01THE CHALLENGE
A credible answer to
an unusual brief.
INTERVIEW DESIGN CHALLENGE
Design a concept 4×4 bus for the Dubai market, with approximately 18 passenger seats and a visually distinctive—but technically credible—identity.
How can an off-road-capable vehicle transport passengers comfortably while still feeling premium enough for Dubai's tourism environment?
02DESIGN OPPORTUNITY
Two categories.
One new proposition.
01
Conventional bus
Comfortable and space-efficient
LIMITED OFF-ROAD CAPABILITY02
Off-road vehicle
Capable and terrain-ready
LIMITED PASSENGER COMFORTTHE RESPONSE
DUNE-X 18
03RESEARCH
Built on relevant
benchmarks.
The concept was grounded in existing commercial passenger and 4×4 platforms. Each reference contributed a specific lesson—not a styling template.
Mercedes-Benz Sprinter 4×4
Reference for 4×4 packaging and commercial component logic.
IVECO Daily 4×4
Heavy-duty drivetrain architecture and authentic off-road stance.

05DESIGN PHILOSOPHY
Rugged × premium.
Capability
4×4 · high clearance · all-terrain tyres · underbody protection
Comfort
Premium seating · panoramic glazing · high-capacity HVAC · low NVH
Identity
Champagne body · charcoal glasshouse · signature lighting · geometric fascia
The design intentionally avoids the appearance of a conventional city bus or a military vehicle. It combines the visual confidence of an off-road vehicle with the proportions and comfort expected from a premium passenger shuttle.

to decision.
20+THUMBNAILS
→03DIRECTIONS
→01SELECTED CONCEPT
SELECTED DIRECTION · CRugged
Strong capability cues, but the posture became too military for premium tourism.
Luxury
Refined and calm, but too close to a conventional coach and weak in terrain identity.
DUNE-X
The most credible balance of rugged, premium, and functional design priorities.
07EXTERIOR DESIGN
Every feature
has a reason.
SELECT A FEATURE
Signature LED lighting
A recognizable front identity built around conventional DRL, headlamp, and indicator functions.
08COLOUR & MATERIAL
Desert luxury.

SMOKED GLASS
Champagne / sand
Dubai, desert landscape, hospitality, and premium character.
Charcoal / black
Technology, protection, service interfaces, and mechanical hardware.
Continuous glasshouse
Windshield, side windows, and rear glass read as one visually lower passenger capsule.
094×4 ARCHITECTURE
Capability from
the inside out.
The body architecture was developed around the drivetrain—not treated as a styling shell with four-wheel drive added later.
POWER FLOW
Engine → transmission → transfer case → front differential + rear differential

Emergency
Exits + window breakers
Restraints

Interior
Non-slip floor + no sharp edges
REGULATORY BASIS
Dubai RTA bus requirements, UAE/GCC vehicle standards, and applicable vehicle type-approval requirements.
Concept design only. Final compliance requires detailed engineering, homologation, and RTA approval.12COMMERCIAL PARTS STRATEGY
Buy what is validated.
Design the difference.
The vehicle is intentionally planned around established commercial systems wherever possible—reducing tooling, validation, development time, and spare-parts complexity.

14ENGINEERING CHALLENGES
The difficult parts
are part of the story.
4×4 packaging
Transfer case, prop shafts, differentials, suspension travel, and service access compete for the same underfloor volume.
Vehicle weight
Added capability increases mass and axle load while passenger, luggage, HVAC, and glazing payload must be protected.
Dubai thermal load
A large glazed passenger cabin creates a demanding pull-down and steady-state cooling requirement.
Panoramic glazing
More visibility improves the experience but raises heat gain, mass, optical, and tooling challenges.
Body / chassis integration
Off-road torsional loads can drive fatigue, seal, fit, and NVH problems through the custom body.
