The icon gets a diesel heart — and it is the version India has been waiting for.
There are very few automobiles in the world that carry the weight of their own mythology. The Mercedes-Benz G-Class is one of them. Born as a military off-roader in 1979, it has since evolved into one of the most recognisable luxury SUVs on the planet — equal parts brute and bespoke. And now, with the G450d AMG Line priced at Rs. 2.90 crore (ex-showroom), Mercedes-Benz India has finally given this legend a powertrain that aligns with Indian sensibilities: a mighty diesel engine.
The Wait Is Over — Diesel Is Back
Mercedes-Benz had briefly pulled the diesel G-Class out of India after discontinuing the G400d. It left a noticeable gap in the lineup, particularly for buyers who found the AMG G63 too extreme and the G580 EQ too experimental. The G450d steps into that void with quiet confidence. It now completes a powertrain trifecta — petrol (AMG G63), electric (G580 EQ), and diesel (G450d) — making the G-Class the only ultra-luxury SUV in India available across all three energy formats. The first batch was deliberately limited to just 50 units, a move that ensures exclusivity remains part of the deal.
“G Stays the G” — Design That Refuses to Apologise
There is a philosophy inside Mercedes-Benz called “G stays the G,” and it is not a marketing line — it is a structural commitment. The G450d AMG Line wears the same boxy, upright silhouette that designers have protected for over four decades. The exposed door hinges, the flat windshield, the round headlamps — none of that has changed, and none of it should. The AMG Line treatment adds aggression through visual upgrades: a sporty AMG bodystyling kit, 20-inch AMG light-alloy wheels, and a multifunction sports steering wheel wrapped in Nappa leather. It looks like a vehicle that was designed once, got it right, and never needed a revision.
The Engine: 750 Nm of Diesel Drama
Under that upright hood sits a 3.0-litre inline-six diesel engine — the OM 656M — displacing 2,989cc and producing 270 kW (367 HP), further boosted by a 48V mild-hybrid system that delivers an additional 15 kW (20 HP) on demand. The number that defines this car, however, is 750 Nm of torque — available in a thick, relentless surge that simply commands the G-Class’s massive body-on-frame structure to move. Power routes through a 9-speed automatic gearbox to all four wheels, with three locking differentials managing the terrain beneath. Mercedes claims a 0-100 km/h sprint in 5.8 seconds, and even in real-world testing the car recorded a 6.79-second run — extraordinary for a 2.5-tonne box on wheels.
The G450d is a direct upgrade over its predecessor, the G400d. It gains 37 HP and 50 Nm of torque over that car, and the difference is noticeable the moment you press the accelerator. Switch it into Sport mode, and throttle response sharpens, the steering gains weight, and the G450d transforms into something genuinely addictive — fast, loud in the right way, and deeply satisfying. Yet in city traffic, it retreats into civility, offering a refined, effortless cruise entirely in keeping with its luxury positioning.
Inside: A Box That Does Not Feel Like One
Step inside and the G450d’s interior reconciles its military origins with modern opulence in a way no other vehicle quite manages. The cabin features two individual bucket seats upfront — squishy, wide, and supremely comfortable — flanked by a pair of integrated 12.3-inch displays running Mercedes’s latest MBUX infotainment system. The Burmester Dolby Atmos sound system turns the cabin into a premium listening room, further insulating occupants from the rugged machine they are sitting in. The boot offers 640 litres of space, and the fuel tank holds 100 litres — both numbers that remind you this vehicle was engineered to go far and carry a lot while doing it.

Why This One Makes Sense for India
India’s love for diesel SUVs is not casual — it is rooted in the practical reality of long distances, varying road quality, and the emotional satisfaction of torque-rich performance at city speeds. The G450d addresses all of that. The 750 Nm engine handles both the groomed avenues of South Delhi and the broken highways of a weekend drive with the same unruffled authority. The 100-litre tank means fewer fuel stops, and the diesel’s efficiency over a petrol engine of similar output makes running costs meaningfully lower across tens of thousands of kilometres. The AMG G63 is an event. The G580 is a statement about the future. The G450d is a daily driver that happens to be a legend.
Final Verdict
The Mercedes-Benz G450d AMG Line is not trying to be a different car — it is the G-Class, exactly as it has always been, but now tuned for a buyer who drives daily, thinks practically, and still refuses to compromise on presence. The diesel powertrain does not dilute the G-Class experience; it deepens it. At Rs. 2.90 crore, it slots in as the most rational entry point into the G-Class world, and for India, that is a sentence that very few cars can claim to earn.
