Fabrication of New Racing Truck Begins in Preparation for Dakar Rally 2013
HINO TEAM SUGAWARA will be entering two HINO 500 Series trucks in Dakar Rally 2013 which is to be held in January 2013. Car 1 will be developed as a new production truck-based racing truck that incorporates new systems as part of the team's efforts to aim for high position rankings in this rally. Car 2 will be an upgraded version of the truck that won the most recent of the three consecutive class championships in 2012. With regard to the development of these trucks, the team will combine TEAM SUGAWARA's accumulated expertise for developing rally trucks, and truck production technologies that Hino has cultivated over the years to take on the challenge of the world's most grueling race.
In this issue, we would like to introduce our readers to the new racing truck (Car 1) that is currently undergoing fabrication in preparation for entering Rally Mongolia 2012 (August 11-19) which has become a testing ground for the team.
<A Team First> Truck to be powered by "J08C" an electronically-controlled fuel injection (common rail) engine.
|For the first time in Hino's 21-year history in the Dakar Rally, this truck will be powered by an electronically-controlled fuel injection (common rail) engine to enhance torque in the mid to low ranges which is crucial in traversing sand dunes and rough terrain. While electronically-controlled fuel injection engines produce more output and offer more latitude in terms of configuring the output curve, we have seen no small number of rival trucks stopped by the road in the race as harsh conditions can often cause electronically-controlled safety devices (so called "limiters") to trigger as well as other problems with electronics. While this will be new territory for the Sugawaras who know Dakar Rally and Hino trucks inside and out, they are drawing from all the expertise of the Hino group and are committed to developing an engine that will deliver performance up to its limits even under harsh racing conditions.||
Engine awaits common rail upgrade.
New additions include axle with hub reduction function and disk brake system.
|The new truck is equipped with a new axle with hub reduction* function which increases its minimum ground height from the previous vehicle by 35mm (theoretical) as measured from the lowermost point of the axle. This axle is also now fitted with a disk brake system equipped with opposing 4-pot Brembo calipers that have a proven track record in various racing categories. Disk brakes help improve time as they generally involve fewer parts, are lighter than conventional drum breaks, and provide better braking response. However, because vehicles in the Trucks category are heavy and therefore impose more load on the brake disks causing them to heat up, there is greater risk of damage to oil seals and air seals in the hub, which are known to cause serious problems in the Dakar Rally even for the top teams.||
Axle with hub reduction function,
and disk brakes.
* Hub reduction: A design where reduction gears are incorporated into the wheel hub in order to increase minimum ground height, which is a crucial element in improving traversing capability over uneven terrain. This design allows for smaller differential gears enabling designers to reduce the diameter of the differential gear case and achieve a higher minimum ground height for the axle.
Wheels to be upgraded from steel to forged aluminum.
|The truck will now run on forged 2-piece aluminum wheels made by the American company, Hutchinson, achieving a weight reduction per wheel of 10kg compared to steel wheels. It continues to be equipped with the CTIS (Central Tire Inflation System), a system that is combined with the axle and allows the crew to adjust the tire air pressure remotely from the navigator's seat. With this system, the crew is able to adjust the air pressure to suit the road surface and improve terrain traversing capability.||

Frame and leaf spring characteristics to be modified.
|Because the modifications described above will have the effect of increasing the truck's speed over rough terrain, the main frame have been heightened to increase its rigidity.
The team will be racing in Rally Mongolia 2012 in a new racing truck that incorporates these new systems and with specifications from the truck that achieved the most recent of the three consecutive class championships in the Dakar Rally in 2012. The team will be gathering data on this real-world testing ground to make further improvements in preparation for the Dakar Rally 2013. HINO TEAM SUGAWARA will be boldly taking on these challenges as a year of trials, without fear of the risks, to reach even higher heights and prove to the world the "excellent durability and reliability" of Hino trucks.

<Topics> Team's Official Movie "The Heartbeat of the Dakar Rally 2013" is Released.
At the end of June, an official film was released which chronicles the efforts of HINO TEAM SUGAWARA as it prepares for the next race. The film features interviews with Kazuyuki Baba (General Manager, Engine Engineering Div.) who is in charge of developing the electronically-controlled fuel injection engine, the secrets to how "Iron Man" Yoshimasa Sugawara faces the challenges that come his way, and the enthusiasm of his son, Teruhito Sugawara. We hope you enjoy the film.

<Topics> Five Races for the 2012 Dakar Challenge are Decided.
The Dakar Challenge refers to a program that is based on tie-ins with prominent rallies around the world, where contestants who finish in high rankings in these rallies are invited to compete in the Dakar Rally. The Dakar Rally is the world's top cross-country rally and a "dream race" for amateur riders around the world. It is therefore intensely time and cost intensive just to even enter the race. True to the words of Dakar Rally founder, Thierry Sabine, "It is you who must open the 'door to adventure.' If you wish, I will take you there," the spirit of providing an opportunity to all people who pursue adventure is still alive in the Dakar Rally. Tie-ins were made with the following 5 events for 2012.
|July 22 - 28||Dakar Series Desafio Litoral (Argentina, Paraguay)|
|July 23 - 25||Toyota 1000 Desert Race (Botswana)|
|September 15 - 25||Taklimakan Rally (China)|
|September 21 - 29||Australian Safari (Australia)|
|September 29 - October 6||Pharaoh Rally (Egypt)|
