The horsepower is a characteristic that most of us pay the greatest attention to. In this comparison, it is the Mercedes SLS AMG Coupe that has by 14 % horsepower more in relation to the Porsche 911 997, which makes this car a bit better in terms of high speed. Because of more horsepower the Mercedes SLS AMG Coupe 6.2 V8 571HP automatic should as well provide somewhat more flexiblility in specific gears.
The Mercedes consumes 5 percent less fuel in the mixed cycle in relation to the Porsche. The Mercedes, which is palced in „S” segment consumes by 3.5 l more amount of fuel than the average in its segment. The average fuel consumption in this class in the mixed cycle amounts to 9.7 l.
The Mercedes SLS AMG Coupe 6.2 V8 571HP automatic has 194 newton meters more torque in relation to the Porsche. The difference at such level is relevant, what means
that the Mercedes will accelerate significantly faster.
The fuel consumption of the Mercedes SLS AMG is 3 % better in comparison to the Porsche 911 997 Coupe 4.0 GT3 500HP manual. Despite the difference is little, in the long term it may make that your vehicle would be noticably cheper to run.

In the „S segment, being represented by the Porsche 911 997 Coupe, the medium acceleration to 100km/h amounts to 7.2 s and is by 3.3 s lower than this of Porsche vehicle.
The top velocity of the Mercedes is greater in comparison to this of the Porsche 911 997 which allows to drive the same distance on the highway in shorter period of time. The difference at the level of 3 km/h is small and is not realy noticable in daily use.
Maximal torque RPM
The RMP where the maximum torque is delivered tells us how fast an engine reaches its best efficiency with increase in rotational speed. The lower rmp or the wider range in which the torque is the highest, the more the engine is flexible and the kick of acceleration should be felt faster.
distance between left and right side of a vehicle directly influences on room in the cabin as well as stability while driving. The width of the Mercedes is larger by 131 millimeters than the Porsche 911 997 Coupe 4.0 GT3 500HP manual and is not really worth considering. The medium for the „S” segment is 1,791 mm and is by 148 millimeters larger than the same feature of the Mercedes SLS AMG Coupe.
Mercedes has 333 millimeters longer wheelbase in relation to the Porsche 911 997 Coupe 4.0 GT3 500HP manual. A longer wheelbase gives more stable and comfortable ride, especially when driving fast. It also gives more storage space. But, vehicles having a longer wheelbase are not as maneuverable as those with a shorter wheelbase.
The Mercedes SLS AMG Coupe 6.2 V8 571HP automatic has 55 percent greater engine size than the Porsche 911 997 Coupe. The difference is substantia. As a result the Mercedes SLS AMG Coupe 6.2 V8 571HP automatic should accelerate faster and be able to reach higher top speed. On the other hand larger engine size results in worst fuel economy.
The Mercedes SLS AMG Coupe 6.2 V8 571HP automatic is 5 percent longer than the Porsche 911 997 Coupe 4.0 GT3 500HP manual.

Model release date
Given that the Porsche 911 997 Coupe was launched only 5 years before the Mercedes SLS AMG Coupe, the gap between technology used in both vehicles shouldn’t be really huge, however, the Mercedes might have a bit more advanced solutions applied in it.
To those who appreciate more functional use of a vehicle and don’t want to struggle with complications that stems from the manual transmission we recommend vehicles with automatic gearbox. To those who have a flair for sport driving a stick shift might be better as it gives a control of rmp range in which a shift take place.
