Efficient, clean and powerful GH11 engine

The GH11 engine’s new fuel injection system uses both a unit injector and common rail system.

  • Generates power torque in a wide revolution range, starting from low revolutions
  • Light-weight, high performance Variable Geometry Turbo Charger (VGT) with excellent response, for responding to detailed accelerator work
UD Trucks All-New Quon ESCOT

ESCOT-VI for enhanced fuel efficiency

ESCOT-VI", provides advanced gear change control and suppresses fluctuations in fuel efficiency. Enhancements to hardware and software control achieve fast and accurate gear changes. Quick and smooth gear changes reduce the driver’s level of stress and fatigue and contribute to safe driving. Performance is also improved on uneven surfaces and muddy roads.

This function enhances fuel efficiency while coasting, by reducing the consumption of fuel due to re-acceleration. It is enabled automatically if certain conditions* are satisfied while in ECO mode. Furthermore, if the vehicle speed gets too fast when Traffic Eye Cruise Control is ON to control the optimum speed for maintaining distance with the preceding vehicle, ESCOT Roll is cancelled automatically.
* When the gear lever is in the D range, the exhaust brake switch is OFF, and coasting in 7th gear or higher on a flat road.

Acceleration Limiter

Sudden acceleration above a certain level is limited, even when flooring the accelerator pedal, in order to enhance fuel efficiency and maintain stable driving. Further, in situations where acceleration is required, the driver can turn ON the ECO OFF switch on the steering wheel to enable ECO OFF mode and remove the limitation on the truck's strong acceleration.

Soft Cruise Control

If the Cruise Control switch is turned ON while in ECO mode, Soft Cruise mode is enabled. This function provides excellent fuel efficiency by changing the vehicle speed to a gentle acceleration based on the load on the engine when driving at a constant speed.

UD Trucks All-New Quon Nenpi Coach

"Nenpi Coach" for fuel-efficiency advice

The "Nenpi Coach" system analyses 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.
UD Trucks All-New Quon Nenpi Coach report

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
