The Mercedes-AMG GT SUV has been revealed as a battery-electric performance SUV with up to 860 kW, a 128 kWh battery and a claimed 710 kW DC charging peak.
Two things need saying before the numbers. The power figure is being reported three different ways, and Mercedes itself calls the charging claim provisional and uncertified.
860 kW, 1,169 hp or 1,153 hp?
All three are the same car. The difference is which horsepower you mean.
Mercedes states 860 kW (1,169 hp), and that 1,169 figure is metric PS. Convert the same 860 kW into mechanical horsepower and you get 1,153 hp, which is the number most American outlets print.
So if one site says 1,169 and another says 1,153, neither is wrong and there is only one SUV. The cleanest way to avoid the confusion entirely is to quote the kilowatts, which is what Mercedes leads with.
The Full Variant Specifications
Three versions were announced. Where two values appear, the first is the 106 kWh battery and the second the 128 kWh.
| GT 53 | GT 55 | GT 63 | |
|---|---|---|---|
| Motors | Two | Three axial flux | Three axial flux |
| Peak output | 400 kW | 600 kW | 860 kW |
| Continuous output | 270 kW | 530 kW | 530 kW |
| Max drive torque | 800 Nm | 1,860 Nm | 2,000 Nm |
| 0–100 km/h | 4.2 s | 3.1 s | 2.7 s |
| 0–200 km/h | 14.6 s | 9.9 s | 7.2 s |
| Battery, net | 106 kWh | 106 / 128 | 106 / 128 |
| Max DC charging | 600 kW | 600 / 710 | 600 / 710 |
| WLTP range | 597–668 km | up to 700 km | up to 700 km |
Every variant uses an 800 V system. Top speed is 250 km/h on the GT 53 and 270 km/h on the other two, and both require the optional Driver's Package.
Mercedes quotes those “hp” conversions as PS throughout: 400 kW is 544, 600 kW is 816, 530 kW is 721 and 860 kW is 1,169.
There is also a second set of acceleration figures circulating, slightly quicker, because the German convention of discounting the first 0.3 metres of a launch is quoted separately. On that basis the GT 63 reads 2.5 seconds rather than 2.7.
The Number Nobody Is Printing
Look at the continuous output row again, because it reframes the whole range.
The GT 63's 860 kW is a peak. Sustained, it makes 530 kW — and so does the GT 55. The two cars have identical continuous output.
The flagship's entire advantage over the mid variant lies in how much it can summon briefly. That is not a criticism, since brief is exactly when you want it, but anyone weighing the two should know the gap is narrower than 860 against 600 suggests.
Why Axial-Flux Motors and 800 Volts Matter
Two technical choices sit behind these numbers, and both are worth a sentence because they explain how the figures are possible at all.
Most electric cars use radial-flux motors, where the magnetic field runs outwards from the shaft. An axial-flux motor routes it along the shaft instead, which allows a much flatter, disc-shaped unit that produces more power for its weight and takes up less room.
That is why three of them fit here without the car becoming absurd, and why the mid and top variants get them while the entry car uses a conventional pair.
The 800-volt system is what makes the charging claim arithmetically possible. Power is voltage multiplied by current, so doubling the voltage halves the current needed for the same power — and current is what generates heat in cables and connectors. At 400 volts, 710 kW would require a current no practical cable could carry.
Why the Range Is a Band, Not a Number
Notice that the GT 53 is quoted at 597 to 668 km rather than a single figure, and the bigger battery at 620 to 700 km.
That spread is not uncertainty about the battery. It is the difference that wheels, tyres, aerodynamic options and equipment make within the same model, and WLTP reports the best and worst configurations rather than averaging them.
The practical lesson is to find out which end of the band your specification sits at. A car ordered with the largest wheels will be nearer the bottom of that range, and on these figures the difference between the two ends is around 70 to 80 kilometres.
710 kW Charging, and Mercedes' Own Warning
On the 128 kWh battery, Mercedes claims that “with up to 710 kW of charging power, up to 450 kilometres of WLTP range can be added in 10 minutes”. It also quotes 10 to 80 per cent in up to twelve minutes, or eleven on the smaller pack.
Now the part that belongs beside it rather than in a footnote. Mercedes states that these figures are provisional, with no values confirmed by an officially recognised testing organisation, no EC type approval and no certificate of conformity, and that they “may therefore differ from the official values”.
A detail that shows how provisional. The press release says 450 km in ten minutes while the official model page says 454 km. For the 106 kWh pack the release's text says 380 km and its own table says 386.
Those are small gaps and they are not a scandal. They do tell you that the numbers are still moving, which is the correct way to read every figure on this page until certification lands.
What 710 kW Would Actually Mean Here
Charging speed is a handshake between two devices, and the slower one wins. A car capable of 710 kW plugged into an ordinary DC charger draws what the charger can give, not what the car can accept.
Hardware at this level sits at the very frontier of what exists anywhere, and it is not something you will find on a Pakistani forecourt. Our charging station guide and our motorway charging guide cover what is actually installed.
The same caution applies to range. A 700 km WLTP figure is a laboratory result, and the gap between a test cycle and a hot-weather motorway run is substantial — we went through why in why electric range drops below the rated figure.
Price and When You Can Order One
Only one variant is orderable. The GT 53 opened for orders on 20 October, from €113,050 — a non-binding German recommended retail price that includes 19% VAT, which matters if you are comparing it against a pre-tax American figure.
The GT 55 and GT 63 follow in spring 2027, and neither has a price. So the 113,050 euro figure is not an entry point to the fast versions; it is the price of the only one you can currently buy, with the other two months away and unpriced.
Mercedes-AMG GT SUV Price in Pakistan
There is no announced Pakistan price, no confirmed local launch and no booking process.
We are also not going to estimate one. Converting a German VAT-inclusive price and adding assumed duties would produce a figure that gets quoted as fact, and the landed cost of a battery-electric vehicle at this value depends on duty treatment nobody should guess at.
If a local figure appears from a dealer or an importer before Mercedes announces one, treat it as an indication subject to change rather than a price. For what buying an EV here actually involves, our guide to buying an EV in Pakistan covers the questions worth asking.
Final Thoughts
As a piece of engineering the GT 63 is extraordinary: three axial-flux motors, 2,000 Nm, 800 volts and a claimed charging rate beyond anything on sale. As a set of published numbers it is still provisional, and Mercedes says so itself in writing.
So read the kilowatts rather than the horsepower, note that the GT 55 matches the GT 63 on continuous output, and remember that only the GT 53 can be ordered today. Everything else is a specification waiting on certification.
