Mercedes Maybach GLS 600 specs: two cars, one name

Peak power sits at 6000–6500 rpm on the first car and 6000-6500 on the restyling. Torque is 730 Nm from 2500–5000 rpm, then 2500-5000. Specific output is 558 / 3.982 ≈ 140.1 hp per litre before the restyling and 557 / 3.982 ≈ 139.9 hp per litre after. The restyling is 1 hp and 1 kW down; torque, capacity, and cylinder count do not move.

Peak power sits at 6000–6500 rpm on the first car and 6000-6500 on the restyling. Torque is 730 Nm from 2500–5000 rpm, then 2500-5000.

The restyling is 1 hp and 1 kW down; torque, capacity, and cylinder count do not move.

If the search is “Mercedes-Maybach GLS hp” or “GLS 600 horsepower,” the honest answer is 558 or 557, not a round 600. The badge is larger than the measured peak.

Mercedes Maybach GLS 600: which generation changed what

The catalogue lists 2 generation records, but they are one generation plus a restyling, not two separate generations.

1 generation (2019-01-01 to 2023-03-31). One body: SUV 5-doors. One version: GLS600 4.0 AT EQ Boost 4Matic, 558 hp / 410 kW, 730 Nm, 3982 cc. Mixed consumption 12, CO2 273, 0–100 4.9 s, top speed 250. City and highway consumption are not measured.

1 generation, restyling (from 2023-04-01, no end date). Same body, same version name. Output 557 hp / 409 kW, torque still 730 Nm, capacity still 3982 cc. Mixed consumption 14.1, CO2 320, 0–100 4.2 s, top speed still 250. City and highway consumption remain not measured. Ground clearance remains not measured.

What the restyling changed, in arithmetic only:

The later car is not a more powerful car. It is a quicker-to-100 car that uses more fuel and emits more CO2 on the mixed figure we have.

Mercedes Maybach GLS engine: what the numbers actually buy

The engine is the same catalogue object both times: 3982 cc Gasoline 8-cylinder V-shaped Turbo with Direct injection (direct), Front, longitudinal, compression 10.5, 83 × 92. There are no other engine options in this model’s data. Searches for “Mercedes Benz GLS engine options,” “GLS 450,” or a Maybach GLS sedan do not map onto this file: those bodies and engines are not listed here.

Oil grade and service volumes are not measured. Engine size in litres from the given cc is 3982 / 1000 = 3.982. That is the only displacement on the Maybach GLS in this set.

Torque density is 730 / 3.982 ≈ 183.3 Nm per litre on both cars. Because torque and capacity are identical, the restyling does not buy more pull at the flywheel on paper. The 0.7 s shorter 0–100 run is the only performance gain that shows up in the table.

Mercedes Maybach GLS performance, mpg, and economy

GLS600 4.0 AT EQ Boost 4Matic (558 hp, 2019–2023): 0–100 4.9 s, top speed 250, mixed 12, city not measured, highway not measured, CO2 273, Euro 6, tank 90.

GLS600 4.0 AT EQ Boost 4Matic (557 hp, from 2023-04-01): 0–100 4.2 s, top speed 250, mixed 14.1, city not measured, highway not measured, CO2 320, Euro 6, tank 90.

Mixed consumption rose by 2.1, which is 2.1 / 12 ≈ 17.5% more on the later mixed figure. Range on a 90 litre tank using only the mixed number: 90 / 12 = 7.5 tankfuls per 90 litres of distance-units on the first car versus 90 / 14.1 ≈ 6.38 on the restyling — about 15% less distance per tank if mixed is the only consumption you trust. City and highway remain not measured, so a “mpg” claim split by cycle cannot be made.

Top speed does not reward the restyling: both are 250. The speed limiter, if that is what the number represents, is the same.

The faster sprint on the later car is 4.9 − 4.2 = 0.7 s, or 0.7 / 4.9 ≈ 14% less time to 100. That is the restyling’s performance argument. It is paid for, on these sheets, with higher mixed use and higher CO2, not with more horsepower.

Mercedes Maybach GLS weight, dimensions, and size

Kerb weight is 2785 kg on both versions. Gross weight is 3250 kg on both. Payload from those two figures is 3250 − 2785 = 465 kg either way. Ground clearance is not measured. Overall length, width, height, and wheelbase in millimetres or feet are not measured — searches for “Maybach GLS 600 dimensions in feet” cannot be answered from this file.

Wheel sizes are the same pair: 285/45 R22 and 325/40 R22. Tank 90. Mass does not explain the 0–100 change: both cars carry 2785 kg.

Power-to-weight:

The restyling is 0.01 kg/hp heavier on paper — a rounding of 1 hp on the same kerb mass. It is not a lighter car. Anyone buying the later GLS 600 for a better weight-to-power ratio will not find that ratio in these numbers.

Gross-to-kerb ratio is 3250 / 2785 ≈ 1.17 on both. The chassis capacity figure does not change with the restyling.

Mercedes Maybach GLS 600: which version to choose

There is only one named version. The choice is which dated GLS600 4.0 AT EQ Boost 4Matic.

Take the 2019-01-01 – 2023-03-31 GLS600 4.0 AT EQ Boost 4Matic (558 hp) if mixed economy and CO2 matter more than the sprint. It is the only car here with mixed 12 and CO2 273. It is 1 hp stronger. It is 0.7 s slower to 100. Same 250 top speed, same 2785 / 3250 kg, same 90 litre tank, same 3982 cc Gasoline Turbo AWD Automatic 9. City, highway, and ground clearance are not measured, so do not assume this phase is “the efficient one” beyond the mixed column.

Take the restyling from 2023-04-01, still GLS600 4.0 AT EQ Boost 4Matic (557 hp) if 0–100 is the deciding number. 4.2 s versus 4.9 s is the largest performance gap in the file. You do not get more displacement, more torque, more gears, or less mass. You get a 1 hp / 1 kW cut, mixed 14.1 instead of 12, and CO2 320 instead of 273. Production has no stop date in the data, so this is the current catalogue state of the model.

Do not choose by badge math. “600” is not 600 hp. “EQ Boost” is in the version name on both cars; there is no separate electric range or kW-boost figure in the data. There is no GLS 680, GLS 1000, or Maybach GLS sedan here to step up to. Interior, price, and cars for sale are not measured.

Do not choose by dimensions or clearance. Size in feet, millimetres, and ground clearance are not measured. Wheel diameter is R22 on both; tyre section is 285 front-pattern and 325 rear-pattern in the listed sizes, identical across phases.

If both cars are available, the trade is explicit: −1 hp, −0.7 s to 100, +2.1 mixed consumption, +47 CO2, mass and tank unchanged. The earlier GLS600 4.0 AT EQ Boost 4Matic is the lower mixed-use, higher-peak-power car. The later GLS600 4.0 AT EQ Boost 4Matic is the quicker 0–100 car. That is the whole version-to-version difference this catalogue can support.
