Development and Design

Toward the New Century of Automobiles, All FY2000 Goals Achieved

The major accomplishments in FY2000 in the development and design area include the achievement of FY2000 voluntary fuel efficiency targets through the development and introduction of new direct-injection engines and the adoption of other fuel efficiency improvement technologies, as well as the promotion of cleaner exhaust emissions. We also made major progress in the further evolution of hybrid vehicles, the expansion of hybrid vehicle series, and fuel cell vehicle development.

Development and Introduction of New Direct-injection (Gasoline and Diesel) Engines

Hiroyuki Watanabe Managing Director and Chairman of Environmental Product Design Assessment Committee Senior Managing Director since June 27, 2001

A direct-injection engine significantly improves fuel efficiency by directly injecting fuel into the cylinders, resulting in lean burn. In FY2000, Toyota developed two new types of direct-injection gasoline engines and one direct-injection diesel engine, and installed them in five vehicle series, some new and others that underwent redesign. In particular, the vehicles with direct-injection gasoline engines have, at the same time, achieved an exhaust emissions level that is 25% lower than the 2000 Exhaust Emissions Standard (qualifying them as good low-emission vehicles). s New Common-Rail Type Direct-injection Diesel Turbo Engine (Toyota D-4D)

Fuel efficiency has been significantly improved by the use of the D-4 system with a new stratified combustion concept which does not depend on air flow, further improvement in combustion efficiency, and expansion of the lean-burn area.

Hiroyuki Watanabe joined Toyota in 1967. He became a member of the board of directors in 1996 following various assignments, including that of Chief Engineer for the Crown, and later led efforts to develop electric vehicles. When he became Managing Director in June 1999, he was also appointed Chairman of the Environmental Product Design Assessment Committee. In addition, he has been overseeing Toyota's efforts to develop fuel cell systems.

First Toyota Vehicle Using Continuously Variable Transmission (CVT)

Toyota introduced CVT, which continuously shifts gear ratio, into the new Opa for the first time. Toyota CVT has a wide range of transmission gear ratios and uses a torque converter that can be locked up at low vehicle speeds. In addition, through precise transmission control, CVT enables fuel efficiency improvement and a transmission gear ratio that is optimal for engine torque. Furthermore, the Opa has achieved top level fuel efficiency in its class through integrated control of the CVT and a direct-injection gasoline engine.

Evolution and Expansion of Hybrid Systems

Following the introduction of the Prius, a compact 1.5-liter gasoline engine hybrid car, Toyota developed and introduced in June 2001 the Estima Hybrid, a new hybrid vehicle based on a 2.4-liter gasoline engine. The Estima Hybrid uses the Toyota Hybrid Sytem-CVT (THS-C), which adds a new CVT to a gasoline engine and a motor. It combines THS-C with the world's first electric 4-wheel drive system called "E-Four," which drives the rear wheels using an electric motor. As a result, the Estima Hybrid has achieved fuel efficiency that is more than twice the new 2010 fuel efficiency standard for its class. It has also achieved an exhaust emission level that is 75% lower than the 2000 Exhaust Emissions Standard in the Ministry of Land, Infrastructure and Transport's "Approval System for LowEmission Vehicles,"* qualifying as an ultra low-emission vehicle. Toyota also developed the THS-M (Toyota Hybrid System-Mild) which can be used in various vehicle types. This system improves fuel efficiency by approximately 15% and reduces total exhaust emissions. The first vehicle to use this THS-M is scheduled for introduction in autumn of 2001.

See pp. 72 - 77

Accelerating the Development of Fuel Cell Hybrid Vehicles

In March 2001, Toyota entered a new fuel cell hybrid vehicle called "FCHV-3" in the International Symposium on Fuel Cell Vehicles sponsored by the Ministry of Land, Infrastructure and Transport. FCHV-3 is based on the Kluger V vehicle body and uses hydrogen stored in a hydrogen-absorbing alloy tank. FCHV-3 achieves higher energy use efficiency, using a high-performance fuel cell stack with an improved output of 90kW, along with Toyota's unique hybrid technology that employs a secondary battery. As a result, FCHV-3 has achieved a maximum speed of more than 150km/h and a cruising range of at least 300km with a single refueling of hydrogen. Furthermore, in June 2001, Toyota developed the FCHV-4 fitted with a high-pressure hydrogen tank. Toyota obtained certification from the Ministry of Land, Infrastructure and Transport, and has begun a three-year field evaluation test. Also in June 2001, Toyota developed a large commercial transport bus, FCHV-BUS1, which uses highpressure hydrogen as fuel, jointly with Hino Motors, Ltd., and is planning to proceed with further development toward a field evaluation test.

Results of Continuous Improvement Efforts Based on Product Environmental Management System (EMS)

In FY2000, Toyota again took actions toward the goals in EMS areas 1 through 6 listed in the table to the right and made steady progress through the appropriate application of the EMS which is based on ISO 14001. This section reports the results of continuous improvement efforts in areas 1 through 4. Although some improvements in procedures and documentation expressions were recommended by an internal audit, it identified no major problems. In March 2001, the first renewal audit following certification was carried out, and an external auditing body confirmed that Toyota is appropriately applying and maintaining the EMS. Establishment of a clearer procedure for external communication was one of the items suggested for monitoring. Toyota plans to improve the EMS further by accurately incorporating these recommendations.

Improving Fuel

The Government Targets for Average Fuel Efficiency in FY2000 (old version) are:

Category 1 Category 2 Category 3 <875kg>: 18.2km/L <1,000 - 1,500kg>: 13.0km/L <1,750kg ->: 9.1km/L

FY2000 Goals Achieved

Taking into consideration the government targets (old version) in the "FY2000 goals of average fuel efficiency for gasoline-powered passenger cars by equivalent inertial weight* category," Toyota set its own voluntary goals in its Second Toyota Environmental Action Plan and worked to improve fuel efficiency within its medium to long-term plans through FY2000. As a result, Toyota achieved fuel efficiency improvement that exceeds the government targets (old version) in all categories.

Increasing the Number of Vehicles with Newly Developed Engines

Toyota developed the new AZ and NZ series gasoline engines with improved fuel efficiency achieved by making efforts from various angles, including material changes resulting in weight reduction and downsizing, combustion efficiency improvement, and intake and exhaust system optimization. Progress was also made in developing new direct-injection gasoline engines. In FY2000, Toyota achieved its fuel efficiency improvement goals by expanding the use of the newly developed engines and by installing VVT-i1 in the engines of all new models and those undergoing complete redesign.

Incorporating the Super ECT in All of the New Models

Toyota incorporated the Super ECT2, which increases the efficiency of transmission and contributes to improving fuel efficiency with its Flex lock-up system 3 and highly efficient torque converter4, into all new models and those undergoing complete redesigns. Toyota also incorporated CVT into the Opa, and electric power steering into the Corolla. The V Flex-time 4WD5, a technology for 4wheel drive vehicles, was incorporated into the Opa and Corolla.

Lighter Weight and Lower Air Resistance

Toyota worked on reducing the air resistance of its vehicles by making the floor panels flatter and using rectifying parts. As a result, the Cd (Coefficient of drag) value for the Corolla and Mark II were reduced to 0.29, and that for the Celsior, to 0.25. In terms of vehicle weight reduction, Toyota reduced the weight of the Corolla by 20kg even with a cabin space one size larger than before, using a new engine and reducing the transmission weight. How to counter the weight increases caused by the incorporation of more safety devices is an issue involving all vehicles.

Toward Achieving the New Fuel Efficiency Standards (Government Targets)

The FY2000 Government Targets (old version) became null and void when the Law concerning the Rational Use of Energy was revised in 1999, and the New 2010 GasolinePowered Vehicle Fuel Efficiency Standards were established (the target year for dieselpowered vehicles is 2005). While working on meeting the FY2000 targets, Toyota began taking actions to meet the new revised standards. Toyota is implementing measures, beginning with new models and models undergoing complete redesign, with the goal of achieving the targets ahead of schedule. In FY2000, 34% of the vehicles Toyota produced met the New 2010 Gasoline-Powered Vehicle Fuel Efficiency Standards.

Increased Introduction of Low-emission Vehicles

Toyota completed its voluntary compliance with the FY2000 Exhaust Emission Standards for gasoline vehicles, and has been actively working on the early introduction of vehicles that comply with the Ministry of Land, Infrastructure and Transport's "Approval System for LowEmission Vehicles." As a result, the number of models achieving an exhaust emission level that is 25% lower than the 2000 Exhaust Emission Standards increased to 74 (44% of the vehicles Toyota produced), and the number of models achieving an exhaust emission level that is 75% lower than the standards increased to 3 models (3% of the vehicles Toyota produced). The main technologies that helped reduce exhaust emissions include the use of (1) VVT-i, (2) a rearward exhaust layout1, (3) a stainless steel exhaust manifold2, (4) a thin-wall ceramic catalytic converter, and (5) a fuel atomizing injector3. Furthermore, the exhaust emissions from direct-injection gasoline engines were more effectively reduced using new engines and by improving the performance of the NOx storage reduction three-way catalytic converter.

Cleaner Diesel Engines

In FY1999, Toyota achieved the 1997 and 1998 Exhaust Emission Standards for diesel vehicles. The diesel vehicles launched in FY2000 ­ Hilux Surf, Land Cruiser Prado, and Corolla ­ of course meet these 1997 and 1998 Exhaust Emission Standards. In FY2000, as part of new efforts to create a new generation of diesel vehicles, Toyota developed the basic technologies for the DPNR4, a new catalytic converter system for diesel vehicles. The DPNR is a new technology that combines the NOx storage reduction three-way catalytic converter for gasoline-powered vehicles with a newly developed porous ceramic filter, and can initially reduce NOx and PM5 by 80% from the current regulation levels. However, because the DPNR requires the sulfur content in diesel fuel to be 50ppm or lower, Toyota is proceeding with a goal of commercializing it in 2003 when low-sulfur diesel fuel is scheduled to become available.

Reducing External Automobile Noise

Example of Measures to Reduce Noise Pollution

Hood silencer Dashboard silencer Apron seal

Toyota has worked on continuous improvements to attain the goal of meeting its voluntary standards on external automobile noise in all its vehicles. In FY2000, 17 passenger car series and 1 truck series (for a total of 18 vehicles series) met the standards. As a result, all of Toyota's passenger cars satisfied the voluntary standards in FY2000. Major noise reduction measures include oil pan cover and engine undercover for soundproofing, for example. Toyota also reduced combustion noise and vibration in some of the diesel vehicles by installing common-rail direct-injection engines. Intake system noise has been reduced using an intake resonator, and exhaust noise has been reduced by expanding the capacity of the submuffler, to reduce external automobile noise.

Promotion of Clean-energy Vehicles

Cooperation with GM and Exxon Mobile on Development of Fuel for Fuel Cell Vehicles

Toyota, GM, and Exxon Mobile reached an agreement on the selection of fuel for fuel cell vehicles. Although hydrogen is the most promising fuel for substantially improving vehicle efficiency and cleaning vehicle emissions, it will be some time before hydrogen can be widely used because of the necessity of establishing new infrastructures. Therefore, for short to medium-term fuel needs, the three companies decided to jointly develop Clean Hydrocarbon Fuel (CHF), which possesses characteristics similar to those of gasoline. CHF has the following characteristics: (1) The existing fuel supply infrastructure can be used, and CHF can also be used in conventional internal combustion engines (2) From extraction to use in powering a vehicle, CHF offers high energy efficiency (3) CHF burns cleanly In order to solve the various issues facing the realization of fuel cell vehicles, Toyota plans to take a global approach in cooperation with other automakers, automobile parts suppliers, and energy companies.

New Prius Launched in Europe and North America

With a new compact nickel-metal hydride battery and other improvements, the new Prius offers even better fuel efficiency, acceleration performance, and practicality than the previous model. In 2000, following its launch in Japan, the new Prius was introduced in North America in July, and Europe in September. Noting its low environmental impact and excellent performance, the Prius received positive evaluations overseas also. Sales in Europe and North America have been expanding smoothly, with about 11,600 units sold by the end of March 2001. As a result, the cumulative total sales for Japan and overseas combined exceeded 60,000 units.
