Mazda/Mitsubishi Motors/Fuji Heavy Industries: Developing Hybrid Electric Vehicles (HEV), Electric Vehicles (EV) and Biofuel VehiclesThe three automakers' mid-term environmental plans targeted for 2010

Oct. 7, 2006 No.516


  Around 2000, many of the Japanese automakers announced their mid-term plans to achieve the environmental goals by 2005. The initiative is now being followed by new mid-term environmental plans targeted for around 2010.

  Toyota announced its new plan in May 2005, followed by Hino in December of the same year and Daihatsu in January 2006. Mitsubishi Motors came up with its plan in July 2006, and Mazda and Fuji Heavy Industries in August 2006. Honda also made public its voluntary target for 2010 to reduce CO2 emissions in May 2006.

  Following is the outline of their product development plans in the automotive sector announced by Mazda, Mitsubishi Motors and Fuji Heavy Industries in their mid-term environmental plans. One of the features of the product plans is that a new power system is targeted for commercialization: Mazda plans to commercialize hydrogen-fueled engine vehicles (bi-fuel vehicles which can run on petrol as well), hybrid vehicles, and alternative-fuel vehicles; Mitsubishi Motors electric vehicles, biofuel vehicles, and the next generation clean diesel engine vehicles; Fuji Heavy Industries hybrid vehicles and electric vehicles.

(Note) For Toyota's and Honda's mid-term environmental plans, please refer to our Marklines Report No.499 (August 2006 issue) "Toyota's and Honda's mid-term environmental plans: expanding the hybrid vehicle (HEV) lineup and renewing a series of engines

■Mazda: introducing hydrogen-fueled rotary engine vehicles, hybrid vehicles (HEV) and alternative-fuel vehicles

  Mazda announced its new mid-term environmental plan "Mazda Green Plan 2010" in August 2006, in which the automaker set out its goals for 2010 for cleaner emissions, greater efforts at recycling automobiles and preventing global warming. 94% of the Mazda vehicles which were produced for the Japanese market during April-June 2006 have the SU-LEV status (a 75% reduction of emissions from the 2005 emissions standards). All of the automaker's vehicles sold in Japan in fiscal 2005 have cleared the 2010 fuel efficiency standards except those in the 1.5 ton weight class. Every version of the Demio, the automaker's top seller, which received minor modifications in April 2005, has been awarded the SU-LEV status with its fuel consumption 5-20% lower than the 2010 standard.

  Mazda has added diesel versions (with a common rail direct injection turbo diesel engine plus DPF) meeting EuroIV emissions standards to more models which include the Mazda 3 (Axela), Mazda 5 (Premacy) and Mazda 6 (Atenza).

  In its plan for 2010, the automaker aims to improve fuel efficiency while reducing emissions and to develop hydrogen-fueled rotary engine vehicles, hybrid vehicles, and vehicles which can cope with synthetic fuels such as biomass and GTL: the automaker also disclosed the development of a reliable idling stop and start system for petrol vehicles.

  The automaker's hydrogen fuel rotary engine vehicles (bi-fuel vehicles which can run on petrol as well) began to be leased in Japan in March 2006. Its hybrid vehicles which are jointly developed with Ford began going through the verification test in the USA in February 2006. And vehicles which run on diesel oil with a 5% ethanol mixture, part of the automaker's biomass program, are on sale in Europe. In addition, the concept of combining a hydrogen fuel rotary engine with a hybrid system (HEV) was disclosed at the 2005 Tokyo Motor Show.

Note: Another example of body weight reduction is the new Roadster launched in August 2005. The target weight was set at 1,128kg, which the automaker was able to get down to 1,090kg (5 speed MT) through the use of aluminum bonnet and trunk lid. Although the weight of the white body is 1.6kg lighter at 247.5kg, both bending and torsional stiffness has increased by 22% and 47%, respectively, through the use of ultra high tensile steel as well as high tensile steel.

■Mazda: developing smart idling stop system

  The automaker is developing a smart idling stop system which is based on idling stop mechanism using direct injection system, as opposed to an ordinary idling stop mechanism in which the engine is restarted by motor.
  In the system under development, fuel is directly injected into cylinders of engine which has stopped running. It allows explosions to take place, with the energy pushed down the pistons, thereby restarting the engine. This system is more fuel efficient because the engine does not run when the vehicle is stationary, and is more quiet because it does not use the motor, and allows the engine to restart more quickly. Because it is of simple structure, it stays highly reliable despite repeated restarts.
  Technologically the system requires precise control of the engine, which will enable the pistons to stop at the designated position when the engine stops.

■Mazda: the automaker began leasing the RX-8 Hydrogen RE, a bi-fuel car which can run on both hydrogen and petrol

  The automaker began leasing the RX-8 Hydrogen RE with hydrogen-fueled rotary engine in March 2006. When it is running on hydrogen, the vehicle emits no CO2 and its NOx emissions are extremely low.
  The vehicle is dual fuel. A switch located close to the driver allows the vehicle to run either on hydrogen or petrol. Existing engine components and production facilities can be used to produce the vehicle, which will allow it to be commercialized at a low cost with high reliability.
  The vehicle was shown at the ONS 2006, an energy exhibition held in Norway in August 2006, and demonstrated its capability outside Japan for the first time.

■The RX-8 Hydrogen RE's performance

  The fuels used are hydrogen and petrol. The maximum output is 80kW (109PS) on hydrogen and 154kW (210PS) on petrol. The maximum torque is 140N・m (14.3kg・m) on hydrogen and 222N・m (22.6kg・m) on petrol. The fuel tanks can store up to 110 liters of hydrogen at a high pressure of 35Mpa and 61 liters of petrol. The drive range on the 10.15 mode is 100km on hydrogen and 549km on petrol. The standard lease price is 420,000 Yen a month including consumption tax. The vehicle was leased each to Idemitsu Kosan and Iwatani International Corporation in March 2006.

■Premacy Hydrogen RE Hybrid was displayed as a reference at the 2005 Tokyo Motor Show

  The Premacy Hydrogen RE Hybrid was displayed as a reference at the 2005 Tokyo Motor Show. It is a hybrid vehicle which combines a dual fuel rotary engine which can run on hydrogen and petrol with a hybrid unit comprising of a 30kW motor and nickel-hydrogen battery.

■Mazda started test runs of the Tribute Hybrid equipped with HEV system in the USA.

  The automaker is developing hybrid vehicles (HEV) combining petrol engine with electric motor in cooperation with Ford. In February 2006, 10 Tribute Hybrids were provided to the fire department of Irvine, California for test runs for two years. Another lot of 20 will be provided to fire department-related facilities in southern California.
  The Tribute Hybrid equipped with the MZR 2.3 liter engine can accelerate as fast as the Tribute with the V6 3.0 liter engine and its fuel efficiency in city driving is 74% higher than the base model. The Tribute Hybrid meets California's SULEV (Super Ultra Low Emissions Vehicle) and also AT-PZEV (Advanced Technology Partial Zero Emissions Vehicle), the most stringent emissions standard for petrol vehicles.

■Mitsubishi Motors: developing the next generation diesel engines and transmissions and starting to sell a minicar-based electric model by 2010

  In July 2006, Mitsubishi Motors announced a new plan for 2010, the Environmental Action Plan 2010. During the 2002-2005 period of the automaker's environmental sustainability plan, fuel efficiency improved and emissions became cleaner thanks to the introduction of CVT and renewed lineup of petrol engines for passenger cars. The CVT was installed in two-thirds of non-minicar vehicles sold in Japan in 2005, and vehicles above the 2 liter class began to have the new device, too. The new engines will make their appearance in new models as they are launched.

  On its way to meet the targets for 2010, Mitsubishi Motors will develop the next generation critical technology for lower fuel consumption, and put clean diesel engines and high-performance transmissions in new models.

  In addition, the automaker will expand its efforts in the area of resources and energy; vehicles which can cope with biofuel will be launched; green plastic derived from plants will be developed to be used in new models; a minicar-based electric model will be introduced into the market by 2010. With the advance of lithium-ion battery, electric vehicles are getting closer to reality, which will allow CO2 emissions to be reduced substantially compared with hybrid vehicles.

■Mitsubishi Motors: a new generation of petrol engines for passenger cars on its way

  The newly developed 3 liter V6 MIVEC engine for the Outlander was shown at the New York International Auto Show in March 2006. This completes the new generation of passenger car petrol engines, which is based on the common concept of high-performance, low fuel consumption, low emissions, and light-weight and compact in size. The engines will be installed in new models as they are launched.
  The new engine lineup, consisting of four types, features top-class maximum output and torque, a substantial weight reduction, improved fuel efficiency thanks to the introduction of variable valve timing mechanism (the MIVEC system) and aluminum cylinder block.
  The automaker is developing the next generation clean diesel engines as a critical technology to reduce CO2 emissions in order to meet new Japanese and European emissions standard.

■Mitsubishi Motors: the percentage of vehicles meeting the 2010 fuel efficiency standard is 76% for passenger cars and 98% for trucks.

  The percentage of vehicles produced in 2005 and meeting the 2010 fuel efficiency standard went up to 76% for passenger cars (69% for 2004), 98% for petrol engine trucks with AT (92% for 2004), and 98% for petrol engine trucks with MT (82% for 2004).
  The corporate average CO2 emissions in Europe for 2005 went down by 25% from the 1995 level thanks to the introduction of a greater number of fuel efficient new models and diesel engine models as well as the launching of the Colt, a compact car.

■Vehicles with CVT increased to two-thirds of non-minicar vehicles sold in Japan

  CVT was first installed in the Lancer in May 2000 and gradually spread to other models, with the Outlander with an engine larger than 2 liters being the latest model so equipped. As a result, two-thirds of non-minicar vehicles sold in Japan in 2005 are equipped with CVT.
  The Outlander uses aluminum roof to reduce the body weight. It is 5kg lighter than the steel version and contributes a lot to lowering the center of gravity, improving handling.
  The four speed AT of the i uses a torque converter with direct link which reduces the transmission loss of driving force at the time of acceleration and also expands the range in which fuel cut takes place, thus increasing fuel efficiency.

■Mitsubishi Motors: a minicar-based electric model will be launched for sale by 2010

  The automaker is developing a next generation electric vehicle based on minicar and aims to start selling it by 2010.
  The current lithium-ion battery weighing 150kg is capable of a roughly 150km travel (roughly four times the lead battery, twice the nickel-hydrogen battery) but the automaker expects the distance to be extended by a factor of 1.6 by 2010, increasing the possibility that electric vehicle can be used as a practical car.
  The automaker is developing a next generation electric vehicle equipped with in-wheel motors located inside the road wheels and also manganese system lithium-ion battery which is high-performance and much safer than other types. The automaker has already made some prototypes of the five seater Colt EV with in-wheel motors in rear road wheels and capable of traveling 150km, and some prototypes of the Lancer Evolution MIEV with 50kW in-wheel motors in each road wheel.
  According to Mitsubishi Motors, electric vehicles are capable of making a greater reduction of CO2 emissions (calculated at the time of power generation) than hybrid vehicles, and their fuel bills are much smaller than hybrid vehicles'. When electric vehicles are recharged during the daytime, their fuel bills are one-third those of petrol engine vehicles and two-thirds those of hybrid vehicles, with a lot more improvement expected when they are recharged during the night.
