🚗

The Mercedes-Benz GLS specifications rest on two 3.0 litre inline-six engines, both with 4MATIC and mild-hybrid help. A nine-speed automatic is standard across the range. Seven seats define the body and its purpose. The two engines are closely matched on paper. Only the fuel and the torque really separate them. Weight is high, as expected for this size.

The petrol 450 makes 375 bhp and revs smoothly. The diesel 450d produces 362 bhp but a far larger 750 Nm of torque. That torque suits moving this heavy seven-seater with ease. Both drive all four wheels through 4MATIC.

Both engines carry the same ARAI rating of 12 kmpl, modest for a large inline-six SUV. The diesel usually feels more frugal on long highway runs. The car's weight keeps real figures lower. Read the GLS fuel figures in full to compare.

At 5209 mm long on a 3135 mm wheelbase, it is a genuinely big SUV. The tank holds 90 litres and there are seven seats across three rows. Width is 2157 mm and height 1823 mm. Ground clearance is 200 mm for rough roads. The kerb weight is high, given the size and seven seats. The petrol is 2999 cc and the diesel 2989 cc.

Each engine now comes in two styling levels, AMG Line and Night Edition. The Night Edition adds ₹3.00 Lakh with the same engine. The petrol 450 4MATIC AMG Line opens the range at ₹137.50 Lakh. Follow the GLS price ladder from base to Night Edition to place your budget.

Mercedes-Benz GLS power and torque explained

The GLS comes with two engines, and both are 3.0 litre inline six units with a 48 volt mild hybrid. The 450 4MATIC is the petrol and the 450d 4MATIC is the diesel. Every version drives all four wheels through a 9 speed automatic.

The two feel different in character. The diesel is the low down worker, shoving this heavy seven seater along with barely any effort. The petrol prefers to spin higher before it gives you its best.

How to read this chart. Torque is the push you feel when you accelerate, and it peaks low on the rev range. Power is how hard the engine keeps pulling as it revs higher, and it peaks further up. The two dots mark those peaks. The shaded strip between them is the flexibility band: a wider band pulls easily across more revs and feels relaxed in traffic, while a narrower band asks you to rev the engine more to get its best. Use the buttons above to compare this car's engines.

Peak figures come from the 3.0L Inline-6 Turbo Diesel Mild Hybrid spec sheet. The line between the two peaks is not a measured dyno curve.

The 450d diesel makes its full 750 Nm of torque low down at 1350 rpm, then keeps pulling to peak power of 367 PS at 4000 rpm. Its strong pull stretches across a wide 2650 rpm band. Press the pedal and it surges forward at once, even with seven seats full and luggage aboard. It stays calm and quiet in town, and cruises the highway with plenty in reserve. Choose the diesel if you drive long distances or often carry a full car, and compare the six GLS trims to see which ones use it.

The 450 petrol makes 500 Nm of torque at 1600 rpm, so it still moves off cleanly without much effort. But its real reward comes higher up, with 381 PS arriving at 5800 rpm. That power spreads over a long 4200 rpm band, so it keeps building the more you rev it. This is the smoother, keener engine for quick overtakes and flowing open roads. Pick the petrol if most of your driving is in the city or you prefer a quieter, higher revving feel. See everything else on the GLS before you decide.
