For 2021 the AMG 63 Coupe has been fully redesigned and now debuts among the seventh generation of S-Class models. It happens to be the best and only option in this price range and specific segment as the BMW M8 is not available for 2021. Hence we have taken the 2020 M8 Competition to compete against the AMG 63 Coupe along with the Porsche 911 Turbo and the Bentley Continental GT V8. These are magnificent machines but the Porsche focuses more on performance while the Continental GT V8 costs much more than the Mercedes. So let’s see how the AMG 63 Coupe performs against these machines under various parameters.

We Recommend

The AMG S 63 Coupe is a standalone trim that stands above the S 560 Coupe. The S 63 as it comes in the base variant itself is fully loaded with a lot of bells and whistles. But since you are already made up your mind to buy this one and are rich enough to get this machine, we recommend you go all out. The AMG Carbon Fiber and Night Packages for a more serious exterior look and the AMG Aerodynamics Package can opt for even better performance.

2021 Mercedes-Benz AMG S 63 Engine and Performance

The engine under the hood of the AMG S 63 Coupe is an AMG-developed handcrafted 4.0 L V8 Biturbo that produces a massive 603 hp and 664 lb-ft of maximum power and torque. The maximum behemoth amount of this Coupe’s torque is available from as low as 2,750 rpm and is maintained so till 4,500 rpm. The engine is mated to an AMG Speedshift MCT 9-speed transmission which Mercedes claims to be the world's first 9-speed multi-clutch transmission. 

The transmission is a beast delivering fast upshifts and rev-matching downshifts. The power is sent to all four wheels by the AMG Performance 4MATIC+ all-wheel-drive system which can transfer power between the rear wheels and all four wheels according to the need and driving condition. It is also equipped with a Race Start function that unleashes the maximum performance of the car effectively during drags.

The 2021 Mercedes-Benz AMG S 63 Coupe can reach a speed of 60mph in just 3.0 seconds which is super impressive considering the heft of the machine and that no compromises are made in terms of interior features to attain this performance. The S 63 can zip through the quarter-mile in 11.2 seconds which is also an impressive number. This AMG is also fitted with an AMG performance exhaust system with a free-flow design as standard which seriously elevates the soundtrack of the machine into a more strong and growly note which is music for the ears of an enthusiast. There are also pops and crackles during upshifts and downshifts. Overall on the powertrain side, this machine is a killer performer.

The 2020 BMW M8 Competition takes the cake in terms of sheer performance as it is the fastest even though it is less powerful than the Merc. The M8 Competition Coupe also has a significant price advantage over all of its competitors making it the absolute king in the performance segment while also being the cheapest even while making no compromises in speed. The Mercedes is undoubtedly the most powerful among all of the cars compared here, but its higher weight holds it back from achieving the best-in-class speed against the significantly lighter BMW and the super-lightweight Porsche 911.

How well does the 2021 Mercedes-Benz AMG S 63 Coupe Drive and Handle?

Being a hefty car with so much weight, the handling is not expected to be the best aspect of the S 63 Coupe. But it surprises and impresses us with nimble handling in most situations. However, handling and driving dynamics are not as engaging as rivals like the BMW M8 or Porsche 911 which can be termed as proper sports cars delivering excellent driving dynamics and corner-carving abilities. 

The Mercedes however focuses equally or even a bit more on the comfort side of the spectrum also, while maintaining a balance between performance and comfort. The AMG S63 comes fitted with AMG Adaptive Sport Suspension based on AIRMATIC along with Adaptive Damping System PLUS as standard. Both of these systems work to adjust to even the minute undulations on the road and adjust the suspension setup accordingly to deliver the maximum ride quality. The system provides three selectable modes which are Comfort. Sport and Sport+.

2021 Mercedes-Benz AMG S 63 Coupe ride and handling

There is an issue, which is actually not an issue. The thing is that the Comfort mode puts the suspension setup into a too soft setting affecting handling while the Sport+ mode makes it aggressively stiff and affects ride comfort. The middle Sport mode is the best option among all of them. Overall it is a great-handling machine considering it as a super luxurious coupe, but if what you want is a coupe more slanted towards the performance side, better rethink your choice. 

How efficient is the braking performance of the 2021 Mercedes-Benz AMG S 63 Coupe? 

The S 63 AMG is fitted as standard with AMG high-performance brakes consisting of perforated and internally ventilated compound discs in all four wheels. The front discs are 15.4 inches in size with silver-painted 6-piston fixed-type calipers. And the rear brakes are 14.2 inches in diameter coupled with single-piston floating calipers. These brakes are strong, but the S 63 with its huge size, is not easy to bring to a stop. 

The car stops at a distance of 121ft. from a speed of 60mph. However, this AMG Coupe can opt with the available AMG High-performance Ceramic Composite Braking System which was specially developed to cut weight and for better braking performance on the track. These consist of carbon-fiber-reinforced ceramic discs that can endure extreme heat and braking pressure.

The 2021 Porsche 911 Turbo and the BMW M8 Competition are the absolute best in terms of braking in the segment. The Continental GT however is equipped with the best and largest set of brakes among all of the competition. It performs super well even while being the heaviest machine of the bunch. The Mercedes performs quite well in terms of braking but compared with the competition it is not strong enough in the standard configuration.

2021 Mercedes-Benz AMG S 63 Fuel Economy

8.0/10

When it comes to fuel economy, the Mercedes performs very well. The AMG S 63 has a transmission that is efficient and delivers high fuel efficiency figures. The Mercedes-Benz AMG S 63 delivers a fuel economy of 16mpg in the city, 26mpg on the highway, and a combined efficiency of 19mpg. The coupe also gets a large fuel capacity of 21.1 gallons which results in a range of 338 miles in the city, 549 on the highway, and a combined range of 401 miles.

The Mercedes AMG S 63 and the Bentley Continental GT are the better performers in terms of fuel economy. The BMW M8 Competition and the 911 Turbo performs lower than the other duo delivering an identical combined fuel economy of 17 mpg. The Bentley and the Mercedes also come with larger fuel capacities providing better range than the others. The Mer and the Continental GT despite being the larger ones still come with better fuel economy and range. 

2021 Mercedes-Benz AMG S 63 Interior

8.0/10

The AMG S 63 features an extremely luxurious cabin, if not the most luxurious one of the price paid, and the price paid is definitely a bit too high. The cabin is of super high quality and everything is covered in ultra-premium elements and materials. The cabin can be trimmed in Black Poplar/Burl Walnut/Satin Grey Ashwood as standard free-of-cost options while there are also other paid more premium options including design Black Piano Lacquer wood and AMG Carbon Fiber/Black Piano Lacquer.

2021 Mercedes-Benz AMG S 63 Exterior

6.0/10

It is an absolute beauty. The exterior has a fluidic nature with sleek lines and curves spreading elegance all around the Coupe. The design looks amazing from whichever angle you look at whatever portion of this S-Class Coupe. The AMG S 63 does lack some aggression and doesn’t flex the amount of power it’s got under the hood through its exterior design language very well. But that is not a bad thing, Mercedes significantly states that this is a super-expensive super -luxurious vehicle which it is. The design features a pure pillarless profile as Mercedes calls it which streamlines the S 63 Coupe so much that it has a flowing nature while seen driving around.

2021 Mercedes-Benz AMG S 63 Coupe 

The S 63 features an all-LED lighting setup which consists of all-LED headlamps and OLED taillamps. The headlights can also be upgraded to ones with Swarovski crystal accents that consist of genuine Swarovski crystals which look astonishing and beautifully alien. The standard wheels on the S 63 are 20-inch AMG 5-spoke alloy wheels while the available options include 20-inch AMG forged 10-spoke/cross-spoke, silver/black, and also AMG forged 10-spoke, silver wheels.

All of the cars in the comparison are extremely beautiful based on their distinct design languages. All of these machines actually please my eyes as all of them have a lot of character in their own specific style. The Mercedes is the classiest and most elegant of course while being a little subtle and stealthy. 

The BMW is the most aggressive-looking one with impressive cuts and lines all around the exterior stating that it is meant for serious performance. The Porsche looks, well mostly like how it always was and you either love it so much or just hate it. The Bentley is the most flashy and looks the most luxurious while also having the largest footprint and heft. The following are some of the most important exterior features of the AMG S 63 Coupe-

2021 Mercedes-Benz AMG S 63 Coupe vs 2021 BMW M8 Competition

The Mercedes is more luxurious and more premium-looking while offering more space and comfort. It also provides a better fuel economy. In terms of power outputs, the S 63 holds up very near to the M8 Competition offering a load of it. However, the BMW is much less expensive while delivering much better handling and driving dynamics. The choice is between luxury extravaganza and razor-sharp handling while both of them are great cars and the choice is subjective.

2021 Mercedes-Benz AMG S 63 Coupe vs 2021 Porsche 911 Turbo

The Porsche 911 turbo has always been an extreme performance machine offering precise and engaging handling and driving dynamics. The Porsche is surely the better performer even though it’s slower than the Merc in terms of straight-line drag times. It tackles corners with all the aggression and is more enjoyable to drive while also being significantly lighter. The Merc, however, is the more comfortable and spacious option offering much more space and better ride quality. 

2021 Porsche 911 Turbo

2021 Mercedes-Benz AMG S 63 Coupe vs 2021 Bentley Continental GT V8

The 2021 Bentley Continental GT V8 and the Mercedes AMG S63 Coupe are the most similar ones in this comparison. Both of them are large, hefty, super luxurious Coupes offering great performance and lots of customization options. The Bentley is more on the heavier side while also being the more expensive one. Considering the lower price and better performance of the Mercedes, the AMG S 63 would be the better option unless you’re in love with the flashy, signature looks of the Bentley.

2021 Mercedes-Benz AMG S 63 Final Verdict

It’s a superb and unique choice for the price paid. The price is actually on the higher side, but it has been brought down significantly from the last model year’s price tag. The 2021 Mercedes-Benz AMG S 63 is a premium blend of superb performance and extreme luxury. It offers great power outputs and efficiency while being ultra-comfortable and feature-rich. There are not many cars that do this with such grace and perfection. So if you want a super luxurious coupe with enough space and all the comfort for accommodating four people that you can also drive around with enthusiasm this one would be a great option under $200K.
