The 2025 Mercedes-Benz G-Class in India is expected to be offered with powerful engine options, likely including a petrol and potentially a diesel, both incorporating 48V mild-hybrid technology for enhanced efficiency and smoother operation. The primary variant is expected to be the G 500, powered by a 4.0-litre twin-turbocharged V8 petrol engine producing around 422 PS of power and 610 Nm of torque, with the mild-hybrid system adding a temporary boost. A diesel option, such as the G 400d with a 3.0-litre inline-six turbocharged diesel engine producing around 330 PS and 700 Nm, might also be available. Both engines are paired with a smooth 9G-TRONIC automatic transmission. 
The G-Class features a permanent all-wheel-drive system, a low-range transfer case, and three 100% differential locks (center, rear, and front), which are manually engaged and provide its legendary off-road capability. On-road performance is strong for a vehicle of this type, with the V8 petrol offering effortless acceleration, though its boxy shape and weight limit outright speed and agility. Real-world fuel efficiency is low, typical for a powerful, heavy, and aerodynamically challenged SUV.

The interior of the 2025 Mercedes-Benz G-Class offers a striking contrast to its rugged exterior, providing a luxurious and technologically advanced cabin experience. The design blends classic G-Class elements, such as the passenger grab handle on the dashboard and the prominent differential lock buttons, with modern Mercedes-Benz luxury. The dashboard features the widescreen cockpit, integrating the digital instrument cluster and central touchscreen infotainment system. Material quality is exceptionally high, with premium leather upholstery, exquisite wood or carbon fibre trims, and metallic accents throughout.
Seating is for five occupants, with comfortable and supportive seats offering a commanding view of the road. Rear-seat space is good, with ample legroom and headroom for adults. Cargo space is practical, with a boot capacity of around 667 litres, expandable by folding the rear seats. Storage spaces within the cabin are well-integrated. Features like multi-zone automatic climate control, ambient lighting, heated and ventilated seats, and a sunroof enhance the luxurious ambiance.

The exterior design of the 2025 Mercedes-Benz G-Class is instantly recognizable and largely unchanged, maintaining its iconic, boxy, and upright silhouette. It features a prominent grille, round LED headlamps with integrated LED daytime running lights, and exposed door hinges – design cues that pay homage to its heritage. The external spare wheel mounted on the rear door is a signature element.
The body is mounted on a robust ladder-frame chassis, essential for its off-road prowess. Key dimensions include a length of around 4817 mm, a width of 1931 mm (excluding mirrors), and a height of 1969 mm. The wheelbase measures 2890 mm. Ground clearance is a substantial 241 mm, and it boasts impressive approach, departure, and breakover angles, crucial for tackling challenging terrain. The design is functional yet exudes a sense of timeless ruggedness and luxury.

Safety is a key consideration for the 2025 Mercedes-Benz G-Class, built on a robust ladder-frame chassis and featuring a strong body structure. While its design is traditional, it incorporates modern safety technologies. As of early 2025, specific BNCAP or the latest Global NCAP ratings for the G-Class might be pending, but its inherent robustness and safety features provide a high level of occupant protection.
Standard safety equipment is comprehensive and includes multiple airbags, ABS with EBD, Electronic Stability Control (ESC), and Traction Control. A range of advanced driver-assistance systems (ADAS) is available, potentially including active brake assist, blind-spot assist, lane keeping assist, and adaptive cruise control on higher variants or as optional packages. Features like a 360-degree camera system and parking assist are standard, aiding in maneuvering. The combination of a strong structure and advanced electronic aids contributes to a high level of active and passive safety, balancing its rugged nature with modern safety standards.

The 2025 Mercedes-Benz G-Class SUV competes in a very exclusive niche in the ultra-luxury SUV segment in India, primarily against vehicles that offer a blend of luxury and capability, though few match its specific combination of iconic status and extreme off-road prowess. Its primary rivals include the Land Rover Range Rover, which offers unparalleled luxury and strong off-road capability (though less extreme than the G-Class), and potentially high-end variants of the BMW X7 or Mercedes-Benz GLS, which offer luxury and space but are not designed for serious off-roading. The G-Class differentiates itself with its iconic design, legendary off-road hardware (three differential locks), and a unique blend of ruggedness and luxury that is unmatched. Its value proposition lies in its exclusivity, capability, and enduring appeal as an automotive icon.

The 2025 Mercedes-Benz G-Class SUV continues to be a truly unique and desirable vehicle in the Indian market. It successfully maintains its iconic status and legendary off-road capability while incorporating modern luxury, technology, and refined powertrains. It is not a mainstream SUV, but for those who demand a vehicle that can tackle extreme terrain with ease while cocooning occupants in a luxurious and high-tech cabin, the G-Class is in a class of its own.
For buyers in India who seek a vehicle with unparalleled presence, go-anywhere ability, and uncompromising luxury, the 2025 Mercedes-Benz G-Class is the ultimate choice. Its blend of ruggedness and opulence is unmatched. While it comes with a significant price tag and compromises on on-road dynamics and fuel efficiency compared to more road-focused luxury SUVs, the G-Class delivers a unique and highly desirable ownership experience. The G 500 variant offers a strong balance of performance and luxury.
