The trucks HINO races in the Dakar Rally - the "Little Monsters".
Based on the HINO500 Series trucks that are known for their world-class durability, these mid-sized racing trucks continue to fight fiercely against larger monster camions powered by engines with more than twice the displacement of the 500 Series engine. This is why these trucks, nicknamed "little monsters," have instilled fear and awse in their rivals. These trucks are currently being maximized the potential inherent in HINO trucks so that they will be ready to take on the race.

Outline of modification
Modified for higher revving and fine-tuned to meet regulations, including adjustments made to the injection pump, the engine with inter-cooled turbo revs up to the red zone with no stress whatsoever. In addition to easier handling, its durability and reliability are in classes of their own. This engine is literally the "motive force" behind HINO's record of consecutive finishes in the Dakar Rally. Combined with large wheels, the truck is able to reach speeds up to 140km/h.
Because the Dakar Rally weaves through areas where there are literally no roads, it would not be an overstatement to say that suspension settings determine the outcome of the race. Suspension settings must be fine-tuned to ensure that the truck is able to handle a variety of situations including driving over sand dunes and rocky terrain, as well as high-speed driving over gaps, all the while maintaining handling stability. The suspension has undergone countless improvements year after year, and currently uses a multi-leaf suspension. and shock absorbers by Reiger Racing per wheel.
|Central tire inflation system (CTIS)
This is a system that allows the navigator to adjust tire air pressure from the cabin while driving. Pressure is regulated with air from an air tank via an air-sealed hub bearing. During the rally, the navigator constantly regulates the pressure between 0.8 and 3.5 kg. The photo at right shows the control box for regulating pressure.
The rear body, whose side is combined with the cab for optimum aerodynamics, was made by Tsuboi Special Body and is the product of countless improvements. The outer shell of car 2 is made of tarpaulins. That of car 1 is made of the tarpaulin and carbon panels and is attached to the frame using a special glue. The fuel tank is securely attached to the cargo bed, and the truck also carries 2 spare tires, a minimum supply of spare parts, and the crew members' personal belongings. Reducing the number of spare parts onboard by careful selection is also an important part of the team's strategy.
The truck is equipped with 6 supplementary HID lamps. The HID lamps, which light the road ahead as bright as daylight, are critical in racing the Dakar Rally which involves extended night driving. Special films have been applied to these fog lamps and all other lights to protect them against damage from flying stones, and also provide protection while retaining light intensity.
The roll cage made of 70mm in diameter material fitted to the wide and high-roof spec cabin, racing bucket seats, and navigating instruments are tell-tale signs that this is a rally racer. However, because vehicles racing in the camion category are only allowed a minimum amount of modification -- such as modifications to safety equipment and navigation instruments -- the speedometer and dashboard are stock.
The bucket seats based on FIA regulation were specially improved cushioning. Seat selection is also an important aspect of racing in the Dakar Rally where racers must race for long hours. The entire windshield is protected against flying stones by a special film made by Seiko-Stella. The film is also effective in heat insulation and UV reduction.
Assisting camion HINO700 Series ZS
The HINO700 Series, HINO's world-class large trucks, are used to support the racing trucks, the transport of spare parts, and mechanics. The assisting truck is operated by “Japan Racing Management” and travels the bivouacs with mechanics riding in the truck that they are in charge of. One cannot keep one's eyes off of these trucks, either.
