Honda Motor Co., Ltd. plans to begin public road demonstration testing of its driving support system utilizing traffic signal information next month. The demonstration testing will be conducted in Utsunomiya City, Tochigi Prefecture in Japan in collaboration with the Tochigi Prefectural Police and UTMS Society of Japan, as part of research and development of the Universal Traffic Management Systems (UTMS) in which Honda has been participating.
UTMS is a new traffic management system promoted by the National Police Agency of Japan as a part of Intelligent Transport Systems (ITS). The UTMS utilizes information communication technologies to realize safer and smoother traffic as well as to promote environmental protection. Honda’s large-scale road testing will help it verify the overall functionality and effectiveness of the system as the final stage of verification toward commercialization.
Honda recalls Fit Hybrids and Vezel Hybrids in Japan; 3rd recall due to problems with 7-speed DCT
February 10, 2014
Honda Motor Co., Ltd. announced a voluntary recall of the all-new Fit Hybrid (earlier post) and Vezel Hybrid (earlier post) produced in Japan from July 2013 through February 2014 due to a problem with the software program controlling the 7-speed dual clutch transmission (DCT) which could cause non-engagement of gears, a delay in the ability to begin driving or the inability to move at all. Honda notified Japan’s Ministry of Land, Infrastructure, Transport and Tourism of the recall with a total recall population of 81,353 units.
Honda conducted two earlier recalls in October and December 2013 due to a defect with the software program controlling the 7-speed DCT which could have caused a delay in the ability to drive the vehicle or the inability to drive. This latest recall is this the third related to problems with the 7-speed DCT. Each recall was due to a different cause.
Japan automakers going slow with biodiesel; JAMA maintains stance on B5 as maximum for now
January 22, 2014
The Japan Automobile Manufacturers Association (JAMA) is maintaining its stance on B5 (5% biodiesel, i.e., fatty acid methyl ester, blends) as the maximum until further findings and market observations on the use of B7 are reported.
JAMA bases its postion on the results of study from the Japan Auto-Oil Program subsidized by Japan’s Ministry of Economy, Trade and Industry (METI). JATOP was organized by the Japan Petroleum Energy Center to develop automotive and fuel technologies best suited to simultaneously settle three issues—“Reducing CO2 emissions”; “Fuel diversification” and “Reducing motor vehicle emissions”—and to develop high accuracy air quality simulation models and facilitating their exploitation.

In Japan, Toyota Motor Corporation launched the completely redesigned Voxy minivan through Netz dealers, and the completely redesigned Noah minivan through Toyota Corolla dealers; hybrid models are scheduled for release on 14 February. Monthly sales targets for Japan are 4,600 units for Voxy and 3,400 units for Noah.
For the hybrid variants, a 2ZR-FXE 1.8-liter Atkinson cycle combustion engine, evolved and matured from the third-generation Prius, together with a class-first full hybrid system (THS II with reduction gear) achieves fuel economy of 23.8 km/L (56 mpgUS, 4.2 l/100 km) and CO2 emissions of 98 g/km under the Japanese Ministry of Land, Infrastructure, Transport and Tourism’s (MLIT) JC08 test cycle.

Honda Motor Co., Ltd. began sales of the VEZEL in Japan today. Honda says that the VEZEL fuses the dynamic qualities of an SUV, the elegance of a coupe, the functionality of a minivan and excellent fuel economy.
The conventional VEZEL is equipped with a 1.5L direct-injection DOHC i-VTEC engine coupled to a CVT, as is available in front-wheel and four-wheel drive versions. The VEZEL HYBRID is equipped with Honda’s next-generation SPORT HYBRID i-DCD system (earlier post) that combines a 97 kW (130 hp), 156 N·m (115 lb-ft) 1.5 L direct injection engine with a 22 kW (30 hp), 160 N·m (118 lb-ft) motor. The realized maximum system output of 112 KW (150 hp) is equivalent to that of a 2.0-liter engine.
Mazda showcases CNG and hybrid Axela models in Tokyo; Mazda’s approach to environmental performance
November 22, 2013
At the Tokyo Motor Show, Mazda is showcasing the recently-released Mazda Axela (known as Mazda3 overseas) with a variety of engine types at the 2013 Tokyo Motor Show, including a CNG concept and hybrid variants. (Earlier post.)
The Axela accounts for more than 30% of global sales; the latest Axela is the third generation. The new Axela range also introduces a hybrid vehicle, and marks the first time for a single model launched on the Japanese market to include gasoline, diesel, and hybrid power plants in its powertrain lineup.
Mazda suspends dealership test drives showcasing Smart City Brake Support after injury accident
November 12, 2013
Mazda is suspending all test drives intended to showcase the accident avoidance features of Smart City Brake Support until the cause of an accident with injuries in Japan involving the technology has been established and countermeasures taken.
On 10 November, there was an accident causing injury to a customer and a dealership employee during a test drive event to demonstrate safety features using a Mazda CX-5. The demonstration was organized and held by a company called Sakata Jidosha Kogyo, which runs three Mazda Autozam dealerships in Japan’s Saitama prefecture.
Toyota, Nissan, Honda and Mitsubishi to provide financial assistance for EV charging infrastructure in Japan
Toyota Motor Corporation, Nissan Motor Co., Ltd., Honda Motor Co., Ltd., and Mitsubishi Motors Corporation have agreed on the details of specific financial assistance they will provide to installers of charging stations for electric vehicles (PHVs, PHEVs, and EVs). This announcement follows an agreement the four companies announced in July jointly to promote the construction of a user-friendly network of charging infrastructures. (Earlier post.)
In order for electric vehicles to become widely adopted, the partners point out, it is imperative that charging infrastructure be made widely available as quickly as possible. By assisting installers with the part of their costs not covered by government subsidies, the four companies intend to promote wider availability of chargers to make electric vehicle use more convenient.

In addition, there will be a special Corolla Fielder Hybrid G Aerotourer·WxB grade. Monthly sales target for Japan are 1,000 units of the Corolla Axio hybrid and 1,500 units of the Corolla Fielder hybrid.
The vehicles are equipped with a 1.5-liter hybrid system akin to that in the Prius c (earlier post) and that achieves a fuel efficiency of 33.0 km/L (77.6 mpg US, 3.0 l/100 km) under the JC08 test cycle of the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT).
Toyota, Nissan, Honda and Mitsubishi agree to joint development of charging infrastructure for plug-in vehicles in Japan
July 29, 2013
Toyota Motor Corporation, Nissan Motor Co., Ltd., Honda Motor Co., Ltd., and Mitsubishi Motors Corporation jointly announced their agreement to work together to promote the installation of chargers for plug-in electric vehicles (PEVs)—(plug-in hybrids (PHEVs) and battery-electric vehicles (EVs)—and to build a charging network service that offers more convenience to drivers in Japan. (Earlier post.)
The partners said the move is in recognition of the need for the swift development of a charging infrastructure facilities to promote the use of electric-powered vehicles. Assisted by subsidies provided by the Japanese government, the four automakers will bear part of the cost to install the charging facilities. They will also work together to build a convenient and accessible charging network in collaboration with companies that are already providing charging services in which each of the four automakers already have a financial stake.

A team from Japan’s RIKEN, led by Hye Ryung Byon, has developed a lithium-iodine (Li-I2) battery system with a significantly higher energy density than conventional lithium-ion batteries. RIKEN is Japan’s largest research organization, with institutes and centers in locations throughout Japan.
In a paper published in Nature Communications, they report that aqueous lithium-iodine batteries based on the triiodide/iodide redox reaction show high battery performance. The high solubility of triiodide/iodide redox couples results in an energy density of ~ 0.33 kWh kg−1. The reversible redox reaction without the formation of resistive solid products promotes rechargeability, demonstrating 100 cycles with negligible capacity fading.
