First impression and positioning
The GLS is Mercedes’ flagship SUV. It is large and stately. From the road it reads as a luxury vehicle first and an off-roader second. Mercedes positions it as the S-Class of SUVs. That means the GLS prioritises comfort, technology and a quiet cabin over aggressive driving dynamics. In India the GLS sits near the top of the luxury ladder and competes with other full-size rivals for buyers who need space, presence and high levels of refinement. Recent listings show GLS prices in India start in the low crore range and move into the higher crores for AMG or Maybach derivatives. CarDekho+1
Exterior design and road presence
The GLS looks dignified and understated rather than loud. The front gets a wide grille with a prominent Mercedes star and slim headlamps that give the face a composed expression. The long wheelbase means large doors and easy access for second-row passengers. Large alloy wheels and a tall stance add road presence that suits chauffeur driven or owner-driven use. The overall proportions favour comfort and space rather than sporty lines, which is exactly what this car promises to deliver inside.
Interior layout and passenger comfort
Step inside and the scale becomes obvious. The GLS offers a roomy, highly finished cabin that focuses on passenger comfort. Materials are soft and well stitched, and there are wood, metal or polished trim options depending on the specification. The front seats are highly adjustable and in top trims they include ventilation, heating and massage functions. The second row can be fitted with individual captain seats for extra comfort, or with a bench for maximum seating capacity. The third row is usable for adults on shorter trips and comfortable for children on longer journeys. Practical storage, multiple cup holders, and lots of USB/charging points make the GLS easy to live with on family trips.
Mercedes’ widescreen MBUX digital cockpit defines the interior experience. The large central touchscreen and the instrument cluster form a broad glass surface that handles navigation, media, vehicle settings and connected services. Voice control responds to natural commands and makes day to day tasks easier for occupants. The cabin is very quiet at speed, which helps long trips feel relaxed and hotel-like.

Engines, drivetrain and performance
The GLS offers a range of powertrains globally and in India you will typically see powerful inline-6 petrol and diesel options, plus higher-performance V8 and AMG variants in certain models. The GLS 450 and GLS 450d are commonly offered; these deliver strong midrange torque for smooth overtakes and effortless highway cruising. AMG and Maybach GLS derivatives push power much higher for buyers who want outright performance from a big SUV. Gearboxes are advanced multi-ratio automatics that shift quietly and aid fuel economy during steady cruising. For buyers who tow or regularly carry heavy loads, the diesel variants provide good torque and relaxed long-distance performance. Official Mercedes material and dealer listings confirm the GLS’ multiple engine options and high power figures for premium trims. Mercedes-Benz+1
Ride, suspension and handling on Indian roads
The GLS uses air suspension with adaptive damping in most trims. This system smooths out potholes and broken surfaces and keeps the cabin isolated from road harshness. In town the GLS feels controlled and composed; on the highway it is planted and secure. The steering is weighted more toward stability than quick responses — the GLS aims for a secure, calm driving feel rather than sporty feedback. Ground clearance and a robust chassis also allow light off-road use or rough rural stretches, but this is not a hardcore off-roader. For the typical Indian large-SUV buyer who spends time on highways and city sprawl, the GLS offers a serene and confidence-inspiring ride.
Features and technology that matter
Mercedes packs the GLS with technology that enhances comfort and safety. Expect a large MBUX widescreen display, multi-zone climate control, premium sound systems, panoramic sunroof and multiple seating adjustment options. Rear passengers can get individual climate zones, entertainment screens in some trims, and power seats with memory. The GLS also offers advanced driver assistance features to reduce stress on long journeys. These include adaptive cruise control, lane keep assist, automatic emergency braking and active blind-spot monitoring. In India, Mercedes equips higher GLS variants with comprehensive ADAS technology that meaningfully reduces driver fatigue on long highway runs. Mercedes-Benz+1
Safety and driver assistance
Safety is a core part of the GLS proposition. Multiple airbags, electronic stability systems, traction control, hill start/descend control and strong crash structure are standard. The ADAS suite available in higher trims includes adaptive cruise control, lane keeping, automatic emergency braking with pedestrian detection, and parking aids including 360-degree cameras. These systems work together to lower the likelihood of incidents and to assist during long distance driving. For buyers who prioritise active safety technology and high crash protection in a large family SUV, the GLS offers a modern package.
Practicality, luggage space and daily use
The GLS is practical for family life. With the third row up you get usable luggage room for short trips. Folding the third row increases boot capacity a lot, and folding the second row creates a large, flat cargo floor for moving bigger items. The GLS is heavy, so city parking and tight lanes require attention, but generous running boards and wide doors make entry and exit easy. Large fuel tank capacity and efficient diesel options help reduce stops on long routes, making the GLS a good fit for long-distance travel in India.
Running costs and fuel economy
Full-size luxury SUVs are expensive to run compared with compact cars. The GLS is no exception. Diesel variants tend to return the best real-world economy for this class, while petrol V8s and AMG models will sip more fuel, especially under spirited driving. Service, tyres and insurance costs are also higher than mainstream vehicles. Mercedes offers service packages and extended warranties which can help manage long-term ownership costs. Reported and official mileage numbers for GLS models in India generally fall in the low teens km/l depending on variant and mix of city/highway driving. Expect diesel GLS variants to perform better on the highway than petrol V8s in terms of economy. CarWale+1
Price and variants in India
In India the GLS is a premium purchase. Recent public price listings show ex-showroom GLS prices starting in the low crore range and moving higher for AMG Line trims and special-edition derivatives. Actual on-road prices vary by city, options and taxes. Mercedes sometimes updates pricing seasonally; buyers should check the latest dealer quote and available official offers. The GLS also appears in high-end Maybach or AMG versions at significantly higher price points for buyers seeking ultimate exclusivity or performance. CarDekho+1
How the GLS compares with rivals
The GLS competes with other full-size luxury SUVs such as the BMW X7 and Audi Q7, though each brand has its focus. The GLS places a higher weight on rear-seat comfort, interior technology and a tranquil cabin. The BMW X7 leans a touch more toward sportier handling, while the Audi Q7 is often seen as a balanced, tech-heavy alternative. Buyers should pick the GLS if their priority is interior luxury, rear-seat comfort and the latest Mercedes connectivity and ADAS features rather than maximum driving sharpness.
Ownership tips for Indian buyers
If you plan to buy a GLS for India, consider these points. Choose diesel if you mostly do highway miles with heavy loads or towing. Opt for higher ADAS and rear comfort packages if you use the car with a chauffeur or frequently carry family. Buy a service package or extended warranty to smooth maintenance costs over time. Check local dealer stock for optional packs — Mercedes often offers factory fitted options that are cheaper than post-sale retrofits. Finally, ensure parking space is adequate; the GLS is a large vehicle and benefits from a covered, secure parking spot.
Frequently asked questions
Is the Mercedes GLS a true seven-seater for adults?
Yes. The GLS comfortably seats seven. The second row is especially generous. The third row is usable for adults on short to medium trips and comfortable for children on long rides.
Which engine should I pick for India — petrol or diesel?
Choose diesel if you do long highway miles and require lower running costs. Select petrol or AMG options if you want higher performance and quicker acceleration and accept higher fuel consumption.
How is GLS maintenance in India?
Maintenance for a GLS is costlier than a mainstream car. Mercedes offers scheduled service packs and extended warranties which help reduce surprises. Service centres are available in major cities.
Does the GLS come with ADAS?
Yes. Higher GLS variants include a broad ADAS suite: adaptive cruise control, lane keep assist, automatic emergency braking, blind spot monitoring and more.

Conclusion – who should buy the GLS
Buy the Mercedes GLS if you want the highest levels of cabin comfort, rear-seat luxury and modern Mercedes technology in a full-size SUV. It is ideal for large families, owner-drivers who value a quiet, refined cabin, and chauffeur-driven use. The GLS delivers smooth highway cruising, comprehensive safety tech and an S-Class-like interior experience in SUV form. If your primary needs are tight-city driving or the lowest possible running costs, a smaller luxury SUV might be a better fit. For buyers who place value on space, tech and executive comfort, the GLS remains a very compelling choice.
