încă, dar ştim că Nissan va oferi o garanţie de 3 ani pentru maşină şi de 5 ani pentru sistemul de propulsie. Pe de altă parte, înlocuirea pachetului de baterii este estimată la 10.000 USD – mult mai scump decât întreţinerea curentă a unei maşini convenţionale de aceeaşi categorie.

Încă un lucru inedit: primele modele de serie vor fi echipate standard cu un sistem de navigaţie, cu acces direct la un sistem global GPS, prin intermediul căruia şoferul va putea găsi cele mai apropiate staţii de încărcare. Acest lucru va fi disponibil şi prin intermediul telefonului mobil, iar maşina va putea fi programată, de exemplu, să maximizeze încărcarea bateriilor la miezul nopţii, când furnizarea de energie electrică este mai ieftină.
