Is the Isuzu MU-X suitable for off-roading? In this Isuzu MU-X off road review, we answer that question with a resounding yes, backed by our first-hand test on the Mundaring Powerline Trail—one of Western Australia’s toughest 4WD tracks.
At Elite Tune, 4x4s are our specialty, and we’re passionate about helping Perth’s off-road enthusiasts unleash their vehicle’s full potential. I recently pushed the MU-X to its limits on this iconic trail, tackling steep inclines, rocky outcrops, and sandy stretches.
With decades of experience at our Welshpool workshop, we’ve tuned countless MU-Xs, and this comprehensive review dives into its off-road capabilities, limitations, and how our tailored upgrades can transform it into a trail-dominating machine.
Summarised Isuzu MU-X Off Road Review
- Powerful Performance: The 3.0L turbo-diesel (140kW, 450Nm) and advanced 4WD system with rear diff lock and Rough Terrain Mode (RTM) mastered Mundaring’s steep climbs and muddy ruts.
- Robust Specs: 235mm ground clearance, 29.2° approach, 26.4° departure, and 800mm wading depth handle most off-road challenges, ideal for trails and family adventures.
- Limitations: Stock highway tyres struggle on loose terrain; underbody protection is needed for extreme conditions like Mundaring’s rocks.
- Verdict: The MU-X is highly suitable for off-roading, from moderate trails to hardcore tracks, especially with our custom upgrades.
Engine Power
The MU-X I tested was powered by the 3.0L turbo-diesel engine, delivering 140kW and 450Nm of torque. On Mundaring’s steepest incline—a 30-degree climb littered with loose rocks—the engine’s grunt shone through, pulling me up with smooth, controlled power. The six-speed automatic transmission ensured seamless delivery, even in low-traction scenarios. The 1.9L turbo-diesel option, with slightly less torque, is still capable but better suited for lighter off-road duties. During the test, the 3.0L’s torque made short work of towing a small trailer over uneven terrain, proving its versatility for family adventures or heavy-duty tasks.
4WD System
The MU-X’s 4WD system is a standout for off-roading. It features High-Range and Low-Range modes with a 2.482:1 low-range ratio, multiplying torque for maximum traction. On a muddy descent on Mundaring, I engaged Low-Range, and the MU-X crawled down with pinpoint control, avoiding wheel spin. The mechanical rear differential lock was a game-changer in a deep rut, locking the wheels to maintain grip where others might’ve faltered. The Rough Terrain Mode (RTM) further impressed on a sandy stretch, directing torque to the wheel with the most grip, keeping me moving smoothly.
The X-Terrain model’s front camera system also proved handy, helping me navigate tight rocky sections.
Off-Road Specs
The MU-X’s off-road specs are impressive: 235mm ground clearance (230mm for LS-M), a 29.2° approach angle, 26.4° departure angle, and 23.1° ramp-over angle. On Mundaring, it cleared most rocks and ruts with ease, though a jagged ledge caused a slight scrape on the underbody—a reminder to add steel bash plates for hardcore trails. Its 800mm wading depth is ready for water crossings, but I’d recommend a snorkel for deeper fords, especially in muddy conditions like those on Mundaring. The stock Bridgestone Dueler HT tyres struggled in loose sand, so I fitted all-terrain tyres before the test, which transformed grip and stability.
With a 3.5-tonne towing capacity (3.0L models) and 605kg payload, the MU-X is perfect for family off-road trips or heavy-duty tasks.
My Mundaring Test Drive: Real-World Performance
Here’s a detailed breakdown of how the MU-X performed on the Mundaring Powerline Trail:
- Steep Inclines: The 3.0L engine and Low-Range mode powered through a 30-degree climb, with torque to spare for loose rocks.
- Rocky Terrain: 235mm clearance handled most obstacles, but a scrape highlighted the need for underbody protection.
- Sandy Stretches: All-terrain tyres and RTM prevented bogging, keeping me moving smoothly.
- Muddy Ruts: The rear diff lock ensured grip in slippery conditions, even with one wheel off the ground.
- Towing: The MU-X easily towed a 1.5-tonne trailer over uneven terrain, ideal for family adventures.
The MU-X proved its off-road credentials, but for extreme conditions, upgrades are key to unlocking its full potential.
Limitations and Elite Tune Solutions
While the MU-X is highly capable, it has limitations for hardcore off-roading:
- Stock Tyres: The highway-terrain tyres lack grip on sand and mud. We recommend all-terrain tyres for better traction.
- Ground Clearance: 235mm is solid but can scrape on jagged rocks. A 2″ lift kit boosts clearance.
- Underbody Protection: Mundaring’s rocks exposed the need for steel bash plates.
- Water Crossings: The 800mm wading depth is good, but a snorkel ensures engine safety in deeper fords.
At Elite Tune, we address these with tailored solutions:
- ECU Remapping: Boosts torque for climbs and towing.
- Suspension Lifts: Improves clearance and handling.
- All-Terrain Tyres: Enhances grip on tough terrains.
- Underbody Protection: Such as steel bash plates.
- Snorkels: Moonlight 4WD or Safari Armax for water and dust protection.
Conclusion: The MU-X Is Suitable for Off-Roading
This Isuzu MU-X off road review confirms it’s not just suitable for off-roading—it’s a standout performer on trails like Mundaring. With a powerful 3.0L engine, advanced 4WD system, and robust specs, it handles steep climbs, rocky terrain, and sandy stretches with ease.
