In line with Merc’s latest launches, the 2021 Mercedes-AMG is all set for a complete revival. Apart from the striking new exterior and more premium yet tech-oriented cabin, the sports sedan gets a new engine along with the now-standard all-wheel-drive system.

Athletic, agile, brute and aggressive. These are perhaps some of the better words to describe the Mercedes-AMG C 63 sedan. Sitting somewhere between the regular “C” class range and the furious E-AMG lineup, the C 63 hits the right balance of everyday driveability, power and a tight on-road manner. Don’t you dare to misinterpret it as an “entry-level” Mercedes anymore? Yes, it does have all the characters that you would seek from a Mercedes any day. It's comfortable, looks classy, drives and rides very well and is loaded with all the latest in automotive tech as well. 

However, this was all about the current 2020 Mercedes C 63 though which is in its fourth generation. The upcoming 2021 Mercedes C-63 would still hold all the aforementioned signatories but with better style and amenities. Following the updated C-class for 2021 which might roll-off the fifth-generation of the C family, the 2021 Mercedes-AMG C 63 sedan would also be getting a thorough revision. However, for the C 63 changes would not be limited just to the interior and exterior overhaul. The 2021 C 63 sedan is reportedly going to have a 2.0-liter turbo engine and a standard AWD as well. Well. sounds too much fun on paper, we dig a bit more here and see what else might the 2021 Mercedes-AMG C 63 sedan pack in?

What’s New with the 2021 Mercedes-AMG C 63?

  • New 2.0-liter turbo engine replacing the earlier V8
  • Thorough interior and exterior restyling
  • Standard AWD system

What’s the expected price and release date of the 2021 Mercedes-AMG C 63?

Mercedes has neither acknowledged the price of the 2021 model yet, nor its release date. The 2020 AMG C 63 had an MSRP of $68,100 and the high-end AMG C 63 S had an MSRP OF $ $75,700. We can’t envisage the price of the 2021 model as there are many vital changes involved and could easily kick-in from something around $78,000. In lieu with the current market condition with respect to the ongoing pandemic, the 2021 Mercedes-AMG C 63 sedan shouldn’t hit the stores before late 2020.

What to expect in the engine department of the 2021 Mercedes-AMG C 63?

Say adieu to the traditional V-8 engine of the Mercedes-AMG C 63. Yes, a turbocharged 2.0-liter inline-4 hybrid engine is on the cards for 2021. With the number of cylinders slashed to half of the previous figure, the new hybrid inline-4 won’t generate as considerable power as the 503 hp of the V-8. But don’t write it off too soon, the new hybrid punch of the inline-4 will provoke more power and momentum, thanks to a combination of the inline-4 and a 48 V mild hybrid motor. The perk of the electric motor is an additional 22 hp and 184 lb-ft of electric boost. 

The inline engine of the 2021 AMG C 63 is based on the AMG A45 model of Mercedes-Benz. Pair that with the hybrid drivetrain and the engine chugs out about 428 hp and 553 lb-ft of torque approximately. For the transmission duty, we might get to see a new 9-speed automatic transmission as well. Well, whatever be the power output, the C 63 has been always insane with its power-delivery and punch and we expect it to blow our minds even in 2021.

While we are still not sure about the final power output of the 2021 C 63, it should certainly be something close to the Alfa Romeo Giulia Quadrifiglio’s 505 hp. Even in terms of straight line performance, the 2020 Mercedes-AMG C 63 sedan should be a tough competitor to the Quadrifoglio’s 3.8 second run from 0-60 mph.

How does the 2021 Mercedes-AMG C 63 Handle?

The 2021 AMG C 63 is looking forward to a new era of handling dynamics. With the weight of the engine significantly reduced, the AMG C 63 will deliver a more agile and breezy drive. However, we will miss the twin-turbo V-8, which zipped through the trails at a blistering pace. An electronic limited-slip rear differential is an inclusion in the 2021 model. The AMG’s ride control suspension with adaptive dampers minimizes shock for maximum sports car performance. However, this suspension had its issues, with the ride quality being harsh on appalling roads.

The AMG C 63 is a refined car though, retaining the ride quality even though it gravitates at times. The precise grip of its summer tires is exclusively for the heat of the racetrack. With the hybrid energy and the full standard AWD, the 2021 C 63 inspires confidence on the streets and even a racetrack. The biggest highlight for 2021 though would be the new standard AWD disguised as Variable Drift Mode. Not disappointing though, because you would soon have an AMG C 63 which can go RWD at the exact moment, you want it to. Now how these changes affect its real-world experience, well that could only be figured out once its finally launched. 

How many miles to the gallon will the 2021 Mercedes-AMG C 63 deliver?

As of now, Mercedes has disclosed no speculation regarding the MPG numbers with the new hybrid assist. One thing is for sure, the MPG numbers will rise significantly compared to those of 2020. We could expect to see a highway MPG over 30. The current fuel economy numbers are on par with the competition. With this current generation, the AMG C 63 could herald in a revolution with its stellar fuel efficiency.

The competition in the fuel economy is cutthroat among all these sports coupes. The Cadillac CT5-V and the Lexus GS offer the most mileage. All of this could change by introducing the 2021 AMG C 63. The 2020 AMG C 63 was one of the most fuel-efficient of the lot and expects to see a major overhaul in its fuel economy for 2021.

What to expect from the 2021 Mercedes-AMG C 63’s interior?

The interior of the AMG C 63 is a class act by itself, with beautiful craft quality and a high abundance of elite materials. The 2021 AMG C 63 will include an enormous infotainment screen positioned in the center stack. They also placed another screen for the instrument cluster. The front seats have the heating option, coming in handy for comfort on frosty days. The cabin is a mixture of luxury and sportiness with a variety of materials used like bright aluminum, Alcantara leather, and carbon-fiber.

The legroom and headroom are adequate enough for average individuals, but a fuss for the taller ones. Ingress and regress out of the vehicle are particularly easy with large door openings. The front seats feel luck for those aboard, with 14-way power adjustment and memory function to adjust as per their need. For the rough-and-tough riders, the AMG Performance seats are also available that have an additional stiffness and support.

The 12.6 cubic feet trunk space of the AMG C 63 is average in its class. It may be ample to fit in 2 luggage, but space-savvy customers may be drawn more towards the Lexus GS F. It's versatile 14.1 cubic feet of trunk space is on the wishlist of every sedan buyer.

2021 Mercedes-AMG C 63: Infotainment System and Connectivity

The infotainment supports a 10.25-inch display, which features all the driver and navigation visuals. The touchpad, or the intuitive steering wheel controls, can regulate the infotainment. The updated MBUX infotainment will be on the cards for 2021. The infotainment acts in synchronization with the 13-speaker Burmester sound system. Play the radio with the SiriusXM satellite radio service or HD Radio. Smartphone connectivity is never an issue with Apple CarPlay and Android Auto integration. The Bluetooth voice-recognition adds an authentic personal connection for the chauffeur with his Mercedes.

Navigation ensures you reach your destination through the best no-traffic routes. Other connectivity bonanzas include USB, wireless charging, and an SD card slot. The 2021 AMG C 63 expresses Mercedes-Benz’s taste of high-end automation.

Will there be any changes to the exterior of the 2021 Mercedes-AMG C 63?

The 2021 Mercedes-AMG C 63 follows suit with its aggressive sedan style. The muscular sedan has gone through an evolution with sharp edges and a redesigned Panamericana grille. The tail lamps are now slim and horizontally aligned and the body-lines are now more muscular and deeper. However, these reforms are only marginal and the 2021 model looks as good as the 2020 one. There are many factors that set the AMG C 63 apart, like the flared wheel arches, quad-exit exhausts, and exclusive multiple AMG badges placed at strategic locations all over the body. 

The LED headlights are sharply cut and blend with the front fascia to give a brute look to its face. Unique AMG 18-inch tires give a special character, while the pricier S trim gets 19-inch ones. The powerful S trim also gets intricate cuts and black gloss finishes and badges to illustrate its superiority. A variety of color choices are available to choose from, with 5 polished metallic paints to spruce up the exterior.

The 2020 AMG C 63 had the lightest curb weight in its class, which works to its advantage. With a lighter 4-pot engine onboard, the 2021 AMG 63 will cruise through highways with minimum effort. Most of the dimensions of the AMG C 63 are analogous to its rivals, which is common for the sports sedan class.

Will the 2021 Mercedes-AMG C 63 be worth my money and time?

The 2021 Mercedes-AMG C 63 is an exciting prospect for every car enthusiast this year. The exclusion of the robust V-8 will set alarms ringing in the mind of some purists, but we expect the inline-4 engine paired with the electric motor to perform better. No surprise though that the 2021 Mercedes-AMG c 63 will be as delightful on the track as its predecessor along with an extended touch of luxury and technology.
