Considered as one of the most stylish cars in the Mercedes line-up, the CLS Coupe is indeed one of its kind Mercedes ever made. Since its unveiling back in 2006, the CLS was one of the very first cars to spark the “coupe-sedan” rage. Over the years, the CLS has only walked forward to chisel down its sharp propositions. The current 2020 Mercedes-Benz CLS is now in its third generation that spun off in 2019. 

No argumentation and the third-gen CLS looks stunning from every angle . Thanks to its thorough redesign. It's now more sleeker, edgier and has gained even better road presence. Stii fresh with the updates though, the 2021 Mercedes-Benz CLS is a carry-over model as well. However, this time around with an enhanced feature suite.

Overall Rating

Apart from its flashy exterior silhouette there's a lot more that the CLS has to offer. This exotic 4-door coupe sedan not only gets a luxurious and very premium cabin but also a great balance between ride and handling. However, with powerful engine options, this beauty can happily indulge in some rapid sprinting. At times though when you are more in a relaxed state of mind, the CLS rewards you with a hushed and cushy ride as it should in its class and price. However, because of its sloping outfit, it might not be the best adobe for taller passengers. 

Being a Mercedes though, the CLS also packs a ton of intuitive tech and driver -assisions at your disposal. After all, the “S'' in the CLS name is reminiscent of Mercedes’ top of the line presentation. In case of the CLS though, it does come with some exotic icing as well. Not the lone ranger on the run, and yes like every other car, the CLS does face a stiff competition. With similar schooling, the likes of Audi A7, bw 640 and even the Jaguar XF lock their horns with the CLS. How well the 2021 Mercedes CLS fares against its rivals, we try to find out here.

2021 Mercedes-Benz CLS-Class Pricing and Features


The 2020 Mercedes-Benz CLS coupe is available in a single trim option as usual. The 2020 model is priced at $69,200, but owing to the minute feature updates, the 2021 Mercedes CLS could well start from $71,000. This CLS 450 model gets a number of advanced features such as LED headlamps, LED tail lamps, 19-inch alloy wheels, and many other features and equipment. Even on the creature comfort front, the CLS 450 comes aptly loaded with everything you could expect at this price. This model can also be had with a number of optional add-ons to make it a better package.

19-inch twin-multi spoke wheels

Leather-trimmed steering wheel


ECO Start/Stop system


13 speaker Burmester premium audio


Dual-zone automatic climate control

Primarily offered with a standard rear-wheel-drive, the CLS 450 can also be hooked with an optional AWD system. However, for that you need to churn out extra $2500. Apart from the 450, there's also a bonkers CLS 53 AMG with a twin-charged 3.0-liter inline-6. However, owing to its performance orientation, it's an altogether different thing on the road which we have reviewed separately. 

2021 Mercedes-Benz CLS-Class Maintenance, Reliability and Warranty

While the Mercedes-Benz CLS coupe may not be the most reliable German car in the country right now, the car does enjoy good popularity. Thanks to its decent reliability and supreme after-sales service. The 2020 Mercedes-Benz CLS coupe is practical, comfortable, and fairly reliable and with the 2021 update, we expect it to get even better. The Mercedes-Benz CLS coupe used parts and components of great quality and ages well over time. In addition to this, this great car is backed by trustable after-sales support and a well laid out workshop network.

Talking about the maintenance costs, the Mercedes-Benz CLS coupe uses parts of extremely high quality which have a long service life but are priced at a high premium. This means that the parts replacement bills of the car will not be cheap in any sense. The 2020 model is priced at $69,200 and we expect similar pricing for the 2021 model. As per the data available on the NHTSA website, there were no recalls issued for the 2020 Mercedes-Benz CLS coupe which clearly indicates the overall quality levels of the car.


The Mercedes-Benz CLS coupe is one of the best built cars in the segment for sure. The aforementioned statement is backed by the brand’s reliable and trustable after sales support provided by the brand. While the warranty coverage of the Mercedes-Benz CLS coupe may not be the best in the segment, the car does get a limited warranty for four years or 50000 miles while the powertrain also gets the same warranty coverage. It is worth noting that there is no complimentary scheduled service package on offer. 

  • Limited warranty covers four years or 50,000 miles
  • Powertrain warranty covers four years or 50,000 miles
  • No complimentary scheduled maintenance

Under the standard warranty, the owners of the vehicle are covered for any kind of malfunction which may occur in the vehicle. The brand offers one of the best dealer networks and after-sales support which will surely help the buyers maintain this car in the longer run.

Miles Per Dollar

The Mercedes-Benz CLS coupe scores good in terms of overall built quality and reliability. The car gets great quality components which often are very durable and reliable. Apart from the scheduled maintenance, the car will not require anything extra if driven carefully. In ideal conditions, expect to spend around $3-4 Dollars per mile you travel which not only includes the gas but in addition to this, also includes the consumables, tires, and other wear and tear.

2021 Mercedes-Benz CLS-Class Buying Advice

Considering the package that the Mercedes-Benz CLS coupe comes with, the car comes out to be one of the best choices in the segment as it not only gets a great design language but also comes with a premium cabin and capable mechanicals. The driving experience of the Mercedes-Benz CLS coupe is worth mentioning here and with the 2021 update, it is expected to get even better. Overall features available with the car are great and the package is more value for money than any of its rivals.

Is buying a used Mercedes-Benz CLS coupe a good idea?

While the car scores high in terms of overall reliability and practicality, maintaining it, in the long run, may not be a very practical option. This is because of the fact that spare parts and scheduled services are not cheapest in the segment. In addition, the cars from the brand do not top the reliability charts which make it a not so good option to go for in the used car segment. However, this case is similar with most of the German automobiles. 

2021 Mercedes-Benz CLS-Class Engine and Performance


Powering the 2020 Mercedes-Benz CLS coupe is a 3.0-L turbocharged inline 6 gasoline engine. This 3.0-L pot churns out 362 hp while the peak torque output stands at 369 lb-ft and comes mated to a 9-Speed AT. Performance is great, and enthusiasts will love pushing this engine to its maximum limits. 

2021 Mercedes-Benz CLS-Class Sedan has 3L engine

The power to weight ratio of the vehicle is great and results in brisk acceleration and impressive performance. Low-end power delivery is good, but being a turbocharged engine, it shows its potential in the mid-range. The gearbox offers quick shifts and helps the driver extract the most power from the engine. The car will feel at home in the city, due to its good drivability, but the powerful engine makes it more suitable on the highways as the performance from this engine is supreme. The 2021 model of the car is expected to get similar powertrain options.

With similar attributes, it's no surprise that all the other cars in the lot here do have a similar power output. Not as good as the Jaguar XF but the CLS is one of the most energetic and refined powertrains that one could grab in this segment. While the BMW 640i might have a better punch down the lower rev range, the Mercedes CLS turns out to be the most playful around highway speeds. 

2021 Mercedes-Benz CLS coupeAccelerations and Braking Performance

If the performance figures are taken into consideration, the Mercedes-Benz CLS coupe is one of the fastest in the segment. The car does a 0-60 mph run in just 5.1 secs while it completes the quarter-mile run in just 13.6 secs. These numbers might not be segment-leading, but are sufficient for a car of this size. 

2021 Mercedes-Benz CLS-Class Sedan accelerate 0-60 mph in 5.1 sec

All four wheels on the 2020 Mercedes-Benz CLS coupe come with ventilated disc brakes along with many features such as ABS and EBD to enhance the overall braking capabilities of the vehicle. The car completes to a complete halt from 60 mph to 0 mph with 117 ft, which is considerably lower than the BMW 640i gran coupe.

While straight-line performances of all the rivals are somewhat identical, there is a noticeable variation in the braking department here. Thanks to the varying weight and weight distribution across all the cars here. Though the difference is not of a very great margin. To sum it up, all these four cars here are more or less identical when it comes to business on the ground. 

2021 Mercedes-Benz CLS-Class Fuel Economy


The powerful engine and heavyweight of the vehicle takes a considerable toll on the overall fuel economy of the Mercedes-Benz CLS Coupe. The car delivers a mileage of 18 miles to a gallon inside the city while out on the highway, it does 26 miles per gallon. We expect the 2021 model to offer similar fuel economy figures. Thanks to the continued and familiar powertrain though.

While the CLS might not be the most efficient in its segment but it all feels good and comparative in lieu of its overall equation. However, if you are more on the frugal side of things, the Audi A7 should happily please you with its best in class 25 combined mpg. Not only that, the A7 also has the longest driving range in its class despite a smaller fuel tank than the CLS. 

2021 Mercedes-Benz CLS-Class Interior


The 2020 Mercedes-Benz CLS coupe scores are very high in terms of interior comfort, practicality, and overall functionality. The interiors are luxurious and of high quality. In addition, bright interiors make the occupants feel calm inside the cabin. The cabin feels extremely luxurious and well built – all thanks to the use of high-quality plastics and materials for the construction. With the 2021 update, the car will offer a similar package if not better.

At the front, the seats are comfortable and the seats provide the right amount of cushioning to its passengers. Ingress and egress from the car are easy because of the high stance and overall, the interiors are decent. Even with a cabin that is very comfortable and feature-rich, it is the rear seat bench which has impressed us with supreme comfort and proper support all around. The Mercedes-Benz CLS Coupe is a highly practical vehicle for day-to-day use.

In terms of creature comforts as well, you get a fully loaded vault with the CLS. Amenities like power-adjustable front seats with heating and ventilation, automatic climate-control and heated steering wheel are on easy tap. While the seats and ride quality of the 2021 Mercedes CLS could be best stated as sumptuous, things get a bit worrisome in terms of cabin space. Yes, the sloping roof-line does consume a lot of headroom allowing for the smallest headroom in the segment at both the rows. 

Legroom at the front is okay but you wont get enough space at the rear to stretch your legs on longer journeys. Style and flash do come at a cost, remember that. Rivals like the BMW 640i and Audi A7 are more promising than the Merc in that regard. However, the CLS compensates things well with its decent storage spaces. There is a huge storage bin in the center console below the driver’s armrest and other small places to store some tiny stuff. Disappointingly though, where rivals like the BMW 640i and Audi A7 offer mammoth 31.0 and 24.9 cu-fts of cargo space, the CLS suffocates with only 11.9. Like it or not, with no changes, the 2021 Mercedes-Benz CLS would retain all its essentialities. Some of its interior highlights are mentioned below:

  • Power front seats with memory
  • 3-passenger rear seat
  • Dual-zone automatic climate control
  • 3 years of Mercedes me connect services
  • Mercedes me connect Assist Services
  • Remote Start via Mercedes me Mobile App
  • 64-color LED ambient lighting with illuminated vents
  • Heated front seats
  • 40/20/40-split-folding rear seats

How’s the 2021 Mercedes-Benz CLS coupe’sinfotainment system?

The Mercedes-Benz CLS coupe gets a 12.3-inch high-resolution central display which gets a number of modern connectivity features and a great sound output. The car also gets a COMAND system with a touchpad controller. Thankfully, the infotainment system could now be operated through touch inputs compared to the sole rotary-dial dependability of its predecessor. As standard, the Mercedes-Benz CLS coupe comes with a 9-speaker sound system which can also be upgraded to a 13-speaker Bermest premium audio system.

On the connectivity front, you get Apple CarPlay and Android Auto, WiFi hotspot, head-up display and wireless charging. Apart from these, the infotainment suite in the 2021 Mercedes CLS gets some other revisions as well. The latest MBUX system supports navigation with augmented reality and live traffic data. Another significant addition is the new standard 12.3-inch digital drivers display. Being the best infotainment in the market today, the MBUX has always greeted us with intuitively and sharo responses and the latest system in the 2021 CLS should be no different. 

Notable highlights of the infotainment system include the following:

  • 12.3 high-resolution central display
  • Analog gauges with high-resolution multifunction display
  • COMAND system with touchpad controller
  • Steering-wheel Touch Control Buttons
  • 13-speaker Bermester premium audio
  • COMAND navigation
  • No-charge online navigation map updates for 3 years

2021 Mercedes-Benz CLS-Class Exterior

The strongest point about the Mercedes-Benz CLS coupe is the overall design language of the car which makes it look elegant and smart. The sharp cuts and lines give it a little aggressive look which enhances the road presence of the vehicle. The side profile is smooth and sharp while the rear looks elegant and classy. The rear however is a little too busy and we would have appreciated it if the car had a little subtle look.

Carrying a dramatic yet sporty outfit since its very beginning, the CLS further polished its proportions with its third-gen redesign in 2019. The front and rear LED tail lamps are now slimmer than before and the front-grille is a bit lower and wider. The overall length does remain almost the same but the car now sits lower to the ground accentuating its grip and road presence. The front and rear bumper of the third-gen CLS have been redesigned too and in a way to make it look more aggressive than before.

Considering the dimensions of other cars in the segment, the Mercedes-Benz CLS coupe turns out to be at par with the segment standards. It is long and wide as you could expect in this class but owing to its exclusivity, it's shorter in height than some of its rivals. What that means is that you have a long and sleek exterior profile which speaks for itself. Every inch of the CLS spills premiumness and a sporting tone. While the BMW 640i and the Audi A7 too have a similar exterior profile, the CLS successfully stands out from the crowd. It's not as edgy as the A7 nor too tall like the Bimmer. In fact, the CLS fuses the design of a business-class saloon like the mercedes S class with that of a sporty coupe. 

Some of the exterior features of the Mercedes-Benz CLS coupe include:

  • 19 twin-multi spoke wheels
  • Four-door coupe design
  • Chrome diamond-block grille
  • ALL-LED exterior lighting

2021 Mercedes-Benz CLS-Class Safety

The Mercedes-Benz CLS coupe has always been one of the safest cars in the segment and features a long list of safety features and equipment. Apart from the basic features such as ABS, EBD, traction control, etc, the 2020 Mercedes-Benz CLS coupe also gets advanced features such as blind-spot assist, lane keep assist, crosswind assist, and many more. The 2021 model is expected to offer similar features. Keeping its promise of safety, the 2019 Mercedes CLS was awarded a 5-star crash-test rating by NHTSA. No mechanical changes since then and even the 2021 CLS should offer an equally strong safety suite. A list of some of the features that are offered with the Mercedes-Benz CLS coupe is given below:

  • LED Daytime Running Lamps 
  • Crosswind Assist 
  • Blind Spot Assist and Rear View camera
  • Front and rear ventilated discs
  • 7 airbags 
  • Pre and Post-collision safety system
  • Anti Lock Braking System (ABS)
  • Electronic Stability Program (ESP) 

2021 Mercedes-Benz CLS-Class Competition

Mercedes-Benz CLS vs BMW 640i 

Just like other cars in the brand’s lineup, the BMW 640i xDrive gran coupe gets sorted driving dynamics, segment-leading performance and aggressive design to give it a great road presence. If you need a fast, comfortable, and fun to drive vehicle, the BMW 640i is definitely better than the Mercedes-Benz CLS Coupe.

BMW 640i 

Mercedes-Benz CLS vs Audi A7

The Audi A7 is a premium vehicle and comes with a comfortable, practical, and highly equipped cabin. The car gets reliable engine options and delivers faster performance. The car not only gets reliable and smooth engines but also drives really well in most of the situations.

Audi A7

However, the car is not as good as the CLS coupe in terms of overall luxury levels and ride comfort.

Mercedes-Benz CLS Vs Jaguar XF S

Jaguar XF S, with the new update, remains one of the best looking cars in the segment and gets a very premium and an upmarket cabin. The car gets a comfortable cabin, fun to drive nature, powerful powertrain options and in addition to all this, also gets one of the best design cues which simply give it a distinctive character.

Jaguar XF S

2021 Mercedes-Benz CLS-Class Final Verdict

If you are looking for a business class saloon with a hint of distinctive style into it, look no further than the 2021 Mercedes CLS. While you will have to compromise a bit with cabin space if you are tall and willing to do so but you would surely be up for some very great goodies. Apart from its sleek and sloping style, the CLS offers an energetic powertrain, is easy to handle, is very premium on the inside and is economical as well. Being a top-line Merc it also gets all the creature comforts that you would expect in this price and range along with an extended suite of safety features. However, if you want something more stylish, practical and spacious, the Audi A7 would make a very good choice.
