Break new ground

Improved payload capacity

New Quester deliver huge payload possibilities. Optimized tare weight and driveline on New Quester have reduced the truck’s weight by almost half a tonne. 

Productive on any terrain

UD construction trucks are designed for agility in tough conditions. A front steel bumper ensures high ground clearance and approach angle, while robust chassis and tough rear leaf suspension reduce stress from uneven road surfaces and also when carrying unevenly distributed loads.


New Quester features PWR+ mode on ESCOT. This makes construction assignments more efficient, with increased power and high running performance in tough conditions. It features a rock loose mode for quick escape when stuck in slippery and muddy conditions.



Lower operating costs with ESCOT

Building on Quester's excellent fuel economy, New Quester's GH11E engine with ESCOT automated manual transmission (AMT) is a winning formula for increased fuel efficiency. 
Automated gear shifting makes New Quester easier to drive and more fuel efficient even for new drivers. Helping you make the break towards lower operating costs. 

Powertrain optimization

New Quester offer a wide choice of rear axle ratios for different applications. This delivers excellent fuel economy at cruising speed in top gear, with no compromise on performance.

Aerodynamic cab design

UD construction cabs are aerodynamically designed for increased fuel efficiency, reducing coefficient of drag by five per cent at highway speeds.

High torque: Low revs

UD Trucks for construction feature fuel efficient engines that minimize consumption via high torque delivered at low revs, for improved profitability on every assignment.

Easier driving with ESCOT

In average daily operations with a manual transmission, drivers need to shift 1,000 to 1,500 times per day. ESCOT automated manual transmission always selects the optimal gear, improving driver efficiency and focus regardless of skill level or experience. Stress and fatigue are also reduced.

Better comfort on the job

Designed for long days onsite, New Quester has air suspended driver’s seat and cab air suspension. This increases comfort when maneuvers are tight and the workload is heavy. Many adaptable features also make the  truck to suit a wide range of drivers by allowing the most flexible driving position.

Clean and simple driver environment

Our construction cabs are designed to minimize fatigue via well-planned ergonomics. A smart instrument cluster and information display provide exactly what’s needed to focus on the job in hand.



Increased visibility

All construction cabs provide excellent all-round visibility with large glass areas and strategically placed mirrors. Effective and protected headlights are positioned on the cab side panel, while there are two types of rear-view mirrors available on New Quester.

Stress-free braking

Both trucks offer first-class braking, handling and stability. New Quester features a reliable auxiliary braking system via UD Trucks Extra Engine Brake. This maintains safe speeds and delivers powerful braking. A hydraulic retarder makes downhill driving safer, while ESCOT brake max mode allows the transmission to continuously downshift for more effective use of the EEB.


Increased service life

Optional hub reduction rear axles increase service life in tough conditions. Effective suspension reduces stress on the chassis and superstructure, which can mean longer intervals between servicing.

Expert Story

Toshi Odawara, Vice President, UD Trucks Heavy Duty Product Line, talks about the unique qualities New Quester brings to the construction segment.

“ESCOT contributes to easy driving on tough terrain and greatly improves fuel efficiency.”

What do you think are the most important new features on New Quester for the construction industry?

Quester already has strong assets for the construction segment. It can easily cope with tough assignments, with its robust chassis and options such as the high ground clearance, steel bumper, hub reduction and tough drivelines capable of higher payloads. Additionally, we have added our in-house automated manual gearbox ESCOT, which contributes to easy driving in various road conditions and greatly improves fuel efficiency.

What makes the Quester essential for the construction market?

Construction assignments are diverse. The truck has to handle multi tasks and must be simple and robust. It operates in different conditions such as hilly and rough muddy roads to

For this we have added the PWR+ mode from Eco mode. This will provide smoother and stable gear shifting operations at slow speed in rough road conditions, such as on construction sites.

Allison is ideal for stop-start operations. Can you expand a bit on its qualities for construction in particular?
Allison is ideal for short haul trips where you have many stop-start operations. Construction assignments are often in cities and regional areas, and delivering ready mix concrete and other construction materials in these cities is challenging. Allison is suitable for this type of operation, as clutch maintenance costs are reduced and any driver can achieve good fuel efficiency.

What are the most important considerations in today’s markets?

“To focus on what customers’ essential needs are, and to provide the kind of truck that can fulfil those needs. Simple and robust, easy to maintain, keeps working, and low downtime. We don’t want customers to suffer with maintenance or downtime due to complex technology or systems, but to keep their asset up and running. We want customers to profit and be successful in their business by investing in our products. For drivers it’s all about ease of driving and a comfortable spacious cabin. The Quester excels on the essentials such as fuel efficiency and uptime. We have developed a wide range of offers and adaptations that ensure our customers get exactly the right truck for the right job. Today we see a solid growth in demand for the Quester. The feedback from our customers makes me really proud to be part of this journey.”
