So what is ESCOT?
ESCOT: The Benefits
How does it work?
How does it actually improve fuel efficiency?
First of all, internal energy losses are low - actually lower than on manual gearboxes. However it’s the electronics that really make the difference. When driving in ECO mode, every gear change is timed precisely, to let the engine work at its most efficient rpm range.
ECO-ROll
When in cruise control, the ESCOT ECO-Roll fuel-saving feature calculates when it is optimal for trucks to roll down slope in neutral. It maintains speed by automatically disengaging the engine when on flat or down slope. This makes use of the truck’s momentum instead of burning fuel.
Powerful and efficient performance
The engines deliver high torque and pulling power at low RPMs, while flat torque curve minimizes need for gear changing. Meaning higher average speeds and lower fuel consumption in the long run.
More power and performance when you need it:
GH8E
Available transmissions:
GH11E
Available transmissions:
Cruise control
Cruise control reduces driver workload on longer journeys and helps to reduce fuel consumption by maintaining a constant speed.
Electric viscous fan
