4.43K 0

More compact, cheaper and less powerful than the SLS AMG, AMG-GT landed on the territory of Porsche 911. First static comparison.


With a maximum output range between 462 and 510 HP, more compact, with classic doors instead of gullwing doors and cheaper than the SLS AMG, the AMG GT landed exactly on the territory between 911 Carrera S Coupe (400 HP) and 911 Turbo (520 HP).

The base version of the AMG GT delivers 462 HP and a maximum torque of 600 Nm between 1,600 and 5,000 revs from the new 4 litre V8 bi-turbo. By comparison, 911 Carrera S Coupe has an aspirated 3.8 litre 6 cylinder boxer engine with 400 HP and 440 Nm at 5,600 rpm.

Porsche has the advantage of a low kerbweight of only 1,415 kg, compared with 1,540 kg for the AMG GT. But thanks to the 62 HP additional power, AMG GT accelerates from 0 to 100 km/h in only 4,0 seconds, which represents 0.3, respectively 0.1 seconds quicker than the 911 Carrera S Coupe with PDK, respectively PDK with Sport Chrono Plus package. With PDK, Carrera S Coupe is more economical (fuel consumption 8.7 l/100 km) than the AMG GT which announces 9.3 l/100 km. Without the PDK, the Porsche is by 9.5 l/100 km hungrier. The maximum speed is, in both cases, above 300 km/h, with 302 km/h for the Porsche and 304 km/h for the Mercedes.

Both cars have a seven speed dual clutch gearbox (optional in the Porsche 911 Carrera S). The Mercedes AMG GT comes standard with mechanical rear locking differential, meanwhile the Porsche standardly offers a mechanical limited slip differential with PTV in combination with a 7 speed manual geabox and optional PDK gearbox coupled with an electronically controlled rear differential and PTV Plus.

Both cars have an adaptive drive train, but the Mercedes offers more adjustment options. The Porsche Active Suspension Management (PASM) has two manually selectable damping modes, meanwhile the AMG Ride Control allows choosing between Comfort, Sport and Sport Plus (standard on AMG GT S, optional at AMG GT). More than that, the AMG Dynamic Select for the drive train also has an Individual Mode together with the existent Controlled Efficiency, Sport and Sport Plus modes.

The top version of AMG GT delivers 510 HP and a maximum torque of 650 Nm from 1750 to 4,750 rpm, attacking the 911 Turbo. Both cars have a standard high-tech configuration with adaptive suspension, dual clutch 7 speed gearbox and electronically controlled rear differential (with PTV at Porsche). With a unique bi-turbo charging with variable turbine geometry, 911 Turbo delivers 520 HP and a maximum torque of 660 Nm between 1,950 and 5,000 revs (710 Nm between 2,100 and 4,250 rpm with overboost function of the Sport Chrono package). With a kerb weight of 1,595 kg, the Porsche is 25 kg heavier than the AMG GT S, but accelerates quicker to 100 km/h, probably because of the additional power of 10 HP (power/weight ratio is 3.06 kg/HP in the Porsche and 3.08 kg/HP in the AMG GT S) and active aerodynamics: 3.4 seconds (even 3.2 seconds with the Sport Chrono Package) compared with 3.8 seconds for the AMG GT S. But in this case, the Mercedes has not had the last word yet. There are rumours about a Black Series version with aditional 50-60 HP. The former SLS AMG had one with 60 HP more.

The Porsche reaches a maximum speed of 315 km/h, while the Mercedes limited the maximum speed of the AMG GT S at 310 km/h. The fuel consumpion is 9.5 l/100 km for the Mercedes and 9.7 l/100 km for the Porsche.

Mercedes does not communicate the exterior dimensions, neither the prices of the AMG GT. But after the first live preview, the car is smaller than SLS AMG and has approximately the same footprint like the 911. The first impression is that the AMG GT is a little wider than the 911.

There are no official informations about the price either, but rumours claimed that the AMG GT will be around 50,000 euros cheaper than the SLS AMG. This means a start price of around 130,000-135,000 euros. A 911 Carrera S Coupe with PDK costs 108,683.50 euros, meanwhile the 911 Turbo costs 165,149.00 euros.

So, the AMG GT is very well positioned in comparison to the 911 family. The only thing which is missing, if you look at the Porsche family, is a four wheel drive version and a cabrio version. But a cabrio version is easily to be developed from the coupe version.
