UD Trucks Quon

The UD Trucks Quon is a truck range that UD Trucks lists under heavy duty on its global site, together with the UD Trucks Quester. The specs page counts 13 models: ten with the 11-litre GH11 engine and three with the 8-litre GH8F, listed for FMCG, tilt tray and tipper work, for B-double applications and as a semi-trailer tractor. This page is built from UD Trucks’ own Quon pages on udtrucks.com, in the site’s Global market view: the specs page, read on 4 November 2026, and the overview, 8-litre engine, drivability, fuel efficiency, productivity and safety pages, read on 14 November 2026. None prints a date of its own. The pages call the truck “the Quon with new features” and “the New Quon”; no document opened gives its launch year or describes earlier generations.

Overview and range

The overview page heads the range “Innovation that puts people first”, and the specs page says this “next-generation of trucks” carries design enhancements in five major areas.

The specs page prints each model’s emission regulation: Post Post New Long Term on the CD 25 400, CD 25 360, GW 26 430 and GW 26 460; Post Post New Long Term and Euro VI on the CG 32 400 and CG 30 360; pPNLT / Euro VI on the CG 32 460, CG 32 430, CW 26 430 and GK 17 430; and Post New Long Term on the CW 26 400, CW 25 360 and CW 26 460. How wheel formulas are written is covered in axle configurations explained.

The 8-litre engine page describes three versions for Australia: the CD25 360VAA for rigid FMCG general freight and refrigerated cargo; the CW25 360LAA for local government, waste, rear compactors and metropolitan tipper landscaping; and the CG30 360, which UD Trucks calls “tailor made for the Australian market”, with a high tensile steel chassis frame, for waste and agitators.

Cab

No document opened names the Quon’s cab versions or gives cab dimensions. The 8-litre engine page mentions a short cab model and says it allows cargo with a legal length of over 10 meters on the loading platform; the drivability page mentions sleeper cabins. UD Trucks says the exterior design guides airflow smoothly from the flat front face to the corners, which it says reduces drag. Entry is by a wide two-step entry/exit with a long cab entry grab handle; the safety page places the long grip on the driver’s side.

The drivability page describes a four-spoke steering wheel with switches for functions and information, and a 5-inch color LCD multi-display in the centre of the instrument panel, with the information arranged in zones by warning priority, the most important at the top; a sub-display is among the panel’s labelled parts. The dashboard is finished in black and silver, and its switches light up when in use and at night. The Belt-in Seat (BIS) integrates the seat belt into the seat body and follows the movement of the seat suspension; UD Trucks lists it as an option for sleeper cabins.

Engines

The specs page lists two engines: the GH11 on the ten 11-litre models, at 400, 430 and 460 PS, and the GH8F on the three 8-litre models, at 360 PS. No document opened gives kilowatt figures, cylinder counts or a displacement more exact than the names 11-litre and 8-litre.

The overview page says the GH11 uses unit injector and common rail technologies for strong low-speed torque, with an advanced fuel injection system and an optimised combustion design. The fuel efficiency page adds a lightweight Variable Geometry Turbo Charger (VGT) and says the GH11 delivers up to 2.5% improvement in fuel efficiency.

The 8-litre engine page names the engine GH8, where the specs page writes GH8F. It describes a downsized engine, lightweight and compact, with a simpler structure, that generates powerful torque in a wide revolution range. It says the GH8 engine complies with Japanese 2016 exhaust gas regulations and that all high payload models achieve a 5% improvement over modern fuel efficiency standards. How PS, kW and torque figures relate is set out in reading truck power figures.

Transmission

Every model on the specs page lists the ESCOT-VI, which the fuel efficiency page describes as a 12-speed automated manual transmission; the CG 30 360 also lists an Allison 6-speed automatic. UD Trucks says the ESCOT-VI’s hardware and software control gives fast and accurate gear changes and suppresses fluctuations in fuel efficiency, and that performance is improved on uneven surfaces and muddy roads. The gear lever has a straight shift pattern with the positions R (reverse), N (neutral), D (drive) and M (manual), and a +/- button on its right side for changing up and down. The fuel efficiency page names a GPS-based gear prediction function, Foretrack. No document opened gives gear ratios. The principle of these gearboxes is explained in automated manual transmissions.

Chassis and suspension

The productivity page says the Quon uses disc brakes and high tensile steel plates for the main frame to reduce vehicle weight, and gives the chassis as designed for maximum payload, with the footnote “Up to +200kg depending on the model”. It describes an uneven load-adjustment function that maintains frame strength and chassis designs that emphasise body-mounting efficiency, and it lists aluminum bodies with gullwing doors, a gullwing body with a direct-drive refrigerating unit, and tipper and mixer bodies. The 8-litre engine page gives the CG30 360 a high tensile steel chassis frame.

A new air suspension has an increased height adjustment range, with an adjustment width of +140 mm upward from the neutral position, for loading docks and connecting trailers. On trucks with the new air suspension, the uneven load adjustment function automatically adjusts lateral differences in height, which UD Trucks says improves handling when loading from the side. The fuel efficiency page lists a new differential axle carrier. No document opened gives axle ratings, axle ratios or the suspension of each model. How air suspension holds and changes ride height is explained in ECAS air suspension.

Brakes

The drivability page says disc brakes are available on all models and names brake blending and the Emergency Braking System (EBS) among the systems it combines for braking comfort. The safety page describes the disc brakes as having high heat dissipation and fade resistance and lists Safe Brake Blending, which balances the main and auxiliary brakes through the brake pedal. It describes the UD Extra Engine Braking (UD EEB) function on the GH11 engine, which keeps engine rpm high for auxiliary braking; on the specs page the UD Extra Engine Brake appears in the braking rows of the two 8-litre models CD 25 360 and CW 25 360. The safety page also lists an Emergency Brake Signal, which warns road users behind with rapidly blinking brake lights in an emergency stop. How these auxiliary brakes work is explained in retarders and engine braking explained.

Dimensions and weights

The weights on UD Trucks’ Quon pages are those in the table under Overview and range: GVW from 17.0 Ton on the GK 17 430 4x2 to 35.3 Ton on the CG 32 8x4 models, and GCW of 55.00 Ton on the GW 26 430 and 60.00 Ton on the CG 32 models and the GW 26 460. The CW 26 430 and CW 26 460 rows give GCW 26.00-55.00 Ton and GCW 26.00-60.00 Ton, and the CD 25 360 row GVW 22.0-25.0 Ton. The specs page prints “Ton” without defining it.

The 8-litre engine page offers the dry wing version in two body types, standard and high payload, and says the high payload model, with a lighter chassis, has its payload increased by approximately 500-700 kg; its footnote reads “Comparison to UD GH11 engine mounted truck”. Under the heading “Improved payload of more than 500 kg” it lists 14,600 kg for the standard model and 14,800 kg for the high payload model of the CD 6×2, and 14,500 kg and 14,700 kg for the CG 8×4, without naming which weight these are. No UD Trucks document opened gives overall dimensions, wheelbases, a kerb weight, axle ratings or tank volumes. What the weight terms mean is set out in truck weights: GVW and GCW.

Safety and driver-assistance systems

UD Trucks groups the Quon’s safety systems as active, passive and basic, and says the Quon with new features embodies its ambition to achieve “Vision Zero: a future with zero injuries or fatalities from road collisions”.

The SAFES CABIN is built with a rigid body and side-door beams and redirects collision impact to the rear. It has seat belts with pre-tensioners, SRS airbags and an impact-absorbing steering wheel and column, and UD Trucks says it complies with the ECE R29 test. Under-run protection is fitted at the front. The 8-litre engine page says the 8-litre Quon has the same features as the 11-litre and names Traffic Eye Brake, UD Stability Control and the Lane Departure Warning System.

Fuel-efficiency functions and connected services

The fuel efficiency page says ECO mode, ESCOT Roll, the Acceleration Limiter, Soft Cruise Control and other features turn on automatically when the engine is running. ESCOT Roll comes on automatically in ECO mode when the gear lever is in D, the exhaust brake switch is off and the truck is coasting in 7th gear or higher on a flat road; UD Trucks says it reduces fuel consumption from re-acceleration while coasting, and it cancels automatically if the truck goes too fast with Traffic Eye Cruise Control on. The Acceleration Limiter limits sudden acceleration above a certain level and is lifted with the ECO OFF switch on the steering wheel, and Soft Cruise Control suppresses sudden acceleration when returning to the set speed. Idle Shut Down stops the engine after a few minutes of idling during parking.

The Nenpi Coach analyses driving patterns over a set period and shows fuel efficiency advice on the multi-display; it sends fuel efficiency information from the truck to the UD Information Service, which provides monthly fuel efficiency results and driving evaluations for each vehicle. UD Connect, part of the UD Information Service, provides vehicle operational data and location information. The fuel efficiency page also names an improved driveline, an enhanced fuel sending unit and UD Driver Development tools and lessons for drivers, and the overview page names UD Extra Mile Support and UD Road Support.
