The Call to Action“There is no future for the automotive industry

without the promotion of environmental technology. Toyota is convinced that only

companies that succeed in this area will be acceptable to society.”

Fujio ChoChairman, Toyota Motor Corporation

Page 6: Hybrid Synergy Drive

The Reality

“The new social priorities of the emerging era will call for radically new approaches to vehicles. Automakers have to address the issue of co-existence with society, particularly in relation to environmental preservation and safety…”

Hiroshi OkudaChairmanToyota Motor Corp., Japan,

2004

Environmental Commitment Toyota is a world leader in producing advanced technology

vehicles that are environmentally friendly. Toyota vehicles are consistently among the winners of

EnerGuide’s most fuel efficient vehicle in class awards. Landfill Diversion & Recycling

Reduced landfill waste by 85% at TCI headquarters Recycle 95% of packaging and parts at vehicle processing

and parts distribution centres Environmental and Community Partnerships

Toyota Earth Day ScholarshipToyota Evergreen Learning Grounds

Page 8: Hybrid Synergy Drive

A significant and growing percentage of customers indicate a willingness to buy an environmentally friendly vehicle

If, and only if, all other attributes are EQUAL

or Better

Page 9: Hybrid Synergy Drive

Technology Design Objectives Significant fuel economy improvement.

Major reduction in exhaust emissions.

No new infrastructure needs (e.g. fuelling stations).

No perceived difference by customer in vehicle performance, handling, etc.

A competitive price to encourage adoption.

What is a Hybrid Vehicle?

What is a Hybrid System?

Fusion between an internal combustion engine and electric motor—achieving different functions through different power combinations.

  Automobile hybrid systems combine two

motive power sources, such as an internal combustion engine and an electric motor.

History of the Hybrid1959-

Henney Kilowatt was the first transistor-based electric car

1990s- automotive hybrid technology

became successful when the Honda Insight & Toyota Prius became available

2000s- saw development of plug-in hybrid

electric vehicles

Types of HSD SERIES HYBRID SYSTEM

The engine drives a generator, and an electric motor uses this generated electricity to drive the wheels. This is called a series hybrid system because the power flows to the wheels in series, i.e., the engine power and the motor power are in series.

Page 17: Hybrid Synergy Drive

PARALLEL HYBRID SYSTEM

In a parallel hybrid system, both the engine and the electric motor drive the wheels, and the drive power from these two sources can be utilized according to the prevailing conditions.

Page 18: Hybrid Synergy Drive

SERIES-PARALLEL HYBRID SYSTEM

This system combines the series hybrid system with the parallel hybrid system in order to maximize the benefits of both systems.

Characteristics of Hybrid Systems

ENERGY-LOSS REDUCTIONThe system automatically stops the idling of the

engine (idling stop), thus reducing the energy thatwould normally be wasted.

ENERGY RECOVERY AND REUSEThe energy that would normally be wasted as

heat during deceleration and braking is recovered aselectrical energy, which is then used to power thestarter and the electric motor.

Page 21: Hybrid Synergy Drive

MOTOR ASSISTThe electric motor assists the engine during

acceleration. HIGH-EFFICIENCY OPERATION CONTROL

The system maximizes the vehicle’s overallefficiency by using the electric motor to run the vehicleunder operating conditions in which the engine’sefficiency is low and by generating electricity underoperating conditions in which the engine’s efficiency is high.

Hybrid Synergy Drive Benefits

CLEAN: Reduced Exhaust Emissions• Better air quality, minimizes adverse health effects

EFFICIENT: Reduced Fuel Consumption• Lower operating cost, less CO2, less oil consumption

POWERFUL: More Fun to drive• Quicker 0-100 km/h, immediate response, increased

torque

Electric cars are NOT “zero emissions” vehicles…

… because power generation creates emissions!

Hybrid Myths• Hybrids pose a threat to first responders

The brightly-colored orange wires are heavily protected and run underneath the floor in the center of the vehicle. Rescue workers can cut through any door or even a window-area without any fear of coming in contact with them.

• Hybrid vehicles need to be plugged-in Never! You never plug in the battery-pack. The engine

and regenerative braking provide the necessary electricity.• Hybrid Batteries need to be replaced

There have been no failures in service to date and there is an 8 year / 160,000 km warrantee on all hybrid components.

Page 30: Hybrid Synergy Drive

Contd…• Hybrids are small and underpowered

As explained in the last couple of slides, this is simply not the case. Hybrids out-perform their conventional counterparts and often come equipped with features not found on other models.

• Electromagnetic Fields in hybrids are harmful to human health EMFs inside and outside of Toyota hybrids are at the

same low levels as conventional gasoline vehicles. Therefore there are no additional health risks to drivers, passengers or by-standers.

• Hybrids are only about improving fuel economy In addition to improved fuel efficiency, hybrid vehicles

produce less smog forming emissions, and offer improved performance.
