2021 Mercedes-Benz AMG GT 63

Being based on the much more practical AMG E 63, the Mercedes-Benz AMG GT 63 has a comfortable yet luxurious cabin setup. The seats are sporty yet comfortable and coupled with the adaptive air suspension you get a forgiving ride quality. Although the trunk of the AMG GT 63 is the smallest in the segment that does take away a few points from practicality. That said, all this doesn’t come cheap and the base Mercedes-Benz AMG GT 63 starts at $140,600. The rivals include Audi RS7, Porsche Panamera, BMW M8 Gran Coupe. 

The 2021 Mercedes-Benz AMG GT 63 is available in two versions. The base is the AMG GT 63 that gets a 577 hp, Bi-turbo V8 and the other one is the AMG GT 63 S that gets a 630 hp, Bi-turbo V8. Both the trims get almost identical features with the major difference of the higher tuned engine in the AMG GT 63 S. Few other extra feature that the AMG GT 63 S gets over the AMG GT 63 is a 20-inch AMG alloy wheel, race and drift mode, and DINAMICA wrapped AMG performance steering wheel.

As for the AMG GT 63, it gets standard features like Nappa leather upholstery, full-LED exterior lighting, 19-inch alloy wheels, a 12.3-inch MBUX infotainment system, Burmester surrounds sound system, heated and ventilated front seats, power-adjustable front seats with memory function, sunroof, AMG body kit, fixed rear seats with carbon fiber seatbacks, power-folding side mirrors, keyless-go, brake hold feature, adaptive high beam assist, rearview camera, heated windshield washer system, etc.

Although the 2021 Mercedes-Benz AMG GT 63 comes with a bevy of features Mercedes-Benz has still given it few optional packages and standalone features. Optional packages include an Executive rear seat package for $3,550, warmth and comfort package for $1,050, driver assistance package for $1,950, AMG dynamic plus package for $3,000, etc. Standalone optional features include a 3D premium Burmester sound system, panoramic sunroof, heated steering wheel, surround-view camera, etc.

We Recommend:

As the 2021 Mercedes-Benz AMG GT 63 is already pricier than its rivals in the segment we recommend sticking to the AMG GT 63 variant unless you can exploit the extra 63 horses in the AMG GT 63 S variant. As for the steep price difference of approximately $21,000 you just get a few more horses, bigger wheels, and race and drift mode. These upgrades don’t justify the premium over the AMG GT 63.

The 2021 Mercedes-Benz AMG GT 63 gets a handcrafted AMG 4.0-liter bi-turbo V8 engine that puts out 577 hp and 590 lb-ft of torque while the same engine in the AMG GT 63 S churns 630 hp and 664 lb-ft of torque. Both the models get a 9-speed AMG Speedshift automatic transmission. In the same fashion AMG Performance, 4Matic+ AWD configuration is standard on both cars. 

The AMG GT 63 with all that power has a claimed 0-60 mph time of 3.3 seconds while the higher-powered AMG GT 63 S shaves off three-tenths of a second and does 0-60 mph in 3.1 seconds. The AMG GT 63 can reach an electronically limited top speed of 193 mph while the AMG GT 63 S can do 195 mph before the speed limiter kicks in.

All the rivals get a twin-turbo V8 under their hood but none put similar power and torque figures. The most powerful car in this comparison is the Audi RS7 that puts out 591 hp and 590 lb-ft of torque while the Porsche Panamera GTS is the least powerful here putting just 473 hp and 457 lb-ft of torque. 

Audi RS7 is the most powerful sedan that does the fastest 0-60 mph time of 3.0 seconds and the fastest quarter-mile in 11.3 seconds. Surprisingly the least powerful Porsche Panamera beats the AMG GT 63 and BMW M850i by a margin, clocking a 0-60 mph time of 3.2 seconds and covering a quarter-mile in 11.7 seconds.

2021 Mercedes-Benz AMG GT 63 Ride and Handling:

If you have a slight understanding of how an AMG car is different from a regular Mercedes-Benz then this needs no explanation of how well the AMG GT 63 or the 63 S handles and rides. For those who are still not privy to this let us paint you a picture to give you a clear idea. The Mercedes-Benz AMG GT 63 rides on AMG sports suspension and comes with adaptive damping. Then there is the AMG Performance 4Matic+ AWD system as standard on the AMG GT 63. Both these work in conjunction to give you phenomenal grip levels and forgiving ride quality. Yes, you heard that right, among the other cars of this segment the AMG GT 63 has the most comfortable ride provided you are in comfort mode. 

All the other modes only prefer smooth tarmac and would become very uncomfortable on normal roads. While the saving grace here is the individual mode which lets you individually control each setting. Simply put you can set the suspension setting to most comfortable and rest all parameters to the highest level. As for the handling the AMG GT 63 has also got you covered here with the AMG Performance 4Matic+ AWD system. The system won’t let you lose control even when going hard around the corner. While the available Drift Mode is given in case you want to have some fun around the track without losing control of the wheel. 

2021 Mercedes-Benz AMG GT 63 Braking:

The 2021 Mercedes-Benz AMG GT 63 is a brute and is capable of hair-raising performance. Thus to put a leash on it, Mercedes-Benz has slapped in AMG performance brakes with active brake assist and adaptive braking technology. But only electronic aids won’t suffice until you have big brake rotors to put enough stopping power. That said, AMG GT 63 gets 15.8-inch rotors at the front and 14.2-inches rotors at the rear. The overall result of this is that the AMG GT 63 takes 127 feet to stop from 60 mph speed.

The braking distance figures of the rivals are not available with us so we will compare the rotor size to assess who gets the bigger set of rotors among all. The Audi RS7 gets the biggest front rotors that measure 16.5-inches while the BMW M850i Gran Coupe gets the biggest rear rotor measuring 15.0-inches. The AMG GT 63 has the smallest front rotors while the Porsche Panamera GTS gets the smallest front rotors. 

A bi-turbo V8 under the hood and an AMG car isn’t the right mixes that result in a good fuel economy and if you have a heavy foot then even the EPA estimates can be breached to a new low. That said, the 2021 Mercedes-Benz AMG GT 63 has an EPA estimated gas mileage of 16 mpg in the city, 21 mpg on the highway, and 18 mpg combined. The AMG GT 63 gets a 21.1-gallon fuel tank that helps you cover a range of 338 miles in the city and 443 miles on the highway.

On paper, the BMW M850i is the most fuel-efficient sedan among all. The BMW M850i has an EPA estimated gas mileage of 17/24/19 mpg in city/highway/combined respectively. The next in line is the AMG GT 63 while the Audi RS7 and the Porsche Panamera GTS share a similar gas mileage figure in the city and combined. That said, the Porsche Panamera GTS has the biggest 23.7-gallon fuel tank among all resulting in a longer range compared to others.

The interior of the Mercedes-Benz AMG GT 63 has been given a cockpit-like look to get a sporty feeling. The interior design has been lifted from other Mercedes-Benz coupe and sports sedans with a minor rework to differentiate the AMG GT 63 from them. The front of the dash gets two big 12.3-inch screens one for the driver’s display and the other for the infotainment. The jet-like AC vents sit in the middle of the wraparound dash. The center console remains busy with lots of controls and switches lying around. Without a doubt, this is not an ergonomically sorted sports car. Coupled this with the restricted outward visibility makes for a double whammy. 

On the bright side, though the high set front seats make for easy ingress and egress, the same is not true for the cramped rear seats. Speaking of seats, the front seats are a set of luxurious and comfortable couches with aggressive bolstering and side wings to hold you in place while attacking corners. The front seats offer heating and ventilation functions. Also, they are power-adjustable and have a memory function. The rear seats are fixed with carbon-fiber seatbacks and believe us it is very claustrophobic sitting back there. The sloping roofline and small greenhouse contribute a lot to this.

Surprisingly even with the sunroof the Mercedes-Benz AMG GT 63 manages the best 40.8- and 38.2-inches of front and rear headroom respectively. The 57.8- and 57.2-inches of front and rear shoulder room also happens to be the best among all rivals. Speaking of rivals, the BMW M850i has the overall most spacious front row while the Audi RS7 has the overall most spacious rear seats among the three.

Even though the cars in this comparison are sports cars, still they need to have a decent trunk space to make them a bit more practical and qualify as a daily driver. The Mercedes-Benz AMG GT 63 with 12.7 cubic feet of cargo space has the smallest trunk. The Audi RS7 with 24.6 cubic feet of cargo space has the best trunk space you can get here. Highlights of the interior include:

• 64-color LED ambient lighting
• Nappa leather upholstery
• Heated and ventilated front seats
• Power-adjustable front seats with memory function
• Rear-window sunshade
• Dual-zone automatic climate control
• AMG illuminated front door sills
• Wireless charging with NFC pairing

2021 Mercedes-Benz AMG GT 63 Infotainment System:

The 2021 Mercedes-Benz AMG GT 63 gets a 12.3-inch touchscreen infotainment system that runs on the latest Mercedes MBUX system. The system gets voice control and the ‘Hey, Mercedes’ keyword activation function. Had these two not been provided then operating the infotainment system would have been a nightmare while on the go. Although Mercedes-Benz has also given a touchpad controller to operate the center screen, it remains a task to operate the infotainment without voice control while driving.

Standard features available with the infotainment system include navigation, a 14-speaker Burmester surround sound system, Apple CarPlay, and Android Auto, Bluetooth, HD Radio, SiriusXM, etc. Optional features include a 25-speaker 3D Burmester high-end surround sound system, AMG head-up display, rear-cabin central touchscreen display, in-car Wi-Fi, MBUX interior assistant, MBUX augmented video for navigation, etc. Highlights of the infotainment system include:

• 12.3-inch touchscreen multimedia display
• Mercedes’ MBUX system
• MB navigation
• Apple CarPlay and Android Auto
• SiriusXM 6-month all-access trial
• Burmester surround sound system
• Voice control
• 3D Burmester High-End surround sound system (available)
• In-car Wi-Fi (available)
• MBUX interior assistant (available)
• MBUX augmented video for navigation (available)

The exterior design and looks of the 2021 Mercedes-Benz AMG GT 63 can be easily mistaken for the Mercedes-Benz AMG E 63 from front and side by any average joe. Although the AMG GT 63 is based on the legendary AMG GT sports car, there is little that both have in common in terms of exterior design. The AMG division has done its best to spill its secret exterior design sauce over the AMG GT 63 to give it a more menacing look. The front hood gets four protruding crease lines running through it giving it a ribbed look. The front fascia comes with a big AMG grille and a slimmer yet powerful set of LED headlights with LED daytime running lights. 

The side profile gets a blacked-out rearview mirror and a clean European coupe silhouette. The AMG GT 63 gets 19-inch AMG 10-spoke alloy wheels that can be upgraded to 21-inch AMG forged twin 5-spoke wheels. Moving to the rear you will see the real differentiator is the rear LED brake lights which are thinner and sharper. The multistage active rear spoiler ducks neatly inside the boot lid and four exhaust pops out from the bottom of the rear bumper. The rear aero curtains neatly integrate into the bumper. The only oddball design is the rear fog lights sitting at the sides of the license plate that look like an extended mustache of the AMG GT 63. 

Dimensionally none of the cars in this comparison are a clear-cut winner here. The BMW M850i is the longest measuring 200.3-inches, the Porsche Panamera GTS is the widest measuring 78.2-inches, and the Mercedes-Benz AMG GT 63 is the tallest measuring 56.8-inches. The BMW M850i is the longest car so by default has the longest wheelbase of 119-inches compared to that the AMG GT 63 has a 2.8-inches shorter wheelbase. Highlights of the exterior features include:

• 19-inch AMG 10-spoke alloy wheels
• Power tilt/slide sunroof
• Multistage active rear spoiler
• LED high-performance headlamps
• Adaptive high beam assist
• LED daytime running lights
• Rain-sensing windshield wiper
• Heated windshield (available)
• 21-inch AMG forged alloy wheels (available)
• AMG aerodynamic package (available)
• Panoramic roof (available)

Expensive cars like the Mercedes-Benz AMG GT 63 hardly make it to the crash-test anvil of the NHTSA or IIHS, so it becomes very difficult for us to paint a clear picture of the safety of the car in question. Nevertheless, as a matter of fact, Mercedes-Benz as a manufacturer has been known to make safe cars. With numerous ‘Top Safety Pick’ awards won by its cars as proof of that. 

That said, Mercedes-Benz has left no stone unturned to ensure the AMG GT 63 packs in top-class safety features and driver-assist functions. The AMG GT 63 comes with an advanced body structure, seven airbags, an electronic stability program, tire pressure monitoring system, speed limit assist, adaptive braking, blind-spot assist, rear cross-traffic alert, etc like features as standard. Highlights of the safety features include:

• Driver attention monitor
• Speed limit assist
• Crosswind assist
• Parking assist
• Blindspot assist
• Rear cross-traffic alert
• Active brake assist
• Mercedes-Benz Emergency Call service
• Evasive steering assist (available)
• Lane change with lane keep assist (available)
• Emergency braking (available)
• Surround-view system (available)

2021 Mercedes-Benz AMG GT 63 Vs 2021 Audi RS7

The Audi RS7 is superior to the Mercedes-Benz AMG GT 63 in lots of parameters. Both of them get a twin-turbo V8 but Audi RS7 is more powerful and three-tenths of a second quicker than the AMG GT 63 in 0-60 mph run. The Audi RS7 has similar fuel economy figures as the AMG GT 63. 

But the Audi RS7 is more spacious and has a bigger boot compared to the AMG GT 63. The final nail in the coffin is the price of the Audi RS7 which is approximately $26,000 less than the AMG GT 63’s price. So the Audi RS7 makes a whole lot more sense than the AMG GT 63. 

2021 Mercedes-Benz AMG GT 63 Vs 2021 Porsche Panamera GTS

The 2021 Porsche Panamera GTS might be an oddball Porsche but it still has the Porsche DNA running in it. Even after putting out far less power and torque from its twin-turbo V8 Porsche Panamera GTS manages to beat the AMG GT 63 in 0-60 mph run by one-tenth of a second. The Porsche Panamera GTS offers one mpg less gas mileage in the city and combined compared to the AMG GT 63. 

But the Panamera GTS has a bigger boot and almost similar cabin space as the AMG GT 63. Although it might look that Porsche Panamera GTS is cheaper than the AMG GT 63 but believe us if you go on equipping your Panamera GTS with all the features that AMG GT 63 offers as standard you can easily look at the $1,50,000 price tag for the Panamera GTS.

2021 Mercedes-Benz AMG GT 63 Vs 2021 BMW M850i Gran Coupe

BMW the arch-rival of Mercedes-Benz since eons for sure couldn’t let it pass without having a worthy competitor to the AMG GT 63. The BMW M850i Gran Coupe has given a tough fight to the AMG GT 63 so far. But BMW M850i’s less powerful engine makes it lose out to the AMG GT 63 by two-tenths of a second in the 0-60 mph run. 

Lesser power does help the BMW M850i to return a higher gas mileage, especially on the highway compared to the AMG GT 63. As far as cabin space and trunk space are concerned both the cars offer similar space. Thus to conclude if you can live with the slightly lower performance then the BMW M850i could save you a lot of money as it is more than $30,000 cheaper than the AMG GT 63.

The Mercedes-Benz AMG GT 63 is the perfect toy for a financially strong person. The car is a hell of a lot expensive and gets easily run down by cars costing a lot less. But the unmatched luxury and style quotient of the Mercedes-Benz up to some extent justify the premium pricing. The car is a true sleeper as it is comfortable enough for being a daily driver and when put in its best settings can shame lots of sports sedans on the track. The cabin space, especially the head and shoulder room is particularly generous but the trunk space is a bit tight.

The exterior looks are one of the best among the sports coupe segment and in a true sense have a calm demeanor that hides the monster underneath. That said, if you have lots of cash to splurge and want to commute to your office in a flashy sports car then the Mercedes-Benz AMG GT 63 makes a lot of sense, otherwise, you are better off in the much cheaper Audi RS7 or the BMW M850i.
