Quester provides a winning formula for increased fuel efficiency. Introducing the new ESCOT automated manual transmission and updated engine, that helps you to maximize performance, with minimized operating cost. 460hp/2250 Nm engine now available in Euro5.
ESCOT – big news for Quester
A fast responding automated manual transmission that has built-in intelligence.
Quickly and automatically choosing the right gear at all times.
ESCOT: The Benefits
How does it work?
- ESCOT-E automated manual transmission features a non-synchromesh manual gearbox that has an electronically regulated pneumatic gear changing system and an automatic clutch.
- The secret of seamless gear changes lies in the intelligent electronic control unit, controlling the pneumatic system that handles the clutch and shifts.
- By constantly receiving information about speed, acceleration, weight, road condition, torque demand and more, ESCOT-E can carry out every shift with extreme precision.
- It also communicates closely with the engine to adjust revs and engine brake effect for fast, comfortable, fuel efficient gear shifts.
How does it improve fuel efficiency?
Internal energy losses are lower than on manual gearboxes. However it’s the electronics that 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.
Fuel Coach
The best way to improve driving efficiency in real time.
- All Quester models are equipped with a built-in fuel coach, an onboard solution clearly displayed at the centre of the 5-inch LED display, to give instructions in real time
- Fuel coaching encourages an optimal driving style at all times. It gives feedback and simple suggestions on how to improve safety and fuel efficiency, immediately and over the long term.

With extended ADR, Quester is regulated for safe transportation of hazardous substances. Additional features such as the UD Extra Engine Brake and the hydraulic retarder makes Quester a wise investment for safer operations.
Safety built in for you
Auxiliary brake
A reliable auxiliary braking system on Quester helps to maintain safe speeds and delivers powerful braking without fade.
The UD Extra Engine Brake (UD EEB) is a powerful engine brake that is optional with the 11-liter engine.
It back pressures the cylinders within the engine, using exhaust pressure and a patented ingenious valve system. There is no generation of heat or extra wear and tear on equipment.
Hydraulic retarder
The presence of the hydraulic retarder makes downhill driving easier. In loaded vehicles in particular, the vehicle speed can be controlled without applying the service brake. This reduces brake wear and prevents accidents due to brake fade.
Brake Max mode with ESCOT
When not coupled with a hydraulic retarder, ESCOT features a Brake Max Mode which allows the transmission to continuously downshift for a more effective use of the EEB.
ESCOT and Automatic (Allison)
Cutting out the need for manual gear-changing means drivers can keep their attention on the road. Therefore the addition of ESCOT and option of Automatic (Allison) in Quester are both good news for operational safety.
Other Quester braking functions include:
- Exhaust brake on GH8E and GH11E enables fast, reliable engine braking
- ABS (Anti-lock Braking System) improves braking on all surfaces
- Full S-cam air brakes are super-durable for constant use
High visibility rear view mirrors
Quester cab provides first-class all-round visibility and depending on customer preference or regulations there are two types of rear view mirrors, namely Japanese type and ECE certified.
Front Underrun Protection system
