GWM Tank 300 Diesel Review: Key Buyer Considerations
Is the Diesel Tank 300 Worth Your Investment?
For Australian off-road enthusiasts considering the GWM Tank 300, the new 2.4L turbo diesel variant presents a compelling proposition. After thoroughly analyzing hands-on test footage and specifications, I believe this powertrain addresses critical gaps in the lineup. Diesel engines traditionally offer advantages for serious 4WD owners: superior torque for challenging terrain, extended driving range, and enhanced towing capability. The Tank 300 diesel specifically delivers 135kW and 480Nm through a 9-speed automatic transmission, slotting between the petrol ($47,990+) and hybrid models in both price and performance. What makes this particularly noteworthy is the payload increase to 600kg - a 51% improvement over the petrol version's limiting 397kg capacity. This transforms the vehicle's utility for camping or expedition use, though as we'll explore, it comes with tangible trade-offs.
Detailed Specifications Breakdown
Powertrain and Performance Metrics
The heart of this variant is GWM's 2.4L four-cylinder turbo diesel, also used in Cannon utes but newly adapted for the Tank 300. Comparing the full range clarifies positioning:
| Variant | Power | Torque | Towing | Price (Driveaway) |
|---|---|---|---|---|
| Petrol | 162kW | 380Nm | 2,500kg | From $47,990 |
| Diesel | 135kW | 480Nm | 3,000kg | $47,990-$51,990 |
| Hybrid | 255kW | 648Nm | 2,500kg | Premium priced |
Official fuel economy sits at 7.8L/100km, though initial testing observed approximately 9.5L/100km. This engine configuration maintains the Tank 300's part-time four-wheel-drive system with low-range gearing and locking differentials. The Ultra trim adds a front differential lock, heated/ventilated Nappa seats, massaging driver's seat, and upgraded audio - significant value at $51,990 driveaway.
Practical Changes Beyond the Engine
Critically, the diesel variant brings more than just an alternative powertrain. The suspension calibration differs noticeably from petrol models, likely to accommodate the increased 600kg payload capacity. During testing, this manifested as a firmer ride over urban obstacles like speed bumps. GWM engineers also reinforced the chassis to handle the 3,000kg braked towing capacity - highest in the Tank 300 range. These mechanical changes create a distinct driving character that prioritizes load-bearing capability over outright comfort.
Driving Dynamics Analysis
On-Road Behavior and Limitations
Behind the wheel, the diesel's torque advantage proves immediately valuable. You feel the 480Nm shove when accelerating from low speeds, eliminating the petrol engine's need for higher revs. However, throttle calibration presents a notable challenge. Testers observed a frustrating delay between pedal input and power delivery - a significant issue when merging or overtaking. This isn't uncommon in modern diesels with complex emissions systems, but it's particularly pronounced here. Combined with the stiffer suspension, the driving experience feels less refined than the petrol model which soaks up bumps more effectively. If daily commuting comfort is your priority, this diesel variant may disappoint.
Off-Road Capability Assessment
The Tank 300 platform remains impressively capable off-road thanks to its 224mm ground clearance, live rear axle, and available front/rear diff locks. However, powertrain calibration creates operational challenges:
- The short-travel throttle requires feather-light inputs to avoid jerky progress
- Low-range gearing holds gears excessively (up to 4,000rpm) when ascending inclines
- Torque delivery isn't linear, complicating technical rock-crawling situations
While terrain modes partially mitigate these issues, they don't eliminate the fundamental calibration shortcomings. Having tested multiple 4WD systems, I'd recommend the petrol variant for technical trails unless you specifically need the diesel's payload or towing advantages.
Diesel-Specific Buyer Considerations
Who Should Choose This Variant?
Based on its mechanical profile, the diesel makes most sense for three buyer types:
- Expedition travelers needing the 600kg payload for rooftop tents and gear
- Towing users requiring the 3,000kg capacity for trailers or boats
- Remote area drivers prioritizing fuel range over ride refinement
Critical Compromises to Acknowledge
Prospective buyers must weigh these verified drawbacks:
- Ride quality degrades noticeably versus petrol models
- Throttle lag affects both on-road and off-road driving
- Real-world fuel consumption may exceed claims by 20%
- Payload advantage comes with suspension trade-offs
Final Recommendations and Alternatives
When the Diesel Tank 300 Shines
This variant delivers exceptional value if your use case aligns with its strengths. The combination of locking differentials, increased payload, and segment-leading towing capacity at under $52,000 is unmatched. For remote touring or towing duties, the torque advantage justifies selecting this over the petrol model. GWM's 7-year/unlimited km warranty provides additional peace of mind.
Action Steps Before Purchasing
- Test drive back-to-back with the petrol model on rough roads
- Verify payload needs - choose diesel only if requiring >397kg capacity
- Negotiate using current deals listed on GWM's Australian website
- Review independent testing at Drive.com.au for latest findings
Concluding Thoughts
The diesel Tank 300 fills a strategic gap in GWM's lineup, offering serious 4WD buyers tangible benefits where they matter most: towing and payload. However, this comes at the cost of ride comfort and throttle refinement. In my assessment after reviewing all available data, it's not the default choice - but rather a specialized tool for specific needs. The petrol variant remains better suited for daily driving and technical trails, while the diesel excels when load-carrying or towing demands take priority. Ultimately, your decision should hinge on whether you'll regularly utilize its 600kg payload or 3,000kg towing capacity - if not, the compromises may outweigh the benefits.
