The novelty of the AMG C 63 sedan has risen recently after Mercedes-Benz announced that they are all set to ditch the twin-turbo V8 engine to make way for an electrified four-cylinder unit for the next model year. Thus, this may be the last chance for the V8 fanatics to get a hold on one of the last few Mercedes growling V8 engines to enjoy the throaty exhaust note. Also, if you are in the market for a performance-oriented compact sedan, the AMG C 63 is the best compact sedan that is available in the market today.

Expert Review, Pricing Analysis and Buying Guide

Offered in two different variants with varying levels of performance, the AMG C 63 sees only minor changes for the 2021 model year. The 4.0-liter twin-turbo V8 in two states of tune remains as it is, while the interior sees the 12.3 digital instrument cluster and a panoramic sunroof being offered as standard this year. The prices start at an MSRP of $69,650 for the base variant, which manages to undercut all its direct competitors which include the Alfa Romeo Giulia Quadrifoglio, the Audi RS 5, and the most popular BMW M3

Mercedes offers the C 63 sedan in two variants, the base, and the C 63 S variant. The base gets almost all the features and technology that is on offer with the V8 engine producing 469 hp as standard. The C 63 S variant gets a handful of additional features, while the V8 engine produces a whopping 503 hp. There are a few safety features and other interior and exterior option packages available for an additional premium.

Which trim should you buy?

Since most of the features are already on offer on the base trim itself and the available power and performance in the base trim is sufficient for almost all circumstances. The options packages and features also charge a premium and hence is better to just opt for the base trim and save some of your hard-earned money. 

Engine and Performance

The Mercedes-Benz AMG C 63 sedan is offered with a 4.0-liter twin-turbo V8 engine under its hood that is mated to an AMG SpeedShift MCT 9-speed automatic transmission which powers the rear wheels. The engine is available in two states of tune, the base trim generates a strong 469 hp and 479 lb-ft while the higher S variant produces a whopping 503 hp and 516 lb-ft of torque. Rear-wheel drive is standard with no option available for the 4-Matic all-wheel drive.

There is no lack of performance from this V8 in either state of tune, and the 0-60 mph sprint in under 4 seconds and a top speed limited to 155 mph with the base trim is enough to justify that. The higher-powered engine reduces the acceleration times even further and increases the top speed to 180 mph. The lack of a manual gear shift option does upset a lot of enthusiasts, but the transmission is no slouch in any way and does its job rather effortlessly, no matter the driving style.

Both the Mercedes C 63 and the BMW M3 are priced very competitively against one another and the higher torque output from the AMG’s V8 makes it one-tenth of a second quicker to 60 mph as compared to the bimmer, which is the only car to offer a manual transmission. The Alfa Romeo is the quickest of the lot while the Audi RS5 is right behind it and both of them employ a much smaller capacity engine and yet are priced at a much higher cost. 

How does the 2021 Mercedes-Benz AMG C 63 Sedan handle?

Mercedes and its AMG performance wing have been trying to play catch up with the BMW M3’s handling and driving dynamics and although the gas has reduced a lot in recent years, it still isn’t the best in the segment. The standard adaptive dampers offer a comfortable and luxurious ride in comfort mode and tighten up well when driving aggressively, making it a perfect combination of agile handling and a comfortable cruiser.

The body is well controlled with no body roll at all. The steering is light and precise and the driver does not feel the heft of the car because there is hardly any feedback from the electric-powered steering. But then that is mostly the case with electric steering cars. Overall the Mercedes-Benz AMG C 63 sedan is a great handler and a perfect choice for someone who prioritizes comfort as much as handling. 

2021 Mercedes-Benz AMG C 63 Braking Performance

The C 63 S variant comes with a set of carbon-ceramic brakes and dynamic engine mounts as standard to offer precision handling and braking performance. That being said, even without them, the base C 63 performs really well with the standard 14.2-inch front and rear brakes. The almost 4,000 lbs of the weight of the C 63 does not impose any performance issues in this regard and provides smooth, progressive, and precise braking.

The BMW M3 is on the lighter side of the scale in this segment and yet employs much larger brake rotors which translate to phenomenal braking performance. The Giulia Quadrifoglio has the shortest braking distance at just 101 feet which is just a foot shorter than the BMW. The Audi RS5 weighs the most and offers the smallest brake rotors and hence travels the farthest when panic braking from 60 mph. 

Fuel Economy

The fuel economy of high-performance sedans is never really a big question of interest for most buyers. But that does not mean Mercedes compromises in this regard at all. Despite the staggering power output, the twin-turbo V8 engine manages to return a respectable 21 mpg in combined city and highway driving conditions in both states of tune. The large 17.4-gallon fuel tank means one can consistently get around 350 miles of driving range on a single tank of gas.

The M3 struggles in this regard and has the highest fuel consumption amongst the cars present here. Both the Alfa Romeo Giulia Quadrifoglio and the Audi RS5 have very similar fuel economy figures which are a tad bit lower than what the AMG C 63 returns. The smaller tanks on all the other sedans also affect the driving ranges and together, the BMW M3 has to compromise the most in this department. 


The cabin quality of a Mercedes can never be pointed fingers at and the flagship C-Class is the prime example of that. The 12.3 digital driver’s instrument cluster is now standard this year, which together with the large infotainment system at the center of the dashboard and the 64-color ambient lighting, offers the ultimate luxurious experience. The tech-savvy interior with sophisticated designs offers a very pleasant experience for all the occupants.

The premium upholstered seats with multiple ways of power adjust and memory functions for all things around the driver offer one of the best experiences for the drivers. There is plenty of room for all the occupants, but the sloping roofline does impede on the rear headspace and might be a concern for taller passengers. The 12.6 cu-ft of trunk volume is on par with the segment and the rear seats can fold down to open up more space when needed.

The BMW M3 is the class leader in this section too as it offers the most spacious front and rear seats with no compromises on the headroom either. The Audi RS5 feels the most cramped here as it offers the least amount of headroom and legroom for both front and rear occupants and also has a smaller boot. The Alfa Romeo Giulia has the best legroom at the front but has limited headroom on offer.

What’s there to keep you entertained?

Mercedes’ decision of holding back the far more superior MBUX infotainment system for the next-gen 2022 C 63 has hurt many purists and hence the 2021 model year makes do with the older touchpad-based COMAND infotainment system. Although the graphics are pretty neat and sharp, the interface isn’t very intuitive and is slow to respond on many occasions. Audiophiles would really enjoy the Burmester sound system along with a long list of technology on offer.

That being said, functions like navigation, Wi-Fi hotspot, and the wireless charging pad are all optional and need shelling out more money.

  • 10.25-inch COMAND infotainment system
  • Apple CarPlay and Android Auto integration
  • Bluetooth technology for hands-free phone and audio streaming
  • HD Radio and SiriusXM Satellite Radio
  • 13-speaker Burmester Surround Sound System
  • Turn-By-Turn Navigation Directions
  • Mercedes Me connect Mobile Hotspot Internet Access and Tracker System

The exterior design of the Mercedes-Benz AMG C 63 gives out very few clues regarding the performance it hides underneath its hood. The looks are far too subtle for our liking as one needs a second look at the car to properly differentiate it from the lower C-Class sedans. The large blacked-out 18-inch on base and 19-inch wheels on the S variant with the slightly flared-out wheel arches are one of the giveaways.

There is also the Panamericana grille, a massaged hood alongside and LED lighting all around, alongside the fender badging that discloses its true personality. The rear features fake air vents, trapezoidal quad-exit exhaust tips, and an angry diffuser while the trunk-mounted lip spoiler gives it a sporty appeal. For the 2021 model year, Mercedes is offering the large panoramic glass sunroof as standard.

The larger cabin space inside the M3 is due to the larger overall dimensions of the car, and BMW has done well to keep the weight pretty low which further aids it in the handling department. It also offers a very usable ground clearance, which is only marginally lower than the Audi RS5. The Mercedes AMG C 63 rides the closest to the ground with Alfa Romeo also offering a hunkered-down stance.

Similar to other low volume high-value cars, the AMG C 63 sedan hasn’t been tested by either the NHTSA or the IIHS, but the regular C-Class sedan on which it is based gets a “Top Safety Pick+” rating from the IIHS which should ensure the safety parameter of this car. The only downside is that Mercedes offers many features like lane change assist, adaptive cruise control, and other driver aids with a semi-autonomous driving mode as an option with its Driver Assistance package. The list of available safety and other driver assistance features has been listed below. 

  • ESP w/Crosswind Assist Electronic Stability Control (ESC)
  • Active Brake Assist with Autonomous Emergency Braking
  • Mercedes Me connect Emergency SOS
  • Blind Spot Assist
  • Back-Up Camera
  • Tire Specific Low Tire Pressure Warning
  • Optional Available adaptive cruise control with semi-autonomous driving mode

2021 Mercedes-Benz AMG C 63 vs Alfa Romeo Giulia Quadrifoglio

The Alfa Romeo Giulia Quadrifoglio may cost considerably more than the AMG C 63 sedan, but for that much money, it offers plenty more power and much quicker acceleration timings. It also offers superior braking performance and does not compromise much in terms of fuel efficiency as well. The cabin and trunk too are equally spacious and offer a tighter ride and handling which makes it more fun to drive.

2021 Mercedes-Benz AMG C 63 vs Audi RS5

Although the Audi RS5 costs a lot more than the AMG C 63, the acceleration and braking performance is pretty similar for both. The Mercedes is also marginally more frugal and also offers a longer driving range, reducing the gas station visits. Audi’s cabin offers more technology and the infotainment system is far more superior, but the lack of space all around is a huge letdown for the Audi. Therefore, the RS5 does not feel worth the additional costs, and the AMG C 63 should be the preferred choice.

2021 Mercedes-Benz AMG C 63 vs BMW M3

Priced very competitively against one another, the battle for supremacy in the compact European performance-oriented sedan cannot get any better than this. The availability of a manual gearbox with the BMW M3 and a stiffer chassis for superior handling makes the M3 more appealing for many. A muscular and distinctive exterior design and a premium, spacious, and feature-loaded cabin are other added attributes for the M3. If the lower fuel efficiency and stiff ride quality do not scare you, there is no way the AMG C 63 dethrones the M3 from its top spot. 



Final Verdict

The 2021 Mercedes-AMG C 63 sedan offers everything that one might ever need from their performance-oriented compact luxury sedan. The car is comfortable and agile to handle, the powertrain is potent enough to give most of its rivals a run for their money, the cabin is spacious and luxurious with a striking exterior design. The trunk is large enough to fit luggage for a small family for the weekend while the higher fuel economy makes it practical for daily usage as well. What more could you ask for from one sedan?
