Mercedes calls the GLS the S Class of SUVs, and the third generation model that arrived in India in 2020 does a good job of living up to that name. It is huge, calm, ultra luxurious and surprisingly quick. This 2020 Mercedes Benz GLS review covers the price, engines, interior, space, ride and what it is like to live with in India.
Quick verdict
The 2020 GLS is one of the most comfortable and luxurious seven seat SUVs you can buy in India. It is quiet, spacious and loaded with technology. It is also big, thirsty and expensive to run, and the third row is more useful for kids than tall adults. If you want the ultimate chauffeur or family SUV, it is hard to beat.
2020 Mercedes Benz GLS India launch and price
Mercedes Benz India launched the third generation GLS on June 17, 2020, with an introductory price of Rs 99.90 lakh ex showroom for both variants. The launch took place digitally from the company’s Chakan facility near Pune. The GLS arrived in a difficult year, but it quickly became a flagship for the brand. Over the ten years before this generation, Mercedes sold more than 6,700 units of the GLS and its predecessor, the GL.
On road prices were far higher because of registration, insurance and taxes, and current listings for a used or later model can differ a lot, so always check a dealer quote.
Why is the 2020 Mercedes Benz GLS so popular?
A few clear reasons explain it:
- Space and presence: It is the largest SUV in Mercedes’ lineup and genuinely seats seven in comfort.
- Luxury: The cabin feels like a lounge, with massaging seats, ambient lighting and top end materials.
- Technology: The latest MBUX system, twin screens and rear entertainment make it feel modern.
- Comfort: Air suspension gives a smooth ride on rough Indian roads.
- Status: The three pointed star on a big SUV is a very strong badge.
2020 Mercedes Benz GLS variants and specs
India got two variants, both with 4Matic all wheel drive and a 9 speed automatic.
| GLS 400d 4Matic | GLS 450 4Matic | |
|---|---|---|
| Engine | 3.0 litre inline six diesel | 3.0 litre inline six petrol with 48 volt mild hybrid |
| Power | About 330 hp | About 367 hp, plus up to 22 hp from EQ Boost |
| Torque | 700 Nm | 500 Nm, plus up to 250 Nm from EQ Boost |
| 0 to 100 km/h | About 6.3 sec | About 6.2 sec |
| Launch price | Rs 99.90 lakh | Rs 99.90 lakh |
Diesel or petrol?
The GLS 400d has huge torque, which makes it effortless in traffic and on the highway, and it is the more efficient choice. It was the mainstay of the range in India. The GLS 450 is smoother and quieter, with a refined inline six and the extra EQ Boost for short bursts. If you cover long distances, choose the diesel. If you want maximum smoothness and mostly drive in the city, the petrol is a great choice.
Size and dimensions
The 2020 GLS is bigger than its predecessor, at about 77 mm longer and 22 mm wider, with a wheelbase that is 60 mm longer at 3,135 mm. The extra wheelbase gives about 87 mm more legroom for the second row, which is where this generation really improved.
Driving impressions
For a vehicle weighing more than two tonnes, the GLS moves with surprising ease. Both engines are strong, and the 9 speed automatic shifts smoothly. The steering is light and accurate, and the car feels stable at speed. Airmatic air suspension lets you raise or lower the body by about 60 mm, which helps with entry and exit, high speed stability and clearing bad roads.
Because of its size, city driving needs care. A 360 degree camera and parking sensors make tight spots easier. If you want a luxury SUV that feels more driver focused, the Porsche Cayenne is a sportier alternative.
Interior, space and features
The cabin is where the GLS shines.
- Screens: Twin 12.3 inch displays for the instruments and infotainment, running the MBUX system with voice and gesture control.
- Seats: Powered, ventilated and massaging seats in the first two rows, with memory settings.
- Second row: Adjustable fore and aft, with generous legroom, and a six seat layout with captain’s chairs was offered.
- Third row: An easy entry system and power folding make access simple, though headroom is limited for tall adults.
- Cargo: Up to about 2,400 litres with the second and third rows folded, using a button in the boot.
- Comfort features: Five zone climate control, a panoramic sunroof, 64 colour ambient lighting, wireless charging, 11 USB ports and rear seat entertainment screens.
Safety
The GLS has nine airbags, blind spot assist, active brake assist, a 360 degree camera and hill descent control. These features add to the confidence of a vehicle this large.
Rivals
The main rival is the BMW X7, which is the GLS’s direct competitor in the full size luxury SUV class. The X7 offers a sportier drive and bold styling, while the GLS focuses on comfort and refinement. Other seven seat luxury SUVs such as the Audi Q7 and Volvo XC90 are smaller and cheaper. If you do not need seven seats and prefer a sportier, coupe style SUV, the BMW X4 is another option.
Running costs
Expect high running costs. The GLS is heavy, fuel economy is modest, and tires, brakes and servicing are expensive. Mercedes has offered service packages that help spread the cost, with plans starting at about Rs 82,100 for the GLS 450 for two years at launch.
Used buyer checklist
- Check service records at authorized Mercedes Benz centers.
- Test the air suspension for smooth operation and no warning messages.
- Verify all screens, MBUX features and the 360 degree camera.
- Check the third row folding mechanisms and the tailgate.
- Look at tire wear, as large 21 inch tires are expensive.
- Confirm any remaining warranty or service package and check for recalls.
