2006 – 2021 Refined.
Capable.
Final.
The Gen 4 was the ultimate expression of the Pajero — 140 kW / 441 Nm from the 3.2 Di-D, Super Select II 4WD, seven airbags, carbon-fibre driveshaft. A 15-year production run that ended in 2021. The most accomplished Pajero ever made, and now the best-value used 4×4 in its class.
The Apex Predator — Refined Over 15 Years
When Mitsubishi launched the Gen 4 Pajero in 2006, the brief was clear: take everything the Gen 3 achieved and make it definitively better. More power, more refinement, more safety, more technology — without compromising the off-road capability that defined the nameplate.
They delivered. The upgraded 3.2 Di-D diesel now produced 140 kW and 441 Nm — more torque than any previous Pajero engine. The Super Select II 4WD system gained electronic terrain response modes. Seven SRS airbags became standard. A carbon-fibre driveshaft reduced unsprung weight. Active stability control arrived.
But the Gen 4’s real story is its production longevity. Launched in 2006 and discontinued in 2021, the Gen 4 outlasted its planned successors and became the definitive statement of what Mitsubishi’s engineers could achieve with the Pajero platform. When production ended, it was not because the Gen 4 had become obsolete — it was because the global market had moved toward SUVs, and Mitsubishi’s resources followed it.
The 3.2 Di-D — 140 kW Engine Guide
The Gen 4’s 3.2L Di-D is the best diesel engine ever fitted to a production Pajero. Common-rail direct injection delivers exceptional fuel atomisation and combustion efficiency, producing 441 Nm of torque from 2,000 rpm — more low-end grunt than the V8 rivals of its era. The engine’s architecture is fundamentally shared with the Gen 3’s 4M41 but remapped, with updated turbocharger geometry and intercooler calibration. It is chain-driven (no cambelt to replace) but the top timing chain guide remains the key inspection item at high mileage. Properly serviced, this engine is capable of 400,000+ km without major work.
| Code | Engine | Power | Torque | Notes | Verdict |
|---|---|---|---|---|---|
| 4M41 | 3.2L Di-D Common-Rail Diesel | 140 kW | 441 Nm | The one and only diesel. Chain-driven. Check timing chain guide at 120k km. EGR valve carbon build-up is common on urban-use vehicles. Avoid DPF models (post-2011 in some markets) where possible in SA. | Only Choice |
| 6G75 | 3.8L V6 MIVEC Petrol | 184 kW | 329 Nm | Smooth and powerful but 14–18 L/100km is prohibitive for bush use. Better suited to highway driving. Not the recommended choice for South African conditions — stick to the diesel. | Highway Option |
The Gen 4 3.2 Di-D EGR (Exhaust Gas Recirculation) valve is known to accumulate carbon deposits — particularly on vehicles used predominantly in stop-start urban driving. Symptoms: rough idle at cold start, occasional hesitation, slight power reduction. A clean costs R600–R900; many SA owners fit an EGR blanking plate (R300–R600 plus labour) as a permanent solution. This is a popular and recommended modification for Pajeros used in SA conditions.

Known Issues & What to Inspect
What to Pay
The Gen 4 offers the best value-per-capability ratio of any Pajero in the SA used market. A R250,000 Gen 4 outperforms alternatives costing R500,000+ new.
If you had to choose one Pajero for everything — family road trips, Kgalagadi adventures, weekend trail days and daily commuting — the Gen 4 LWB 3.2 Di-D is the answer. It does everything at a level no previous Pajero could match: safe, powerful, economical, capable and comfortable. A well-maintained 2012–2015 facelifted example is arguably one of the best used 4×4 purchases available in South Africa at any price point. The 140 kW / 441 Nm diesel will still be impressive when everything around it has changed. Buy one, service it properly, and drive it for another 150,000 km.
