Fuel efficiency


Advanced fuel-efficient driveline 

The improved driveline achieves high level of fuel efficiency that enhances transport efficiency. Both fuel-efficient, powerful and clean ”GH11 engine” and ”GH8 engine” with light-weight and compact while powerful torque comply with Japanese 2016 exhaust gas regulations and all high payload models achieve +5% over the fuel efficiency standards. ESCOT-VI’s road predictive function ”Foretrack”* and “Nenpi coach” advice support fuel-efficient driving. * Standard for GH11 engine mounted truck


Efficient, clean and powerful GH11 engine

The GH11 engine’s new fuel injection system uses the unique properties of both unit injector and common rail system.  

1. Generates power torque in a wide revolution range, starting from low revolutions
2. Light-weight, high performance Variable Geometry Turbo Charger (VGT) with excellent response, for responding to detailed accelerator work


Light-weight, compact and powerful “GH8 engine”

With downsized engine achieving light-weight and compact, and simpler structure maintaining high reliability, it generates powerful torque in the whole area. It both achieves light-weight as well as high payload and powerful drives. It complies with Japanese 2016 exhaust gas regulations and all high payload models achieve +5% over the fuel efficiency standards.

ESCOT-Ⅵ road predictive function for enhanced fuel efficiency

The ESCOT-Ⅵ 12-speed automated manual transmission suppresses fluctuations in fuel efficiency. Further evolution in hardware and software control has achieved enhanced fuel efficiency with quick response. The Foretrack road predictive function enhances fuel efficiency when the vehicle drives with high speed on the climbing up and down slope road.


ESCOT-Ⅵ road predictive function for enhanced fuel efficiency

When using cruise control (at 60 km/h or more) in ECO mode, this function enhances fuel efficiency on hilly roads. Using GPS, road gradients are scanned and saved to predict road conditions when driving the same roads again. Automated optimal control of vehicle speed, engine rpm, and auxiliary braking ensure comfortable, safe, and eco operation regardless of driver skill.


"Nenpi Coach" for fuel-efficiency advice

The "Nenpi Coach" system analyzes driving patterns for a specified time period, then displays optimal fuel-efficiency advice on the multi-display monitor in an easy-to-read format. The driver can also check other detailed info and optimal driving techniques to improve fuel economy.


Fuel efficiency report for enhanced fuel efficiency

The UD Information Service receives fuel efficiency information that is calculated with the Nenpi Coach directly from the truck, and provides fuel efficiency results and driving evaluations on a monthly basis for each vehicle.

Features of the fuel efficiency report:
1. Efficient improvement of fuel consumption by linking the fuel efficiency reports with the Nenpi Coach

2. Fuel efficiency is calculated based on remote information from the vehicle, without the need to enter the volume of fuel supplied

3. Specific advice provided for each driving category, such as the green zone, top gear, ESCOT and use of cruise control

4. Fuel efficiency values and scores for the past 13 months graphed in chronological order
