When it comes to luxury sports coupes, very little comes close to offering the drama and performance of the 2020 Mercedes-AMG S63 Coupe. Its handcrafted 4.0-liter twin-turbo V8 churns out a mighty 603 horsepower and 664 lb-ft of torque, which is available virtually everywhere in the rev range and makes this grand tourer coupe feel more like a bullet train than an actual car. This all-wheel-drive monster gets a nine-speed MCT automatic gearbox as well as adaptive dampers and a high-performance brake system. Its stunning interior is one of the best we've experienced in recent memory but comes with almost too much technology, and less technically inclined drivers could get overwhelmed by it all. Competitors such as the BMW M8 Coupe might offer similar performance figures but can't match this German coupe for sheer drama and opulence.
The S-Class Coupe, first released in 2015, received a minor refresh in 2018 and is due for replacement in the near future. For 2020, the hugely extravagant and powerful S65 has been axed, leaving only the S63 as the sole AMG model. Minor changes for the new year include the addition of keyless access, massaging front seats, a surround-view camera, and push-button start as standard.

4.0L Twin-Turbo V8 Gas
The 2020 Mercedes-AMG S63 Coupe looks like one fell swoop of muscle and class, and seeing one in the wild is an experience in itself, and we think the stretched out S63 looks like something a modern-day Cruella de Vil would love to own. Standard exterior features for 2020 include a pillarless window design, LED headlights, and OLED taillights, as well as a set of 20-inch AMG five-spoke wheels, while the AMG front and rear bumpers include signature quad tailpipes.
The sprawling S63 Coupe measures 198.9 inches in total length, is 56 inches tall, and 83 inches wide when including the wing mirrors. The whole deal rolls on a 115.9-inch wheelbase, and the curvy body has a drag coefficient of 0.33. Curb weight is a significant 4,685 lbs.
Each S63 Coupe is powered by an individually handcrafted 4.0-liter bi-turbo V8 engine, which in S63 guise, develops 603 hp between 5,500 and 6,000 rpm and a massive 664 lb-ft of torque available between 2,750 and 4,500 rpm. Power is sent to all four wheels via an AMG-tuned 4MATIC+ permanent all-wheel-drive system with fully variable torque split, and an AMG nine-speed automatic transmission with steering-wheel-mounted shift paddles. Mercedes-AMG claims a zero to sixty sprint time of only 3.4 seconds, which we fully believe, thanks to a seemingly endless wave of torque from the moment you plant your foot on the gas.
With a curb weight upwards of 4,500 pounds, it should be clear to anyone with a little motoring know-how that the S63 Coupe was never intended to hit the perfect apex around a tight and technical track; rather, the S63 thrives as a comfortable GT cruiser. The best word to describe the driving experience of the S63 Coupe is dignified. It feels sure-footed, and despite its sheer size, is easily pointed into a corner with accuracy. The S63 Coupe will glide over rough roads with ease, but don't ask it to tuck into a tight corner like a Ford Fiesta ST. Its 4Matic AWD system claws at the road, which means that corner exits can feel like being launched out of a catapult. It's a capable handling car, but it prefers traveling at lightspeed on long stretches of open road.
What do you get when you cross a twin-turbo V8 with an S-Class? An oil crisis. Seriously though, the 2020 Mercedes-AMG S63 Coupe is a seriously heavy drinker, but not that it matters much; when you're playing in this league, fuel costs are but a trifle. The EPA rates the S63 at 17/27/20 mpg city/highway/combined. The sportier AMG GT is thirstier at 16/22/18 mpg, and arch-enemy BMW's M8 will manage a thirsty 15/21/17 mpg. Mercedes-AMG has fitted the 2020 S63 Coupe with a large 21.1-gallon fuel tank, which will see this German bullet travel for up to 422 miles on one fill.
One of the things we love most about the S63 Coupe is its beautifully supportive front seats, which will keep you comfortable for miles on end. Interior space is good too: front seat passengers won't complain about the 41.7 inches of legroom, and those in the back also get a healthy 33.4 inches. It's a bit tight for adult passengers, but most will find it comfortable enough, once they've managed to get past the trickiness of climbing in and out. Headroom comes in at 40 inches in the front and 36.7 inches in the rear. Ingress and egress are tricky, however, as the long doors don't like cramped parking spaces.
One of the biggest reasons why people buy big GT performance cars is so that they can drive them over long distances in the soothing lap of luxurious comfort, and what's usually at the end of a long road trip? A holiday destination, or some other form of leisurely activity that requires a sleepover or two. This means that GT cars should have a modicum of trunk and cargo space at the very least. The good news is that the S63 Coupe offers a good amount of trunk space to pack for a weekend getaway for two people, despite not being class-leading. The official number is 10.4 cubic feet. Inside the cabin, you get the standard glove box and center console bin, as well as narrow door pockets and a small storage nook in front of the center control console. In the rear, there's a fold-out center console with a small storage compartment, too.
You won't be left wanting when it comes to standard features on the 2020 Mercedes-AMG S63 Coupe. The exterior features adaptive suspension, an AMG high-performance composite braking system, and a performance exhaust system, as well as design features such as an AMG-specific grille, all-LED exterior lighting, and OLED taillamps. Inside, the 2020 Mercedes-AMG S63 Coupe gets loaded with premium features such as heated and ventilated Nappa leather, 12-way power front seats with memory and massage function, 64-color LED ambient lighting, keyless entry, soft-close doors, as well as dual-zone automatic climate control, a power rear-window sunshade and a HomeLink garage door opener. Driver assistance features include blind-spot assist, lane keep assist, and rear cross-traffic alert.
The infotainment system in the 2020 Mercedes-AMG S63 Coupe can be intimidating to the less technologically-inclined driver, but once you get used to it, it offers some serious capability. Things start off with a 12.3-inch high-resolution central display and a 12.3-inch digital instrument cluster. Things are controlled by a Mercedes-AMG COMAND system with a touchpad/rotary controller. Infotainment features include integrated navigation, enhanced voice control, Apple CarPlay, and Android Auto integration, as well as Bluetooth audio streaming, dual USB audio ports, an HD Radio receiver, and SiriusXM radio with a six-month trial. The premium Burmester Surround Sound system features 13 high-quality speakers and a 590-watt nine-channel digital amplifier, but it can be upgraded with a 25-speaker Burmester system instead.
While the 2020 version of the S63 is recall-free at the time of writing, several recalls were issued for 2019 models including several driver assist malfunctions and a potential oil leak. Mercedes-AMG offers the S63 Coupe with a four-year/50,000-mile basic warranty, which includes corrosion and drivetrain cover, as well as roadside assistance for the same amount of time and miles.
The $171,400 Mercedes-AMG S63 Coupe has not been crash-tested by the NHTSA or IIHS but comes packed with standard safety features such as blind-spot assist, lane keep assist, and rear cross-traffic alert. Optional features include active steering assist, active blind-spot assist, automatic speed takeover, and congestion emergency braking. There are a total of ten airbags on offer, with dual two-stage front airbags being augmented by dual knee airbags. Pelvic airbags for the front passengers are also standard.
The S63 Coupe is a low-flying GT that looks as good as it goes, and should be considered as one of the best grand tourers on the market at the moment, but, like any car, it does come with its drawbacks. Firstly, that 4.0-liter twin-turbo V8 loves to chug down fuel faster than you can say "this car is not fuel-efficient" and talking about spending lots of money, the S63's starting price of $171,400 is stratospherically high. Smaller issues we had with this car is the sheer amount of technology on offer, which could flummox even the most clued-up drivers. Now onto the good stuff. The S63 Coupe is a gorgeous thing to look at from any angle, and it has one of the best interiors you'll find anywhere, period. Once on the road, it will happily travel at warp speeds in ultra comfort; its a seriously sorted GT car and that engine is simply a masterpiece. Although the options can get pricey, there are so many of them; we like the customizability. All in all, this car is a beautifully crafted bullet train that deserves a bigger part of the spotlight.
This is where things go pear-shaped: the 2020 Mercedes-AMG S63 Coupe packs a price tag that will knock the socks off even the most well-to-do customers. Mercedes-AMG demands a cool $171,400, which doesn't include registration, tax, and a destination fee of $995. To put that price into context, the gorgeous AMG GT Coupe starts at only $115,900, $55,500 less than the S63 Coupe. That's hard to justify, no matter how much you love the S63, and tacking on options pushes the price up exponentially.
Since there's only the one model to choose from, you'll have to decide whether or not you're happy with the base product, which already bristles with technology from the inside out, or one with a few more optional extras added to the long list of standard features. The standard car already offers a crazy number of features such as adaptive suspension, Nappa-leather seats with ventilation and a massage function, as well as dual 12.3-inch displays with a powerful Burmester 13-speaker surround sound system. If we were doing the buying, we'd add the $6,500 AMG Exterior Carbon Fiber Package, and 20-inch AMG forged cross-spoke wheels for an extra $1,700. With the exterior sorted, we move on to the interior. Inside, we'd include the AMG carbon-fiber and DINAMICA performance steering wheel, as well as the $2,250 driver assistance package, which adds features such as active steering assist and active brake assist with rear cross-traffic functionality. All-in, it keeps the cost down at just $179,950.
The 2020 BMW M850i xDrive is another German masterpiece of a coupe that offers great comfort and mind-blowing performance and is one of the better GT cars on the market in the new decade. The 4.4-liter twin-turbo V8 engine lurking under the hood produces 523 hp and 553 lb-ft of torque, so significantly less than the S63, but out in the real world, there's not much between them. Fuel economy for the BMW comes in at 18/25/20 mpg city/highway/combined. We love the M850i's beautifully crafted interior, although it's less opulent and more driver-focused, as well as its impressive list of standard features, including its class-leading infotainment system (even though it lacks Android Auto). On the road, the BMW is an extremely capable cruiser and has a larger trunk for increased practicality. The M850i xDrive is a very capable car, but lacks the drama of the S63, and thus loses out in this comparison.
It is a well-known fact that the Porsche Panamera Turbo is one seriously fast and comfortable car, but can it stack up to the glamorous S63? Firstly, the 4.0-liter twin-turbo V8 under the hood of the Panamera might be less powerful at only 550 hp and 567 lb-ft of torque, but it will still accelerate to sixty in only 3.8 seconds. Fuel economy comes in at 18/25/21 mpg city/highway/combined. Put simply, there's little else that handles as good as the Panamera, and while it can carve corners like a pro, it is still gloriously comfortable. The Panamera's hatchback-style liftgate also aids in practicality, as do the rear doors, and the interior is spacious as well. While it might lack the svelte design of the Mercedes, it's a superior performance car and arguably the more comfortable option.
