Subaru the Environment

Fuji Heavy Industries the maker of Subaru cars, tackles the challenge of meeting ever tougher environmental standards with a detailed corporate social responsibility policy that is at the heart of everything they do.

FHI president and CEO Kyoji Takenaka says: To address environmental issues, we set our management goal to become an eco-friendly company. Based on the idea of offering our customers clean products from a system of environmentally clean factories, logistics networks and distributors, we have been working to conserve the global environment by developing a new voluntary plan for the environment called the FHI Environmental Conservation Program (fiscal years 2002-2006). We have achieved outstanding results to date, particularly in waste reduction and energy conservation in the production stage.

Since the Kyoto Protocol became effective in 2006, further reduction of CO2 is required in industry, transportation and consumer goods around the world. As a result of FHI’s plan for the environment, the company has reduced CO2 levels even further than planned by promoting energy conservation at the plants and by introducing a natural gas cogeneration system. FHI is also focused on reducing CO2 emissions in their Subaru motor vehicles by improving fuel economy through weight reduction technologies.

Although it is producing more vehicles, Subaru’s factories use 28 per cent less energy than they did in 1990. By 2008 the vehicles will already meet fuel economy standards in Japan, the United States and Europe which do not have to be met until 2010.

Producing ‘greener’ cars occurs at all steps in the process at Subaru, from development and design, through manufacturing, servicing and ultimately disposal at the end of the vehicle’s life. In January 2005, the law on Recycling End-of-Life Vehicles came into force in Japan. FHI seeks to not only comply with this law but also develop products that are easier to recycle. By 2015 Subaru expects to be able to recycle 95 per cent of every vehicle it manufactures.

The use of mercury, cadmium, hexavalent and chromium has been deleted from the manufacturing process and lead is only used at just 10 per cent of what it was a decade ago.

The vehicles themselves are now being designed and built so they are easier to dismantle and separate the metal, glass, plastic and other materials. Subaru, together with most other major manufacturers in Japan, has established a partnership company to recycle fluorocarbons, airbags and other difficult to deal with parts from vehicles.

95 per cent of Subaru’s outside suppliers also meet the same environment management standards as Fuji Heavy Industries’ own facilities. The types of plastics used are now identified subtly on the outside, rather than the need to take the part off the car before identifying what it is. Instead of being dumped, the paint sludge from the giant paint troughs all vehicle bodies go through is now used to make vibration absorption panels for the floor of the vehicles.


Over the last eight years wastage in the painting process has been reduced by 57 per cent.

The motor industry is also using waste from other industries. Nylon fishing nets are being turned into engine covers, while scrapped bumpers are being remanufactured into cabin trim, battery pans, splash trays for under the motor, tailgate trims and luggage shelves in wagons and hatches.

Processes have been developed to get the plastic out of laminated windscreens, so the glass can be re-cycled. Until recently, laminated screens, which meet safety regulations, had to be dumped.

And longer service intervals means less consumable products are being used in the life of a vehicle.

It is now possible to produce electric power from renewable energy sources with less environmental impact, such as solar, wind, water and geothermal power, but the challenge is how to store the electricity for maximum efficiency and effectiveness. From around 2002, the company channelled millions of dollars into research and joined with NEC Corporation to establish NEC Lamilion Energy Ltd (NLE) as a planning and development company for high-performance manganese lithium-ion batteries.

Subaru Petrol/Electric Hybrid Engine

Subaru R1e — Electric Vehicle

At NLE, they worked on the development of secondary batteries for hybrid vehicles. electric vehicles, and fuel cell electric vehicles. Their long-life high performance batteries are good for ten years or approximately 240,000 km. It’s called the NLE lithium-ion battery and its ability to recharge very quickly attracted attention from Toyota Motor Corporation which then purchased 8.7 per cent of FHI’s shares in 2005.

This collaboration with Toyota has seen FHI determine some new goals to provide customers with alternatives to petrol-driven engines. Rather than continue their own hybrid petrol/electric engine development programme at this point, FHI has elected to adopt Toyota’s hybrid power train technology for the planned Subaru hybrid models in the medium to long term.

In 2006 Subaru completed a prototype of an electric vehicle being jointly developed with Tokyo Electric Power Co. Inc. (TEPCO) – the Subaru R1e. Based on Subaru’s Japanese-market-only micro R1 car, the electric version has a top speed of 100 km/h and utilises thin, high-performance lithium-ion batteries capable of running approximately 80 km on a single charge.

Subaru designed and manufactured the vehicle and TEPCO developed a high-speed charger. In 2007 FHI was awarded the Minister of the Environment’s 2006 Commendation for Global Warming Prevention Activity for its development of the Subaru R1e electric vehicle in conjunction with Tokyo Electric Power Co. Inc. (TEPCO) and NEC Lamilion Energy, Ltd.

Another outcome from Toyota taking a shareholding in FHI has been FHI’s ability to concentrate on developing their first diesel engine. Subaru chief executive Kyoji Takenaka said: “Because we’re a small company, we had to choose between hybrid and diesel. Now that we have this arrangement with Toyota, diesel engine development and production are going to be our priorities.”

Subaru Turbocharged Boxer Diesel Engine

FHI engineers continue to work on improving fuel efficiency with the current Subaru models. The current Legacy is a graphic demonstration of the problems in developing a new car. To meet the latest safety requirements, Subaru calculated the car would have to be 130kg heavier than its predecessor. Instead the new Legacy is on average, 100kg lighter.

The new car is stronger thanks to the use of different materials and construction methods, which have in total saved about 230kg.

Making vehicles lighter is one way to save fuel, which can be complemented, by the development of more efficient motors, reducing the amount of friction in the driveline and using gearboxes with more gears so the motor will perform more economically. The change to a single turbocharger, producing better, yet more economical performance saved 30kg alone in the latest Legacy GT models.

Another fuel efficiency innovation is Subaru intelligent Drive (SI-DRIVE). The new 2007 Legacy GT, 3.0R and Outback 3.0R models feature the revolutionary technology. Put simply, it is like having three engines in one car. SI-DRIVE allows the driver to choose from three different engine settings from the touch of rotary dial located centre console – Intelligent (I), Sport (S) or Sport Sharp (S#).

This advanced system, adjusts the computer mapping in the Engine Control Unit (ECU) whist also regulating the Transmission Control Unit (TCU) in an effort to either maximise fuel efficiency or maximise performance depending upon the mode selected by the driver.

On the fuel-efficient Intelligent (I) mode, the system selects a more relaxed throttle response. By controlling throttle angle and response of the Electronic Throttle Control (ETC) thus maximising planet-friendly fuel efficiency. Intelligent mode delivers up to 10 per cent improvement is real world fuel consumption. To read more about SI-DRIVE click here .

Ethanol suitability for Subarus

Most Subarus purchased new in New Zealand since 1990 are capable of running on the ethanol blended fuel now being introduced to the local market.

However any Japanese domestic specification models which have been imported here second hand (i.e.). second hand Japanese imports — should not be run on the ethanol blended fuel.

These cars are only suitable for 3 percent blended fuels. The fuel being sold in New Zealand has a 10 percent ethanol blend.

The 10 percent ethanol blended fuel could cause damage to the fuel line, fuel injector sealing, fuel pump or fuel regulator of these second hand Japanese imports. The fumes from the blended fuel after combustion can also have a harmful effect on the catalytic converter, the exhaust gas regulator and the muffler.

Those Subarus which can use the 10 percent ethanol blended fuel have a 17 digit VIN number beginning with either JF1 or JF2. The VIN number can be found at the bottom of the central door pillar on the passenger’s side of the car or in the engine bay.

The second hand Japanese imports which should not use the ethanol blended fuel have VIN numbers starting with 7A8.

A small number of models sold new in New Zealand cannot use the 10 percent blended fuel. They are.-

Legacy RS, Legacy GT, Legacy GTB, Legacy RSK and Legacy Blitzen from 1990 onwards; the Impreza STI from 1997 onwards and the Forester STI. They do not have JF1 or JF2 VIN numbers.

Owners who are not sure if they can use the ethanol-blended fuel in their car should consult their nearest Subaru Authorised Dealer.
