Tokyo International Motor Show 2003 Overview: Toyota-Lexus

.
Fine-N

A fuel cell hybrid vehicle meant to shape the future of motoring, the Fine-N features radical styling in a novel package and 4WD using four in-wheel motors to achieve new dimensions in driving performance together with epoch-making environmental performance.

Long cabin with futuristic styling: Fuel cell hybrid technology permits great freedom in power train layout, allowing the wheels to be positioned nearly at the four corners of the vehicle. Together with a long wheelbase, this results in a long cabin that offers a new experience in driving comfort and convenience, including a control interface that guides the driver with sight and sound.

New dimensions in driving performance: This new package fits heavy components, such as the fuel cell stack, power control unit and battery, in low, central positions to lower the center of gravity and minimize yaw moment of inertia.

Four-wheel in-wheel motor system with by-wire control: Mounted on the inner side of each wheel is a compact, lightweight, high-efficiency electric motor. Each of the four individual motors is rated at 25kW peak power and 110n-m peak torque. Each motor's drive power and braking is individually and continuously controlled by drive-by-wire technology to provide optimized wheel-by-wheel acceleration/deceleration and steering control according to steering angle, vehicle and road conditions and other parameters.

Toyota FC Stack fuel-cell technology: The four in-wheel motors are driven by electric power supplied by the Toyota FC Stack and a lithium-ion battery. Raised fuel-cell efficiency and increased hydrogen tank pressure give the Fine-N a cruising distance of 500km.

Biometric security and personalization system: Using biometric face-recognition technology, this system authenticates drivers to provide enhanced security and then personalizes seat position, audio system, climate control and other settings automatically.

CS&S

With its midship-mounted next-generation Toyota Hybrid System THS II* based on the Hybrid Synergy Drive concept and an E-Four (electric 4-wheel drive) system, the CS&S is designed to provide outstanding environmental performance and driving exhilaration.

Outstanding driving performance: The next-generation hybrid system combines a 1.5-liter gasoline engine and 50kW high-output motor for powerful acceleration. Four-wheel control provided by the E-Four system and the midship positioning of the hybrid power plant further enhance handling and road-holding performance.

.
Alluring styling: The simple and geometric design's two-seater canopy lines flow naturally into wheel arches that anticipate the 4WD system's powerful performance. Contrasting curves and sharp angles complement short, wide and low-slung proportions.

Simple & sporty interior: Linked to the exterior design, a horseshoe motif defines individual spaces for driver and passenger, emphasizing a sporty drive feel.

Sliding-canopy 2+2 seater: Rear seats can be made available by sliding back the canopy. The front seat-backs can be pushed all the way forward to secure the car.

Space Touch control interface: The driver "touches" a spherical holographic interface for natural, effortless control.

SU-HV1

The SU-HV1 features an SUV-optimized Hybrid Synergy Drive and E-Four to deliver a new kind of powerful SUV performance together with compact-car-class fuel economy.

Powerful new SUV-optimized hybrid system: The hybrid system power unit comprises a 3.3-liter V6 gasoline engine together with a 120kW motor. By raising the electrical system voltage and using a faster spinning motor and generator, Toyota has achieved higher output and torque for optimum pairing with the V6 engine.

.
To configure the E-Four system, Toyota added a 50kW rear motor, which also achieves higher output and torque as a benefit of the more powerful electrical system. The result is awesome power.

Environmental performance of a compact car: This application of Hybrid Synergy Drive gives the Toyota Hybrid SUV V8-level performance with fuel efficiency and emissions at compact car levels, twice as good as those of an SUV of equal displacement.

Advanced Vehicle Dynamics Management (VDM): The VDM concept for next-generation vehicle movement control coordinates the hybrid system, E-Four and Electronically Controlled Brake System (ECB) for dramatically improved handling and road-holding stability.

.
PM

Designed to "meet, link and hang out," the PM is a "wearable" single-person vehicle that targets driver-vehicle unity and offers advanced vehicle-to-vehicle communication.

Driver-vehicle unity with ergonomic focus: Cabin and seat shape are designed to fit almost like a glove, while integrating the driver's intention with the car's capabilities.

Variable "lifelike" posture: The cabin and wheel-suspension structure are separated, allowing the PM to vary its posture according to speed and to facilitate entry and exit. Antennae-like headlamps contribute to the image of an exotic life form.
.

Space input display: A floating virtual display senses driver finger position and shows vehicle data, locations of other PMs and other information.

Vehicle-to-vehicle communication: PMs can share information as they travel, follow a leader in platoon formation and rendezvous automatically.

A further evolution of the PM concept called the "i-unit" will be featured at the Toyota Group Pavilion at EXPO 2005 AICHI, to be held in Aichi Prefecture, Japan, beginning March 25, 2005.

Lexus LF-S, LF-X Concepts

Toyota established Lexus in North America in 1989 with the brand concept of pursuing perfection in product as well as in sales and service. Lexus then expanded into Europe and other regions, earning high acclaim as a premium brand that delivers high satisfaction in response to user values.

Looking ahead to the August 2005 launch of the Lexus brand in Japan together with a nationwide dealership network, Toyota's two Lexus concept cars to be exhibited at this year's Tokyo Motor Show are realizations of a quest for the essence of luxury in every detail. They seek to provide a peak experience that satisfies the heart with exhilaration and comfort at every moment, while understanding and anticipating each individual user’s constantly changing needs. These two cars are the LF-S, a next-generation sedan that expresses the Lexus brand’s new conception of luxury, and the LF-X, an SUV-sports sedan crossover.
