At first glance, this boxy silhouette looks exactly like the military-grade icon that has roamed the earth for 45 years—but is it really a “sensible” way to spend nearly ₹3.5 crore, or just a very expensive piece of nostalgia wrapped in Nappa leather?
Buying a luxury SUV in India today is more confusing than ever. You have the tech-heavy EVs that promise the future, and the screaming V8s that celebrate the past. But then comes the Mercedes-Benz G 450d. It is the return of the “sensible” G-Wagen, a car that aims to prove that diesel isn’t just surviving; in the right package, it’s actually winning.
If you’re planning to buy this car, here’s what you must know: the G 450d isn’t just the “entry-level” G-Class. In many ways, it’s the best G-Class for India. Having spent over 12 years testing everything from the humblest hatchbacks to the most aggressive supercars, I can tell you that the G-Class is the only vehicle that feels like it was carved out of a single block of granite.
But here’s the catch—can a diesel engine truly provide the “G-Factor” without the thunderous roar of an AMG V8? This is where things get interesting. Let’s dive into the Mercedes-Benz G 450d review: Win diesel? and see if this mild-hybrid oil-burner is the ultimate “G” for the Indian road.
The Icon Re-engineered: Quick Overview
The Mercedes-Benz G 450d arrived in India in late 2025 as the successor to the highly popular G 400d. It represents the “W465” generation—a subtle but significant update to the W463 that we’ve known since 2018.
Unlike the flamboyant AMG G 63 or the silent G 580 Electric, the G 450d is built for the long haul. It features a new 3.0-litre inline-six diesel engine paired with a 48V mild-hybrid system. In a market where the Land Rover Defender has been eating into the G-Wagen’s territory, Mercedes has priced this at ₹2.90 Crore (ex-showroom).
It’s expensive, it’s exclusive (only 50 units were in the first batch), and it’s arguably the most capable “daily driver” G-Class ever made.
Exterior Design: The Unchanging Legend
Mercedes-Benz knows better than to mess with the G-Wagen’s design. If they changed the shape, the fans would probably riot. However, for 2026, the G 450d gets some “stealth” updates that only an expert would notice at a traffic light.
The New Details
The front grille now features four horizontal slats instead of the previous three, a design cue it actually shares with the new Electric G. The A-pillars have been slightly rounded and there’s a small “lip” on the roof above the windshield—changes made to improve aerodynamics and reduce the wind noise that used to make long highway trips a bit tiring in older Gs.
The AMG Line Stance
In India, the G 450d comes standard with the AMG Line trim.
- Wheels: You get massive 20-inch AMG multi-spoke alloy wheels finished in gloss black.
- Bumpers: The front and rear bumpers have been slightly redesigned with more “squircle” air intakes.
- The Door Sound: Rest assured, the legendary “rifle-bolt” click of the door locks and the mechanical “thud” of the doors closing are still very much present. If you know, you know.
Interior Design & Comfort: A Digital Fortress
Stepping into a G-Class is an event. There are no “grab handles” to help you in; you hoist yourself up using the steering wheel and plant yourself into what feels like a captain’s chair.
The MBUX Upgrade
The biggest interior news is the transition to the MBUX NTG7 software. The twin 12.3-inch screens are now touch-sensitive (finally!), and the system is lightning-fast.
- Off-Road Cockpit: A new dedicated button on the dash brings up a screen showing your steering angle, tire pressure, and altitude.
- Transparent Bonnet: Using the 360-degree cameras, the screen shows you exactly what is under the front bumper—a lifesaver when you’re navigating a rocky trail in the Aravallis or a tight parking spot in Mumbai.
Luxury and Materials
The cabin is a masterclass in “Old World” luxury meets “New Age” tech. You get Nappa leather upholstery, a 64-color ambient lighting system, and a 760W 18-speaker Burmester sound system with Dolby Atmos. It sounds less like a car and more like a private theater.
But here’s the catch: the G-Class is still a narrow car. While there is plenty of headroom (you could wear a turban or a top hat inside), the shoulder room is a bit tight for three adults in the back. And because of the ladder-frame chassis, the rear floor is high, which means under-thigh support for tall passengers isn’t as good as it is in a GLS or a Range Rover.
Engine Specifications & Performance: The Power of Six
This is the “Win Diesel” part of the story. The G 450d features the OM 656M engine—a 3.0-litre inline-six that is perhaps the finest diesel engine in production today.
The Mild-Hybrid Boost
The engine produces 367 hp and a massive 750 Nm of torque. But wait, there’s more. The 48V Integrated Starter Generator (ISG) provides an additional 20 hp and 200 Nm of “electric shove” at low speeds.
Performance Statistics Table
| Specification | Mercedes-Benz G 450d |
| Engine | 2989 cc, Inline-6 Turbo Diesel |
| Max Power | 367 hp + 20 hp (Hybrid) |
| Max Torque | 750 Nm + 200 Nm (Hybrid) |
| Transmission | 9G-TRONIC Automatic |
| 0-100 km/h | 5.8 Seconds |
| Top Speed | 210 km/h |
| Drivetrain | Permanent AWD with 3 Diff Locks |
On the road, the G 450d is surprisingly quick. In Sport mode, it lunges forward with a relentless surge of torque that makes its 2.5-tonne weight feel non-existent. The hybrid system fills in the gaps before the turbo fully spools up, making the power delivery feel like one long, endless wave. It’s significantly faster than the old G 400d and feels much more effortless than a Defender diesel.
Mileage and Fuel Efficiency: The Practical Side of 3 Crores
Usually, “G-Class” and “Mileage” don’t belong in the same sentence. But the G 450d is the exception.
- Claimed Mileage: ~11.23 kmpl
- Real-World City: Expect 7-8 kmpl in heavy urban traffic.
- Real-World Highway: You can comfortably achieve 10-11 kmpl if you cruise at 100 km/h.
With a massive 100-litre fuel tank, you are looking at a highway range of nearly 900-1000 km. In a country like India, where high-quality petrol for an AMG can be hard to find in remote areas, the diesel G 450d is the true king of the road trip.
Mercedes-Benz G 450d Review: Win Diesel? (PART 2)
In Part 1, we established that the G 450d isn’t just a placeholder until the Electric G arrives—it’s a 750 Nm statement that diesel still has a very loud, very torque-heavy voice in the luxury world. We’ve seen the “Hammerhead” inspired grille updates and the 5.8-second sprint that makes this 2.5-tonne box move like a sports car.
But as any veteran G-Wagen owner will tell you, the real magic isn’t in the speed; it’s in the way it handles the world outside the showroom. If you’re planning to buy this car, here’s what you must know: the 2026 G 450d has finally learned some “road manners” without losing its “mountain-climbing” soul. Let’s dive into the tech, the safety, and the cold hard math of the ₹3 Crore club.
Features and Technology: The Smart Merc
Mercedes has finally dragged the G-Class into the modern digital era with the MBUX NTG7 system. It’s no longer just a rugged truck with a screen; it’s a high-definition experience.
- The Transparent Hood: This is a small insight only an expert would appreciate—when you engage “Off-Road” mode, the 360-degree cameras stitch together a live feed of what is directly under the front of the car. On a rocky trail in the Aravallis, it’s like having X-ray vision.
- Burmester 3D Surround Sound: The 18-speaker, 760W system with Dolby Atmos is a masterclass in acoustics. Because the 2026 model features significantly improved sound insulation in the A-pillars, you can actually hear the subtle notes of a violin even while the inline-six is working hard.
- Augmented Reality Navigation: The MBUX system overlays navigation arrows directly onto a live video feed of the road ahead. In a confusing five-way intersection in Bangalore or Delhi, it’s a godsend.
But here’s the catch: while the dual 12.3-inch screens are now touch-sensitive, the trackpad on the center console has been removed. You’ll find yourself leaning forward to touch the screen more than you’d like, which can be a bit of a stretch in such a high-seated vehicle.
Safety Features: The 9-Airbag Shield
Safety in a G-Class is inherent in its “vault-like” build, but for 2026, Mercedes has added a comprehensive electronic safety net.
- Standard Safety: The G 450d comes with 9 airbags, including side-impact airbags for the rear passengers and a driver’s knee airbag.
- Level 2 ADAS: You get Active Brake Assist, Lane Keeping Assist, and the Active Distance Assist DISTRONIC, which is essentially adaptive cruise control that can bring the car to a full stop in traffic and restart it—a blessing for the daily urban crawl.
- The Structure: It still sits on a heavy-duty ladder-frame chassis, which is essentially the gold standard for durability. It doesn’t just meet safety standards; it physically dominates them.
Ride Quality: The Gentle Giant
This is where the G 450d truly “wins.” The old G-Wagens were famous for being bouncy—they felt like they were dancing on top of the road rather than being part of it.
The 2026 model features Adaptive Adjustable Damping as standard. This system monitors the road and adjusts the shocks in milliseconds.
- On-Road: In “Comfort” mode, it’s surprisingly pliant. It no longer “shimmies” over bridge joints.
- Off-Road: With 241 mm of ground clearance and a 700 mm water-wading depth, it remains virtually unstoppable. The three mechanical differential locks are still the heart of the beast—nothing else in the luxury world (except maybe a Wrangler) offers this level of mechanical purity.
Price and Variants: The Reality Check
In India, the G 450d is sold in a single, highly-specced AMG Line variant. While it’s the “cheapest” G-Class, the word “cheap” is purely relative.
| Variant | Engine | Price (Ex-Showroom) | Est. On-Road (Mumbai) |
| Mercedes G 450d | 3.0L Diesel Hybrid | ₹ 2.90 Crore | ₹ 3.49 Crore |
| Mercedes G 580 | Quad-Motor Electric | ₹ 3.10 Crore | ₹ 3.25 Crore |
| Mercedes-AMG G 63 | 4.0L V8 Petrol | ₹ 3.85 Crore | ₹ 4.62 Crore |
Competitor Comparison: G-Class vs. The World
| Feature | Mercedes G 450d | Land Rover Defender 110 (D300) |
| Engine | 3.0L Inline-6 Diesel | 3.0L Inline-6 Diesel |
| Power/Torque | 367 hp / 750 Nm | 300 hp / 650 Nm |
| 0-100 km/h | 5.8 Seconds | 7.0 Seconds |
| Chassis | Ladder Frame | Monocoque |
| Price (Ex-S) | ₹ 2.90 Crore | ₹ 1.25 Crore (approx) |
The Defender is technically a better “handling” car and significantly more affordable, but it lacks the “Handmade in Graz” exclusivity and the bank-vault presence of the G.
Pros and Cons: The Unfiltered Truth
Pros:
- The Engine: The 3.0L inline-six is a masterpiece of torque and refinement.
- Exclusivity: Limited units and that iconic silhouette make you the “Alpha” on any road.
- Off-Road King: Triple diff locks and a 700mm wading depth are legendary.
- Tech Upgrade: MBUX NTG7 finally makes the cabin feel modern.
- Range: A 1,000 km highway range is something no EV can match.
Cons:
- The Price: At ₹3.5 Crore on-road, the “value for money” conversation ended long ago.
- Rear Space: Shoulder room and under-thigh support are still tight for a car this large.
- Wind Noise: Better than before, but that upright windshield still catches a lot of air above 120 km/h.
- Maneuverability: The 6.6-meter turning radius makes U-turns in city traffic a multi-point affair.
Who should buy this vehicle?
You should buy the Mercedes-Benz G 450d if you are a connoisseur of mechanical engineering. It’s for the person who wants the ultimate “Go-Anywhere” tool but needs it to be refined enough to park at the Taj for dinner. If you value range, reliability, and that unmistakable “door-click” over the silent hum of an EV, the G 450d is your winning ticket.
Who should avoid it?
Avoid the G 450d if you are looking for a family-friendly luxury SUV. For ₹3.5 Crore, a Mercedes GLS or a Range Rover provides significantly more comfort, space, and a softer ride for your passengers. The G-Class is a driver’s ego trip; your rear passengers might not always share your enthusiasm.
Expert Verdict: Win Diesel?
The Mercedes-Benz G 450d review: Win diesel? leads us to one inescapable conclusion: for the Indian context, this is the “Goldilocks” G-Wagen.
It has more torque than you’ll ever need, a range that spans states, and a presence that stops traffic. It isn’t as loud as the AMG, and it isn’t as “clean” as the Electric G, but it is the most honest version of the icon. In a world of digital shortcuts, the G 450d remains a mechanical masterpiece. Yes, diesel wins this round.
FAQs: High-Quality Questions Answered
Q1: Is the G 450d better for India than the AMG G 63?
For daily driving and long-distance touring, yes. The G 450d has better fuel range, a slightly softer suspension, and more usable low-end torque. The G 63 is for theater and track days; the 450d is for the real world.
Q2: Does it require AdBlue?
Yes, like all modern BS6 Phase 2 diesels, it requires AdBlue to stay Euro 6e compliant. The tank is large enough to usually last between regular service intervals.
Q3: How is the maintenance cost?
Being a CBU (Completely Built Unit) Mercedes, expect annual services to cost between ₹80,000 to ₹1.2 Lakh. Parts like the 20-inch tires and brake pads are also premium-priced.
Q4: Can it handle extreme off-roading like the Rubicon?
Absolutely. With three independent differential locks, it is more capable than 99% of the SUVs on the planet. Its only limitation is the 20-inch wheels; for serious off-roading, 18-inch rims with All-Terrain tires are recommended.
Q5: Is there a long waiting period?
Yes. Mercedes-Benz India typically brings these in small batches (the first was just 50 units). Depending on the city, the wait can range from 6 to 12 months.
