Mercedes Benz initially came out with the GLC in 2016. It replaced the aging GLK Class which was incurring a huge drop in its sales numbers. With the GLC Coupe, Mercedes managed to combine the practicality and worthiness of the GLC SUV with a stylish and sporty coupe design. Since the day it was first launched, the GLC Coupe has raised a few eyebrows, to say the least. But so has every other “Coupe SUV”.

Expert Review


Overall Rating

In 2019, the GLC remained one of the highest-selling models from Mercedes. And for 2020, Mercedes has tweaked a few things here and there in a bid to keep its customers interested. This Benz is powered by a 2-liter inline-4 turbocharged engine which is accompanied by a 9-speed automatic transmission. In addition to this, the GLC Coupe is also equipped with some of the most advanced safety features in the whole automotive industry.

The GLC is offered with Mercedes’s 4MATIC all-wheel-drive system for those who like to ditch the highway on sunny days. Mercedes has been spearheading the “Coupe” SUV and Sedan segment for some time now. Even though the sales numbers are steady, they are a big let down. The GLC is accompanied by SUVs like the BMW X3, the Audi Q5, and the Volvo XC60 in the segment. All of these vehicles offer an all-wheel-drive system with go-anywhere capabilities.

2020 Mercedes-Benz GLC-Class Coupe Engine and Performance


The Mercedes Benz GLC is powered by a 2-liter inline-4 powerhouse. The engine works in tandem with a 9-speed automatic transmission. This powertrain manages to churn out a maximum of 255 horsepower at 5800rpm. All of the 255 horses would come in handy if you do decide to take your Merc off-road. The four cylinders also manage to pump out 273 lb-ft of torque.

As far as the gearbox is concerned, the 9-speed automatic unit feels like an absolute gem. The gearbox doesn't feel hesitant to go through all of the gears. You might be cruising in the 9th gear, however, as soon as you floor the pedal, the gearbox shifts down in a fraction of a second and launches the car ahead. The gearshifts are seamless and there are no jerks whatsoever. Even in heavy traffic, the vehicle feels calm and composed.

In terms of technical specs, there is not a lot to differentiate these vehicles. All the cars in this bunch are powered by 2-liter inline-4 engines. Even the power and torque figures from these engines are quite similar. The Mercedes narrowly beats the competition. None of these vehicles are exactly "powerful" however, they do have enough punch to get you through the day.

How fast off the line is this Merc?

When it comes to acceleration figures from the go, there is not a lot to expect from an SUV. The 2-liter bi-turbo motor manages to push the GLC to 60mph in 5.8 seconds. The GLC crosses the quarter-mile mark in 14.6 seconds. These numbers might not feel extraordinary but for a small luxury SUV, it is pretty good.

Even if you floor the throttle, the motor never feels out of breath and manages to pull the vehicle at an impressive pace. While these numbers might not matter the most for the GLC, it always feels good to have a vehicle that can pin you in your seat (to a certain extent).

The Merc, when compared to the competition, does pretty well. Only the Volvo manages to beat the GLC in terms of 0-60 acceleration. The Audi manages to run the quickest quarter-mile in the group mainly due to its Quattro all-wheel-drive system. The Audi takes 14.5 seconds followed by the Merc’s 14.6, then the Volvo at 14.9 and BMW comes last at 15.1 seconds. 

These numbers don’t really matter all that much as these vehicles are not meant to make runs down the drag strip. They are meant to haul your family from point A to point B and they are very good at doing that.

How well does it stop?

With all the weight these small luxury SUVs carry, it is imperative that they are equipped with brakes that complement the other aspects of the vehicle. The GLC is equipped with 13.5-inch rotors in the front and 12.6-inch rotors in the rear. These brakes manage to bring the GLC to a complete stop from 60 MPH in 115 feet. The GLC is equipped with Anti-lock brakes on all four corners that add to the safety aspect of the vehicles.

2020 Mercedes Benz GLC SUV Front Brake Rotor is 13.5 sec

As expected from any family vehicle, the GLC is equipped with traditional steel rotors. However, the discs are cross-drilled. This helps in better heat dissipation and reduces brake fade over a longer period of time. The GLC weighs in at 3891 lbs which makes it comparatively lighter than the competition.

The Volvo has the largest front brake rotors in this group. At 13.5 inches, the GLC’s rotors are only a tiny bit smaller than the Volvo’s. Even though the Mercedes weighs the least in this group, it takes the longest distance to stop. The Benz could have been equipped with better brakes. 

How fun to drive is the GLC300?

The 2020 GLC 300 offers two dynamic driving modes- Normal mode and the Sport mode. The normal driving mode allows responsive steering and comfortable ride. However, as soon as you flick it into the sports mode, the suspension stiffens up and the steering starts to offer a better response. Having said that, being what the GLC Coupe is, the steering response is still limited and might feel a little dull to some.

2020 Mercedes Benz GLC SUV Rear View

With the kitted 4Matic system, it tackles even the steepest of turns while still maintaining its stability. Run it over bumps or potholes, it gracefully tackles the wobbles and jiggles with poise. The Mercedes drives like a luxury crossover and rightfully carries the claim of being one of the most comfortable option in the market. It might not be or feel as agile as a proper sports car, however, considering the size, it fairs pretty well.

2020 Mercedes-Benz GLC-Class Coupe Fuel Economy


A lot is expected from a small luxury SUV in terms of fuel efficiency. They are meant to haul your family around while being comfortable, spacious, safe, and fuel-efficient. The GLC manages to offer comfort and space. In addition to that, the GLC Coupe also offers a ton of safety features as standard and lots of add on packages as well. The GLC Coupe is also pretty good when it comes to fuel economy. The GLC returns 21 miles to the gallon in the city and 28 miles to the gallon on the highway. This Merc offers 24 miles to the gallon combined.

All the other vehicles in the bunch offer a similar fuel economy. The Volvo is slightly better than the Mercedes in terms of fuel economy. There is still not a lot to differentiate the vehicles. With an increase in the competition throughout the industry, this is exactly what is to be expected from the manufacturers.

2020 Mercedes-Benz GLC-Class Coupe Interior


Inside, the Mercedes GLC Coupe is as luxurious as the rest of the SUVs in its class while remaining roomy. The GLC coupe might offer slightly less headroom to the rear seat passengers when compared to the basic SUV. This can be blamed on the sloping roof "coupe" design. The cabin impressively cancels noise from the outside remaining the ever-plush crossover the marque markets it. 

2020 Mercedes Benz GLC SUV Front Seats

The seats offer plenty of comfort and support to the occupants. In terms of room, the cabin feels pretty spacious and roomy. For the front seats, the headroom feels adequate even for taller passengers. However, as mentioned above, the same cannot be said for the rear seats. In terms of legroom, the front seats offer an adequate amount. Come to talk about the rear seats and you might be disappointed, to a certain extent.

In terms of space, the Audi Q5 offers the most room to the front and rear-seat passengers. The Mercedes Benz GLC falls last with the least amount of space on offer for the passengers. However, if better tech, space, and comfort is what you are looking for, the upcoming GLE Coupe might be a valid upgrade. Yes, it is expected to be more expensive than the GLC, it will also offer better tech and more comfort.

Creature comforts on offer

  • Power front seats with driver-seat memory
  • Dual-zone automatic climate control
  • Remote Start via Mercedes me Mobile App
  • Heated front seats
  • 40/20/40-split rear seats with power folding
  • Power-folding side mirrors
  • Power liftgate
  • Household-type 115V power outlet
  • Illuminated entry system
  • HomeLink garage door opener
  • Brake HOLD feature

What's there to keep you entertained?

The infotainment system of the 2020 Mercedes Benz GLC 300 Coupe SUV is probably of the most advanced systems on offer in today's market. However you might take some time to adjust but eventually, you’ll get a hang of it. This 10.25-inch “MBUX” infotainment system really is a gem. It is buttery smooth to use and offers immediate feedback to your touch. The screen is bright enough to be visible even if the brightest of environments.

In addition to the MBUX is a 12.3-inch digital instrument cluster that offers a ton of useful information to the driver. This cluster is highly customizable as per the driver's needs. To some, this huge glass panel might feel a little overwhelming. However, the fact that both these screens can be controlled and operated completely through the steering wheel adds to the ease. The trackpads located on the steering make it very easy to control both the instrument cluster as well as the infotainment system.

The standard infotainment features that are available in this luxury crossover are -

  • Apple CarPlay
  • Analog gauges with high-resolution multifunction display
  • 10.25-inch touchscreen multimedia display
  • Mercedes-Benz User Experience (MBUX)
  • Voice Control with Natural Language Understanding
  • "Hey, Mercedes" keyword activation
  • Steering wheel with Touch Control Buttons
  • Touchpad controller
  • FrontBass system
  • Android Auto
  • Bluetooth audio streaming
  • Dual USB audio ports
  • HD Radio receiver
  • Hands-free Bluetooth interface

How much cargo can it store?

When we talk about SUVs, the cargo capacity really matters a lot. In terms of cargo capacity, the Mercedes might not be the best in the business. With 19.4 cubic feet of cargo capacity, the Merc fails to even come close to the other vehicles in this bunch.

In terms of cargo capacity, the Volvo XC60 is the most practical in this bunch. It offers 29.7 cubic feet of cargo storage. The BMW is a close second with 28.7 cubic feet. The Audi and the Merc offer 25.1 and 19.4 cubic feet of storage respectively. The Volvo offers the most cargo volume mainly due to the boxy shape.

2020 Mercedes-Benz GLC-Class Coupe Exterior


Mercedes launched the facelifted version of the GLC for the 2020 model year. The Mercedes Benz GLC 300, though it looks small, it looks quite bulky and beefed up on the sides. Flanked by LED headlamps with the large Silver Arrow insignia resting in the center, the crossover embraces curvy lines and hard design elements. With large fenders sheltering atop 19" wheels, the SUV is undoubtedly handsome and defined. The sloping roofline might look cool but eats up into the practicality of the vehicle.

The 2020 GLC Coupe looks pretty good from the outside. There are subtle lines that follow throughout the side of the car. The side skirt with the rubber accents only adds to the visual appeal of the GLC. The big front grille with chrome inserts and the aggressive bumper give this crossover a menacing look.

The Volvo XC60 is the longest in this bunch with the longest wheelbase. This is also the reason why the Volvo offers the most interior space to its passengers. All the other vehicles are fairly matched in terms of exterior dimensions.

2020 Mercedes-Benz GLC-Class Coupe Safety


The 2020 Mercedes Benz GLC Coupe has not been rated by the NHTSA or the IIHS. Having said that, based on the crash scores of other Mercedes Benz vehicles, the GLC can be expected to be pretty good on the safety front. To add to that is the long list of safety features and tech offered by Benz both as standard and as part of optional paid packages. The GLC Coupe is loaded with a ton of active and passive safety features.

Safety Features

  • Active Brake Assist
  • 7 Airbags
  • LED headlamps and taillamps
  • Blind Spot Assist with Exit Warning Assist
  • Crosswind Assist
  • Adaptive braking technology
  • Brake Assist
  • Electronic Stability Program (ESP)
  • Aluminum and high-strength steel body structure
  • Advanced Tire Pressure Monitoring System
  • Antitheft alarm system with remote panic feature

2020 Mercedes-Benz GLC-Class Coupe Competition

Mercedes-Benz GLC Coupe vs BMW X3

Both the GLC and the X3 are very impressive vehicles. Both of them offer a substantial amount of luxury and comfort to the passengers. In terms of money, the GLC Coupe costs more than the BMW X3. As far as ride quality is concerned, the GLC is slightly better. When it comes to technology, both the Merc and the BMW are very well matched with the MBUX and iDrive infotainment systems.

Mercedes-Benz GLC Coupe vs Audi Q5 

The Q5 and the GLC Coupe are the best from their respective brands in terms of what they offer. On paper, the Audi manages to beat the Merc in every segment. The Q5 delivers better mileage, performance and interior space. The GLC, on the other hand, offers a more luxurious interior but misses out on interior space and cargo-hauling capacity.

Mercedes-Benz GLC Coupe vs Volvo XC60

The Volvo XC60 offers a very simple, clean and aesthetic look with its simple lines and curves. The Merc, on the other hand, flaunts a lot more in terms of looks. When it comes to interiors and ride quality, both the Volvo and the Benz offer a very comfortable and luxurious ride. Again, the Mercedes misses out on interior room and cargo volume. 

2020 Mercedes-Benz GLC-Class Coupe Final Verdict

While a lot cannot be said to differentiate these vehicles, “Coupe SUVs” just doesn’t make any sense. The 2020 Mercedez Benz GLC Coupe offers the same power and performance as its SUV sibling. Having said that, in a bid to make a look slightly sportier, Mercedes has made it less practical in terms of rear-seat headroom and boot space. This might be a turn off for a lot of people. To add to that, it costs considerably more than the standard GLC. The Audi Q5 is the one to go for in this bunch. Having said that, in case you demand more power and performance, the 2020 GLC 63 Coupe might be the one to go for. In addition to that, if more comfort and better tech is your forte, you might want to wait for the GLE Coupe to be launched in the USA.
