Hino Motors, Ltd., releases heavy-duty truck Hino Profia

in compliance with the New Long-Term Emission Regulations of Japan.

- Comprehensive upgrade in product competitiveness in terms of environmental performance, fuel efficiency, safety performance, etc. -

Hino Motors, Ltd. (“Hino”) has improved the fuel efficiency of the heavy-duty truck Hino Profia to comply with the New Long-Term Emission Regulations of 2005 and also improved product competitiveness through safety and other performance with the launch sales planned for February 20, 2006.

The new model Hino Profia features the sophisticated clean diesel system DPR (Diesel Particulate active Reduction system), which has been further evolved through Hino’s advanced engine development technology, while environmental performance, including broad reductions in NOx (nitrogen oxides), PM (particulate matter), etc., has been improved.

Hino’s unique DPR is a system that improves environmental performance while maintaining the ease of use of diesel vehicles without constraints due to infrastructure since it requires no filling material other than fuel (diesel fuel).

In addition, vehicle weight is also maintained at the same level as conventional vehicles, assuring load capacity at the top of its class.

It is furthermore equipped with the straight-6 cylinder diesel engine E13C with turbo-intercooler, developed based on the low-consumption engine concepts with the aim of responding to the demands of society for the reduction of CO2 emissions based on the Kyoto Protocol and the demands of customers for better economic efficiency through lower fuel consumption.

It is a truck that boasts of both environment performance and fuel efficiency and assures outstanding fuel efficiency at the top of its class through the synergistic effect of the engine, which demonstrates high torque from the low RPM range, “Hino Eco-Run”, which controls acceleration by computer and constrains wasteful fuel consumption, and the semi-automatic transmission “Pro Shift 12”, which realizing optimal engine fuel efficiency.

Moreover, the heavy-duty semi-tractor to be released at the same time is equipped with the vehicle stability system VSC (Vehicle Stability Control)*2, the first of its kind in Japan*1, assuring control of unstable vehicle conditions in the direction of stability and high-dimensional safety performance for problems unique to truck tractors including overturns, jackknifing*3 and drift-out*4.

In addition to the environmental performance, fuel efficiency and safety performance of an environmental and safety frontrunner, overall product competitiveness of the new model Hino Profia has been improved through the installation of a large reinforced rear bumper as standard equipment*5 and compliance with the illumination device safety standards of 2006, providing the customer with a truck offering greater benefits.


1) First acquisition in Japan of certification of the Ministry of Land, Infrastructure and Transport as a vehicle stability control system for heavy-duty tractors.

2) The Toyota Group (Toyota Motor Corporation, Daihatsu Motor Co., Ltd., Hino Motors, Ltd.) has positioned VSC as a key technology of the reduction of traffic accidents.

3) Tractor and trailer jackknifing that occurs when driving into a rut on slippery road surfaces.

4) A phenomenon in which the vehicle slides off the track without getting front tire grip, thereby failing to make curves on slippery road surfaces.

5) Excluding tractors.

Ⅰ.Characteristics of the vehicle

1. Further evolved environmental performance

1) Equipped with the newly developed straight 6-cylinder diesel engine E13C utilizing a high-pressure common rail fuel injection system, combined EGR consisting of high-efficiency cool EGR and electronic-controlled pulse EGR and electronic-control variable nozzle turbo

2) Engine improvements realize optimal continuous control of intake air volume and EGR (emission gas recirculation) while broadly reducing NOx

3) The coordinated control of the clean diesel engine and aftertreatment device DPR Cleaner, which boasts of 95% PM capture rate, is a further advancement of the clean diesel system DPR which burns captured PM.

4) Compliant with the following diesel regulations, designations and certification programs

(1) New Long-Term Emission Regulations (2005)

(2) “Excellent Low-Emission Vehicle” designation in the Low-Emission Vehicle Designation System promoted by Tokyo, Chiba, Saitama, and Kanagawa Prefectures, and the cities of Yokohama, Kawasaki, Chiba, and Saitama

(3) “Lev-6” designation in the LEV-6 Low-Emission Vehicle Certification System promoted by Osaka, Kyoto, and Hyogo Prefectures as well as the cities of Osaka, Kyoto, and Kobe

2. Outstanding fuel efficiency

1) The new engine, developed based on low fuel consumption engine concepts, demonstrates high torque in the low RPM range and improves fuel efficiency.

2) It assures fuel efficiency at the top of its class through the synergistic effect of the semi-automatic transmission Pro Shift 12, which optimally realizes outstanding fuel efficiency of the engine, and the eco-drive devices described below, etc., and contributes to the improved economic efficiency of the customer and reduced CO2 emissions.

(1) ”Hino Eco-Run”, computer control of acceleration (standard equipment)

・Automatic constraints in the engine on wasteful fuel consumption due to rough accelerator operation through the computer control of acceleration

(2) Speed limiter capable of random setting of speeds limitations (standard equipment in some models)

- In addition to conventional speed limiter functions (standard equipment in all models), the highest speed can be set randomly within the statutory speed limit in vehicles with auto-cruise functions.

- In addition to fuel economy effects, it contributes to the maintenance of safe speeds.

(3) ”Hino Drive Master”, which supports the establishment of eco-driving practices (optional)

- This is an eco-drive support system consisting of a single vehicle-mounted terminal only with no need for PCs or other incidental devices.

- It supports the establishment of eco-driving practices through “alarms regarding fuel wasting vehicle operation” while driving and “driving guidance based on printout data of driving conditions” after the conclusion of operations.

3. Advanced safety performance

1) The vehicle stability control (VSC)*2 system is installed in the tractor (optional)

(1) High vehicle control performance is demonstrated on icy or other slippery roadways through the coordinated ABS action of the tractor and trailer for unique tractor problems of overturn, jackknifing*3, drift-out*4 and other conditions of vehicular instability.

(2) Unstable conditions are detected in advance and the driver is warned by alarms while vehicle conditions are controlled in a stable direction through engine output restrictions and braking action.

(3) Hino has contributed to the control of overturn accidents by providing Roll Stability Assist, which controls overturns, since the release of heavy-duty semi-tractors in November 2003 and, through the VSC, a further advancement, comprehensive control of stability is realized.

2) Response to amended safety standards for roadway transport vehicles

(1) A heavy-duty reinforced rear bumper is provided as standard equipment*5 in response to the mandatory installation of underrun prevention devices (rear bumpers)

(2) Vehicle lamps are in compliance with the illumination device safety standards of 2006.

3) Safe operation is supported both in terms of active (preventive) safety and passive (collision) safety through the installation of “high-rigidity aegis cabs”, “front underrun protectors”, “scanning cruise”, “lane departure warning system”, “left and rear auxiliary cameras”, “tire pressure monitors” and so forth.

4. Enhanced cab variations

The standard cab, high-roof cab with improved interior comfort and aerodynamic performance, short cab with outstanding loading rate, short cab super high-roof cab with bed space high in the cab and roof cut cab, which allows the installation of large-scale freezer units, are available in response to the diverse needs of the customer.
