Here they are!




Electric Vehicle (EV)

Powered by advanced lithium-ion batteries, the EV prototype is part of Nissan’s substantial research and development program on zero emission vehicles. This latest generation vehicle features a front-wheel drive layout and uses a newly developed 80kW motor and inverter. The advanced laminated compact lithium-ion batteries are installed under the floor, without sacrificing either cabin or cargo space.

The production vehicle to be introduced in 2010 will have a unique bodystyle and is not based on any existing Nissan model.


Hybrid Electric Vehicle (HEV)

The Nissan original HEV delivers two breakthrough technologies – a high-performance rear-wheel drive hybrid system and parallel-powertrain hybrid system. The hybrid employs Nissan’s own originally developed hybrid technology and its first rear-wheel drive hybrid powertrain.

The parallel-powertrain system comprises an energy-optimizing system with two clutches, where one motor is directly connected to an engine and transmission via two separate clutches. Under changing driving conditions, the motor switches between the two clutches to optimize and conserve energy utilization as well as improve fuel-efficiency.

The parallel-powertrain hybrid system eliminates the need for conventional torque converters, contributing to higher responsiveness and linear acceleration for improved driving feel.
The dynamic characteristics of the clutches are as follows:
Idle-stop: The battery is used to power the motor to save on fuel.
Regular driving: The engine is used to power the motor as well as regenerate the battery.

Acceleration: Both the engine and battery (power assist) is used to power the motor to achieve smooth acceleration.
Deceleration: Energy from braking is conserved and re-routed back to regenerate the battery.


Lithium-ion Battery

The advanced lithium-ion batteries used in both prototypes are sourced from the Nissan-NEC joint-venture, AESC (Automotive Energy Supply Corporation). These advanced batteries offer superior performance, reliability, safety, versatility and cost competitiveness, compared to the conventional nickel metal-hydride batteries. Its compact laminated configuration delivers twice the electric power compared to conventional nickel-metal hydride batteries with a cylindrical configuration. The compact batteries also allow for improved vehicle packaging and a wide range of applications.

Nissan has long experience in electric-powered vehicle development, commencing from the first EV "Tama Electric Vehicle" back in 1947. The company introduced the world’s first application of lithium-ion batteries to the Prarie Joy EV in 1996, followed by the ultra-compact electric vehicle, Hypermini, released in 2000. Nissan also introduced its first original hybrid vehicle Tino Hybrid back in 1999 in Japan. In 2006, the Altima Hybrid was introduced in North America using licensed technology.

Under the Nissan Green Program 2010 environmental plan, the company aims to develop new technologies, products and services that can lead to real-world reductions in vehicle CO2 emissions, cleaner emissions, and recycling of resources. Nissan continues to invest substantially in a wide range of technologies including CVT (Continuously Variable Transmission), VVEL (Variable Valve Event and Lift), clean diesels, biofuels and fuel cell vehicles.

So is this EV a prototype or just a concept? I am getting more and more interested in what they have in store for us at Detroit, 2009. This vehicle is tentatively scheduled to launch at the same time as the Volt, which I'd consider a competitor. Thoughts?

Looks like they license their styling from Toyota too! So much for the "EVs need to be aerodynamic" theory.:rolleyes:

According to today’s Yomiuri daily the EV’s estimated range is 100 miles per charge.

As for the hybrid the press release is vague about the drive train design. It did say the car can run on ICE only, electric motor only and on both. The fact that it does not have a torque converter between ICE and transmission and comes with two clutches means start-up is done by electric motor, and as the car gains speed, the clutch between ICE and transmission engages starting ICE (or maybe it is already running), then the clutch between electric motor and transmission (?) disengages and motor is turned off for ICE only cruising. When accelerating the electric motor comes on to assist ICE. The motor has dual functions: propulsion and generation/regeneration.

I remember the Tama EVs … They were used as taxis to shuttle train commuters from stations in the suburbs to/from their homes located 2 to 5 miles away. I remember the buzzing noise of chargers at the station nearby. Tama was an independent automaker at that time. It was bought out by the Prince Automobile Company (known for the Skyline model), which in turn was absorbed into the Nissan Motors later.
